Bitcoin Gold QT wallet unable to complete a sync since network upgrade.

I tried reindexing my local blockchain, and even downloading it from scratch all over. No matter what, it gets stuck syncing.
Any suggestions?

Help recovering from old wallet.dat for an old friend.


Hey all,
I've been in the Bitcoin space since early 2012.
I have a situation that I would love to get some assistance with, I will explain the situation momentarily. Please do not message me and ask me for the wallet.dat file it's not going to happen.
TL;DR
I have an old wallet.dat file from late 2012 or early 2013 from a coin I sold to a friend. Tried to recover the coins in 2018 and failed, later found out that someone had access to the computer and could have easily stole them. Would the current Bitcoin Core be able to read an old wallet.dat file, and is there any way to easily view the balance of a 2012 wallet.dat file without having to load the entire blockchain?
In the early days of Bitcoin as many of you OG's know, the only option to securely store your coins was to use the default Bitcoin wallet in a wallet.dat file. A friend of mine was really wanted to invest in Bitcoin but didn't know how, so I sold one to him because I didn't want him to get screwed. I installed Bitcoin QT on their home laptop, had him write down the password on a piece of paper and had him put a backup of the wallet.dat file onto a USB.
Fast forward to when the price went to $20k plus, he calls me up super excited and said he wanted to sell his coin because he could use the money and I encouraged it because from my prior experience I knew the momentum was unsustainable and I had sold a few coins of my own.
Anyway, I go over to his house and we huddle around his computer. He tells me that he upgraded the hard drive in his computer and gave me his old one and I went back to my house to get an external hard drive reader. I came back, booted up his old drive and remembered that we would have to let it sync up in order to get the coins out, and on his internet that wasn't going to happen anytime soon. He gave me the hard drive and I went home and left on Bitcoin QT overnight and in the morning I was shocked to see that there were no transactions on the wallet. Quick note, he had the wallet password in a file on his documents titled "Bitcoin Wallet Password.txt". smh.
I started to panic, and I realized how bad this looked on me. I called him and told him that there were no coins on there and asked if he had his USB stick and he told me he had lost it years ago. I frantically looked through all of my old wallet files to find any transaction that could link to his address, to show that his coins were still in there. After a while I realized I had sent the coins from the now defunct btc-e.com, and had no way to check up on the coins.
I did everything in my ability to try to recover lost data from the hard drive to no avail. I asked him if anyone else has had access to his computer, and then asked him how he replaced his hard drive because I know him well enough to know he wouldn't pull apart a laptop to replace the hard drive. He told me he took it to a shop to have it replaced a few months earlier. I suspect that I'm either trying to view the wallet incorrectly or whoever replaced his hard drive snooped on his hard drive, stole the coins and replaced the wallet.dat file and generated a new one. I have to admit, I was relieved a little bit to have an explanation to coins not being there but I could imagine he thinks I may have had something to do with it. I made a few more attempts over the years whenever I was reminded of the situation to no avail.
We kind of fell out after that and haven't spoken in a while. Recently, I saw a post on his Facebook that his wife is pregnant they are having a baby, and that's why I'm here. I would love nothing more than to be able to message him and let him know that I have 11 grand waiting for him, because I'm certain the money would mean the world to him during such a stressful time.
Any help or insights would be incredibly helpful and appreciated.

Gridcoin 5.0.0.0-Mandatory "Fern" Release

https://github.com/gridcoin-community/Gridcoin-Research/releases/tag/5.0.0.0
Finally! After over ten months of development and testing, "Fern" has arrived! This is a whopper. 240 pull requests merged. Essentially a complete rewrite that was started with the scraper (the "neural net" rewrite) in "Denise" has now been completed. Practically the ENTIRE Gridcoin specific codebase resting on top of the vanilla Bitcoin/Peercoin/Blackcoin vanilla PoS code has been rewritten. This removes the team requirement at last (see below), although there are many other important improvements besides that.
Fern was a monumental undertaking. We had to encode all of the old rules active for the v10 block protocol in new code and ensure that the new code was 100% compatible. This had to be done in such a way as to clear out all of the old spaghetti and ring-fence it with tightly controlled class implementations. We then wrote an entirely new, simplified ruleset for research rewards and reengineered contracts (which includes beacon management, polls, and voting) using properly classed code. The fundamentals of Gridcoin with this release are now on a very sound and maintainable footing, and the developers believe the codebase as updated here will serve as the fundamental basis for Gridcoin's future roadmap.
We have been testing this for MONTHS on testnet in various stages. The v10 (legacy) compatibility code has been running on testnet continuously as it was developed to ensure compatibility with existing nodes. During the last few months, we have done two private testnet forks and then the full public testnet testing for v11 code (the new protocol which is what Fern implements). The developers have also been running non-staking "sentinel" nodes on mainnet with this code to verify that the consensus rules are problem-free for the legacy compatibility code on the broader mainnet. We believe this amount of testing is going to result in a smooth rollout.
Given the amount of changes in Fern, I am presenting TWO changelogs below. One is high level, which summarizes the most significant changes in the protocol. The second changelog is the detailed one in the usual format, and gives you an inkling of the size of this release.

Highlights

Protocol

Note that the protocol changes will not become active until we cross the hard-fork transition height to v11, which has been set at 2053000. Given current average block spacing, this should happen around October 4, about one month from now.
Note that to get all of the beacons in the network on the new protocol, we are requiring ALL beacons to be validated. A two week (14 day) grace period is provided by the code, starting at the time of the transition height, for people currently holding a beacon to validate the beacon and prevent it from expiring. That means that EVERY CRUNCHER must advertise and validate their beacon AFTER the v11 transition (around Oct 4th) and BEFORE October 18th (or more precisely, 14 days from the actual date of the v11 transition). If you do not advertise and validate your beacon by this time, your beacon will expire and you will stop earning research rewards until you advertise and validate a new beacon. This process has been made much easier by a brand new beacon "wizard" that helps manage beacon advertisements and renewals. Once a beacon has been validated and is a v11 protocol beacon, the normal 180 day expiration rules apply. Note, however, that the 180 day expiration on research rewards has been removed with the Fern update. This means that while your beacon might expire after 180 days, your earned research rewards will be retained and can be claimed by advertising a beacon with the same CPID and going through the validation process again. In other words, you do not lose any earned research rewards if you do not stake a block within 180 days and keep your beacon up-to-date.
The transition height is also when the team requirement will be relaxed for the network.

GUI

Besides the beacon wizard, there are a number of improvements to the GUI, including new UI transaction types (and icons) for staking the superblock, sidestake sends, beacon advertisement, voting, poll creation, and transactions with a message. The main screen has been revamped with a better summary section, and better status icons. Several changes under the hood have improved GUI performance. And finally, the diagnostics have been revamped.

Blockchain

The wallet sync speed has been DRASTICALLY improved. A decent machine with a good network connection should be able to sync the entire mainnet blockchain in less than 4 hours. A fast machine with a really fast network connection and a good SSD can do it in about 2.5 hours. One of our goals was to reduce or eliminate the reliance on snapshots for mainnet, and I think we have accomplished that goal with the new sync speed. We have also streamlined the in-memory structures for the blockchain which shaves some memory use.
There are so many goodies here it is hard to summarize them all.
I would like to thank all of the contributors to this release, but especially thank @cyrossignol, whose incredible contributions formed the backbone of this release. I would also like to pay special thanks to @barton2526, @caraka, and @Quezacoatl1, who tirelessly helped during the testing and polishing phase on testnet with testing and repeated builds for all architectures.
The developers are proud to present this release to the community and we believe this represents the starting point for a true renaissance for Gridcoin!

Summary Changelog

Accrual

Changed

Most significantly, nodes calculate research rewards directly from the magnitudes in EACH superblock between stakes instead of using a two- or three- point average based on a CPID's current magnitude and the magnitude for the CPID when it last staked. For those long-timers in the community, this has been referred to as "Superblock Windows," and was first done in proof-of-concept form by @denravonska.

Windows / Linux Guide to using Trezor with Bitcoin Core (HWI)

This is a guide to using your Trezor with Bitcoin Core. It may seem like more trouble than it's worth but many applications use Bitcoin Core as a wallet such as LND, EPS, and JoinMarket. Learning how to integrate your Trezor into a Bitcoin Core install is rather useful in many unexpected ways. I did this all through the QT interfaces, but it's simple to script. There is a much simpler guide available from the HWI github, and the smallest Linux TLDR is here
Unfortunately, I don't have access to a Coldcard or Ledger. I'm not sure how the setpin or -stdinpass parameters are handled on that HW.

( A ) Install TrezorCTL, HWI, and build GUI

You only need to set the wallet up once, but may repeat to upgrade

( A.I ) Download extract and install HWI

  1. Download and isntall Python
  2. Download https://github.com/bitcoin-core/HWI/archive/1.1.2.zip
  3. Extract it to a working folder (assumes C:\User\Reddit\src\HWI)
  4. Change Directory (cd) to working folder cd "C:\User\Reddit\src\HWI"
  5. Setup venv python -m venv .venv
  6. Enter venv .venv\Scripts\activate.bat 1
  7. Install dependencies python -m pip install -U setuptools pip wheel
  8. Install TrezorCTL python -m pip install trezor[hidapi]
  9. Install HWI python -m pip install hwi pyside2
  10. Download github.com/libusb/libusb/releases/download/v1.0.23/libusb-1.0.23.7z
  11. Extract MS64\dll\libusb-1.0.dll from the archive
  12. Copy to pywin copy libusb-1.0.dll .venv\Lib\site-packages\pywin32_system32\

( A.II ) Build the QT UI files

  1. Download and install MSYS2
  2. Launch a mingw64.exe shell
  3. CD to working folder cd "C:\User\Reddit\src\HWI"
  4. Enter venv source .venv/Scripts/activate 1
  5. Run UI build bash contrib/generate-ui.sh

( B ) Create a Trezor wallet in Bitcoin Core (testnet)

You only need to set the wallet up once, no private key data is stored, only xpub data

( B.I ) Retrieve keypool from HWI-QT

  1. Launch hwi-qt.exe --testnet (assuming testnet)
  2. Click Set passphrase (if needed) to cache your passphrase then click Refresh
  3. Select you trezor from the list then click Set Pin (if needed)
  4. Ensure your Trezor in the dropdown has a fingerprint
  5. Select Change keypool options and choose P2WPKH
  6. Copy all the text from the Keypool textbox

( B.II ) Create the wallet in Bitcoin QT

  1. Launch Bitcoin Core (testnet) (non-pruned) 2
  2. Select Console from the Window menu
  3. Create a wallet createwallet "hwi" true
  4. Ensure that hwi is selected in the console wallet dropdown
  5. Verify walletname using the getwalletinfo command
  6. Import keypool importmulti '' (note ' caging)
  7. Rescan if TXNs are missing rescanblockchain 3

( C.I ) Grab Tesnet coins

  1. Select the Receive tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Select Create new receiving address and copy address
  4. Google "bitcoin testnet faucet" and visit a few sites
  5. Answer captcha and input your addressed copied from C.I.3

( D ) Spending funds with HWI

This is how you can spend funds in your Trezor using Bitcoin Core (testnet)

( D.I ) Create an unsigned PSBT

  1. Select the Send tab in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Verify your balance in Watch-only balance
  4. Rescan if balance is wrong (see B.II.7) 3
  5. Craft your TXN as usual, then click Create Unsigned
  6. Copy the PSBT to your clipboard when prompted

( D.II ) Sign your PSBT

  1. In HWI-QT click Sign PSBT
  2. Paste what you copied in D.I.6 in PSBT to Sign field
  3. Click Sign PSBT
  4. Copy the text for PSBT Result

( D.III ) Broadcast your TXN

  1. Select the Console window in Bitcoin Core (testnet)
  2. Ensure that the Wallet dropdown has hwi selected
  3. Finalize PSBT: finalizepsbt
  4. Copy the signed TXN hex from the hex field returned
  5. Broadcast TXN: sendrawtransaction

Final Thoughts

I did this all through the GUI interfaces for the benefit of the Windows users. Windows console is fine, but the quote escaping in windows console is nightmarish. Powershell would be good, but that throws this on a whole another level for most Windows folks.
There is also the need to use HWI-QT due to a bug in blank passphrases on the commandline. You can work around it by toggling passphrase off or on, but again, it's more than I wanted to spell out.
Footnotes:
  • 1. - Later version of python put the activate script under 'bin' instead of 'Script'
  • 2. - You can run pruned, but you need to have a fresh wallet
  • 3. - Rescan is automatic on 'importmulti' but I was pruned so it was wierd

[ANN][ANDROID MINING][AIRDROP] NewEnglandcoin: Scrypt RandomSpike

New England
New England 6 States Songs: https://www.reddit.com/newengland/comments/er8wxd/new_england_6_states_songs/
NewEnglandcoin
Symbol: NENG
NewEnglandcoin is a clone of Bitcoin using scrypt as a proof-of-work algorithm with enhanced features to protect against 51% attack and decentralize on mining to allow diversified mining rigs across CPUs, GPUs, ASICs and Android phones.
Mining Algorithm: Scrypt with RandomSpike. RandomSpike is 3rd generation of Dynamic Difficulty (DynDiff) algorithm on top of scrypt.
1 minute block targets base difficulty reset: every 1440 blocks subsidy halves in 2.1m blocks (~ 2 to 4 years) 84,000,000,000 total maximum NENG 20000 NENG per block Pre-mine: 1% - reserved for dev fund ICO: None RPCPort: 6376 Port: 6377
NewEnglandcoin has dogecoin like supply at 84 billion maximum NENG. This huge supply insures that NENG is suitable for retail transactions and daily use. The inflation schedule of NengEnglandcoin is actually identical to that of Litecoin. Bitcoin and Litecoin are already proven to be great long term store of value. The Litecoin-like NENG inflation schedule will make NewEnglandcoin ideal for long term investment appreciation as the supply is limited and capped at a fixed number
Bitcoin Fork - Suitable for Home Hobbyists
NewEnglandcoin core wallet continues to maintain version tag of "Satoshi v0.8.7.5" because NewEnglandcoin is very much an exact clone of bitcoin plus some mining feature changes with DynDiff algorithm. NewEnglandcoin is very suitable as lite version of bitcoin for educational purpose on desktop mining, full node running and bitcoin programming using bitcoin-json APIs.
The NewEnglandcoin (NENG) mining algorithm original upgrade ideas were mainly designed for decentralization of mining rigs on scrypt, which is same algo as litecoin/dogecoin. The way it is going now is that NENG is very suitable for bitcoin/litecoin/dogecoin hobbyists who can not , will not spend huge money to run noisy ASIC/GPU mining equipments, but still want to mine NENG at home with quiet simple CPU/GPU or with a cheap ASIC like FutureBit Moonlander 2 USB or Apollo pod on solo mining setup to obtain very decent profitable results. NENG allows bitcoin litecoin hobbyists to experience full node running, solo mining, CPU/GPU/ASIC for a fun experience at home at cheap cost without breaking bank on equipment or electricity.

CPU Minable Coin Because of dynamic difficulty algorithm on top of scrypt, NewEnglandcoin is CPU Minable. Users can easily set up full node for mining at Home PC or Mac using our dedicated cheetah software.
Research on the first forked 50 blocks on v1.2.0 core confirmed that ASIC/GPU miners mined 66% of 50 blocks, CPU miners mined the remaining 34%.
NENG v1.4.0 release enabled CPU mining inside android phones.

Decentralization and Community Driven NewEnglandcoin is a decentralized coin just like bitcoin. There is no boss on NewEnglandcoin. Nobody nor the dev owns NENG.
We know a coin is worth nothing if there is no backing from community. Therefore, we as dev do not intend to make decision on this coin solely by ourselves. It is our expectation that NewEnglandcoin community will make majority of decisions on direction of this coin from now on. We as dev merely view our-self as coin creater and technical support of this coin while providing NENG a permanent home at ShorelineCrypto Exchange.

ASIC/GPU Mining Pools Warning to Big ASIC Miners Due to DynDiff Algo on top of Scrypt, solo mining is recommended for ASIC/GPU miners. Further more, even for mining pools, small mining pool will generate better performance than big NENG mining pool because of new algo v1.2.x post hard fork.
The set up configuration of NENG for scrypt pool mining is same as a typical normal scrypt coin. In other word, DynDiff on Scrypt algo is backward compatible with Scrypt algo. Because ASIC/GPU miners rely on CPU miners for smooth blockchain movement, checkout bottom of "Latest News" section for A WARNING to All ASIC miners before you decide to dump big ASIC hash rate into NENG mining.
(1) Original DynDiff Warning: https://bitcointalk.org/index.php?topic=5027091.msg48324708#msg48324708 (2) New Warning on RandomSpike Spike difficulty (244k) introduced in RandomSpike served as roadblocks to instant mining and provide security against 51% attack risk. However, this spike difficulty like a roadblock that makes big ASIC mining less profitable. In case of spike block to be mined, the spike difficulty immediately serve as base difficulty, which will block GPU/ASIC miners effectively and leave CPU cheetah solo miners dominating mining almost 100% until next base difficulty reset.

How does the BitQT App work?

How does the BitQT App work?

https://preview.redd.it/81cx1yfe1pm51.jpg?width=474&format=pjpg&auto=webp&s=2ceddeda7d5dc0be5c7d4b4dfa7a715baac65b3a
In the later part of websites are the testimonials screaming out loud regarding their success.BitQT review can be quiet judgemental at this point as a result of neither these testimonials prove the legitimacy of the web site nor the live profit reviews account such
You extremely want to understand that if you opt to speculate you’ll surely not visiting recover. TheBitQT just prove this by themselves stating it not being on affiliate terms with others. Something that’s claiming that you simply’ll earn 110zero greenbacks every day is doing a true-time scam job
Perhaps, theBitQT states advertising itself on Times, CNN and Forbes however neither of them found supportive during this regard. You'll check it all by yourself. This is often the sound proof of its scamming regime throughout the globe
It doesn’t have that laser-accurate performance as in trading bitcoin you can never guarantee the minimum amount of profit you be earning the other day. Its what happens when trading with Forex

Many of the websites agree onto the proficiency ofBitQT negating the crucial and impactful proves I shared with you higher than. They are saying it’s flawless. Will something be this flawless letting you earn regarding one thousand bucks each day without charging a penny? The automated transactions are known to be deposited directly into the user’s account that is nowhere to find affiliation with. Undoubtedly, most of the revealing sites have the only supportive argument beginning with, ‘As the review suggests’. Do raise yourselves, is that this the legitimate way to prove legitimacy ofBitQT
They too argue regarding the legitimate verification method. That’s the explanation why there’s a number of complaints with reference to the current. If these products would have really worked, why not each single person select to remain off from their offices integrating with it somehow:

Merely head to the SIGN-UP section on theBitQT site, fill in your personal info, and present your registration. When acknowledged, you'll be able to be able to access our restrictive Bitcoin exchanging

To induce your exchange account in progress, you’ll have to include some assets. WithBitQT, you can create a initial investment of as low as $250, although you'll be able to contribute as a lot of as you wantoy
Since your enlistment has been acknowledged and you’ve invested some funds, you’re fully done. Simply click on ‘trade’ to receive the rewards ofBitQT’s highly rated algorithm. In case you need a hands-on approach, you can shift to manual operation by changing the settings

There’s no harm in trading in terms of cryptocurrency. We have a tendency to’re not against it. But we tend to really aim to reveal the very fact thatBitQT isn't a legitimate website to believe during this case. To actually invest in bitcoin you initially want to shop for a bitcoin wallet so as to store all bitcoins. a series of blockchain integrations which permits you to top-up and earn.

But, as stated earlier you’ve no actual guarantee concerning the number you wish to earn. Secondly, you wish to integrate your bitcoin wallet to your account and then you’ll be ready to head towards the foremost step. Here, you’ll jin a bitcoin exchange system for trading bitcoin for any different traditional currencies of the market.

It works well solely if you for legitimate sites for functioning and planning. Perhaps, it too needs a nice amount of ability and we never promise you to begin earning when you join Bitcoin Exchanger somehow. This was all aboutBitQT Review as a full fulling the aim of alerting the scam going around.


Money Forex Cluster scamThe Cash Forex Group is run by a company named CFxG which allegedly was founded by a team of experts in all kinds of areas, mainly education in the monetary trading field and network promoting.

https://preview.redd.it/0gc7ga9f1pm51.jpg?width=474&format=pjpg&auto=webp&s=5c031ac047e635c47d3ee592ab9235878613c890
These experts and their automated trading system will supposedly facilitate your to form heaps of cash. In trading solely you'll allegedly make fifteenp.c weekly on your investments. Then there are referral programs and multi-level structures that can boost your income even more. Is that t
Money FX Group scamLet’s begin this Money Forex Group review by stating the obvious, this scheme may be a total scam, you just have to look at the numbers.BitQT

When they promise you fifteen%+ weekly, it means that 60percent+ monthly, which is totally ridiculous in the important world. It means a lot of than 560zeropercent per year, therefore you'd need solely $18,00zero greenbacks to become a millionaire within year. And this is often plain impossible.

No legitimate business can create you a gradual fifteenpercent weekly, no financial markets are that predictable and that easy to trade. It may appear straightforward to you, but it really is this straightforward, a program promising fifteenp.c weekly should be a scam, there is no alternative method, the Money FX Group is a scam.

However there is additional to go through in this review.
Massive lies

Money FX Cluster testimonialThe Money Forex Cluster claims to be regulated by the subsequent institutions: FAC – Financial Conduct Authority of London, DFSA – Monetary Services Authority in Dubai, FSCA – Monetary Sector Conduct Authority of South Africa and FSA – the Monetary Services Authority of Seychelles.

But guess what, the FAC will not even exist, while the others (DFSA, FSCA and FSA) haven't issued any license whatsoever to Cash Forex Cluster. Therefore not only Money FX Group is not regulated at all, it conjointly is lying huge time regarding its regulatory status.

The fact is that it's no license whatsoever, so it cannot supply investment services legally in most countries.

This is often conjointly why they want you to deposit cryptocurrencies, they wish to remain as anonymous as potential, so that they will run away along with your cash.
Regulatory warning

Not long when we have a tendency to printed our analysis, the Financial Conduct Authority (financial regulator in Nice Britain) came up with its own warning.

The regulator said that CashFX is providing investment services without the mandatory authorization and advised the public to remain off from it. This is often a very serious argumentBiTQT.

It'd be terribly unwise to deposit money with an unregulated and basically anonymous entity, as a result of it would not be protected in any means. No matter where the cash finally ends up, this program is promising you impossible returns on investments, which in itself confirms that something is wrong.
How it works

Let’s end this Cash Forex Group review by explaining the essential principle of this investment program. It's a Ponzi theme that does no real economic activity. It just collects money from individuals and may pay out some profits, but the most recent clients’ deposits can be used for that.

This will have an inevitable outcome, the system can sooner or later crumble. It's simply a matter of your time when there can be not enough deposits to hide withdrawals and also the inevitable end can

Nobody has not been paid, that is NOBODY ….. after all you can't compound or upgrade your CFX account unless you withdraw (get paid) …. CFX are not regulated…. as a result of they use a Regulated broker (everfx) to trade…so that information is also incorrect…and judging by the actual members comments….I’d say, members are happy….. long might that continue. BUT, you must never place in more than you are prepared to lose (In SOMETHING). However do correct analysis, ask

members, don’t rely on people that play safe and stay poor. Do your own due diligence. (ps MOST sites that decision each business out as a scam…have their own links…..promoting guess what ? ….tip. SCAMS ! Beware.

Make your own stakebox. Ultimate beginners guide how to compile any wallet on AARCH64 (Raspbery pi and other SBC)

I contemplated to wrote this for a long time, so it's finally time.
As you know a lot of altcoins uses PoS (Proof-of-stake) way of "mining" coins. Which basically means, that you hold coins on your unlocked wallet and you are receiving stakes as a reward. This requires very little power and it can bring you a lot of rewards, at just 10W from the wall.
So first I am using latest Raspbian on RPI4B 4GB in this example.Setting up Raspbian is not part of this process since it's very well documented. I recommend to change user from pi to something else due to security concerns and you can also do other stuff just search "security Raspberry PI" and you find a lot of articles, but this is not the focus of this guide.
I know there are a lot of guides on the internet, but I am using like 5 sources, so it's compiled what other people wrote and some of my research.
I am using AnyDesk insted of SSH or VNC server, because it works it's ligthweit and it just works.
So after you see the gui of Raspbian, just launch terminal (CTRL + ALT + T) and do basic thing:
sudo apt-get update && sudo apt-get upgrade
Than press Y and let it run, after is finished, we need to prepare so dependency packages. Since most of the wallets using Berkeley DB 4.8 we need to obtain it.
So in terminal wrote:
cd cd Downloads wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar -xzvf db-4.8.30.NC.tar.gz cd db-4.8.30.NC/build_unix ../dist/configure --enable-cxx make sudo make install 
So wait unti it's finished and than you can delete files in Downloads folder in gui or use:
sudo rm -r [folder] 
So next thing we need to install some libraries.
sudo apt-get install git build-essential libtool autotools-dev autoconf pkg-config libssl-dev libcrypto++-dev libevent-dev libminiupnpc-dev libgmp-dev libboost-all-dev devscripts libdb++-dev libsodium-dev 
And pres y and let it run. After that another set of libraries:
sudo apt-get install libqt5gui5 libqt5core5a libqt5dbus5 qttools5-dev qttools5-dev-tools libprotobuf-dev protobuf-compiler libcrypto++- dev libminiupnpc-dev qt5-default 
And then again pres y and let it run. Some wallets need older version of libssl1.0-dev, so for for safe compiling we install that as well:
sudo apt-get install libssl1.0-dev 
Pres y and let it run. Warning don't use sudo-apt get autoremove, since it would wipe this package, since it's old.
Next thing we are going to obtain Bitcoin PPA filest, which can be done like this.
cd /etc/apt/sources.list.d/ sudo nano bitcoin.list 
Paste this in there:
deb-src http://ppa.launchpad.net/bitcoin/bitcoin/ubuntu artful main 
And CTRL+X and than y, then do this:
sudo apt-key adv --keyserver hkp://keyserver.ubuntu.com:80 --recv C70EF1F0305A1ADB9986DBD8D46F45428842CE5E sudo apt-get update 
So now we are ready for compiling. So we are going create folders. CD yourself where this folder should be situated, if you for example have plugged in some external drive. Then:
mkdir Crypto cd Crypto 
And then we have to choose wallet which you want to compile. I am choosing Streamies (STRMS) as an example, since it's pretty good coin for staking. So:
mkdir Streamies cd Streamies 
Then go to the github page and click on the green button on the left and click copy to clipboard, which gives you git link.
git clone https://github.com/Streamies/Streamies.git 
Watch the output folder which it creates, it's stated in the first two lines and copy then by highliting the text and CTRL+SHIFT+C copy it to your clipboard.
cd Streamies (this is that git created folder) ./autogen.sh ./configure CPPFLAGS="-I/uslocal/BerkeleyDB.4.8/include -O2" LDFLAGS="-L/uslocal/BerkeleyDB.4.8/lib" sudo make (this could take hours) sudo make install 
And you are done, files is going to be in folder /uslocal/bin (DO NOT delete git created folder, because you are going to need it for faster compiling, when wallet get's and update.)
cd /uslocal/bin 
Now you can list files by:
ls 
And then you can copy/move them where ever you want by using:
sudo mv * [destination full path] 
Let it run and go back to folder where you move those files.
sudo chmod +x streamies-qt (since we want to run wallet) 
In most cases compiled files are going to in format of "shared library" so we need to create script to run it. Open up a text editor from gui or through nano. And paste this to that file:
#!/bin/bash ./streamies-qt 
And save it as a sh file, for example run.sh. Then we need to make it runnable so:
sudo chmod +x run.sh 
Now to run it, it's just:
./run.sh 
And here we are glorious GUI wallet appears and you are done, you can paste blockchain, wallet.dat from other sources, so this migration is pretty easy and you, if you have it on for exaple flash disk.
So this is basic how to compile QT wallets on AARCH64. I am running 7 wallets, 2 of those are Masternodes and RPI 4B 4GB would handle way more, I am at best on half of my RAM.
Some wallets need more package, but it's not much of and issue, since compiling stops and you just copy paste nape which is missing put it in the google and add "apt-get" after the name of package and you are going to see, what is the name of the packages so it can be retreived from package assinstant aka apt-get. So basically:
sudo apt-get install [package name] 
Then press y and again wrote:
sudo make 
This process is going to continue where it was left off, so nothing is going to run from beginning.
Updating wallets is basically exactly same, just repeat steps from "git clone" and after that proceed as it was written above.
So I hope this helps some of you, to use this at home and not on some VPS, if you are anxious as me, to host my wallets on remote server.

There is no "best" hardware wallet.

My first hardware wallet was a spare computer that never connected to a network and I used it to sign transactions with bitcoind by printing the txid's on paper. That was the "best" hardware wallet.
Then my spare laptop that never connected to a network and ran bitcoin-qt to was the "best" hardware wallet. Then that laptop was upgraded to Electrum (edited: typed "Ethereum" in original post).
Then I moved to the first-generation Trezor. And now I have a Ledger Nano S. Eventually I will move to something else that hasn't even been released yet.
Bottom line: There is no "best" hardware wallet. There are only wallets that are the "best" for the person using them at that specific time.

TecraCoin works on core wallet upgrade

TecraCoin works on core wallet upgrade

What is a TecraCoin TCR Wallet?

Crypto wallet is the basic software needed to use the cryptocurrencies properly. Every blockchain of cryptocurrency must have its own basic wallet (the most commonly used are the desktop and server ones), which is usually composed from the name of the cryptocurrency and the word “Core”, for example Bitcoin Core, Litecoin Core etc. Every developing blockchain project has to implement Core updates in order to make the system more secure and solid because the correct functioning of the basic wallet is crucial . (Tecra’s basic wallet is “Tecra QT wallet” — you can download from the GutHub — https://tecracoin.io/wallets)
This week, Teсra developers have prepared the first part of the update of the above mentioned wallet. Since the blockchain used by Tecra is the fork of the widely recognized Zcoin blockchain, we are working on the upgrade from version 11 to version 14 which includes all of the changes from the versions 12 and 13. The most significant reason for such changes was to enhance the masternodes and increase the safety of our blockchain.

Why is this update essential?

Masternodes are awarded in order of precedence. According to the previously set order, the last MN to receive the reward is transferred to the end of the queue, and from the next block, the reward will be given to the next MN. In every block, there is a vote between nodes to decide which one of the MasterNodes will get the reward from this particular block. However, there might be the situation in which MN that was supposed to get the reward will not receive it.
Currently The MN communication between nodes takes place off-chain, and the data is stored in the memory, without being saved to the blockchain. The winner of the voting receives the reward via the payment in the next block. However, sometimes it might be possible for the node to “unpin” from the rest of the blockchain’s node network and conduct its own voting, contrary to the majority of MNs’ preferences. This leads to a MN blockage and the approved winner of the vote might not receive the reward.
Following Zcoin’s solution Tecra will introduce a new masternodes launching and voting system. It will shift the process of their activation and voting directly to blockchain transactions. In result, we create the “deterministic masternodes” which cannot “unpin” from the voting chains. This guarantees that the approved winner of the vote will definitely be the only one. This will be the biggest change introduced when updating to Core 14.

Reddcoin (RDD) 02/20 Progress Report - Core Wallet v3.1 Evolution & PoSV v2 - Commits & More Commits to v3.1! (Bitcoin Core 0.10, MacOS Catalina, QT Enhanced Speed and Security and more!)

Reddcoin (RDD) Core Dev Team Informal Progress Report, Feb 2020 - As any blockchain or software expert will confirm, the hardest part of making successful progress in blockchain and crypto is invisible to most users. As developers, the Reddcoin Core team relies on internal experts like John Nash, contributors offering their own code improvements to our repos (which we would love to see more of!) and especially upstream commits from experts working on open source projects like Bitcoin itself. We'd like tothank each and everyone who's hard work has contributed to this progress.
As part of Reddcoin's evolution, and in order to include required security fixes, speed improvements that are long overdue, the team has up to this point incorporated the following code commits since our last v3.0.1 public release. In attempting to solve the relatively minor font display issue with MacOS Catalina, we uncovered a complicated interweaving of updates between Reddcoin Core, QT software, MacOS SDK, Bitcoin Core and related libraries and dependencies that mandated we take a holistic approach to both solve the Catalina display problem, but in doing so, prepare a more streamlined overall build and test system, allowing the team to roll out more frequent and more secure updates in the future. And also to include some badly needed fixes in the current version of Core, which we have tentatively labeled Reddcoin Core Wallet v3.1.
Note: As indicated below, v3.1 is NOT YET AVAILABLE FOR DOWNLOAD BY PUBLIC. We wil advise when it is.
The new v3.1 version should be ready for internal QA and build testing by the end of this week, with luck, and will be turned over to the public shortly thereafter once testing has proven no unexpected issues have been introduced. We know the delay has been a bit extended for our ReddHead MacOS Catalina stakers, and we hope to have them all aboard soon. We have moved with all possible speed while attempting to incorproate all the required work, testing, and ensuring security and safety for our ReddHeads.
Which leads us to: PoSV v2 activation and the supermajority on Mainnet at the time of this writing has reached 5625/9000 blocks or 62.5%. We have progressed quite well and without any reported user issues since release, but we need all of the community to participate! This activation, much like the funding mechanisms currently being debated by BCH and others, and employed by DASH, will mean not only a catalyst for Reddcoin but ensure it's future by providing funding for the dev team. As a personal plea from the team, please help us support the PoSV v2 activation by staking your RDD, no matter how large or small your amount of stake.
Every block and every RDD counts, and if you don't know how, we'll teach you! Live chat is fun as well as providing tech support you can trust from devs and community ReddHead members. Join us today in staking and online and collect some RDD "rain" from users and devs alike!
If you're holding Reddcoin and not staking, or you haven't upgraded your v2.x wallet to v3.0.1 (current release), we need you to help achieve consensus and activate PoSV v2! For details, see the pinned message here or our website or medium channel. Upgrade is simple and takes moments; if you're nervous or unsure, we're here to help live in Telegram or Discord, as well as other chat programs. See our website for links.
Look for more updates shortly as our long-anticipated Reddcoin Payment Gateway and Merchant Services API come online with point-of-sale support, as we announce the cross-crypto-project Aussie firefighter fundraiser program, as well as a comprehensive update to our development roadmap and more.
Work has restarted on ReddID and multiple initiatives are underway to begin educating and sharing information about ReddID, what it is, and how to use it, as we approach a releasable ReddID product. We enthusiastically encourage anyone interested in working to bring these efforts to life, whether writers, UX/UI experts, big data analysts, graphic artists, coders, front-end, back-end, AI, DevOps, the Reddcoin Core dev team is growing, and there's more opportunity and work than ever!
Bring your talents to a community and dev team that truly appreciates it, and share the Reddcoin Love!

Whew! No wonder it's taken the dev team a while! :)
TL;DR: Trying to fix MacOS Catalina font display led to requiring all kinds of work to migrate and evolve the Reddcoin Core software with Apple, Bitcoin and QT components. Lots of work done, v3.1 public release soon. Also other exciting things and ReddID back under active dev effort.

Peercoin v0.9 (Codename Strider) Released - Includes Update to PoS Reward Economics - Hard Fork is June 8th, 2020 - Upgrade Today!
NOTE: If you are new to Peercoin, check out the Peercoin Primer, a short 5 part video series covering the basic fundamentals of Peercoin.

https://preview.redd.it/3v73ap26c4z41.png?width=600&format=png&auto=webp&s=67e30f6f72e7e7ba1370f74a3ad952a3d951f9dd

Peercoin v0.9 Released!

We are pleased to announce that after many hard months of work, Peercoin v0.9 (Codename Strider) is complete and a hard fork is planned for Monday, June 8th, 2020 at 12:00:00 UTC. You must upgrade your wallet client before then!

Changelog:

Peercoin release v0.9.0
  • RFC-0019: PoW Block Spacing
  • RFC-0018: PoS Rewards Adjustment
  • RFC-0017: Limit Effective Coinage to One Year
  • RFC-0015: Reduce Time Drift
  • allow staking=0 command to disable minting
  • ability to filter out mint transactions in the QT wallet

Summary

While Peercoin v0.8 (Mantis) was largely about modernizing the codebase and improving the technical capabilities of the reference node software, the v0.9 (Strider) development cycle was about the economics of the Peercoin cryptocurrrency.
Both the PoW and PoS aspects of the network have been modified. Proof-of-Work changes are rather minimal; in summary target block spacing has been set to 60 minutes, rather than having dynamic PoW block spacing target. Block spacing is currently approximately 60 minutes anyway, so this may not sound like a big change, but it stops some PoW pools from trying to game the system. By making PoW more predictable, RFC-0019 brings inflationary stability to the overall system.
That change is minor when compared to the modification of the Proof-of-Stake side of the system. Some of you may have been following the discussion on RFC-0011, which was ongoing for over a year, and you may have noticed that RFC-0011 was rejected about two weeks ago and replaced with RFC-0018.
In my personal opinion, RFC-0011 is a great idea, probably the best idea thrown around here in the last couple of years, but ultimately it's too complex and we could not get consensus about it. The gist of both RFC-0011 and RFC-0018 is that the Peercoin money supply inflates at a rate of 1% on paper, but we are nowhere near that in practice.
In the old system, in order to have PoS inflation at 1%, a full 100% of all peercoins would have to start minting and solving blocks. This is simply impossible. In reality, over the last couple years Peercoin's PoS inflation has only been between 0.10% and 0.20%, which is far from the "promised" annual 1%. Due to the very rough history of this beautiful blockchain, namely the closure of btc-e, dozens of exchange hacks and closures, as well as a couple of de-listings, we are in a situation today where nearly half of the monetary supply has not been moved for over two years and we can consider those coins lost for all intents and purposes.
The basic principle of RFC-0011 was the following: the Peercoin network promises a steady inflation of 1% on monetary supply, and if you want a cut of it: mint. In essence, if only 20% of all peercoins are minting, the effective reward for active minters would be closer to 5% per year. However, the problem with this scheme is that minters would try to game the system and only mint when minting participation is low. Thus, we came up with RFC-0018, which yields similar results, but keeps the reward calculation simple and prevents gaming of the algorithm. You can read more about the change here.
Long story short, the network will reward active minters more, while keeping the overall inflation around 1%.
Accompanied with an expected inflation drop from increasing PoW hashrate, overall monetary inflation will largely remain unchanged, and will be more stable.
Other changes are minor and do not change the behavior of the network. RFC-0017 is just a consequence of RFC-11, and it stops minters from going offline for longer than a year and coming back to mint. We did not see this as fair, so the coinage counter is reset after a year now. Limiting coinage disincentivizes extremely long term periodic minting, thereby making continuous minting more attractive.

Large-scale updates of Tkeycoin. What’s next? — listing on the crypto exchange. Are you with us?

Large-scale updates of Tkeycoin. What’s next? — listing on the crypto exchange. Are you with us?

https://preview.redd.it/ojtx6mauve151.png?width=700&format=png&auto=webp&s=8dd727076d495d4b624a307775e64ae83ce31c76
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/.

https://preview.redd.it/63a1cmdwve151.png?width=700&format=png&auto=webp&s=0a064bff4acd1c1e3171f2c72ff79533b87aa3e1

Full localization

Already today the official website tkeycoin.com available in 5 languages: Russian, English, Korean, Chinese (Simplified), Chinese (Traditional).

https://preview.redd.it/xbiodqixve151.png?width=700&format=png&auto=webp&s=dd81e99cb792d62a3ebb397d2181a2f1d0de5ac8
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.

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.

#Reddcoin ($RDD) Core Wallet Release 3.0.1 - PosV v2 SuperMajority Consensus Upgrade at 45.6% - Required Upgrade

Reddcoin (RDD) Core Wallet v3.0.1 - January 09, 2020
Version 3.0.1 is the official release version of Reddcoin Core. It is available for download at Reddcoin Core's Github repository here: https://github.com/reddcoin-project/reddcoin/releases/tag/v3.0.1
This release features PoSV v2.supermajority activation and new staking ruleset (and minor misc fixes). v3.0.1 is still not yet MacOS Catalina compatible. We are still working and should have that fix issued very soon. Sincere apologies to our Mac-using ReddHeads.
It is particularly important that all users upgrade, as once PoSV v2 is enforced, version 4 blocks will be rejected from the network entirely.
Therefore v3.0.1 is a "strongly recommended" update for all users. Note: If you have already installed v3.0.0, this upgrade is not required. If you have not yet upgraded from v2.0.x or earlier, this is a REQUIRED upgrade. Please install the newest version v3.0.1 to avoid losing functionality during supermajority activation of PoSV v2.
Reddcoin Core version 3.0.1 is now available from: https://github.com/reddcoin-project/reddcoin/releases Release Notes are available here and replicated below in this announcement: https://github.com/reddcoin-project/reddcoin/blob/mastedoc/release-notes.md
This is a new major version release of Reddcoin.
Previously, the original and subsequent versions of Reddcoin were taken from a fork of the Litecoin code base.
With the release of Reddcoin V2.0.0, the code was based directly from a fork of Bitcoin. This allows for better source control and feature implementation from upstream changes into the future
With the release of Reddcoin V3.0.0, the PoSV stake reward has been improved to allow for a target 5% network growth, in process re-incentivizing individual network stakers and providing for integrated dev support.
Upgrading to this release is strongly recommended and required for continued operation. Once a supermajority of 90% is reached, old wallets will no longer accept the new v5 blocks.
Please report bugs using the issue tracker at github:
https://github.com/reddcoin-project/reddcoin/issues
How to Upgrade
If you are running an older version of Reddcoin, shut it down. Wait until it has completely shut down (which may take a few minutes for older versions). Run the installer (on Windows) or just copy over /Applications/Reddcoin-Qt (on Mac) or reddcoind/reddcoin-qt (on Linux).
Start wallet. All done!
Reddcoin v3.0.0 introduced an updated PoSV method to better distribute staking rewards and target a overall 5% network growth. Staking and relay policy enhancements 
To implement PoSV v2, Reddcoin Core's block templates are now for version 5 blocks only. When PoSV v2 consensus (Supermajority 9000/10000) is reached, only v5 blocks will be accepted by the network.This equates to approximately 90% of blocks being generated over 1 week period. Status at any time may be viewed in node debug.log

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.

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.

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.

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.
