Hello, everyone, It’s been a long time since you heard our team, someone thought we were gone, someone was waiting, and someone disappeared himself.
All this time we have worked hard to bring you good news. We will tell you what we have prepared for you, what events will be soon, what you can use right now and what else will be new in the year. And so, let’s go!

Preparing for listing on the exchange

The pandemic period played into the hands of the entire team and we managed to build beauty in our services. In anticipation of the exchange, the team tidied up the sites and services and connected new tools. First of all, we paid attention to the preparation of all services for a foreign audience, taking into account its mentality.
New sections, localizations, nice things, and much more to ensure the most efficient use of the TKEY resource. In addition to the new tabs, the services that we will talk about in this material, there is a special page for representatives of the exchange with the necessary documentation for listing — https://tkeycoin.com/en/documentation/.

We made adjustments to the Russian and English versions of the site, including support for Korean and Chinese for each section of the site. Professionals in their field, native speakers translated and adapted the information as it should be, and we, in turn, structured and framed it properly. So welcome!

https://preview.redd.it/hcnhws2zve151.png?width=700&format=png&auto=webp&s=30b53c5c4f3c192c39518f66941dcfdfc5b420f5
We will update language support for the site, and soon it will include support for all languages that are available in the mobile app.

QR Codes for Asian Audience


https://preview.redd.it/bv08bzm0we151.png?width=496&format=png&auto=webp&s=338ba001c3a5d6999347165e7bd725b5be7f4913
Our friends and residents of Asian countries actively use QR codes in their lives, both when paying in stores and when working with websites. QR codes are used almost everywhere when renting a car or bike, we just open the phone, scan and the mode of transport becomes available for use, anything is available for rent, even a battery, even an umbrella.
“It was a hot May day. Seven-year-old Wang Jiaozui came out of school and saw his grandfather, who came to pick him up. He was standing in the sun, and his shirt was soaked with sweat. Jiaozui invited the grandfather to buy a cold Cola in the shop, but he forgot her purse at home. It turned out that this is not important — the boy took his grandfather’s smartphone and called the payment app with a QR code on the screen.” ©
What to say if QR codes are used even to identify entire farms. By pasting QR codes on farm buildings and then scanning them, government inspectors can quickly figure out who owns the building and whether its owners are violating any laws.

We must be on the trend! Now a special library generates QR codes for the desired page, any tab on the site tkeycoin.com in Chinese and Korean-accompanied by a QR code that leads to the requested page: fast, convenient, and simple.
https://preview.redd.it/73rscop3we151.png?width=700&format=png&auto=webp&s=c83229e56d612450370b43b06910225701454c60
Providing this opportunity to our colleagues and future users of Tkeycoin from Asia is a friendly approach and most importantly, a strategic step on our part. After implementing QR codes, we are undoubtedly drawn into the convenience of this function, which we recommend to You:) If you like it, we will make QR codes on the Russian and English versions of the site.

Buying and withdrawing cryptocurrency to a Bankcard


https://preview.redd.it/9i8ykpv5we151.png?width=700&format=png&auto=webp&s=3a31d0a463de5e08f94a5b27a472fb8b53ab044e
On the site, you can now buy Bitcoin for pound, dollars, euro, and any other currency. This is a powerful automated service for instant exchange of fiat currencies for cryptocurrencies. The system works around the clock and seven days a week, allowing everyone to conduct exchanges at any time of the day and in the shortest possible time.
Withdrawal to a Bank card will be available until the end of the month, we finish the details, the page is available now, and the withdrawal itself will be activated during this week. You can buy Bitcoin, Ethereum, or any other currency right now.

https://preview.redd.it/o8z0c4b7we151.png?width=700&format=png&auto=webp&s=b4d684f09acd914316c986482b8dadf88718c618
These features are the future for the function of purchasing any product or service for TKEY at any point of sale, which will form the basis of the mobile app, quickly, conveniently, and most importantly, observing the letter of the law.
All we do is build an Empire that is being built before your eyes. Every service and product is connected, so any update promises the appearance of even more cool and effective features than before.

Buying cryptocurrency for pound, dollars, euros, and other currencies

At the end of February, we told you that we are working on building a payment service that will include the provision of services: buy cryptocurrencies, sell a cryptocurrency, withdraw cryptocurrency to Bank cards, etc.
This day has come, now you can buy Bitcoin (BTC), Ethereum (ETH), Tether USDT, Basic Attention Token (BAT), Algorand (ALGO), Tron (TRX), OKB (Token Okex.com).

https://preview.redd.it/1pm2cnv8we151.png?width=700&format=png&auto=webp&s=69473d2e5ed1b8dc75189362b46906752be29895
The purchase is available in any currency: Russian ruble, US Dollar, Euro, British pound, Ukrainian hryvnia, Indonesian rupiah, South Korean won, Japanese yen, Turkish Lira, Argentine peso.
As you can see, the currency corridors are quite extensive, which allows you to make exchanges fast and at a favorable rate. Just choose the right pair to exchange or buy, available fiat currencies: RUB, USD, EUR, GBP, UAH, IDR, KRW, JPY, TRY, ARS, available cryptocurrencies: BTC, ETH, BAT, USDT, ALGO, TRX, OKB.
Even if this wide list does not include the currency you want to buy, such as Bitcoin or USDT, it’s okay — the service will automatically convert your currency into the payment currency and the Bank will make the exchange. Exchanges take place within 1–3 minutes, it is enough to pass quick verification once, which allows you to work with a volume of > 15,000 euros per month.

https://preview.redd.it/0ln5uttawe151.png?width=700&format=png&auto=webp&s=35de9e413db35bb53f39332aa4197cd54a3e211c

Exchange of cryptocurrencies for pound, dollars, euros, and withdrawal of Bankcard

In addition to the fact that you can now easily buy a cryptocurrency for fiat currencies, pound, dollars or any other, during this week we will finish work on the withdrawal to a Bank card and you can easily withdraw your profit to the card, the most important thing is that this is a completely legal method, and all operations pass through banks and jurisdictions where work with digital assets is legalized.
This means that when you buy or make a withdrawal to the card, you get legal funds that are credited to you by the Bank or payment system.
If you are used to working with effective tools that work in a new way, or rather correctly and legally, then this service is for you. Fast crediting, easy exchange, a large selection of currency pairs, that’s what the company is betting on.
We work with the most reliable third-party partners to make your cryptocurrency process easy and convenient, and most importantly safe for You. The service supports plastic and virtual Bank cards VISA, MasterCard, MIR, and other payment systems for fast payment processing.

https://preview.redd.it/x1jnm1ccwe151.png?width=700&format=png&auto=webp&s=f86fc353ad5f207db8d233821204b521ba0b3d0e
On the exchange page, you can choose any currency pair to exchange in the opposite direction, for example, GBP to BTC or USD to BTC. Choose a suitable pair for exchange, available fiat currencies: RUB, USD, EUR, GBP, UAH, IDR, KRW, JPY, TRY, ARS, available cryptocurrencies for exchange: BTC, ETH, BAT, USDT, ALGO, TRX, OKB.
How it works
When buying cryptocurrency for the first time, your Bank reserves (holds) the requested amount, then this amount is transferred to the authorization waiting state. As soon as the Bank freezes the fiat funds, the service fixes the exchange rate at the time of creating the application, reserves the cryptocurrency, and provides you with 30–40 minutes to complete verification. After successful verification, the service charges cryptocurrency to the wallet.

Quick verification

Verification takes 2–3 minutes and requires only one time to perform operations every day. The “Know Your Customer” (KYC) procedure is necessary to exchange cryptocurrencies for fiat currencies.

https://preview.redd.it/3y0pmzrdwe151.png?width=597&format=png&auto=webp&s=01a92651b67f2df70f83082cfcd3d1fdee5491b4
As you understand, you need to pass verification 1 time, regardless of whether you withdraw funds or buy currency, after passing verification, all services are available to You without any further confirmation.

New currency

Support for other currencies, including TKEY, will be added gradually and highlighted through service updates. As for the TKEY exchange, it will become available in exchange services after listing on the exchange. Listing on an exchange allows you to automate the exchange process, link the necessary services, and most importantly, the exchange provides liquidity, which is key when we talk about exchanging for a particular currency.
We will tell you more about the operation of the service and its advantages, chips, in a separate material dedicated to the withdrawal and purchase of cryptocurrencies for fiat currencies, as well as touch on various banking issues and tell you how you can combine the SWAP service for more efficient exchange and withdrawal to the card.

Charitable activity

By making an exchange or purchase of cryptocurrency, you help children and people who need our help. We deduct 0.1% of the profit from each transaction to charity funds.
This is the fastest and most comfortable way of charity, which allows you to bring together people who are not indifferent to other people’s problems. TKEY enables people to do good deeds, and the resulting turnover profit of 0.1% is sent to charity funds every month. Together with You, we create new opportunities for people in need who need help — “Big things have small beginnings”.
How does it work?
You have made an exchange or purchase operation, the company has accumulated the volume of these operations for a month->the company has chosen a charity Fund->sent funds to the charity Fund’s account. Priority charity funds are children’s aid funds. You can always suggest a candidate for a particular Fund by sending a message to [[email protected]](mailto:[email protected]).
Why do we write Funds and not a Fund?
This is the first launch of the service, so depending on the monthly volume, we will focus on distributing funds to one charity or several. For example, if we have accumulated $ 10,000, we can distribute $ 5,000 to 2 funds. if we have accumulated $ 100, it is logical that we will only send this amount to 1 Fund. With the development of the service, we will be able to focus on several funds, which we will actively help due to the received volume.

New sections, improvements for existing services

Menu logic and site structure

The menu logic has been revised. now more items are available on the menu and they are divided into sections. Navigation through the sections has become much easier and more convenient. for some sections, QR codes are available for Russian and English-speaking audiences, and for representatives of Asian countries, all sections are available by QR code.

https://preview.redd.it/fkuhl0vgwe151.png?width=700&format=png&auto=webp&s=67450a04bdba376da59aee1d0e5a0964c896475e

FAQ

Added answers to frequently asked questions in various sections of the site, You can find the information directly on the section page, for example, TKEY-QT, SWAP or Core. Right on the page there is a FAQ section, in which we disclose answers to questions, for example: How are You going to solve the scalability problem, or why did you choose Phoenix as the logo and symbol of the project, or how do you exchange cryptocurrency for pound or dollars? As you can see, you can get answers to different questions, depending on the topic of the site section.

https://preview.redd.it/8utkvv6iwe151.png?width=700&format=png&auto=webp&s=d493ec784d74c5982486e36fe3b4bcbcb6d57335

Footer

For convenience, the site’s footer has been expanded and new sections (quick tabs) are included, which are also available in the QR-code format. In addition to various details, the footer is now accompanied by the company’s coat of arms — the Phoenix, which is the symbol of the entire community, the Phoenix Alliance.

What is waiting for us in the nearest future?

In addition to various improvements, connecting services, our team has been working every day on other main areas of the Tkeycoin project, which are already being prepared for the next release and we will tell you what updates, what plans, events, and what else will be interesting this year.

Online conference with management

An online conference in question-answer format will be organized. The main task of the conference, in addition to questions and answers, is to discuss plans, talk about new directions, touch on issues of legislation, and analyze current issues of users.
The online meeting format will allow you to get feedback and discuss a large number of issues in a short time. Questions related to technical support and other questions that can be answered through the administration will not be discussed.
The meeting involves the development, constructive, and suggestions from users for further development of the Tkeycoin project. If you are interested in participating in the conference, you can also make business proposals during it, please use the time to your advantage. We work for you.

New content: reports, new categories, useful information

Based on user feedback, we introduce new categories to our content plan:
Reports This section will be accompanied by information about the work done by the team for the month, the format of submission — abstracts, highlights. This format will help establish feedback between users and developers.
Question-answer
In addition to the content that we produce ourselves, users have questions that arise during the process of working with the project’s services, as well as during interaction with the project itself. To avoid making guesses and making up stories, we have introduced the question-answer category.
Users ask questions in comments, and the company prepares answers based on the questions and they are published in the post. Depending on the number of questions, the post generates all the answers, or the post is divided into parts if the number of questions for the past period was the largest. In addition to asking questions, you can make suggestions to the project, for example, about new features or directions.
This format also builds feedback and helps to improve all services. the most important thing is that it can not only help us but also you, as the offer and questions will help you focus on the tasks that the end-user wants to see.

TKEY-POOL (Tkeycoin pool)

We are completing the work and debugging of the official pool for Tkeycoin, this is a completely new approach for mining Tkeycoin. The pool will feature higher performance and stable architecture, a light interface, and objective commissions.
A pool is a highly loaded system that works 24/7/365, it turns out that such a product hides a sufficient number of lines of code and, most importantly, is built on a reliable architecture that can withstand +50000–100000 miners, not to mention the number of connected devices for this number of miners.
A cryptocurrency pool is a combination of the hardware power of many miners at once to increase the probability of finding a block. The reward for a block obtained by the pool is distributed among all participants.
The TKEY pool is developed taking into account the features of the Tkeycoin blockchain, including multi-blockchain, transaction model, hashing, blocks, and other nuances that are an upgrade of the blockchain among others. Together with the pool, the TKEY network is being tested: high loads, attacks, and other tests that show positive results, proving that the TKEY blockchain can work under any loads and is protected from attacks.
Our task was to: 1. Stable system for handling high loads; 2. Adaptation pool for any software; 3. Connecting any hardware for mining cryptocurrency Tkeycoin; 4. Fair remuneration calculation; 5. Security.
The main goal is for any user, regardless of the software and hardware used, to be able to connect to Tkeycoin mining via a pool. The first releases will be accompanied by a simple user-friendly interface, easy connection, instructions for various mining programs that can be connected.
In future releases, we will optimize the operation of the pool, add new features, as well as tracking functions and other nice things. any suggestions from miners and the community are interesting to us and will be implemented, so do not hesitate to send your suggestions after the launch.

TKEYSPACE updates


https://preview.redd.it/fjy2dkanwe151.png?width=700&format=png&auto=webp&s=99dedd6aa59ae7eb4d585d2ef1ddae4cc6dd50f9
Work on the TkeySpace mobile app is also not standing still. We will soon release updates for TkeySpace on Android and iOS.
This release is a complete transition to the most stable version of the mobile wallet. This means that after the update, even with the largest changes, the user will not need to completely reinstall or restore to use the new features, as before, just update the app via the AppStore or GooglePlay.
Between the previous update has been a sufficient amount of time, on average, updates are released once a month. This update will be one of the major ones. We are finishing work on the code to prepare the app for the new features that will be available this year. Besides, we are improving the app’s logic, data processing speed, optimizing the code, restoring order, and preparing for the global market.

Exchange, purchase of cryptocurrency and withdrawal to the Debit/Credit Card


https://preview.redd.it/1maxjrqowe151.png?width=700&format=png&auto=webp&s=cefd5bf1ec823049eeb25640c470024a41c0430c
In addition to pleasant optimizations, the app will display the exchange and withdrawal to a Bankcard, tab with an optimized page for exchange, withdrawal, and the purchase will be available directly in the mobile app. This upgrade will also capture the cryptocurrency exchange SWAP page, which can be evaluated after the update. Other features and new features will be announced by the developers immediately after the release.

SWAP Update

The development team is finishing work on optimizing the SWAP service. Regardless of updates, it is available in working mode 24/7/365. The team is working on improving the operation, optimizing the page, changing the interfaces, improving navigation, and speeding up query processing. This update is also among the upcoming ones, along with the pool, mobile wallets, and other news that will excite.

Network Statistics

In the network statistics section, there are several sections that will be fixed — this is the hash rate of the network and the volume of Tkeycoin. Now the volume of Tkeycoin is displayed by mTKEY, and the graph itself indicates M TKEY, the user may incorrectly understand the volume of transactions in the network, so, given the current volume, it is advisable to switch the display to TKEY, and in the future switch to mTKEY for large volumes.
TKEY is divided into cryptograms (CryptoGramm, cgr), uTKEY (keys), and mTKEY. 1 TKEY = 100 000 000 cryptograms. 1 mTKEY = 100,000 cryptograms. 1 TKEY contains 1000 mTKEY. 1 mTKEY = 0.00100000 TKEY 1 uTKEY =100 cryptograms 1 TKEY contains 1,000,000 utkeys. 1 uTKEY (keys) = 0.00000100 TKEY 1 cgr = 0.00000001 TKEY

Cryptocurrency Exchange

This issue has become the cause of mass discussions, disputes, investigations, the subject of memes, kitchen, and online conversations, that just did not happen, that TKEY is not taken anywhere, someone made guesses that we are waiting for everyone to run away, or TKEY is a world conspiracy and around some actors, you can write a book or shoot a great series, not worse than Breaking Bad.
Jokes, jokes, but the question is serious. Since the 4th quarter of last year, the company has been actively working on the issue of listing, prepared the necessary platform for this, held several meetings, negotiations, released the necessary products, figured out various transfers of funds to the blockchain, worked out many small things, many major issues that were behind the scenes. Everything is ready, and it’s time to start soon. This will be a surprise, believe it or not, and we will meet you on the stock exchanges :)

What other plans does the company have?

Enabling payment at retail outlets

After entering the exchange, we will actively engage in connecting payments to implement them and link them to TKEY. The plan, strategy, and legal component are ready.

Payment development

This implies the development of payments and services that will expand the use of digital currencies in the commercial sphere. Application on the territory of Russia will depend on the Federal law on the CFA, in any case, we plan to analyze the law, after its release, to find a legal way to implement payments based on blockchain and digital assets. Therefore, until the law is released, we are keeping this initiative in the future, and we will work on other jurisdictions that will support it.
We left some plans behind the scenes, because they will make the greatest impact on the market and the value of our asset, and this — likes silence.

What useful materials will be released soon?

How to effectively use the SWAP service together with the exchange and purchase of cryptocurrency from a Bank card?

We will tell you in detail how to use these 2 services, how to save on payments and purchases, how to exchange tokens that are very difficult to exchange, how to quickly get money for them to the card, and much more.

The law CFA

Our opinion about the law of cryptocurrencies in Russia, what to pay attention to, what to prepare for, how to act if there is a complete ban. Let’s talk about legal nuances and banking practices.

TKEY blockchain

In this material, we will talk about the blockchain, analyze the issues of the system, expand the questions on attacks, payment processing, and touch on the system of multiple chains. The article suggests your suggestions, perhaps someone will have ideas that we will implement in the chain.
At the end,
Don’t forget to ask questions in the comments or send suggestions to [[email protected]](mailto:[email protected]) we will be happy to respond and consider your requests for any of our services. Collaboration, feedback, help us make the whole platform better.
Thank you for being with us! Until new meetings, stay tuned for news, updates, because the most unexpected news comes spontaneously.

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).

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).

Remastered! – Groestlcoin WPF Desktop Wallet (v2.19.0.18)

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.

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.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

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.

Facilitating Discussion of 0.9.0 FINAL of Bitcoin Core (aka Bitcoin QT)

To facilitate a detailed discussion of some of the finer points of this update, I added numbering to each bullet in release notes, and also posted it to RapGenius, where people can annotate it if they'd like.
I'm not a programmer, but I'm curious to hear what programmers and other people smarter than me have to say about all the new changes.

Bitcoin-QT 0.9 disponível para download

The Core Developers of Bitcoin released the 0.9.0 FINAL of Bitcoin Core (aka Bitcoin QT).
DOWNLOAD:
This is a Final Version, but its the same as 0.9.0rc3
Sources: https://github.com/bitcoin/bitcoin/releases http://sourceforge.net/projects/bitcoin/files/Bitcoin/bitcoin-0.9.0/ https://bitcoin.org/bin/0.9.0/README.txt
Bitcoin Core version 0.9.0 is now available from:
https://bitcoin.org/bin/0.9.0/
This is a release candidate for a new major version. A major version brings both new features and bug fixes.
Please report bugs using the issue tracker at github:
https://github.com/bitcoin/bitcoin/issues

How to Upgrade

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), uninstall all earlier versions of Bitcoin, then run the installer (on Windows) or just copy over /Applications/Bitcoin-Qt (on Mac) or bitcoind/bitcoin-qt (on Linux).
If you are upgrading from version 0.7.2 or earlier, the first time you run 0.9.0 your blockchain files will be re-indexed, which will take anywhere from 30 minutes to several hours, depending on the speed of your machine.
On Windows, do not forget to uninstall all earlier versions of the Bitcoin client first, especially if you are switching to the 64-bit version.

Windows 64-bit installer

New in 0.9.0 is the Windows 64-bit version of the client. There have been frequent reports of users running out of virtual memory on 32-bit systems during the initial sync. Because of this it is recommended to install the 64-bit version if your system supports it.
NOTE: Release candidate 2 Windows binaries are not code-signed; use PGP and the SHA256SUMS.asc file to make sure your binaries are correct. In the final 0.9.0 release, Windows setup.exe binaries will be code-signed.

OSX 10.5 / 32-bit no longer supported

0.9.0 drops support for older Macs. The minimum requirements are now: * A 64-bit-capable CPU (see http://support.apple.com/kb/ht3696); * Mac OS 10.6 or later (see https://support.apple.com/kb/ht1633).

Downgrading warnings

The 'chainstate' for this release is not always compatible with previous releases, so if you run 0.9 and then decide to switch back to a 0.8.x release you might get a blockchain validation error when starting the old release (due to 'pruned outputs' being omitted from the index of unspent transaction outputs).
Running the old release with the -reindex option will rebuild the chainstate data structures and correct the problem.
Also, the first time you run a 0.8.x release on a 0.9 wallet it will rescan the blockchain for missing spent coins, which will take a long time (tens of minutes on a typical machine).

Rebranding to Bitcoin Core

To reduce confusion between Bitcoin-the-network and Bitcoin-the-software we have renamed the reference client to Bitcoin Core.

Autotools build system

For 0.9.0 we switched to an autotools-based build system instead of individual (q)makefiles.
Using the standard "./autogen.sh; ./configure; make" to build Bitcoin-Qt and bitcoind makes it easier for experienced open source developers to contribute to the project.
Be sure to check doc/build-*.md for your platform before building from source.

Bitcoin-cli

Another change in the 0.9 release is moving away from the bitcoind executable functioning both as a server and as a RPC client. The RPC client functionality ("tell the running bitcoin daemon to do THIS") was split into a separate executable, 'bitcoin-cli'. The RPC client code will eventually be removed from bitcoind, but will be kept for backwards compatibility for a release or two.

walletpassphrase RPC

The behavior of the walletpassphrase RPC when the wallet is already unlocked has changed between 0.8 and 0.9.
The 0.8 behavior of walletpassphrase is to fail when the wallet is already unlocked:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 Error: Wallet is already unlocked (old unlock time stays) 
The new behavior of walletpassphrase is to set a new unlock time overriding the old one:
> walletpassphrase 1000 walletunlocktime = now + 1000 > walletpassphrase 10 walletunlocktime = now + 10 (overriding the old unlock time) 

Transaction malleability-related fixes

This release contains a few fixes for transaction ID (TXID) malleability issues:

Transaction Fees

This release drops the default fee required to relay transactions across the network and for miners to consider the transaction in their blocks to 0.01mBTC per kilobyte.
Note that getting a transaction relayed across the network does NOT guarantee that the transaction will be accepted by a miner; by default, miners fill their blocks with 50 kilobytes of high-priority transactions, and then with 700 kilobytes of the highest-fee-per-kilobyte transactions.
The minimum relay/mining fee-per-kilobyte may be changed with the minrelaytxfee option. Note that previous releases incorrectly used the mintxfee setting to determine which low-priority transactions should be considered for inclusion in blocks.
The wallet code still uses a default fee for low-priority transactions of 0.1mBTC per kilobyte. During periods of heavy transaction volume, even this fee may not be enough to get transactions confirmed quickly; the mintxfee option may be used to override the default.
