Storing your coins safely while not risking loss of keys
This was originally an answer to a question that was asked here, but OP deleted their post. This might help some newbies (especially the multisig edit at the end), so I want to make sure it's still accessible here. The original question was whether the Electrum wallet stores a Trezor's private key when using a passphrase. OP noticed that their Trezor wouldn't connect to their Electrum wallet when entering a different passphrase than they used when creating the wallet. Thus, OP (likely) assumed that the wallet stored the private key, as it somehow knew that a different private key was now used. Here is my original answer (with some modifications): IMPORTANT: I'm assuming here that you connected your Trezor by choosing the "hardware wallet" option in Electrum, rather than giving Electrum your 12/24 seed words. TL;DR: No, your coins are safe :) I'm assuming by passphrase) you mean the 25th (or 13th) word. When you have this feature enabled, a private key gets generated every time you enter a passphrase. When you enter the same passphrase you used to create the wallet, the wallet with your funds shows up. Whenever you enter something different, a different private key is generated on your Trezor. This allows you to have multiple different wallets, for example by choosing the passphrases "First Wallet", "Second Wallet", "Third Wallet", or a secret wallet with a secret passphrase. So whenever you enter a new passphrase when connecting your Trezor to Electrum, the Trezor will send a new public key to Electrum. Electrum will then derive addresses from this public key and check those for balances. It won't find any, as you used a new passphrase. EDIT: I just realized that you said your wallet doesn't connect to Electrum when you use a different passphrase. This is simply because Electrum doesn't receive the correct public key from the Trezor and therefore Electrum thinks it's a different wallet (which it is). When you enter the passphrase you used during creation of your wallet, the Trezor will send your actual public key to Electrum, which will then find addresses with balances, which it will show to you. EDIT (to clarify): Connecting your Trezor after creating the wallet is only necessary to send funds or verify addresses, as the public key is already stored in the wallet.dat. The only thing Electrum actually stores is the public key, which can only be used to look at your Bitcoin, not to move them. You might want to keep this public key a secret as well though, since it links all your funds to you. This is what Electrum stores in the wallet.dat file, which you can just encrypt by choosing a password for it. Well done using a passphrase by the way! Should someone get their hands on your Trezor, a sophisticated attacker can get the secret key off the device in 15 minutes. Using a passphrase makes this attack almost useless, as the both secret key AND the passphrase are needed to move your funds, and the passphrase is not stored on the device. A passphrase also allows you to hide funds from potential robbers that force you to unlock your wallet. You can do this by activating the passphrase feature and sending your funds to a wallet with a secret passphrase (do NOT lose this, as losing your passphrase renders your funds inaccessible). Afterwards, you can safely deactivate the passphrase feature, so the device doesn't even ask for one should you get robbed. Simply reactivate it when you need to access your funds. EDIT: Should you be worried that you might forget your passphrase, you should look into multisig wallets. Depending on how you set this up, you can make it more secure against theft and less likely for you to lose access to your funds. Say for example you get four wallets: two hardware wallets, a well-protected (airgapped) laptop with Electrum, and a secure mobile wallet that allows for multisig (like Fully Noded). You can then create a 2-of-4 multisig wallet that requires you to sign transactions with any two of these four wallets. The increase in security comes from the fact that an attacker now needs full access to two of your devices (or their stored private keys) at once. At the same time, the fact that you yourself now also need access to only half of your devices means that in the event of a total loss of one (or even two) of them, you can still move your funds to a new wallet. As long as you do regular checks (e.g. first day of each month), ensuring that you still have access to all your devices' stored private keys, you can always catch a loss of keys and fix this without losing funds (by creating a new multisig wallet and sending the funds there). This allows you to use a passphrase on your wallets without storing it anywhere physically or digitally. This would usually be very risky, as forgetting the passphrase would lead to a loss of funds, but this risk is now close to eliminated. (The following part was not in the original answer) Some IMPORTANT general secruity tips:
Consider including trusted friends and/or family members as co-signers for a multisig wallet. This ensures that it's not even possible for you alone to hand over funds to an attacker. Depending on your level of trust, you might want to make sure that your co-signers can't collaborate to steal your funds (if you include 3 people, create at least a 4-of-n multisig). You could also deliberately make it possible for all or even just some of your co-signers to move your funds (3 co-signers, 3(or less)-of-n multisig) to make sure your funds aren't lost should pass away unexpectedly.
Consider running your own full node and Electrum server (also check the alternatives), which you connect your Electrum wallet to. This ensures that you don't send your public key to anyone else. If someone knows your public key, they know how much BTC you own, making you a potential target.
Always encrypt your wallet.dat (or whatever you called your wallet file), even if it's a watch-only wallet. This protects your public key (see 1. for why you want that).
Create watch-only wallets: Use an airgapped) device to create a wallet with Electrum (make sure to back up the seed phrase) and export the public key. Then create a new watch-only wallet on another device (like your everyday laptop) with that public key to be able to check your funds. To create the initial wallet, you can also use any other hard- or software wallet that allows you to export the master public key.
Hide, or (when using a hardware wallet with a passphrase) even delete your watch-only wallets. Hiding your funds makes you less of a target. When using a hardware wallet, recreating the watch-only wallet is fast and simple, so you don't need to store it if you don't want to check your funds every day. Note that this approach doesn't help much when you don't use a passphrase, as an attacker will obviously check the passphrase-less wallet no matter what.
Keep some funds on your hardware wallet(s). If an attackers sees funds on the wallet(s), they might not force you to enter a passphrase or ask if you have any multisig wallets (lying under pressure is hard).
Hide all your wallets in different places. If someone sees that you have multiple wallets lying around, they might realize you have a multisig wallet.
Don't risk a robber getting (for example) two keys to your 2-of-4 multisig wallet and then racing them to move your funds with the other two keys when they leave. They're gonna come back and be pissed. If it comes to this, you need protection until the robber is caught. STAY SAFE!
The easiest way to solve a problem is to never have it. Don't make yourself a target. If nobody even suspects that you have a multisig (or any wallet at all), they're probably not gonna look for it.
Please correct any mistakes you find and I will edit my post. I will also gladly add more tips to the list. I will of course credit anyone who helps. Tip for devs who want something cool and important to work on: Make the creation and usage of multisig wallets as noob-friendly as possible. If someone expresses worries about losing access to their funds by forgetting the seed phrase, wallet pin, etc. (someone in my family actually brought this up to me), multisig wallets are the perfect solution as they add redundancy.
Evo uses Proof of Stake consensus mechanism, which is different from Bitcoin's PoW (Proof of Work). Evo mining process in PoS system is called staking. The block producer will get 6.5EVO, as well as the transaction fees and gases as block reward. So the real reward is usually more than 6.5 evo in total. Basic requirements for staking：
Run a Coinevo fullnode, and keep online (Since Coinevo is using PoS, we don't need any mining machine, just PC or even Raspberry Pi can run a fullnode);
Have some EVO in the wallet (fullnode)（Any amount of EVO can be used for staking, more EVO means higher possibility to stake).
If you have no EVO yet, please get some from market before you doing following staking settings. Currently, Coinevo Core wallet is the only wallet that support Coinevo PoS staking. Note that other wallets like mobile wallet and Evo Electrum are not able to stake for the time being. Two ways to stake:
Method 1：Staking with evod, using command line, suitable for Linux/OSX/Windows/Raspberry Pi users who are familiar with command line tools.
Method 2：Staking with evo-qt wallet, with GUI, suitable for common users.
Either way works in the same way for staking, so you can choose either method you like.
Method 1：Staking with evod (command line)
1. Run evod
Follow the guidance to run evod :
Staking is default on for evod, so no need for other options if you only want to stake.
2. Send some EVO to your wallet
First you can generate a new address with：
This will generate a new address with Prefix '1'. You can send some EVO to this new generated address for staking. You can generate as many addresses as you like, and send arbitrary EVO as you like for staking. Note：The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE.. After the EVO node syncing to the latest block, you can check current balance with ./evo-cli getbalance or get utxo list with./evo-cli listunspent Please do following steps after your coin is mature.
enabled means if your wallet have enabled staking, it should be true by default. staking means if your wallet is currently staking (mining). weight stands for the amount of EVO that is staking right now, with unit 10^-8EVO, here in the example, we have 0.532EVO staking. expectedtime stands for the expected time that you will get a reward, the unit is second.
4. How to stake if the wallet is encrypted？
If your wallet is not encrypted, you can skip this section. However, for security, we recommand you encrypt your wallet. Coinevo wallet can be encrypted with encryptwallet . However, staking will be stopped when it is encrypted. For example, ./evo-cli getstakinginfo for a encrypted wallet：
See staking turns to false , which means wallet is not staking. You can use walletpassphrase to unlock wallet for staking：
./evo-cli walletpassphrase "" 99999999 true
After unlocking, you can double check getstakinginfo , it should look the same with previous unlocked result, staking become true.
Method 2: Staking with evo-qt wallet (official PC wallet)
Current supported platform: Mac/Linux/Windows.
1. Open Evo qt wallet
Launch the wallet.
2. Send some EVO to your wallet
If you already have some EVO in your wallet, you might skip this step. Note：The coin should wait for 500 blocks before being able to stake, i.e. about 17 to 24 hours to MATURE..
3. Check staking status
The flash sign at the bottom of wallet shows staking info : Solid black flash means it is staking now. For more information, you can put your mouse on the flash, e.g.:
Staking : if it is staking；
Your weight is : How many EVO are able to used for staking, unit is EVO;
Network weight is : How many EVO are staking in the network, unit is EVO；
Expected time : expected time to get reward, unit is Day.
Hollow flash measn it is not staking Possible reasons for not staking：
1.There is no coins of no mature coins (more than 500 confirmations(blocks)) -- Solution: send some EVO to the wallet and wait for 500 blocks (about 17 hours);
2.Wallet is locked/encrypted -- Solution: unlock the wallet for staking.
No flash sign means staking is disabled
3.Staking is disabled -- Solution: enable staking in the evo.conf (-staking=true)
About block reward
The block producer will get more than 6.5 EVO rewards, something to keep in mind:
The reward come from a new transaction, you can check balance to see if you get the reward.
Once succesfully stake, you will get 0.65EVO reward immediately.
Other 5.85EVO will be sent to you after 500 blocks (about 17 or 24 hours), in continuous 9 blocks, within each block you will get 0.65EVO,, so in total it will be 5.85EVO.
The staked coins (UTXO) will be locked for 500 blocks, during this period, it cannot be spent nor be used to stake.
How to disable staking?
Staking is by default enabled for Coinevo wallet. If you need to disable staking for some reason (for example exchanges are always recommanded to disable staking), you might following anyone of the 3 ways below: 1 Add -staking=false when running Coinevo node：
./evod -staking=false -daemon
For qt wallet, it is like：
2 Add config staking=false in evo.conf; 3 Encrypt wallet, since encrypted wallet will automatically stop staking.
Dr. Craig received the final key slice to access the Tulip Trust and to prove he is Satoshi VS fake news cryto dogs
I) Dr. Craig mined the first 70 Bitcoin Core blocks and more than Jan 14, 2020 he provided the documents of more than 16XXX public addresses to Ira and the Court. The US Judge decided to remove sections The information about the 16XXX blocked mined by Dr. Craig was inside an encrypted file which required 7-6 key slices to decrypt it. You can check the Court document here https://www.courtlistener.com/recap/gov.uscourts.flsd.521536/gov.uscourts.flsd.521536.211.0.pdf After Dr. Wright mined the first 70 blocks of bitcoin (the public addresses for which he has already disclosed), he implemented a unique and proprietary algorithm that he created to automate the key generation process so that each later block mined (after block 70) was assigned a different public address. From 2009 through 2010, he could view the many public addresses assigned to bitcoin he mined from block 71 (starting in 2009 to 2010) by accessing the bitcoin software on the computing devices he was then using for bitcoin mining. In about June 2011, Dr. Wrightplaced into an encrypted file
1) the bitcoin software he used;
2) software components for additional bitcoin applications;
3) his proprietary algorithm; and
4) other data from which information about bitcoin mined after block 70 could be re-generated
2) software components for additional bitcoin applications;
3) his proprietary algorithm; and
4) other data from which information about bitcoin mined after block 70 could be re-generated
III) Because Dr. Craig can access to the encrypt file content, on Jan 14, 2020 he provided the documents of more than 16XXX public addresses to Ira and the Court. The US Judge decided to remove sanctions against Dr. Craig because his 16xxxx BTC Core public addresses document complies with the Court order. IV) From the above information, this is showing that Dr. Craig can access "other data from which information about bitcoin mined after block 70 could be re-generated" which means that Dr. Carig can access to the private key for the Tulip Trust Wallet and to prove that he is Satoshi. There are many fake news crypto dogs publishing fake articles, posts on BSV channel and everywhere. Do not believe them - read Court documents and https://craigwright.net/ to know the truth.
How Ransomware Encryption Happens & 4 Methods for Recovery
We know how overwhelming it can feel to be the victim of a ransomware attack and how your business cannot operate due encrypted or locked files. This page delivers insight on why your files were encrypted or locked, and the options you have to decrypt ransomware. As a ransomware recovery service provider, we have helped thousands of clients successfully recover their data and decrypt their data. Evaluating all options will include analyzing the encrypted files, and the least desirable option to pay the ransom demand if necessary. Our process helps provide critical insight into decrypting ransomware and the available options that clients have. By the end of this piece, it is our goal to show you what is involved to successfully recover your files. This guide outlines what steps and research are necessary to decrypt or unlock your files from a ransomware attack.
You’re the victim of a ransomware attack
You arrive to work and start noticing suspicious alerts coming from your servers, and none of the databases are functional. Your co-workers are frantic and cannot access any of their data. You investigate further and find all of the files on your network are renamed and discover ransom notes, and a screen asking you to email someone if you want your data back. You finally realize that you are a victim of a ransomware attack, and all of your files are locked or encrypted.
3 Common Ways Your Files Were Encrypted or Locked
Ransomware succeeds when businesses have poor security hygiene. Organizations that lack policies & procedures around data security will have a higher risk of ransomware attacks. Here are some of the most common ways to fall victim to a ransomware attack:
Open Remote Desktop Protocol Ports (RDP)
Businesses that have improperly configured network security may leave their Remote Desktop Protocol (RDP) ports open. Unknowingly, this is the equivalent of leaving the front door unlocked when you leave your home: it provides an opportunity for cyber attacks to come through with little deterrence. Once a hacker is connected to your network, they can install ransomware and additional back doors to access your network at a later date. A large percentage of ransomware attacks still use this method of attack because so many organizations are not even aware of this security vulnerability.
Ransomware can infiltrate your network by a malicious email campaign known as a phishing attack. Ransomware operators use massive networks of internet-connected devices (botnets) to send phishing emails to unsuspecting victims. These emails intend to trick the receiver into clicking on a malicious attachment or link, which can secretly install the ransomware virus or other malware. Phishing emails are becoming increasingly difficult to detect as cybercriminals find clever ways to make a malicious email look legitimate. This underscores the importance of security awareness training for everyone in the organization, not just the I.T. department.
The ransomware operators may have used previously compromised passwords from employees at your organization to gain unauthorized access to the networks. This derives from the poor security practices of reusing the same passwords for multiple accounts and authentication processes. If your employees have been using old & weak passwords to access your business data, a cyber criminal can use a previously compromised password to initiate the attack. Remember to always to follow good password hygiene. The variety of attack vectors highlights the importance of a digital forensics investigation that can help victims understand how the ransomware came onto your computer and what steps you can take to remediate the vulnerability.
4 Options for Ransomware Recovery
In this section, we cover the options to restore files encrypted or locked by ransomware.
1. Recover files with a backup
If your files become encrypted in a ransomware attack, check to see if you have backups to restore and recover (in order).
Off-site or offline backup. Having your backup stored in the cloud or offline would protect the data from the virus since it is not accessible at the time of the attack.
Check your Windows Shadow Copies. Even though most ransomware will delete Windows Shadow Copies, you might get lucky and find them intact.
Check your on-site backups. We observe that most on-site data is either manually deleted by the attacker, or encrypted by the ransomware virus.
2. Recreate the data
Even though your files are encrypted by ransomware, you might be able to recreate the data from a variety of sources as outlined below:
Recreate the data from paper copies. When you have clean systems and physical copies of your data, you can re-enter the data manually from paper copies into your computers and servers.
Piece together data from email. Email exchanges are a great way to salvage some of your data from email attachments.
Database mining. Some ransomware variants only encrypt a small part of a database or backup files so you can pull out good, usable data.
3. Breaking the ransomware encryption
The harsh truth is that the majority of ransomware encryption is unbreakable. This impossibility is a tough concept for many of us to accept, given the technological advances of our society. Does this mean you should skip looking into whether the ransomware encryption can be broken? This option should always be explored if presented by a ransomware recovery firm, although the final choice is yours to make. We will lay out a real life example at Proven Data below to outline why this was a great decision for a company that was infected with ransomware. While it tends to be rare, there are poorly constructed ransomware encryptions that have been broken by security researchers. If you can avoid paying a ransom, you should at all costs. There can be flaws in the malware or weaknesses in the encryption. Businesses can look at these options, especially if time is on your side. There are also free ransomware decryption resources that provide tools for previously decrypted ransomware variants. A client of ours had hired a ransomware recovery company to recover their files until we discovered at the very last moment through our analysis that the encryption was breakable. With less than 20 minutes to spare, we saved the client out of paying a $450,000 ransom.
Why can’t most ransomware encryption be broken?
Ransomware is a cryptovirus, which means it uses cryptography in combination with malware to lock your files. Modern cryptography uses sophisticated mathematical equations (algorithms) and secret keys to encrypt and decrypt data. If strong encryption is used, it can take thousands, if not millions of years to break the encryption given the strength of today’s computers. Encryption is a security tool created with the intent of data protection. It is a defensive tool to provide security, privacy, and authentication. Sadly, ransomware attackers are using it as a weapon against innocent victims.
How do I know if the encryption can be broken?
You can start off with this free ransomware identification resource to determine the feasibility of decryption. You will need to upload the ransom note and a sample file into the ID-Ransomware website, and it will tell you if there is a free decrypter or if it is an unknown ransomware variant. Please note that the tool is not always 100% accurate. If the variant is still under analysis, you will need a malware or encryption analyst to determine whether or not there is a possibility for decryption. Encryption is designed to be unbreakable, which is why security researchers can’t simply make a tool for ransomware decryption. These unbreakable encryptions protect our bank accounts, trade secrets, government data, and mobile communications, among other things. It would be a significant security concern if there were a master decryption tool that could break encryption algorithms.
4. Paying the ransom to decrypt ransomware files
If the encryption is too strong, the only way to obtain the decryption key for your files is to pay the ransom. Many ransomware victims don’t have time on their side because they are facing significant business disruption. Each minute that passes could be a lost client, or worse for a medical organization. Here is a list of the most prevalent ransomware variants that are known to be “cryptographically secure,” which means that Proven Data or the security community has confirmed the encryption is unbreakable:
I don’t want to pay the hackers ransom.
Businesses and individuals have the option of choosing not to pay the ransom in a ransomware attack to regain access to their files. For personal, political, or moral reasons, there has been resentment of the ransomware economy, and victims do not have to engage in extortion. If paying the ransom is the only option, you should know what to expect before considering moving forward.
How a ransomware recovery specialist can help
If you do decide to use a ransomware recovery company and if there is one thing you get out of this article, it is this: You should always question how a ransomware recovery company is recovering your data. If you are unsure, asking the right questions will ensure a transparent experience:
How are you recovering my locked / encrypted data?
How much will ransomware recovery cost?
Do you have experience with this variant?
A ransomware recovery specialist can analyze your current situation and determine what options are available to you at the time of the inquiry. A competent and experienced ransomware recovery company should be able to provide the following:
Understanding the ransomware variant and what to expect
Malware analysis to determine if the encryption can be broken
Consultation on the attack vector which caused the attack and preventative methods
Digital currency readily available to facilitate the ransom payment expeditiously
Modification of non-functioning or poorly-functioning decryption programs that are causing delays in decrypting your files
Repairing damaged databases or files
Understanding how your files were affected by ransomware in the first place will provide you with the insight needed to prevent another attack. Whether you choose Proven Data or another company to decrypt your ransomware files, it’s important to know what unknowns there may be out there. Our threat intelligence that we’ve gathered from the thousands of previous cases enable you to make informed decisions in helping restore your data after a ransomware attack. If you require a company with such experience, we’re standing by to assist 24/7.
I think I know what happened to Peter Schiff's Wallet Password, and it may be possible to restore his access
People have been discussing Peter Schiff losing access to his wallet. Unfortunately, we in the crypto community couldn't really help without more information. I just watched the following video and Peter gives details about the wallet he had: https://www.youtube.com/watch?v=3iFolFv4RV0&feature=youtu.be&t=460 It was a wallet set up on Blockchain.com. Fortunately I've used them on and off from the beginning so I'm fairly familiar. Peter says he'd usually "enter a PIN code" but that suddenly stopped working. That's good news. I don't know how Blockchain.com has things set up behind the scenes but it doesn't seem to me Peter's wallet (the private key part) is encrypted, because a 4-5 digit PIN would be a horrible password for such a function. The PIN I believe is really just a first line of defense, just something there if, for example, a person leaves their mobile phone laying around unlocked. Blockchain.com started as a web based wallet. A mobile app which could be downloaded didn't become available until later. That's important because their security system wasn't structured around an app, but instead something like logging into a website with a username and password. For new accounts the site generated a "Wallet ID" which was a cryptic looking string of characters serving as a username. To access a Blockchain.com wallet a person would provide the Wallet ID and enter their password. That was it. There were additional security features which could be added but that was the default routine. At some point they also began mandating new accounts provide an email, which they sent the Wallet ID to (because many lost these IDs). The point is the PIN for the mobile device just authenticates using the device to connect with the Blockchain.com server. If Peter still has his device and access to the email which should have been used to set up his account, and which should contain his Wallet ID, I'd say there is a >80% chance he can regain wallet access, even without knowing the backup seed phrase. As for getting logged out of the PIN I think that's a normal security feature working as intended. It probably periodically expires or requires reset. Since Schiff takes a highly nonchalant attitude toward his Bitcoin wallet, and isn't very technical on top of that, it doesn't surprise me in the slightest that he got accidentally locked out.
Celare|The world’s first cross-chain and anonymous solutions for all assets
Celare, anonymize people’s digital assets From the internet era to the birth of blockchain, it means that all data information, including assets, has realized the phased leap from the entire network sharing to anonymous communication. Bitcoin was once considered as a secure cryptocurrency. However, the mainstream cryptocurrencies on the market always have the risk of privacy leakage, including bitcoin. That is to say, and bitcoin is not private. But based on the greatness and geeks of human intelligence, blockchain networks with complete anonymity have been developed, such as Zcash, Dash, and XMR. So is this the end of the story? Of course not. https://preview.redd.it/79vgf5bsggn41.jpg?width=1580&format=pjpg&auto=webp&s=395e2f68e266dae435b0d348d1df94762386a4cb People are surprised to find that these anonymous digital assets can genuinely realize the privacy protection of identity and transaction. And they want to share with more relatives and friends around so that this great discovery can be extended to the entire blockchain application. They faced multiple barriers across the asset chain. If you need a Blockchain system with a privacy protection mechanism and smart contracts at the same time, the traditional blockchain solution is to make significant changes to the underlying protocol, which inevitably consumes more computing resources, thus affecting the efficiency of the chain. The privacy protection of data information and assets is like the layer of wall tiles built between you and me, which breaks up the whole blockchain world and turns the global village back into the city-state tribe of the primitive society. Celare, who proposes the world’s first full-asset cross-chain and anonymous solution, which not only realizes the value transfer between different blockchain networks but also guarantees the privacy security of users.
I. What is Celare?
Before introducing Celare, it’s necessary to share Polkadot — — Polkadot is an exploration of cross-chain technology presented by the co-founder of Ethereum and funder of Parity Technologies, Gavin Wood, on November 14, 2016. Polkadot is a decentralized and scalable heterogeneous multi-chain framework that supports cross-chain communication between different chains, not only for asset exchange and transfer but also for data cross-chain discussion. The Polkadot network has three primary functions that address interoperability, scalability, and shared security issues in the Blockchain. Polkadot is similar to Vodafone, an infrastructure service provider that provides communication bandwidth services between networks. Developers can develop applications based on this infrastructure. Celare, a parallel chain of privacy smart contracts in the Polkadot ecosystem, is developed based on Substrate. By selecting the BLS12–381 curve to achieve zero-knowledge proof, Celare indeed implements the blockchain system with the privacy protection of Turing-complete smart contracts. https://preview.redd.it/2kcvnx9xggn41.png?width=2814&format=png&auto=webp&s=258d53a5787c93b618ab3d53295cc44a76535102 For example, it is like setting up a public tent in the middle of two mutually disjoint parallel roads. People who are tired of walking can enter the tent for a rest. For fear of the security of the money, each person who enters the tent is assigned another invisibility cloak. The public tent is the Polkadot, and Celare is the organizer and guardian of the ecology. It increases the diversity of “road,” bridges the connectivity between different projects, and ensures the privacy of the project and assets safety, better to create ecological consensus. Compared with the existing Blockchain privacy protection technology, Celare not only realizes the privacy protection of account information and transaction but also recognizes the cross-chain ecosystem. https://preview.redd.it/i43nf7qzggn41.png?width=1606&format=png&auto=webp&s=4266de4c99e5df48a3782e4425182b039c7b39ab
II. Celare’s Economic Model
Celare is the basic unit of circulation within the Celare ecosystem. It also represents users and participants in the system and is the only commercial and financial delivery medium within the system. At the beginning of the release, it is compatible with ERC20 and will be switched after the Celare network launch officially. Celare has a constant total of 200 million tokens, 50% of which obtains through Entangled Lockdrop; 40% for the incentive distribution of PoS Staking mechanism; 5% is the essential funding for the community development team and unlock flexibility during four years; The remaining 3% is the reward the community contributors and co-builders. For the early service promotion, 2% will be reserved as an incentive, which will be rewarded by the community decision making, to realize the shared benefits of the ecosystem. Celare Co-founders’ committee convinces that any project cannot be separated from ecological contributors. Everyone in the community enjoys a high degree of freedom, full value realization, and happiness. This is the goal that the Celare Co-Founders’ Committee will fight for. https://preview.redd.it/n50fncv2hgn41.jpg?width=700&format=pjpg&auto=webp&s=5c565df7cb159e2f2cfc7f61a8b822efb951665b

2021.Q1 Celare will continue to support the community in developing various DApps. * Code open source, support smart contracts to issue anonymous assets * Publish client wallet * Multi-party secure computing and privacy protection mechanisms for data under the chain. *Anonymous Asset Exchange *Anonymous chat tool with OTC
When you look back at the development of the Blockchain for ten years, you will find that dreams, especially technical dreams, if realized, will be a good thing for the benefit of humanity. So there will be so many professional geeks going forward bravely to liberating all humans. And Celare’s technical vision is simple: security, privacy, and cross-chain. How to achieve that? Celare ecologically has designed the following ways: 1# All Assets Anonymity In Celare, the data in the ordinary transaction is encrypted, and the non-transaction parties cannot know the details such as source, destination, asset type, and amount. Regardless of the assets, Celare can fully guarantee the privacy and anonymity of assets, and truly realize the anonymity of all assets. 2# Anonymous asset exchange Different from the centralized exchanges with KYC, Celare is a veritable anonymous asset exchange through Polkadot relay cross-chain technology, which fully protects user privacy and asset anonymity. 3# Anonymous chat tool with OTC It is a secure, anonymous channel that breaks the Internet blockade and does not require a VPN, to protect user privacy and security for the entire Celare ecosystem. The so-called anonymity is not only the authentication without personal identity information, but also the hidden high-anonymity Celare of the communication channel uses distributed nodes to support the entire network operation. Not only that, in the process of using covert chat, but no third party stores the message content, and the chat content will also be stored in the local file. The master node is only responsible for providing network transmission and content delivery. Based on anonymous peer-to-peer chat, Celare users and groups in the community can independently launch OTC (over-the-counter transaction). And the transaction information and chat content are entirely secret, without worrying about being supervised or eavesdropped, to protect user privacy and security for the entire Celare ecosystem. https://preview.redd.it/h4un51omhgn41.png?width=2416&format=png&auto=webp&s=b2a0b62a5d309f605c2a724f0e5447397997c3ab 4# Stack extension Celare will be evolved and absorbed in the Celare development process, to realize plenty of the stack ecology applications, such as Parity Substrate, Wasm, DAO, Treasury. Celare will bring together all parachain developers and community to witness the first big fusion in the history of Blockchain. The blockchain is no longer an isolated island, no longer competing for users, and Celare will lead the world’s developers to witness the arrival of the cross-chain era.

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything. The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years. In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.
UPDATED - Groestlcoin Core 2.18.2
This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables. NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.
Builds are now done through Gitian
Calls to getblocktemplate will fail if the segwit rule is not specified. Calling getblocktemplate without segwit specified is almost certainly a misconfiguration since doing so results in lower rewards for the miner. Failed calls will produce an error message describing how to enable the segwit rule.
A warning is printed if an unrecognized section name is used in the configuration file. Recognized sections are [test], [main], and [regtest].
Four new options are available for configuring the maximum number of messages that ZMQ will queue in memory (the "high water mark") before dropping additional messages. The default value is 1,000, the same as was used for previous releases.
The rpcallowip option can no longer be used to automatically listen on all network interfaces. Instead, the rpcbind parameter must be used to specify the IP addresses to listen on. Listening for RPC commands over a public network connection is insecure and should be disabled, so a warning is now printed if a user selects such a configuration. If you need to expose RPC in order to use a tool like Docker, ensure you only bind RPC to your localhost, e.g. docker run [...] -p 127.0.0.1:1441:1441 (this is an extra :1441 over the normal Docker port specification).
The rpcpassword option now causes a startup error if the password set in the configuration file contains a hash character (#), as it's ambiguous whether the hash character is meant for the password or as a comment.
The whitelistforcerelay option is used to relay transactions from whitelisted peers even when not accepted to the mempool. This option now defaults to being off, so that changes in policy and disconnect/ban behavior will not cause a node that is whitelisting another to be dropped by peers.
A new short about the JSON-RPC interface describes cases where the results of anRPC might contain inconsistencies between data sourced from differentsubsystems, such as wallet state and mempool state.
A new document introduces Groestlcoin Core's BIP174 interface, which is used to allow multiple programs to collaboratively work to create, sign, and broadcast new transactions. This is useful for offline (cold storage) wallets, multisig wallets, coinjoin implementations, and many other cases where two or more programs need to interact to generate a complete transaction.
The output script descriptor (https://github.com/groestlcoin/groestlcoin/blob/mastedoc/descriptors.md) documentation has been updated with information about new features in this still-developing language for describing the output scripts that a wallet or other program wants to receive notifications for, such as which addresses it wants to know received payments. The language is currently used in multiple new and updated RPCs described in these release notes and is expected to be adapted to other RPCs and to the underlying wallet structure.
A new --disable-bip70 option may be passed to ./configure to prevent Groestlcoin-Qt from being built with support for the BIP70 payment protocol or from linking libssl. As the payment protocol has exposed Groestlcoin Core to libssl vulnerabilities in the past, builders who don't need BIP70 support are encouraged to use this option to reduce their exposure to future vulnerabilities.
The minimum required version of Qt (when building the GUI) has been increased from 5.2 to 5.5.1 (the depends system provides 5.9.7)
getnodeaddresses returns peer addresses known to this node. It may be used to find nodes to connect to without using a DNS seeder.
listwalletdir returns a list of wallets in the wallet directory (either the default wallet directory or the directory configured bythe -walletdir parameter).
getrpcinfo returns runtime details of the RPC server. Currently, it returns an array of the currently active commands and how long they've been running.
deriveaddresses returns one or more addresses corresponding to an output descriptor.
getdescriptorinfo accepts a descriptor and returns information aboutit, including its computed checksum.
joinpsbts merges multiple distinct PSBTs into a single PSBT. The multiple PSBTs must have different inputs. The resulting PSBT will contain every input and output from all the PSBTs. Any signatures provided in any of the PSBTs will be dropped.
analyzepsbt examines a PSBT and provides information about what the PSBT contains and the next steps that need to be taken in order to complete the transaction. For each input of a PSBT, analyze psbt provides information about what information is missing for that input, including whether a UTXO needs to be provided, what pubkeys still need to be provided, which scripts need to be provided, and what signatures are still needed. Every input will also list which role is needed to complete that input, and analyzepsbt will also list the next role in general needed to complete the PSBT. analyzepsbt will also provide the estimated fee rate and estimated virtual size of the completed transaction if it has enough information to do so.
utxoupdatepsbt searches the set of Unspent Transaction Outputs (UTXOs) to find the outputs being spent by the partial transaction. PSBTs need to have the UTXOs being spent to be provided because the signing algorithm requires information from the UTXO being spent. For segwit inputs, only the UTXO itself is necessary. For non-segwit outputs, the entire previous transaction is needed so that signers can be sure that they are signing the correct thing. Unfortunately, because the UTXO set only contains UTXOs and not full transactions, utxoupdatepsbt will only add the UTXO for segwit inputs.
getpeerinfo now returns an additional minfeefilter field set to the peer's BIP133 fee filter. You can use this to detect that you have peers that are willing to accept transactions below the default minimum relay fee.
The mempool RPCs, such as getrawmempool with verbose=true, now return an additional "bip125-replaceable" value indicating whether thetransaction (or its unconfirmed ancestors) opts-in to asking nodes and miners to replace it with a higher-feerate transaction spending any of the same inputs.
settxfee previously silently ignored attempts to set the fee below the allowed minimums. It now prints a warning. The special value of"0" may still be used to request the minimum value.
getaddressinfo now provides an ischange field indicating whether the wallet used the address in a change output.
importmulti has been updated to support P2WSH, P2WPKH, P2SH-P2WPKH, and P2SH-P2WSH. Requests for P2WSH and P2SH-P2WSH accept an additional witnessscript parameter.
importmulti now returns an additional warnings field for each request with an array of strings explaining when fields are being ignored or are inconsistent, if there are any.
getaddressinfo now returns an additional solvable Boolean field when Groestlcoin Core knows enough about the address's scriptPubKey, optional redeemScript, and optional witnessScript for the wallet to be able to generate an unsigned input spending funds sent to that address.
The getaddressinfo, listunspent, and scantxoutset RPCs now return an additional desc field that contains an output descriptor containing all key paths and signing information for the address (except for the private key). The desc field is only returned for getaddressinfo and listunspent when the address is solvable.
importprivkey will preserve previously-set labels for addresses or public keys corresponding to the private key being imported. For example, if you imported a watch-only address with the label "coldwallet" in earlier releases of Groestlcoin Core, subsequently importing the private key would default to resetting the address's label to the default empty-string label (""). In this release, the previous label of "cold wallet" will be retained. If you optionally specify any label besides the default when calling importprivkey, the new label will be applied to the address.
getmininginfo now omits currentblockweight and currentblocktx when a block was never assembled via RPC on this node.
The getrawtransaction RPC & REST endpoints no longer check the unspent UTXO set for a transaction. The remaining behaviors are as follows:
If a blockhash is provided, check the corresponding block.
If no blockhash is provided, check the mempool.
If no blockhash is provided but txindex is enabled, also check txindex.
unloadwallet is now synchronous, meaning it will not return until the wallet is fully unloaded.
importmulti now supports importing of addresses from descriptors. A desc parameter can be provided instead of the "scriptPubKey" in are quest, as well as an optional range for ranged descriptors to specify the start and end of the range to import. Descriptors with key origin information imported through importmulti will have their key origin information stored in the wallet for use with creating PSBTs.
listunspent has been modified so that it also returns witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output.
createwallet now has an optional blank argument that can be used to create a blank wallet. Blank wallets do not have any keys or HDseed. They cannot be opened in software older than 2.18.2. Once a blank wallet has a HD seed set (by using sethdseed) or private keys, scripts, addresses, and other watch only things have been imported, the wallet is no longer blank and can be opened in 2.17.2. Encrypting a blank wallet will also set a HD seed for it.
signrawtransaction is removed after being deprecated and hidden behind a special configuration option in version 2.17.2.
The 'account' API is removed after being deprecated in v2.17.2 The 'label' API was introduced in v2.17.2 as a replacement for accounts. See the release notes from v2.17.2 for a full description of the changes from the 'account' API to the 'label' API.
addwitnessaddress is removed after being deprecated in version 2.16.0.
generate is deprecated and will be fully removed in a subsequent major version. This RPC is only used for testing, but its implementation reached across multiple subsystems (wallet and mining), so it is being deprecated to simplify the wallet-node interface. Projects that are using generate for testing purposes should transition to using the generatetoaddress RPC, which does not require or use the wallet component. Calling generatetoaddress with an address returned by the getnewaddress RPC gives the same functionality as the old generate RPC. To continue using generate in this version, restart groestlcoind with the -deprecatedrpc=generate configuration option.
Be reminded that parts of the validateaddress command have been deprecated and moved to getaddressinfo. The following deprecated fields have moved to getaddressinfo: ismine, iswatchonly,script, hex, pubkeys, sigsrequired, pubkey, embedded,iscompressed, label, timestamp, hdkeypath, hdmasterkeyid.
The addresses field has been removed from the validateaddressand getaddressinfo RPC methods. This field was confusing since it referred to public keys using their P2PKH address. Clients should use the embedded.address field for P2SH or P2WSH wrapped addresses, and pubkeys for inspecting multisig participants.
A new /rest/blockhashbyheight/ endpoint is added for fetching the hash of the block in the current best blockchain based on its height (how many blocks it is after the Genesis Block).
A new Window menu is added alongside the existing File, Settings, and Help menus. Several items from the other menus that opened new windows have been moved to this new Window menu.
In the Send tab, the checkbox for "pay only the required fee" has been removed. Instead, the user can simply decrease the value in the Custom Fee rate field all the way down to the node's configured minimumrelay fee.
In the Overview tab, the watch-only balance will be the only balance shown if the wallet was created using the createwallet RPC and thedisable_private_keys parameter was set to true.
The launch-on-startup option is no longer available on macOS if compiled with macosx min version greater than 10.11 (useCXXFLAGS="-mmacosx-version-min=10.11" CFLAGS="-mmacosx-version-min=10.11" for setting the deployment sdkversion)
A new groestlcoin-wallet tool is now distributed alongside Groestlcoin Core's other executables. Without needing to use any RPCs, this tool can currently create a new wallet file or display some basic information about an existing wallet, such as whether the wallet is encrypted, whether it uses an HD seed, how many transactions it contains, and how many address book entries it has.
Since version 2.16.0, Groestlcoin Core's built-in wallet has defaulted to generating P2SH-wrapped segwit addresses when users want to receive payments. These addresses are backwards compatible with all widely used software. Starting with Groestlcoin Core 2.20.1 (expected about a year after 2.18.2), Groestlcoin Core will default to native segwitaddresses (bech32) that provide additional fee savings and other benefits. Currently, many wallets and services already support sending to bech32 addresses, and if the Groestlcoin Core project sees enough additional adoption, it will instead default to bech32 receiving addresses in Groestlcoin Core 2.19.1. P2SH-wrapped segwit addresses will continue to be provided if the user requests them in the GUI or by RPC, and anyone who doesn't want the update will be able to configure their default address type. (Similarly, pioneering users who want to change their default now may set the addresstype=bech32 configuration option in any Groestlcoin Core release from 2.16.0 up.)
BIP 61 reject messages are now deprecated. Reject messages have no use case on the P2P network and are only logged for debugging by most network nodes. Furthermore, they increase bandwidth and can be harmful for privacy and security. It has been possible to disable BIP 61 messages since v2.17.2 with the -enablebip61=0 option. BIP 61 messages will be disabled by default in a future version, before being removed entirely.
The submitblock RPC previously returned the reason a rejected block was invalid the first time it processed that block but returned a generic "duplicate" rejection message on subsequent occasions it processed the same block. It now always returns the fundamental reason for rejecting an invalid block and only returns "duplicate" for valid blocks it has already accepted.
A new submitheader RPC allows submitting block headers independently from their block. This is likely only useful for testing.
The signrawtransactionwithkey and signrawtransactionwithwallet RPCs have been modified so that they also optionally accept a witnessScript, the witness script in the case of a P2WSH orP2SH-P2WSH output. This is compatible with the change to listunspent.
For the walletprocesspsbt and walletcreatefundedpsbt RPCs, if thebip32derivs parameter is set to true but the key metadata for a public key has not been updated yet, then that key will have a derivation path as if it were just an independent key (i.e. no derivation path and its master fingerprint is itself).
The -usehd configuration option was removed in version 2.16.0 From that version onwards, all new wallets created are hierarchical deterministic wallets. This release makes specifying -usehd an invalid configuration option.
This release allows peers that your node automatically disconnected for misbehaviour (e.g. sending invalid data) to reconnect to your node if you have unused incoming connection slots. If your slots fill up, a misbehaving node will be disconnected to make room for nodes without a history of problems (unless the misbehaving node helps your node in some other way, such as by connecting to a part of the Internet from which you don't have many other peers). Previously, Groestlcoin Core banned the IP addresses of misbehaving peers for a period (default of 1 day); this was easily circumvented by attackers with multiple IP addresses. If you manually ban a peer, such as by using the setban RPC, all connections from that peer will still be rejected.
The key metadata will need to be upgraded the first time that the HDseed is available. For unencrypted wallets this will occur on wallet loading. For encrypted wallets this will occur the first time the wallet is unlocked.
Newly encrypted wallets will no longer require restarting the software. Instead such wallets will be completely unloaded and reloaded to achieve the same effect.
A sub-project of Bitcoin Core now provides Hardware Wallet Interaction (HWI) scripts that allow command-line users to use several popular hardware key management devices with Groestlcoin Core. See their project page for details.
This release changes the Random Number Generator (RNG) used from OpenSSL to Groestlcoin Core's own implementation, although entropy gathered by Groestlcoin Core is fed out to OpenSSL and then read back in when the program needs strong randomness. This moves Groestlcoin Core a little closer to no longer needing to depend on OpenSSL, a dependency that has caused security issues in the past. The new implementation gathers entropy from multiple sources, including from hardware supporting the rdseed CPU instruction.
On macOS, Groestlcoin Core now opts out of application CPU throttling ("app nap") during initial blockchain download, when catching up from over 100 blocks behind the current chain tip, or when reindexing chain data. This helps prevent these operations from taking an excessively long time because the operating system is attempting to conserve power.
How to Upgrade?
Windows If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), then run the installer. OSX If you are running an older version, shut it down. Wait until it has completely shut down (which might take a few minutes for older versions), run the dmg and drag Groestlcoin Core to Applications. Ubuntu http://groestlcoin.org/forum/index.php?topic=441.0
ALL NEW - Groestlcoin Moonshine iOS/Android Wallet
Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network. GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.
Groestlcoin Mainnet & Testnet supported
Multiple wallet support
Electrum - Support for both random and custom peers
Biometric + Pin authentication
Custom fee selection
Import mnemonic phrases via manual entry or scanning
BIP39 Passphrase functionality
Support for Segwit-compatible & legacy addresses in settings
Support individual private key sweeping
UTXO blacklisting - Accessible via the Transaction Detail view, this allows users to blacklist any utxo that they do not wish to include in their list of available utxo's when sending transactions. Blacklisting a utxo excludes its amount from the wallet's total balance.
Ability to Sign & Verify Messages
Support BitID for password-free authentication
Coin Control - This can be accessed from the Send Transaction view and basically allows users to select from a list of available UTXO's to include in their transaction.
HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled. HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user. Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.
Simplified payment verification for fast mobile performance
Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases. This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats. To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.
If a word is wrong, the tool will try to suggest the closest option.
If a word is missing or unknown, please type "?" instead and the tool will find all relevant options.
NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator. VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline. If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address. VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase. VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).
Fixed size arithmetic
Fast Modular Inversion (Delayed Right Shift 62 bits)
SecpK1 Fast modular multiplication (2 steps folding 512bits to 256bits using 64 bits digits)
Use some properties of elliptic curve to generate more keys
SSE Secure Hash Algorithm SHA256 and RIPEMD160 (CPU)
Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet. If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).
Ability to continue finding keys after first one is found
Includes warning on start-up if connected to the internet
Ability to output keys to a text file (And shows button to open that directory)
Show and hide the private key with a simple toggle switch
Show full output of commands
Ability to choose between Processor (CPU) and Graphics Card (GPU) ( NVidia ONLY! )
Features both a Light and Dark Material Design-Style Themes
Free software - MIT. Anyone can audit the code.
Written in C# - The code is short, and easy to review.
Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode. This wallet was previously deprecated but has been brought back to life with modern standards.
Works via TOR or SOCKS5 proxy
Can use bootstrap.dat format as blockchain database
Import/Export blockchain to/from bootstrap.dat
Import wallet.dat from Groestlcoin-qt wallet
Export wallet to wallet.dat
Use both groestlcoin-wpf and groestlcoin-qt with the same addresses in parallel. When you send money from one program, the transaction will automatically be visible on the other wallet.
Rescan blockchain with a simple mouse click
Works as a full node and listens to port 1331 (listening port can be changed)
Fast Block verifying, parallel processing on multi-core CPUs
Mine Groestlcoins with your CPU by a simple mouse click
All private keys are kept encrypted on your local machine (or on a USB stick)
Lite - Has a lightweight "thin client" mode which does not require a new user to download the entire Groestlcoin chain and store it
Free and decentralised - Open Source under GNU license
Fixed Import/Export to wallet.dat
Rescan wallet option
Change wallet password option
Address type and Change type options through *.conf file
Import from bootstrap.dat - It is a flat, binary file containing Groestlcoin blockchain data, from the genesis block through a recent height. All versions automatically validate and import the file "grs.bootstrap.dat" in the GRS directory. Grs.bootstrap.dat is compatible with Qt wallet. GroestlCoin-Qt can load from it.
In Full mode file %APPDATA%\Groestlcoin-WPF\GRS\GRS.bootstrap.dat is full blockchain in standard bootstrap.dat format and can be used with other clients.
Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node. It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node. Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine. Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in. Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet. Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.
Use your own node
Uses less CPU and RAM than ElectrumX
Used intermittently rather than needing to be always-on
Doesn't require an index of every Groestlcoin address ever used like on ElectrumX
UPDATED – Android Wallet 7.38.1 - Main Net + Test Net
The app allows you to send and receive Groestlcoin on your device using QR codes and URI links. When using this app, please back up your wallet and email them to yourself! This will save your wallet in a password protected file. Then your coins can be retrieved even if you lose your phone.
Add confidence messages, helping users to understand the confidence state of their payments.
Handle edge case when restoring via an external app.
Count devices with a memory class of 128 MB as low ram.
Introduce dark mode on Android 10 devices.
Reduce memory usage of PIN-protected wallets.
Tapping on the app's version will reveal a checksum of the APK that was installed.
Fix issue with confirmation of transactions that empty your wallet.
Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets). Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet. Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.
I'm Giving Away 0.5BTC to Whoever Finds My Lost Electrum Password
A little over a year ago, on 10/22/2016, the price of bitcoin was going up, and the size of the blockchain was growing like crazy, so I decided to transfer a 10.511 BTC wallet I had on a thumb drive from a Bitcoin Core wallet to Electrum (I knew I soon wouldn't have enough space on my HDD for the entire blockchain, which Core requires.) So I fired up Electrum, copied down the addresses, and transferred all 10.511 BTC. One minute later, my heart sank, and I realized what a complete moron I was - this was a wallet I had setup when i first installed Electrum a year earlier, and I had NO IDEA what the password or seed words were. So now I have 10.511 BTC stuck in an Electrum 2.8.3 (EDIT - I see 2.8.3 now, but that didn't even exist on 8/4/2015, so I must've upgraded at some point - SEE BELOW) wallet that I have no access to whatsoever. I've heard that there are people on bitcoin with cracking capabilities, so I wanted to give the community a shot. Here's how this will work. I've extracted partial-MPK data from the extract script I received from btcrecover, a popular password recovery program. With this, you can check passwords. Whoever posts or pm's me the correct password first (along with their receiving address) will receive 0.5 BTC from the following address - 1EoKwutew3rfmKbsNcmi53qMRe84v2Cj4H (one of the five addresses in this wallet that makes up the total 10.511 BTC) Electrum2 partial encrypted master private key, iv, and crc in base64: For use in btcrecover:
This was a "stupid password" that I made mainly just to get through the prompts so I could start exploring the program. It wasn't meant to be super complex. Other passwords i made around that time were "testtesttest" and "electrumpw", so it could be something stupid like that (this electrum wallet was created on 8/4/2015)
It is a password that, when typed into the btcrecover password box in the new wallet creation wizard, shows "Strong" or "Very Strong" in the complexity-indicator, directly below the password box (I wouldn't create a password if it said "weak" or "medium".)
I've already checked all passwords 7 characters or less, so its at least 8 characters. If i had to guess, I'd say its probably 8-16 characters max.
I almost never use capital letters.
I likely added something to the end of the lowercase a-z password to increase complexity. Here's a list of what I commonly add to the ends of passwords: 15 l;' ';l[po 1! !1
Or any of the following 6 characters:
1 ! ` ~ ' (backslash - reddit won't display it)
So those are about all the clues I have. I recommend someone trying a dictionary attack first, and then brute-forcing it. I promise, promise promise I will deliver 0.5BTC to whoever finds the password. I'm recovering 10BTC on top of that, so 0.5BTC is a reasonable price to pay for my idiotic mistake. Good luck, and Happy Holidays! . . . Edit: I will check back every few hours and try all the passwords posted - please don't take random guesses... use btcrecover or John The Ripper to find the actual password using the partial encrypted master private key, iv, and crc in base64 that I posted above (I have to check all these, after all...) Edit 2: Tried all the passwords posted in this thread until 1:34am EST. Going to bed for now, but will check back in the morning. EDIT 3: Some people are pointing out that the version doesn't make any sense, since 2.8.3 didn't exist when I created the wallet. You're, right, this version came out in 2017. I am sorry I got this wrong - I've been looking at Electrum 2.8.3 for the past year or so, as I've been trying to open this thing, so I assumed that was it, but its not. All I know is, I downloaded Electrum for the first time on this computer on 8/4/2015 at around 4am EST. Does anyone know what version that is? If its 1.X, PLEASE tell me so I can update the partial encrypted master private key above, as the one above I used an extract script for 2.X!!! EDIT 4: I'm 99% certain you will find the password if you brute force lowercase letters a-z, after removing some "non-interesting" letters like z,q, etc. Its just about which letters to guess. The ONLY numbers that could POSSIBLY be at the end are "15". So either it ends in 15 or it doesn't, there's no way I'd use any other numbers. So please, whoever has access to a large bank of CPU's, PLEASE try using btcrecover (or better yet, JTR) to try a-z, minus some less-popular characters. Possibly the letters ""a b c d e f i k l m n o r s t w y", but I could be missing some. Also, PLEASE POST YOUR BITCOIN ADDRESS ALONG WITH YOUR ANSWER! I will send you coins from 1EoKwutew3rfmKbsNcmi53qMRe84v2Cj4H, one of the addresses in the locked wallet. Finally, I just want to be clear - I will give the 0.5 BTC reward to whoever helps me open this wallet - whether they figured out some crazy technical workaround, find the password itself, or gave me hints that allowed me to discover the password myself, whoever helps me unlock these funds first will be rewarded. EDIT 5: Some people are curious as to whether this is indeed my wallet. Yes, it is: the first 0.1BTC I sent to the wallet on 8/4/2015 was sent directly to this wallet from my Coinbase account. Proof: https://imgur.com/a/zsjZw EDIT 6 - MAKING PROGRESS BABY! If you're using btcrecover, please put this in your token file:
Add as many lines as you think there are digits (probably 9-12), remembering to change the number of the line in the beginning, and change the group of letters that you think might be included in the pw. THE LESS LETTERS YOU INCLUDE, THE GREATER THE LENGTH YOU CAN CHECK. Please remember to add the tags "--no-eta" and "--no-dupchecks" so you don't run out of memory. Unfortunately my machine can only do 600kP/s, so I can't find it myself, but someone with access to a lot of servers can probably find the password very quickly!!! EDIT 7 - Making a bit of progress, very very slowly. Here's an important clue: when I created this wallet, which, remember, was the very first Electrum wallet I ever created, I would have made sure to add enough complexity so that the complexity meter below the password input box says "Strong". I would've never clicked Continue if the complexity-indicator said I "Weak" or "Medium". So if there's some way to ignore ALL "Weak" or "Medium" passwords, that could speed up the search significantly. It looks like if you use just lowercase a-z, when you add a single "!" at the end for increased complexity, the minimum total characters that gets you a "Strong" password is 12 ((a-z)x11 + "!"). Nobody's been searching for this quite yet, because 11 characters is a lot, and it could be more. The only way I see this happening is if you do a hybrid dictionary+brute force attack, of if you substantially cut down on the number of letters tested by eliminating "uninteresting" letters like q, z, v, x, etc. Based on everything, I think the total is at least 12 characters, but no more than 16, and contains a special character at the end (such as !, 1, ~, (~ if you don't hold shift, reddit won't display it), ', or \ - these are the 6 special characters I usually use by themselves at the end of a password - ' and \ because they're right next to Enter on a standard US keyboard, and ! or 1 (or !1 or 1! together) or ` or ~ because they're my go-to's). I've also looked through my photo archive from that time period and found a DIFFERENT seed for a wallet I made on Aug. 18th, 2015 (crunch sunny range evoke rapid use bubble gloom pill gossip blanket tired accident - there's about 3 bucks in there for whoever wants it). The password for this wallet was originally "testtesttest". EDIT 8 - Still no password as of 12/12/2017, and this will be my last edit. If you find the password, PM me. EDIT 9 - I will update this page as soon as the password is found. If you are seeing this message, it means the password has not yet been found.
First off I'll start off by saying I truly believe this show to be a case of "the plot doesn't matter", it serves rather, as an engine that fuels exploration into bigger picture stuff -- commentary on capitalism, a mirror to examine our own emotion as shown through character's reactions to events. So if I'm way off base here it doesn't matter and if i'm spot on it doesn't matter. Nonetheless, I'm going to attempt and present what may serve as a means of "understanding" the why of the season finale. The cosmic error we were informed of this season, twins, is also seen in computers, these technically are called soft errors, but they are sometimes caused by cosmic rays. Essentially, cosmic rays have a statistically significant chance to change a piece of data stored in memory. This change in data has the power to change the way a system runs if not checked and corrected but does not imply it has affected it or will whether or not it is caught or if that data can not be recovered. Twins present a "cosmic error" because where one sperm enters, two babies leave. The race condition of millions of sperm trying to fertilize an egg is solved by simply allowing only one sperm to do so (most of the time, maybe it happens, idk). But that doesn't stop a random split from happening that can potentially put the mom's life at greater risk of failing to give birth by doubling the load. Concurrency in computer programming is where two processes are able to run simultaneously. A race condition is made when those two processes enter a critical part of their execution at the same time, that is to say try to access the same piece of data from memory at the same time. Put simply, if you and friend each opened a cupboard, checked how many apples were stored, add a number of apples, each exclusively, and mark down how many should now be in the cupboard you both should know how many are in the cupboard right? Nope. If there's one in the cupboard and you add two, you've marked down that there are 3 apples in the cupboard. However, your friend has decided to put one and did it before you put yours back. Now you and your friend both don't know how many apples are in the cupboard, as he thinks there are two when both of you are wrong -- there's four. So the next time you both go back to check your data is completely unreliable and subsequent calculations will compound how incorrect you are. Even if you both end up with the correct number at the end, it's a fluke and more still missing the error. This only makes sense if you take a literal blind approach in which is you only can see what was stored once when opening it and cannot double check what was written down, you have to trust what was stored after opening as it should match what's written down. The answer in programming can't always be store it twice in memory (here memory means random access, not disk stored). One way of solving this is through the implementation of mutual exclusion, also called a mutex. The simplest example of a mutex, both actually and in our example is putting a lock on the cupboard with a single key you must use to unlock when checking, lock while adding apples, and then give up so your friend might access the cupboard. This ensures that you both have the right data each time you check. I'm skipping over some stuff because the piece that's important is that only one can be inside at any given time. Semaphores are another way of achieving this, but instead of using a key a system of counting is put into place. this is done by knowing how many of a given resource are available at any given time and recording it. Currency, often believed to be rooted in a gold standard, uses this system to account for inflation or whatever. Funny enough bitcoin actually IS founded on a gold standard. One that so far can not be manipulated. Alchemy presents a logical problem for this, since gold cannot be created through chemistry and thus there is a finite amount of it. Same way there is a finite amount of bitcoin that will ever enter circulation. Today, gold is still thought of as valuable. It's brought up early on in the series by Dud that the more gold that exists the less special it is, and thus would lose its value. One of the most historically valuable properties of gold is its malleability, and prettyness which allowed for more ornate objects of beauty to be crafted without the need for advanced smelting and casting. Today that is of much less concern. Silver, on the other hand, in today's modern age, has the advantage of being the most electrically conductive metal we know about. Second comes copper and in third is gold. Guess which one we use most often in circuitry and in wiring buildings. Conductivity is literally based on the Silver standard. While in many ways Dud may be seen as inferior to Liz, intelligence wise, money wise -- double down on a bad interest loan by paying it off with a worse interest loan vs. paying it off slowly and painfully, etc. He is often seen to be coming out ahead in terms of sheer happiness and fortitude where Liz cannot. If one sperm in a race produced two non identical babies, neither inherently came in first from the get go. As I said above, neither metal, gold or silver, wins in terms of actual utility in the conductivity battle. However, Dud enters the lodge first, and gets struck by lightning. Given the information we are given in the first season we are not made privy to a lot of things that become important. Primarily, that the scrolls might be the solution to cracking bitcoin and thus disrupting its backed worth based on the gold standard. So, here, the "cosmic error" of twins and the challenge it presents in this concurrent system is brought into the main stage. Liz and Dud are both on a quest but neither really knows what or why. Both survive extreme conditions they are put in both voluntarily and involuntarily respectively. This all changes when Liz enters the Lodge. Up until this point Liz has not entered the lodge out of her own "choice", free will arguments here be damned. She doesn't go in because she doesn't care. It takes Dud not answering her texts for her to enter and when she does so the Lodge corrects for it. If detected, a soft error may be totally recovered from, but if the system has crashed, the computer needs to be "rebooted" before any data correction can occur. If they were both in the Lodge at the same time due to a cosmic error which, in terms of my example above, changes the number of apples in the cupboard while it's locked or changes the total number of apples available. If they weren't physically in the Lodge at the same time holds no bearing, it's that they were a part of the lodge. As long as Liz is accessing the Lodge Dud cannot. While humans allegedly built the Lodge, it is impossibly complex to the point where it has literal doors it can throw you backwards out of, possibly as a way of rebirth and possibly as a way of creating a "plant". Liz just as easily could have not been kept on her feet had her friends not been there the same way Duds was from his near death experiences, however they were there. For a door that opens out, and that no one knows how to access, it sure as shit is not protected from the obvious safety-precaution; securing it from being opened from the outside. Maybe it has been attempted but it just always fell down. But when the light next to the door is being repaired for safety reasons it's not like anyone says hey if we don't know where this door leads and idk, maybe we have some voluntarily blind girl living and running around fixing her seizure problems like, let's maybe just take care of fix this other hazard. Brute force is used to open doors all over the place in the show, even as far as being used as a "lockpick" (axe), but is never used to unlock THAT door, at least successfully or on screen. Maybe it can't be bruteforced the same way brute force can't be used to cheat bitcoin (it can't, at least today). Quantum computing poses a very real threat to this, and actually every "lock" we think is secure. Like, won't get into it too much and it's not this simple but imagine just asking the computer what your neighbors wifi password is and it just gives you the answer without having to try an approaching infinite number of possible solutions. A very real threat to bitcoin and as a matter of fact all modern encryption, however to scare you less if we're smart enough to pull it off we're at least smart enough to solve the problem before we get there (i've been assured by our friends at google that their contingency plans can't fail, they also told me the titanic never sank) This at least approaches an explanation to the apparent deus ex machina that is Dud's death. The Lodge is not a joke, and has real control of things. While running it exposes powerful implications into the lives of its members and those around them. I think it's clear here that the duty of the knights of the lodge, to protect it, has greater meaning than we know. To this same affect, we see another parallel for modern networked computing to work reliably -- redundancy. One man cannot keep the Lodge alive himself, nor can dwindling numbers of protectors. So make more of them, and why not spread them out so if an entire area is affected by say 10 hurricanes at once, it doesn't take down the whole lodge and working knowledge of things. Redundancy in computing means basically the same thing, keep servers in more than one place and have the data they serve backed up and available in more than one place. This also mitigates the probability of data loss, though not entirely. As the lodge in London had no idea the scrolls were removed and the xeroxes made may have gone the way of Orbis, and potentially only one copy of until they were recovered in Mexico. So far, my only intention has been to make parallels that may have not been made so excuse me while I hurl myself over the side of the boat and bring this to my conclusion on what to make of all this. Skip ahead 2 paragraphs to ignore it. Simulation Theory. As the always headstrong u/L_Marvin_Metz says so poignantly says "the earth is hollow". While, maybe meant to be taken at face value, it probably isn't. But figuratively speaking, definitely. So many of life's pursuits are hollow and we often see characters in the show being punished for these impure pursuits. What else could allow for impossible tunnels, resurrection, portals and magic? A lot of things but nonetheless, Simulation theory would also give a lot for credence to all the talk about "getting out", a reason why Liz and Dud can't be in the Lodge at the same time beyond some deus ex machina. Liz needs a reason to figure out the system and for her it's finding her brother. Whether or not she can (probably can't, if he is rebooted/born again why would that be up to us). Or that's what I'm going to postulate for season 3. Either way the scrolls are there because of reasons no one intended, and all that talk about destiny and painting the future but not getting to actually make it up begin to make sense. The lodge will fulfill its purpose because it already has. The absurdity of simulation theory requires the possibility of multiple layers of simulation, as above and so too is below, also begins to make sense in this context. This could literally go anywhere so I'm gonna stop at this point. Dud is dead, for now in a sense. However, that's if him crashing out of that door covered in dirt wasn't just him falling out in the same sequence we observer it. There may have been for a way less complex reason than I am making - that being actor availability and the inability to pay the highly in-demand Wyatt Russell both for opportunity cost on a show with a future unknown and for his actual need to have a minimum price that the show may not be able to pay. However limited his role is has yet to be seen, and hopefully for the sake of everything will be seen next year, but we saw him get an emmy nomination in the finale -- at least I truly believe that (specifically when he denied the knighthood). But it could be from any episode this season probably. If he takes home the gold who knows what that extra prestige will do to any budgetary restraints on AMC's wallet in the future. Clearly he likes being in this show, so I see know reason why he wouldn't return as a lead if i'm at all correct about any of this. Point of this being that we have no idea if any of this is intentional, if it was written in due to the unknown future of the show even after being renewed last year, always the plan, or not even touching on the plan. That's why deus ex machina can be both brilliant and convenient (Adaptation). If you execute it well, we, as an audience, can't say for certain how it entered the arena. I mean, specifically as a season finale. Plenty of other examples of it in the show, obviously. almost like it's part of a greater theme?

Where can you use NAV?
Introduction - What is NavCoin?
NavCoin is a cryptocurrency that has been publicly traded since mid 2014. It's a fork of the latest version of Bitcoin Core with many additional features and functionalities which differentiate NAV from other cryptos.
NavCoin has been one of the first projects to switch to Proof of Stake and is still using PoS to validate and generate blocks. NavCoin didn't have an ICO or a premine. It is self-funded from the beginning and primarily, but not solely maintained by developers of Encrypt-S - the NavCoin Core team (see below for more info about the team).
NAV is trying to simplify cryptocurrencies for the masses. It does this by providing features which make it easy to use like the implementation of OpenAlias, which allows people to send NAV to an email-like address (for example [[email protected]](mailto:[email protected])). It also provides very easy to use desktop and mobile wallets.
NAV also provides optional privacy. You can send transactions publicly or private, as you prefer.
It's block speed is really fast with about 30 seconds per block. Transactions are confirmed as spendable within only 30 second which makes it ideal for retail and e-commerce.
High levels of scalability (260+ transactions per second)
It currently has a market cap of 11.6kk (as of writing) and trades for about $0.18 / 4'872 Sats per NAV. The circulating supply is 64kk with no max supply (with an inflation of about 4%).
Staking NavCoin currently yields about 8–10% of your holdings per year. This number depends on how many NAV are currently staking. The minimum return is about 4% (if every single NAV would be staking).
NAV is available on many different exchanges with the biggest ones being Binance, Bittrex and Poloniex.
Introduction The following chapter will summarize and break down the history of NavCoin in a few sentences. NAV started a long time ago, went through rebrandings and changes of the core team before it became what it is today. SummerCoin NavCoin was initially first introduced under the name SummerCoin on April 23 in 2014. SummerCoin was a fork of the Bitcoin blockchain. It used to have a PoW/PoS hybrid algorithm with a block time of 45 seconds. SummerCoinV2 /NavajoCoin Soon after the initial launch of SummerCoin, the original developer left and SoopY (soopy452000 on bitcointalk) took over as the main developer and rebranded the project to SummerCoinV2 respectively NavajoCoin and introduced new features. The name NavajoCoin was chosen in honor of the Navajo Code Talker. The unbreakable Navajo code was used to encrypt highly classified military information and commands and decrypt the same in WW II. SoopY introduced a technology which allowed sending transactions anonymously and private. This technology was called "Navajo Anonymous Technology". SoopY also released a new wallet and set the Proof of Stake rewards at 10% for the first year, 5% for the second year and 2% for every year after. NavCoin On August 12, 2014, Craig (current lead core developer, pakage on bitcointalk) started to get involved with NAV by helping to set up a website . It was officially announced that Craig joined the core team as a "Wallet & Web Developer" on November 06, 2014. The last tokenswap and restart of the blockchain of NAV happened on May 12, 2016. Soon later, SoopY stopped showing up and Craig stepped into the role of the lead core developer. Since then, Craig has assembled a strong team with which he built NavCoin into what it is today. Currently, Craig and the NavCoin Core team is located in New Zealand and they are actively developing many ground-braking features which differentiate NAV from other cryptocurrencies. You will read more about that later in this article.
The Current State
Introduction The year 2018 has been a thriving year for the NavCoin ecosystem. Despite the USD price of NAV not reflecting it, in 2018 the core team has developed a whole bunch of new features. Also the core content creators published the first official guidelines that function as an orientation guide for community content creators. This chapter will give you an overview of the current team, the features, the prior mentioned guidelines and the community of NavCoin. Core Team  Last year, the core team has grown alot. It contains of developers, content creators and interns. The core team are employees of Encrypt S, the New Zealand's leading blockchain R&D lab. Encrypt S is developing blockchain solutions since 2014 and values building open-source software highly. Craig MacGregor - Chief Executive Officer Craig is the CEO of Encrypt S and the founder of NavCoin. He is one of the world's most experienced blockchain developers. Craig founded NavCoin in 2014 and is developing software for it since then. He has assembled a strong team of like-minded people. Craig also speaks at seminars and conferenced. Some of the companies and conferences he did blockchain education sessions at are Oracle, Xero, Air New Zealand, Blok Tex and trademe. Together with the team, he is also doing a education series on YouTube where he explains upcoming features in-depth for the community. Alex Vazquez - Chief Technical Officer Alex is the CTO of Encrypt S and the most active contributor to the NavCoin core Github. He has incredible knowledge of blockchains and proposes and implements solutions for challenges and features. He supports community developers frequently and answers any questions of the community thoroughly. Like Craig, Alex is developing software for the NavCoin ecosystem for a very long time. Alex speaks at universities at times and educates students about the blockchain technology. Paul Sanderson - Lead Software Engineer Paul is the Lead Software Engineer at Encrypt S. He has a flair for technology. His technical and management skills are perfectly suited for consultancy and investment advising. He also frequently contributes to the NavCoin core source code. Rowan Savage - Senior Software Engineer Rowan is a full stack software engineer with more than a decade experience in developing complex front-end web applications. He joined Encrypt S in February 2018 and has since been involved in the Valence Plattform, the Kauri Wallet and NavCoin Core. You will read more about these feature/projects later. Carter Xiao - Lead UX/UI Designer Carter specializes in user-centric design and is also very talented with 3D animation, motion graphics and programming. One of NavCoins core principle is "Simplifying Crypto" and UX/UI is a very important part of that. Matt Paul - Software Engineer Like Rowan, Matt is a full stack Software Engineer. He joined the core team in Mai 2017 and has since worked on NavPay, NavPi, the Kauri Wallet and NavCoin Core. Kieren Hyland - Chief Strategy Officer Kieren is one of the employees that are working for Encrypt S for a very long time. He is the CSO and is a digital strategist and growth hacker with a passion for new technology and has a lot of experience in online marketing. Laura Harris - Creative Director Laura has a combination of commercial and creative flair. She manages the social media accounts for NavCoin and ensures, that NavCoins' message is always powerful, relevant and distinctive. John Darby - Content Creator John is an internationally awarded Technology and Financial sector marketing communications specialist. He is one of the Core Content Creators for NavCoin. Features of NavCoin  The following features are currently available and have been developed in the last months and years. It is sorted from newest to oldest. Static Block Reward The soft-fork for the enabling of static block rewards have been accepted and became active recently at 5th January 2019. This means, that the block reward was changed from a percentage based reward to a static reward. This will incentivize the stakers to have their node online 24/7 which increased the security of the network. It also aligns NavCoin with the PoSv3 specification. With this implementation, the yearly inflation will be 3.6% currently and will exponentionally decrease because of the static value of the rewards. Every staked block will now give the staker 2 NAV. Depending on how many people are staking, the yearly percentage varies. With the network weight currently being around 20'000'000 NAV, stakers earn around 10% rewards from staking 24/7. Cold staking To provide extra security to participants in the staking process in the NavCoin network, the core team decided to implement cold staking. This allows to store NAV offline and still be able to sign staking inputs. Looking forward, a possible integration into the Ledger Nano S would mean, that one can stake NAV securely from a offline hardware wallet. How cool is that? OpenAlias One of the core principle of NAV is to simplify cryptocurrencies. Many non-technical people are deterred from the long, cryptic addresses used in wallets. When sending funds, you have to make sure that every single letter and digit is correct which is nerve-wracking for the average person. NavCoin has implemented OpenAlias, which allows to transform the wallet address into a email-like form. Everyone can register a name like "[[email protected]](mailto:[email protected])". Funds can then be sent to this name, which makes sending crypto much easier and less error-prone. Community Fund This is the one big feature I was most excited about. NavCoin core has implemented the first fully decentralized community fund. Acceptance of proposals and release of funds is all approved by the decentralized network. No central authority has access to the fund. The community fund enables everyone to propose their ideas to the NavCoin community and to get paid to implement these ideas. Everyone can propose whatever they like (of course there is a higher rate of success if the proposal contributes to the NavCoin ecosystem ;-)). In fact, this article was sponsored by the NAV-Community by voting "yes" for my proposal. The fund works like this: For a fee of 50 NAV, everyone can create and present his idea/proposal to the entire NavCoin network. The fee is here to help prevent spam attacks. Proposals can literally be anything - be it development, marketing or anything else you can some up with. After creating the proposal, everyone contributing to the NavCoin network can then decide if they like the proposal of not. They vote with "Yes" or "No" for the acceptance of the proposal. Voting happens via staking. Every transaction that gets validated by you gives you one vote. This means that the more NAV you are staking, the higher your voting weight is. The proposal stays in the state "Pending" until it is accepted or rejected. To be accepted, a proposal has to have a participation of at least 50% of all staked blocks and at least 75% of these votes have to be "Yes"-votes. Like-wise to be rejected a proposal need 50% participation of the network and 75% of these votes have to be "No"-votes. Additionally, if a proposal didn't pass after 6 voting cycles (about 6 weeks) it is also rejected. After a proposal has been accepted, the creator of the proposal can start his work. When the work is finished, or at in the proposal defined checkpoints, the proposal creator can create a payment request for the full or part of the requested funds. The NavCoin network can then again decide, if the work is what the creator promised to do and vote for the funds or reject the payment request because it was not what he promised. This mechanism ensures, that the funds are only release if the creator of the proposal did what he promised. The NavCoin network decides everything, there is no central authority which makes the community fund 100% decentralized. The community fund is quite new but there have already been some proposals that were accepted like paying for the development & hosting of NAV block explorer, the creation and distribution of NAV car stickers to the community for free (or paid by the community fund), the funding of interns for NavCoin Core, translation of the website into other languages and YouTube videos. What ideas could you come up with? By the way: this article was also sponsored by the community fund :-) Proof of Stake Like said before, NavCoin uses the Proof of Stake algorithm to create and validate blocks. Participants of the NavCoin network can earn rewards by putting their coins to stake and thus validating blocks and securing the network. The reward used to be 4% fixed but recently changed with the implementation of PoSv3. Currently, rewards for stakers that are staking 24/7 is about 10% but it is dependent on how many people are staking. If more nodes come online, this reward will go down. If 90% of all NAVs would be at stake, stakers would still earn 4%. Tutorials And Guidelines  The NavCoin Core team pushes the community to contribute to the NavCoin ecosystem constantly. They emphasize that NavCoin is an open source project and everyone can contribute. The team tries to make it as easy as possible for the average person to contribute and thus created different tutorials and guidelines. Tutorials To Contribute To The Website The whole website is open source. Everyone can contribute to the website. The team created different guides for people to follow . The NavCoin Developer Manifesto The content creator core team has build a developer manifesto. It defines the values that should be uphold like for example that they will always operate in the best interest of the network. If defines the principles, purposes, scope of involvement and operational requirements . The NavCoin Content Creation Manifesto Similar to the developer manifesto, there is also a content creation manifesto. Again it defines the principles for creating content, the purpose, the scope of involvement and the operational requirements . NavCoin Brand Guidelines In addition to the content creation manifesto, there is also a brand guideline booklet. This should help content creators to create images, videos, articles etc. in the same style as the core team. It defines the NAV brand. The brand guidelines contain definitions, the language to use (words to use, words not to use), the tone of voice, what the community aspires to be and what we discourage to be. It also contains the logo pack which can be used in graphics etc. It describes correct logo spacing, logo placement, the colors of NAV and different web assets. It gives tips about gradients and overlays, the typefaces (with a font pack) and many more. Check it out yourself . NavCoin Educational Series The core team has decided to actively involve the community in the creation of new features. For this reason and to allow users to ask questions, they created the NavCoin Educational Series. The core team schedules an online live meetup which can be joined by everyone. On YouTube they do live-streams and explain upcoming features. Examples of these series are explanations for cold staking, static rewards (PoSv3) and the community fund. The community can ask questions live and the core team will answer them immediately. Community During the last year there have been an influx of software developers from the community starting to create features for NAV. navexplorer.com An examples is navexplorer.com which is programmed by community developer prodpeak and is a block explorer for NavCoin. Additionally, it functions as a interface to see what is going on in the community fund. It shows pending proposals and payment requests. NEXT Wallet The NEXT Wallet is an alternative wallet for NAV and other cryptocurrencies. It has a beautiful user interface and is additionally the easiest interface to interact with the community fund (create proposals, create payment requests and vote for proposals and payment requests). It is programmed by community developer sakdeniz who put hundreds of hours into it during last year. There were also some marketing activities starting to emerge with the release of the community fund. Some of these were for example free stickers for everyone in the NAV community to stick to their car / shop / window etc. or YouTube videos of CryptoCandor and Cryptomoonie that explained the details of NAV. I am sure, that with the 500'000 NAV available in the community fund per year there will be an influx of gread ideas - development as well as marketing activities - that will be funded.
Introduction These features are planned for the future. Many of the following features are part of the 2019 roadmap. Some will not be described in great detail because not much is known about them yet. I've still listed them as they are part of what is yet to come. Features Rimu - Improved Privacy Solution NavCoin used to be a optional privacy coin. That means, that you could choose to send a transaction in private. NavCoin was criticized for the way it handles private payments because it relied on a few servers which didn't make it that decentralized. The technology was called "NavTech" and was a secondary blockchain that obscured the transaction and the amount that was sent. NavCoin Core is currently developing a new improved privacy solution that will make the private payment system completely trustless and districuted and runs at a protocol level. Alex of the NavCoin Core team has published a paper that describes this new privacy solution. It's called Zero Confidential Transactions and can be found here: https://www.researchgate.net/publication/330366788_ZeroCT_Improving_Zerocoin_with_Confidential_Transactions_and_more. What I want to highlight is the collaboration between Alex as the proposer of the solution and the Veil team, a Bitcoin Core developer and Moneros main cryptographer as reviewers. When the best work together, it will be interesting to see what the outcome is! Valence Plattform  Valence is an applied Blockchain platform that can help businesses realise the tangible benefits of blockchain. You can think of Valence as a platform with which you can build Anonymous Distributed Applications (aDapps) with. But Valence is a different kind of platform that enables developers to create new types of blockchain applications. The problem with current (turing complete) dApp platforms are their complexity and rigid nature. Security holes in smart contracts and scaling issues happen frequently . Valence provides transitional pathways that let businesses migrate only part of their activities to the blockchain without having to restructure their entire business model .
Valence will provide a spectrum of blockchain application solutions which sit along the decentralized spectrum, offering businesses simple ways to dip their toes into the blockchain at minimal risk or complexity .
Thanks to the proof of stake nature of the Valence blockchain, more of a node's resources can be used for processing and routing application data which makes the platform faster and scalable.
Valence aims to make building blockchain applications as accessible to the general public as WordPress or Squarespace has made building websites.
The developers NavCoin and Valence aim to make Valence extremely easy to work with:
A Valence application could be an open source mobile or web application that submits unencrypted or encrypted data directly to the blockchain. The only configuration necessary for the app developer would be setting up the data structure. Once they've done that they can start writing to the blockchain immediately. The Valence blockchain interface is language agnostic, meaning developers are free to build applications in whichever language they're familiar with, which greatly reduces the barrier to entry. As the platform progresses, Valence will introduce more and more smart contract templates in collaboration with the development community. These will be like plugins that users can simply select and configure for their application, without having to reinvent the wheel and risk contract errors or spend countless hours of research to program them.
NavShopper The following information is taken from the latest weekly news: NavShopper is a new project which will allow people to spend NavCoin on a growing list of retailers and service providers. NavShopper sits between traditional retailers accepting fiat and NavCoin users and purchases products on behalf of the user by managing the crypt-fiat conversion, payment and shipping. This project will unlock many more ways for people to spend NAV on existing websites/marketplaces without requiring each site to individually accept cryptocurrencies. Some of the prototypes we are working on include crediting your Uber account, buying products on Amazon and donating to charities. Kauri Wallet The Kauri Wallet aims to be an open-source, multi-currency wallet which functions as a foundation for other features. Kauri Enhanced Enhancements to the Kauri Wallet will allow multiple accounts, pin numbers, recurring payments and more. Kauri DAEx The Kauri DAEx is a Decentralised Atomic Exchange that utilises the features of the Kauri Wallet and enables users to create safe peer to peer atomic exchanges for any currency supported by the Kauri Wallet. NavDelta NavDelta will be a payment gateway that allows users to spend NAV at any business which accepts currencies supported by the Kauri Wallet. NavMorph NavMorph is a fusion of Rimu and Kauri DAEx and will allow to privately send every cryptocurrency supported by the Kauri Wallet.
If you have made it this far: Congratulations! You have learned about how NAV evolved, what its current state is and what the future will bring. To sum all up: NavCoin has made incredible progress during last year and released many long awaited features despite the bear market. Many more exciting features are yet to come and it's going to be very interesting to see where we will stand on this day next year.
Unfortunately, the giveaway was not possible in the cryptocurrency-subreddit because of their rules, so I'm doing it here :-) As a surprise, in the next 2 hours I am going to send some NAV to everyone who wants to try out the awesome features and NavPay you read about above. To get your NAVs, all you have to do is the following:
Download the app NavPay from the Android Play Store or as a iOS user, use the NavPay website
Follow the steps to set up your mobile wallet
Backup your private key (the random words) so you could restore your wallet if your phone breaks or something like that!
Post your public address, so I can send you some NAVs
If you liked the experience, I'd be happy to hear back from you :)
Introducing NanoVault, an open source wallet for Nano
Hello /nanocurrency, my name is Andrew and over the last few months I have been building and fine tuning my open source wallet, NanoVault, which after extensive testing from the community is now ready for public usage! It aims to make Nano dead-simple to use and is available on your desktop (Windows/Mac/Linux) or on the web at nanovault.io
Late last year I heard about Nano (Then RaiBlocks) and was drawn in to investigate further by its incredible claims to solve many of the potential problems we see in Bitcoin and other cryptocurrencies. After reading the white paper and witnessing the strength of the community I decided to invest and quickly became an advocate to all of my crypto friends. I loved that Nano could deliver on all of its promises, but thought the original wallets weren’t quite doing justice to the technology. So I set out to create my own version of the wallet that was simple, easy, and safe to use. It started as a simple wallet that used your local node, and through lots of feedback and testing from community members, evolved into the more fully featured client side wallet that is ready for everyone to use today.
What is NanoVault?
NanoVault is an open source wallet application for Nano which makes it quick and intuitive to use, while remaining as secure as possible. It is fully client-side signing which means your seed and private keys are generated in your browser and transactions are signed locally. None of your sensitive wallet data is ever sent across your network or stored on any server in any format (Encrypted or otherwise).
Some of the main features
Available everywhere with no sign up or email required - use the native desktop wallet on your Windows/Mac/Linux, or use the web wallet from any device at any time.
Security focused: All of the handling of sensitive information happens locally in your browser only and even that data is encrypted when the wallet is locked. (So there is no need for server-based authentication measures such as 2FA)
Store labels for your own accounts and others in the address book, which is fully integrated for easy usage into every part of the wallet.
Track the balance of your accounts in your local currency/Bitcoin (Or hide it and only show Nano)
Use your client side GPU or CPU to compute Proof of Work, or use our blazing fast GPU cloud server to show off the true speed of Nano.
Easily and safely export your wallet to your other devices using a QR code, link, or file that is encrypted by your wallet password.
Fully configure how the wallet operates - change the display denomination, wipe your data on every usage (Like MyEtherWallet), automatically lock the wallet on close and after inactivity and more.
Plus more to come - new features are being added based on all of the feedback provided by users of the community.
Create a new wallet or import your seed from any existing Nano wallet Make 100% sure to save your seed, it is the master key to your accounts, and the only way to recover your wallet
Set a password for your wallet. This is used to encrypt your sensitive information, and is used to unlock the wallet. (While the wallet is locked, new blocks cannot be signed so sending, receiving, creating accounts, etc is disabled)
You are now ready to send and receive Nano with your accounts!
How does it work?
How is data stored?
By default, your wallet data is stored in your browsers local storage, encrypted by the password you set on your wallet (If desired, you can change the application settings to never store any wallet data). Other data related to the application, such as your settings and address book are also stored in your local storage. They can be cleared completely using the application settings page if needed. No data at all is ever stored on a server, and only public Nano network transaction information is ever sent across the network.
We have a list of things we are looking at adding in the very near future which you can see on the NanoVault Road Map. What ends up being focused on first will be highly driven by what the community requests, so make your opinion heard! Join us on Discord, keep up to date on Twitter, or submit any bugs or feature requests on GitHub.
Our NanoVault Representative
In an attempt to help decentralize the network, I have also made our node available as a representative. The node is hosted on Amazon AWS and has proven incredibly reliable, even through all of the best stress tests we have undertaken so far. If you have not changed your representative yet, consider using ours at: xrb_3rw4un6ys57hrb39sy1qx8qy5wukst1iiponztrz9qiz6qqa55kxzx4491or
Thank you to the many people in this amazing Nano community who have helped me test the application and improve its features to gear it up for this public launch. It has been incredibly helpful, and I have no doubt that it is only the beginning for both NanoVault and the Nano community at large!
If you have any questions, feel free to ask them below or in our Discord server, and I will do my best to respond. You can also find me in the Nano Discord servers @Cronoh - Thanks everyone!
Storage space: I am using an 8 GB microSD card for the OS, and a 128 GB USB drive for data. Minimums I would recommend: 8GB SD card and 32 GB USB drive.
Reddcoin Core client version: v22.214.171.124-a8767ba-beta (most recent version at this moment). ↳ Screenshot
You need the OS; Lubuntu. Download Lubuntu (707 MB) for the Raspberry Pi: https://ubuntu-pi-flavour-maker.org/download/. It's a .torrent download, so you will need a BitTorrent client. Message me or post in this thread if you need help with this.
You need software to write the OS to the SD card. I use Etcher. Download Etcher: https://etcher.io/.
Select image: select the lubuntu-16.04.2-desktop-armhf-raspberry-pi.img.xz file.
Select drive: select your microSD card.
Plug the SD card into your Raspberry Pi and power it up.
Lubuntu should boot up.
Set up Lubuntu, connect to the internet (wired or wireless). ↳ As username, I chose "rpi3b". You will see this username throughout this whole tutorial.
Make sure date and time are correct ([Menu] > System Tools > Time and Date). ↳ Click on Unlock to make changes. I personally change Configuration to "Keep synchronized with Internet servers". ↳ Screenshot
Reboot ([Menu] > Logout > Reboot). I am connected to wifi, but have issues getting wifi to work on initial boot. A reboot solves this issue.
Make sure system is up-to-date, install never versions.
Open LXTerminal ([Menu] > System Tools > LXTerminal). ↳ Screenshot
Enter the following in LXTerminal: sudo apt update && sudo apt upgrade ↳ Screenshot
You will be asked if you really want to continue. Enter Y (yes).
Updates are being installed! Wait until it's finished.
Install programs that will be used in this tutorial.
GParted: to partition the USB drive.
Htop: to see the amount of memory (RAM) and swap that is in use.
Enter the following in LXTerminal to install these 2 programs. sudo apt install gparted && sudo apt install htop ↳ Screenshot
Create 2 partitions on the USB drive: 1) Swap partition 2) data partition (for the Reddcoin blockchain) The swap partition is necessary: The Reddcoin wallet can be memory intensive. To prevent any crashes or freezes, add 2 GB of 'virtual' memory by creating a swap partition.
Important: Backup your USB drive if needed. The USB drive will be formatted, so the data on the USB drive will be wiped.
Please use the USB drive solely for this purpose, do not combine it with other stuff.
Keep your USB drive plugged in, do not (randomly) plug it out.
Plug your USB drive in.
GParted will be used to create the partititons. Start GParted via LXTerminal: sudo gparted ↳ Screenshot
Apply the changes. Click on the check mark or select Edit > Apply All Operations. ↳ Screenshot ↳ Screenshot
Important: The name of the swap partition is needed later, so please write it down. Mine is /dev/sda1 (first partition on first drive (drive 'a')). ↳ Screenshot
Reboot. After the reboot, the data partition you just created should be visible on your desktop. ↳ Screenshot
The swap partition is created, so now we can enable and use it.
The swap in use can be monitored with the program Htop. Open Htop ([Menu] > System Tools > Htop) to see the 'Swp' (swap) in use. ↳ Screenshot By default, swap is not used, so 0K. ↳ Screenshot You can leave Htop open.
To enable the swap partition, open LXTerminal and enter the following commands: (Assuming /dev/sda1 is your swap partition.)
Unpack the file (large file, takes around 15 minutes to unpack): sudo xz -d bootstrap.dat.xz ↳ Screenshot
After a successful unpack, your will find the file bootstrap.dat in your USB root folder. ↳ Screenshot
On the first run of the Reddcoin Core client, it will ask for a data directory to store the blockchain and wallet data.
Start the Reddcoin Core client: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
The welcome screen will appear and ask you about the data directory. I suggest a new folder on your USB drive, I picked blockchain. The directory will be created with all the necessary files. ↳ Screenshot
Click on the three dots (...) on the right. ↳ Screenshot
Click on Create Folder at the upper right corner. Type and enter in the folder name. (In my case: blockchain.) Click on Open. ↳ Screenshot ↳ Screenshot ↳ Screenshot
After selecting the directory, the Reddcoin Core client will start. Wait till it's fully loaded and close it.
Move the bootstrap.dat file to your data directory you selected in the previous step. By doing this, Reddcoin Core will use the bootstrap.dat file to import the blockchain, which speeds up syncing. sudo mv bootstrap.dat /media/rpi3b/usb/blockchain/ (Assuming blockchain as data directory.) ↳ Screenshot
The Reddcoin Core client set up is completed, but you still have to sync fully with the blockchain before you can send, receive and stake.
Keep the client running until it's fully synchronized. It will use the bootstrap file first, and download the rest of the blockchain to complete the sync. This can take some time (it took 2 days for me). Syncing the blockchain uses a lot of resources, so the software may react slow.
You can see the progress in the debug window (Help > Debug window). ↳ Screenshot
When the synchronization is completed, the red (out of sync) will disappear on the Overview screen! ↳ Screenshot
When synchronization is complete, you can start staking your Reddcoins.
You can write down your private key or copy and save it in a document. Make sure you save it somewhere only you can access it.
To import later: Debug window -> Console -> importprivkey [label] [label] is optional. ↳ Screenshot (without a label) ↳ Screenshot (with a label)
Boot with only 1 USB drive plugged in: Make sure only the USB drive (with the swap partition and data partition) is plugged in when you boot up your Raspberry Pi. This to make sure the swap partition (/dev/sda1) is recognized correctly. If you boot up with multiple USB drives, Lubuntu might see the USB drive with the swap partition as the second drive (instead of the first drive), and ignore the 2 GB swap partition. If this happens, starting Reddcoin can render the Raspberry Pi unresponsive.
Start Reddcoin Core easier Run a shell script (.sh file), so you can start Reddcoin just by double clicking on an icon on your Desktop.
Right Click on your Desktop and select Create New -> Empty File. ↳ Screenshot
Enter a file name, make sure it ends with .sh, and click on OK. I've chosen for Reddcoin.sh. ↳ Screenshot The file will be created on your Desktop. ↳ Screenshot
Add the command to start Reddcoin to the file.
Right click on the file, select Leafpad (to open the file in a text editor). ↳ Screenshot
Add the following to the file and save the file: sudo /media/rpi3b/usb/reddcoin/src/qt/reddcoin-qt ↳ Screenshot
To be able to execute the shell script (.sh), it has to have 'execute permissions'.
Right click on the file, and select Properties. ↳ Screenshot
Click on the Permissions tab.
For Execute, select Anyone, and click on OK. ↳ Screenshot
To start Reddcoin Core, double click on the file. A new window will pop-up, asking you what you want. Execute in Terminal is what we want, so you can click on enter. ↳ Screenshot Reddcoin Core will now start. Do not close the Terminal window, you can minimize it if needed.
Minimization options Adjust minimization options, so you can safely press on the X button (the close/exit button on the upper right corner).
Activate 'Minimize on close'. Settings -> Options... -> Window (tab) -> Minimize on close. ↳ Screenshot Reddcoin will still run when you click on the X button. To close/exit Reddcoin, right click on the Reddcoin icon in the system tray (bottom right corner). ↳ Screenshot
RealVNC VNC Viewer (client) and VNC Connect (server): To remote connect to the Raspberry Pi, I use VNC Viewer ad VNC Connect from RealVNC.
After your download is finished, open the file and click Install Package. ↳ Screenshot
To run the VNC Connect once:
Open [Menu] > Run, and enter: vncserver-x11 ↳ Screenshot
To auto run on startup:
Open Default applications for LXSession ([Menu] > Preferences > Default applications for LXSession). ↳ Screenshot
In LXSessions configuration, select Autostart in the menu left.
Under Manual autostarted applications, enter vncserver-x11 and click on + Add. ↳ Screenshot ↳ Screenshot
Reboot your Raspberry Pi and check if VNC Connect is started automatically after the reboot.
When VNC Connect is running, you'll see a VNC icon on the right bottom corner. Double click the icon to open VNC Connect and to see the IP address you need to enter to connect to your Raspberry Pi. ↳ Screenshot
