Groestlcoin 6th Anniversary Release

Introduction

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.

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.

ALL NEW! – HODL GRS Android Wallet

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.

ALL NEW! – GroestlcoinSeed Savior

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.

ALL NEW! – Vanity Search Vanity Address Generator

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).

ALL NEW! – Electrum Personal Server

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.

[Social X] Architecture of A Decentralised System for Social Payment and Services

Dear fellow Reddheads:
It's been a month since the successful launch of PoSV, which marked the end of stage one of Reddcoin project. There were three main goals for stage one:
  1. fair distribution of Reddcoin to common users (tipping), miners (mining) and investors (IPCO).
  2. an innovative algorithm to secure the network and encourage ownership, participation and decentralisation (PoSV).
  3. to build out a team of super talented and trustworthy developers.
The three goals have all been achieved so it's time for us to enter stage two: the buildout of services to make Reddcoin actually useful. This is what Social X is meant for. I'm still polishing the whitepaper to make it live up to my own self-imposed high standard, but I think the time is right for me to unveil it in broad strokes. There are three main problems Social X aims to solve.

Social X: why are wallets so difficult to use?

To achieve wide adoption of Reddcoin (or any cryptocurrency) by the non-tech-savvy general public, wallets must solve the following issues:
Ever increasing blockchain size discourages users from running full-blown wallets. It takes too much time and efforts to install or repair. A common user tends to find the process frustrating or even impenetrable and is forced to either give up adoption or rely on 3rd-party service providers (e.g. exchanges, wallets using ReddAPI) to take full control of her fund. Blockchain size grows everyday and grows faster with wider adoption.
Current wallets generate private keys randomly. As a user engages in staking or normal transactions, she has to back up wallet.dat file periodically to make sure all newly generated private keys are backed up. If wallet.dat file is corrupted or lost, there is no way to recover lost fund.
Again, due to the fact that private keys are randomly generated, it's impossible for a user to share the same wallet.dat file across multiple devices (e.g. desktop, iOS, Android) and multiple platforms (e.g. Windows, Linux, Mac). Different copies of wallet.dat will get out-of-sync. A user has to manage each wallet independently, which leads to significant operational burden and risk.
It would be extremely valuable for a service provider, such as an exchange or e-commerce site, to be able to generate unique public keys to receive fund while putting the corresponding private keys in cold storage. The impact on security is significant.

Social X: why is it so hard for me to tip someone?

One essential feature of Bitcoin is pseudo-anonymity. To pay someone, you need to get hold of her impenetrable public hash key, somehow. And the hash key, i.e. the wallet address, may not be valid a moment later because the owner might have lost the corresponding private key. Ironically, this awkwardness, even backwardness, is not perceived as a disadvantage by almost all the cryptocurrencies. In fact, on the contrary, the single biggest, hottest, most wanted feature is full decentralised anonymity, which has seen the rise and fall of many cryptocurrencies and their copycats. While all the other cryptocurrencies compete with each other on this front, Reddcoin, aiming to the social currency of the digital age, moves in the opposite direction. Social lives are not possible without social identities.

Social X: why can't I use a service without giving up control?

The vast majority of 3rd-party service providers which hold fund on a user's behalf has exclusive full control of her private keys. If a service is indeed worthy, a user has no choice but to trust the 3rd party with security and integrity. It's ironic, to say the least, that cryptocurrencies which are created to remove exactly this need for blind trust in middlemen end up in a much worse position than fiat currencies due to the fact that many cryptocurrency companies are unregulated and incompetent. Then the question is: is there a way to create an ecosystem where anyone can write and provide valuable social applications in a fully decentralised fashion?

Social X: Architecture for a Decentralised System for Social Payment and Services

Social X has many components which are already being actively developed. Below I give a brief description of some of them.
  1. In the future, there will be two types of official Reddcoin wallets. QT wallet and reddcoind are full wallets required to run a full node. A second type of wallets, called thin wallets or SPV wallets will use the technology of Electrum modified and enhanced to support PoSV and staking. These wallets include mobile wallets on iOS, Android, next-generation Social Wallet on desktop and wallets inside browsers (Chrome/Firefox/Safari). I've already finished writing and started testing the reference implementation of Reddcoin Electrum server and client. Each client only needs to download 25M of data vs the current full blockchain at 660M. This is how we solve the blockchain size problem.
  2. All our official wallets, whether full or thin, will be deterministic. All private keys are generated deterministically from a long passphrase. This passphrase is all you need to remember and backup and with it you can fully recover your wallet and funds anytime anywhere. You will also be able to support multiple wallets on multiple platforms and devices and they will all be in sync. This is how we solve the portability problem.
  3. All our official wallets, whether full or thin, will be hierarchical. They will allow users to generate public keys on demand while keeping private keys in cold storage. This is how we solve the cold storage problem.
  4. I'm writing code (~30% finished) for sth we call Reddcoin Social ID (Redd-ID):
    • It's a new service provided at the blockchain level.
    • It allow users to associate a username with one private key.
    • The user can choose to bundle extra information such as email, address and avatar.
    • The information is public and embedded in the blockchain. As a result, any user can send Reddcoin to another by simply specifying the recipient's Redd-ID.
    • Redd-ID registration costs Reddcoins. The costs vary depending on many factors such as the length of the username. For example, we expect popular names like tom to cost at least 7 figure.
    • Redd-ID registration is verified in PoSV blocks. Therefore all active Reddcoin stakers will be the provider of Redd-ID service.
    • Redd-ID registration fee goes to the Reddhead who successfully mints the PoSV block that verifies and confirms the registration. In a sense, it will feel like a lottery. And this is why this service doesn't make sense for any PoW coin where each block is pool-mined.
    • Redd-IDs can be transferred to new addresses and by default auto-expire annually and can be renewed.
    • Small Reddcoin holders, as long as they keep staking, may double, triple or 10x their existing holdings just by receiving registration fees.
    • Businesses and organisations can register usernames for purposes like receiving donation.
  5. There will be several services available to provide more ways for Redd-ID to be used on Internet. I don't want to disclose all our cards here. Please wait for my whitepaper and see what we have for you as surprises. Meanwhile, do share with us how you imagine Redd-ID can be used.
  6. Different components of Social X will allow decentralised tipping across all social networks. In our next-generation social tipping platform, there will be no tipbots! When you tip someone on Reddit, Twitter, Twitch, Youtube or Facebook, the tipping goes straight from local wallet, whether on your mobile or desktop to the recipient.
  7. There will be APIs to allow 3rd parties to write and offer decentralised social applications.

Social X: where are we now?

  1. I'm finishing the whitepaper in coming weeks (while writing a lot of code). The whitepaper will contains much more information than this post.
  2. Reddcoin Electrum wallets for iOS and Android are being actively developed.
  3. Reddcoin full wallets (QT/reddcoind) are already hierarchical deterministic in the development branch and are being internally tested.
  4. The Social Tipping Platform is being actively developed.
  5. I need volunteers to host and test Reddcoin Electrum server and clients. I'll make a separate post next week.

Epilogue

Below I'll only answer questions selectively. Much more details will be available in the whitepaper and there is no reason to jump the gun and repeat it here. Stage one took us 6 months. We expect stage two to take 6 months also. It may be the most exciting period in the history of Reddcoin project.

Groestlcoin Release September 2018

Introduction

As always, the past 3 months since 22nd June have been crazy busy. The bears might still be around, but the show must go on and of course has not slowed the Groestlcoin development team in the slightest. Here’s a quick overview of what has already happened since the last release: - Integrated into the bitbns exchange, with the ability to buy Groestlcoin directly with the Indian Rupee. - Groestlcoin Rebrand Vote – Whilst there was much talk and push for a rebrand vote, the overall result was almost unanimously in favour of keeping our unique and conversation-starting name. With just 83 votes to Rebrand, and 2577 votes to No Rebrand. Thank you for all who voted, the funds raised are being used to fund ongoing hosting and development costs. - Integrated into the Cryptobridge exchange. Cryptobridge is a popular decentralised exchange where you always hold the private keys to your funds, only YOU have access to them. - Groestlcoin has been added to SimpleSwap – Groestlcoin can now be swapped with over 100 other cryptocurrencies, without signing up! - Groestlcoin has been added to UnoDax, one of the leading cryptocurrency exchanges in India, with TUSD, BTC and INR trading pairs. - Groestlcoin has been added to SwapLab.cc, where you can buy Groestlcoin using Bitcoin and over 50 other altcoins. Purchasing with VISA/Mastercard is coming VERY SOON. Discussed later: - Groestlcoin has been listed on #3 largest exchange in the world on volume, Huobi Global! More on this to come further on in the announcements. - Groestlcoin has been added to the Guarda Multi-Currency Wallet. - Groestlcoin has been added to Melis Multi-Device, Multi-Account, Multi-Platform, Multi-Signature advanced wallet! Already this list is far more than most other cryptocurrencies have achieved in the past 3 months. But this is just the tip of the iceberg of what has been developed.

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!

Melis Wallet

The the most advanced wallet for Bitcoin, Bitcoin Cash, Litecoin and now Groestlcoin.
With Melis you have the complete control of your bitcoins and private keys, you can define spending limits policies and make use of two or more factors authentication. Melis is open source, published on GitHub.

How Melis Works?

You can create as many accounts as you want. An account is a part of your wallet that can be customised to your requirements. You can choose how many co-signers are required to spend funds. The accounts are completely independent and act like separate wallets from each other but can be accessed via the same details. A core feature of Melis is the ability to set a ‘primary’ device. With this you can set an account as ‘Secure’ so it is only viewable (and accessible at all) from the Primary device. You can have a savings account hidden from the outside world whilst also having your ‘spending’ funds available on the go. With Melis you can create a multi-signature account between N people, where up to N signatures are required to sign a transaction, choosing if any of those should be mandatory.

Blockchain Financials mission

We're not here to reinvent the wheel. We're here to make it run smoother for you, and we provide some of the most useful services you'll find on the internet, made in a way that is easy to understand and use on a daily basis. In short, we're a bunch of people that claim to be Crypto Evangelists. We strongly believe in cryptocurrencies, and our main promise is to push them up so more people get involved and take all the advantages they offer.

More information from Blockchain Financial

Back in 2014, the world was taken by storm when Facebook approved the first cryptocurrencies tipping apps. The first was for Dogecoin, and the second was for multiple coins.
The project was hosted on whitepuma.net, and persisted for almost two years, built up a massive user community and gave a home to Bitcoin, Litecoin, Dogecoin and dozens of other bitcoin-based altcoins.
After very active months, the tipping hype started to fade away. Then, the developers decided to jump into the next stage: bringing not only tipping, but also mining and a widget that could be embedded on websites to allow everyone to accept payments. Sadly, the work was never completed because the project started to require an unsustainable amount of resources. Then, in a painful decision, a shutdown was announced by December 2015.
A couple of months after whitepuma.net was closed, the source code was released by its creator as Open Source on GitHub. But it wasn't maintained.
Now, some of the original members of the dev and admin teams gathered up with a handful of the WhitePuma's elite users, and decided to make something good with the best pieces of the old source code. That, with fresh new ideas and the power of the BardCanvas engine, synthesized the core of Blockchain Financial.

Groestlcoin Core v2.16.3 - Please Update ASAP

A new major Groestlcoin Core version 2.16.3 is now available for download which includes both a Denial of Service component and a critical inflation vulnerability, so it is recommended to upgrade to it if you are running a full Groestlcoin node or a local Groestlcoin Core wallet.
v2.16.3 is now the official release version of Groestlcoin Core. This is a new major version release with a very important security updates. It is recommended to upgrade to this version as soon as possible. Please stop running versions of Groestlcoin Core affected by CVE-2018-17144 ASAP: These are 2.13.3 and 2.16.0.
As a result in this, all exchanges and services have been asked to upgrade to this version, so please be patient if wallets go in to maintenance mode on these services.

What's new in version v2.16.3?

This is a major release of Groestlcoin Core fixing a Denial of Service component and a critical inflation vulnerability (https://nvd.nist.gov/vuln/detail/CVE-2018-17144) exploitable by miners that has been discovered in Groestlcoin Core version 2.13.3 and 2.16.0. It is recommended to upgrade to 2.16.3 as soon as possible. If you only occasionally run Groestlcoin Core, then it's not necessary to run out and upgrade it right this second. However, you should upgrade it before you next run it. If you know anyone who is running an older version, tell them to upgrade it ASAP. Stored funds are not at risk, and never were at risk. At this time we believe over half of the Groestlcoin hashrate has upgraded to patched nodes. We are unaware of any attempts to exploit this vulnerability. However, it still remains critical that affected users upgrade and apply the latest patches to ensure no possibility of large reorganizations, mining of invalid blocks, or acceptance of invalid transactions occurs.

The Technicals

In Groestlcoin Core 2.13.3, an optimization was added (Bitcoin Core PR #9049) which avoided a costly check during initial pre-relay block validation that multiple inputs within a single transaction did not spend the same input twice which was added in 2012 (Bitcoin Core PR #443). While the UTXO-updating logic has sufficient knowledge to check that such a condition is not violated in 2.13.3 it only did so in a sanity check assertion and not with full error handling (it did, however, fully handle this case twice in prior to 2.1.0.6). Thus, in Groestlcoin Core 2.13.3, any attempts to double-spend a transaction output within a single transaction inside of a block will result in an assertion failure and a crash, as was originally reported. In Groestlcoin Core 2.16.0, as a part of a larger redesign to simplify unspent transaction output tracking and correct a resource exhaustion attack the assertion was changed subtly. Instead of asserting that the output being marked spent was previously unspent, it only asserts that it exists. Thus, in Groestlcoin Core 2.16.0, any attempts to double-spend a transaction output within a single transaction inside of a block where the output being spent was created in the same block, the same assertion failure will occur. However, if the output being double-spent was created in a previous block, an entry will still remain in the CCoin map with the DIRTY flag set and having been marked as spent, resulting in no such assertion. This could allow a miner to inflate the supply of Groestlcoin as they would be then able to claim the value being spent twice.
Groestlcoin would like to publicly thank Reddit user u/Awemany for finding CVE-2018-17144 and reporting it (https://lists.linuxfoundation.org/pipermail/bitcoin-core-dev/2018-Septembe000064.html). You deserve gratitude and appreciation from cryptoworld, and you have ours.

• Ability to continue finding keys after first one is found • Includes warning on startup if connected to the internet • Ability to output keys to a text file (And shows button to open that directory) • Ability to make your match case sensitive (Where possible) • Show and hide the private key with a simple toggle switch, and copy the private key straight to your clipboard • Show full output of commands • Includes statistics whilst the application is running • Ability to choose between Processor (CPU) and Graphics Card (GPU) • Automatically detects 32 or 64 bit systems • Features both a Light and Dark Material Design inspired Themes • EasyVanity's search is probabilistic, and the amount of time required to find a given pattern depends on how complex the pattern is, the speed of your computer, and whether you get lucky. • EasyVanity includes components to perform address searching on your CPU (vanitygen) and your OpenCL-compatible GPU (oclvanitygen). Both can be built from source, and both are included in the Windows binary package. • Prefixes are exact strings that must appear at the beginning of the address. When searching for prefixes, Easyvanity will ensure that the prefix is possible, and will provide a difficulty estimate. • The percentage displayed just shows how probable it is that a match would be found in the session so far. If it finds your address with 5% on the display, you are extremely lucky. If it finds your address with 92% on the display, you are unlucky. If you stop EasyVanity with 90% on the display, restart it, and it finds your address with 2% on the display, your first session was unlucky, but your second session was lucky. • EasyVanity uses the OpenSSL random number generator. This is the same RNG used by groestlcoin and a good number of HTTPS servers. It is regarded as well-scrutinized. Guessing the private key of an address found by EasyVanity will be no easier than guessing a private key created by groestlcoin itself. • To speed up address generation, EasyVanity uses the RNG to choose a private key, and literally increments the private key in a loop searching for a match. As long as the starting point is not disclosed, if a match is found, the private key will not be any easier to guess than if every private key tested were taken from the RNG. EasyVanity will also reload the private key from the RNG after 10,000,000 unsuccessful searches (100M for oclvanitygen), or when a match is found and multiple patterns are being searched for. • Free software - MIT. Anyone can audit the code. • Written in C# - The code is short, and easy to review.

Groestlcoin Sentinel (Android & Blackberry) – Mainnet + Testnet

What is Sentinel?

Groestlcoin Sentinel is the easiest and fastest way to track/receive/watch payments in your offline Groestlcoin Wallets. Groestlcoin Sentinel is compatible with any standard Groestlcoin address, BIP44 XPUB (Extended Public Key) BIP49 YPUB and BIP84 ZPUB
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 particular wallet.

What's New?

Welcome to the FLO subreddit! Here you can learn about FLO and its use as a worldwide public record in many blockchain-based applications

FLO: a worldwide public record

http://flo.cash

What is FLO?
FLO is a cryptocurrency that introduces a worldwide public record for storing information. FLO coins are needed to pay for storage capacity, and coins are issued to reward participants for their work to secure and distribute information.
FLO is used to send payments and store data. This encourages building applications because anyone has the ability to write data into FLO.
How does FLO work?
FLO is a network similar to bitcoin where the open ledger is secured by miners competing to find proof-of-work. FLO has its own ledger, called the FLO blockchain, that can be thought of as a digital public space for storing information.

Berycoin | Announcement

Berycoin | Announcement
Berycoin is officially launching by 1st of august.
What is Berycoin?
Berycoin is a decentralized blockchain project built on Bitcoin's UTXO model, with support for Ethereum Virtual Machine based smart contracts, and secured by a proof of stake consensus model. It achieves this through the revolutionary Account Abstraction Layer which allows the EVM to communicate with Berycoin's Bitcoin-like UTXO blockchain. For more general information about Berycoin as well as links to join our community, go to https://berycoin.org
Welcome to the Berycoin Ignition Main Network. This is the main network where the tokens hold value and should be guarded very carefully. If you are testing the network, or developing unstable software on Berycoin, we highly recommend using either testnet or regtest mode.
The major features of the Berycoin network include:
  1. Compatibility with the Ethereum Virtual Machine, which allows for compatibility with most existing Solidity based smart contracts. No special solidity compiler is required to deploy your smart contract to Berycoin.
  2. A Proof of Stake consensus system which is optimized for Berycoin's contract model. Any user can stake and help to secure the network. There is no voting, master nodes, or minimum amount required. There have been transactions as small as 2 Berycoin that have created blocks in the past.
  3. The Decentralized Governance Protocol is completely implemented and functional, which allows certain network parameters to be modified without a fork or other network disruption. This currently controls parameters like block size, gas prices, etc.
  4. Uses the UTXO transaction model and is compatible with Bitcoin, allowing for existing tooling and workflows to be used with Berycoin. This allows for the infamous SPV protocol to be used which is ideal for light wallets on mobile phones and IoT devices.
What is Berycoin Core?
Berycoin Core is our primary mainnet wallet. It implements a full node and is capable of storing, validating, and distributing all history of the Berycoin network. Berycoin Core is considered the reference implementation for the Berycoin network.
Berycoin Core currently implements the following:
  • Sending/Receiving Berycoin
  • Sending/Receiving QRC20 tokens on the Berycoin network
  • Staking and creating blocks for the Berycoin network
  • Creating and interacting with smart contracts
  • Running a full node for distributing the blockchain to other users
  • "Prune" mode, which minimizes disk usage
  • Regtest mode, which enables developers to very quickly build their own private Berycoin network for Dapp testing
  • Compatibility with the Bitcoin Core set of RPC commands and APIs
Berymedia linked Project::
Berycoin has a linked berymedia project, which is going to support open culture projects, content and educational courses with its unique reward program. Where everyone who is a member of platform can earn Berycoins. There are three methods of earning Berycoins.
  1. Posting articles
  2. Creating Projects for open culture
  3. Creating educational courses
  4. Staking and Mining
Berycoin is a proof of Stake cryptocurrency, where users can stake their money and earn mining rewards.
How it works?
Berycoin Mining/Minting is a peer-to-peer computer process used to secure and verify berycoin transactions. Payments from one user to another on a decentralized network.Mining involves adding berycoin transaction data to berycoin's global public ledger of past transactions.
Berymedia: Create posts, Create Projects, Create Courses. make posts and earn rewards based upon Ranks and Roles.

Create Wallet

Berycoin Core is a full node, meaning it helps verify and transmit other Berycoin transactions across the network and stores copy of the entire blockchain.
