Bitcoin History Part 18: The First Bitcoin Wallet

weird behavior of electrum+bitcoin-qt

past week installed the new plugin that allow me to connect my electrum wallet to bitcoin-core, i use a hardware wallet and worked like a charm.
Then today was updating the node and used bitcoin-qt instead of bitcoind and when was waiting suddendly i see some text in the gui where it says "recent transactions", and a lot of transactions where there.
Then was like WTF happened here, someone stole my btc?, or installed a compromised version of electrum(i use archlinux and install from the repos). Why some transactions where there, i neved imported my wallet to bitcoin-gui.
Inmediately deleted the wallet.dat and did the same in electrum, but my question is:
Was something imported into bitcoin-qt?, all my history was redeable from the gui, i never imported into bitcoin-qt, and as far i know the seed never leave the hardware wallet.
This is normal?, at least all my funds are still there but im really worried.
PS: everything happened with my hardwallet unplugged.
TL:DR: Connected my cold wallet to electrum(connected to bitcoind) past week, never to bitcoin-qt, today opened bitcoin-qt and all my history of transactions from my cold wallet(unplugged) was there(bitcoin-qt), is this normal?.

Old Mining Contract - Reddit Sleuths Needed

Dear Famed Reddit Users,
I apologise in advance if I waste anybody's time here however I need suggestions on whether I can establish if I received a payment from a mining contract I took out in 2013.
Back in July 2013 I bough a Bitcoin mining contract from a website called bitcoinfrenzy.com. I paid $49 for "1 GH/s Bitcoin Mining Power – 1 Year Contract (#1GH001) "
This website no longer exists and it may have been a scam as I was quite flush back then so I bought the contract and thought no more of it.
After the initial purchase email in July 2013 I heard no more until November 2013.
13 November 2013 - Newsletter email stating: "After a long struggle Mining is started for July to till date customers . The order status for all paid orders will be updated within 48 Hours . And we will update"
16 November 2013 I have an email stating that the order had been processed
22 November 2013 Email stating that payouts have been made from wallet address 1LKpQYvMCyfa5AwD8KrDknhjGfP87xWsVN
No further emails after this point.
When I check the blockchain for this address I can see coins were sent to multiple addresses on 22 November 2013.
I do not know what wallet address I provided to bitcoinfrenzy for receipt of any payout.
I did create a wallet on blockchain in May 2013. I have accessed this wallet and there is no transaction history showing.
I have an old version of bitcoin-qt on an old hard disk drive which has a wallet.dat file created April 2013. I have been unsuccessful when trying to load this wallet.
I have all hard drives/laptops from 2013 and since.
Views on: Am I wasting my time here? I s there anything else I can search my hard drives for? How can I access my old wallet.dat (and none of the results I've found while searching have worked).
NB if one of the receiving addresses from the payout belongs to me the coins will be unspent, there will be no transactions after 22 November 2013 and there may not be any other transactions prior to this.
Thanks for reading

WALLETS, SETUP GUIDES & SNAPSHOTS
Just a reminder for the community and also for any new members, we have added a Wallet Setup Guides page, which takes any first time user of Mousecoin step-by-step through the process of installing their Mousecoin wallet and getting it online. The guide uses the latest blockchain snapshot found on the Wallet Downloads Page in the example explanation meaning that all new members of the Mousecoin community will be able to get their wallets online faster as the sync time should be minimal. We will be updating the blockchain snapshot at least once every month to ensure that people have access to the most up to date blockchain info. The latest blockchain snapshot was performed on the 1st June 2020.
The wallet version is currenty V1.0.0.0, with future releases of the Mousecoin wallet coming soon
If you are new to crypto currency or just after a bit of guidance setting up the Mousecoin wallet, check out our Wallet Setup Guides

POS & STAKING
In the last month we asked the community if they would be interested in being a part of a Community Staking Pool. After investigations into this finding security flaws in most platforms, as well as the lack of interest from members of the community we have decided to not go ahead with the Community Staking Pool. While we understand that there are members of the Mousecoin Community that are unable to stake themselves for whatever reason, and that there are a number of staking platforms that offer pool staking for MIC3 to help these people stake, we will not officially be supporting any staking platforms. We ask all Community members using these or thinking about using these to keep in mind that any MIC3 hosted on these platforms is not in their wallets, and therefore not controlled by them. Do proper investigations into any platform that you use for this as there is always the possibility of loss. We encourage all members of the Mousecoin Community to stake from their own wallet (where possible) as this helps us to secure the network. If you need help setting up your wallet, go to our Wallet Setup Guides page for step-by-step guides on setting up your Mousecoin wallet.
MOUSECOIN FAUCETS
We have updated the Mousecoin (MIC3) Faucets Page:
To make things clearer and we will be adding more faucets soon!
EXCHANGES
Last month we saw the edition of the USDT/MIC3 pair to nanu exchange. In our efforts to increase exposure of Mousecoin, we are still attempting to list on both ATAIX and Unnamed.Exhchange.
ATAIX We have risen to 18th position in the voting list on ATAIX, but we still need your votes. Remember you can vote every 24 hours for this listing, and you can share in 125,000,000 MIC3
📷
Unnamed.Exhchange The exchange listing for Unnamed.Exhchange is 0.05 BTC. For anyone unfamiliar with the exchange there are two ways that you can donate to the listing:
1. If you are already a member of, or wish to be a member of Unnamed.Exhchange (and why wouldn’t you), you can put funds towards our listing by tipping us through the trollbox (Mousecoins). If you wish to be a member of Unnamed.Exhchange, you can register here: https://www.unnamed.exchange/Login/Register
2. You can also donate to the listing fee through the following addresses: BTC – bc1qmaqzhfqcw0urva0rtgfz5qvq4rw7kdnp6j7754 LTC – ltc1qc775eeftdde2jrevnyukrd2w9853jy5gmtv6rn DOGE – DEnBpriaFnKiNeBv6Q7MVxMg5hLv5urQFg UTIP – AUTyu2JhGAaCkM3KAmeBopto2bNBchNJfE
If you would like to donate in another crypto available on Unnamed.Exhchange, we have opened up the chat on the Discord channel HERE to assist with this. Please request the address and we will provide it for you. ANY AND ALL DONATIONS ARE WELCOME!! This is a good exchange and getting a listing her should help lift the profile of MIC3.
We will be reporting balances to the discord channel https://discord.gg/cYuA8FA
COMMUNITY FUND
📷
In the last month the Community Fund has undergone a huge amount of change. We have completely moved all of our remaining balances away from 4Stake, with the MIC3 going to the Community Fund MIC3 account and the remaining crypto’s towards out listing on Unnamed.Exhchange. The Community Fund page on the website has also been updated to reflect all of the changes. It is an exciting time for the Community Fund as we have now reached a balance that will sustain itself. This is why we have introduced the Community Member payment, and are able to sustain the faucets we have on https://erex.io/freecoin/ and in the Phoneum Games. There is still more to come!

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.

Features

Android

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! – Groestlcoin EasyVanity 2020

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).

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.

such beginner shibe thread wow how to get coin

 how to shibecoin v rich in minutes much instruct so simple any doge can do 

START HERE

UPDATE 1/21/14: I'm not updating this guide anymore. Most of the steps should still work though. See the wiki or check the sidebar for updated instructions.
Before you do anything else, you need to get a wallet. Until there's a secure online wallet, this means you need to download the dogecoin client.
Now open the client you just downloaded. You'll be given a default address automatically, and it should connect to peers and start downloading the dogechain (aka blockchain in formal speak). You'll know because there will be a progress bar at the bottom and at the lower right there should be a signal strength icon (TODO: add screenshots).
If you've waited 2 or 3 minutes and nothing is happening, copy this:
maxconnections=100 addnode=95.85.29.144 addnode=162.243.113.110 addnode=146.185.181.114 addnode=188.165.19.28 addnode=166.78.155.36 addnode=doge.scryptpools.com addnode=doge.netcodepool.org addnode=doge.pool.webxass.de addnode=doge.cryptopool.it addnode=pool.testserverino.de addnode=doge.luckyminers.com addnode=doge.cryptovalley.com addnode=miner.coinedup.comdoge addnode=doge.cryptoculture.net addnode=dogepool.pw addnode=doge.gentoomen.org addnode=doge.cryptominer.net addnode=67.205.20.10 addnode=162.243.113.110 addnode=78.46.57.132 
And paste it into a new text file called dogecoin.conf, which you then place into the dogecoin app directory.
Now restart your qt client and the blockchain should start downloading in about 1-2 minutes.
Once it finished downloading, you're ready to send and receive Dogecoins!

GETTING COINS

Decide how you want to get Dogecoin. Your options are:
I'll go into detail about each of these. I'm currently writing this out. I'll make edits as I add sections. Suggestions are welcome.

MINING

Mining is how new dogecoins are created. If you're new to crypto currencies, read this. To mine (also called "digging"), a computer with a decent GPU (graphics card) is recommended. You can also mine with your CPU, but it's not as efficient.

GPU MINING

These instructions cover only Windows for now. To mine, you'll need to figure out what GPU you have. It'll be either AMD/ATI or Nvidia. The setup for both is approximately the same.

Step One: Choose a pool

There's a list of pools on the wiki. For now it doesn't really matter which one you choose. You can easily switch later.
NOTE: You can mine in two ways. Solo mining is where you mine by yourself. When you find a block you get all the reward. Pool mining is when you team up with other miners to work on the same block together. This makes it more likely that you'll find a block, but you won't get all of it, you'll have to split it up with others according to your share of the work. Pool mining is recommended because it gives you frequent payouts, because you find more blocks. The larger the pool you join, the more frequent the payouts, but the smaller the reward you get.
Over a long period of time the difference between pool and solo mining goes away, but if you solo mine it might be months before you get any coins.

Step two: Set up pool account

The pool you chose should have a getting started page. Read it and follow the instructions. Instructions vary but the general idea is:
When you're done with this, you'll need to know:

Step three: Download mining software

For best performance you'll need the right mining software.
Unzip the download anywhere you want.

Step four: Set up miner

Create a text file in the same folder as your miner application. Inside, put the command you'll be running (remove brackets).
For AMD it's cgminer.exe --scrypt -o stratum+tcp://: -u -p
For Nvidia it's cudaminer.exe -o stratum+tcp://: -O :
Substitute the right stuff in for the placeholders. Then on the next line of the text file type pause. This will let you see any errors that you get. Then save the file with any name you want, as long as the file extension is .bat. For example mine_serverName.bat.

Step five: Launch your miner

Just open the .bat file and a command line window should pop up, letting you know that the miner is starting. Once it starts, it should print out your hash rate.
If you now go to the pool website, the dashboard should start showing your hashrate. At first it'll be lower than what it says in the miner, but that's because the dashboard is taking a 5 minute average. It'll catch up soon enough.
NOTE: A normal hashrate is between 50 Kh/s up to even 1 Mh/s depending on your GPU.

You're now mining Dogecoins

That's it, nothing more to it.

CPU MINING

CPU mining isn't really recommended, because you'll be spending a lot on more on power than you'd make from mining Dogecoin. You could better spend that money on buying Dogecoin by trading. But if you have free electricity and want to try it out, check out this informative forum post.

Trading

Trading has been difficult so far, but Dogecoin just got added to a few new exchanges. If you don't have a giant mining rig, this is probably the best way to get 100k or more dogecoins at the moment. I'll write up a more complete guide, but for now check out these sites:

Faucets

Faucets are sites that give out free coins. Usually a site will give out somewhere between 1 and 100 Dogecoin. Every site has its own time limits, but usually you can only receive coins once every few hours, or in some cases, days. It's a great way to get started. All you do is copy your address from the receive section of your wallet and enter it on some faucet sites. Check out /dogecoinfaucets for more. If you go to each site on there you might end up with a couple hundred Dogecoin!

Begging

This method is pretty straightforward. Post your receiving address, and ask for some coins. Such poor shibe. The only catch is, don't do it here! Please go to /dogecoinbeg.

Tips

At the moment there are two tip bots:
Other redditors can give you Dogecoin by summoning the tip bot, something like this:
+dogetipbot 5 doge
This might happen if you make a good post, or someone just wants to give out some coins. Once you receive a tip you have to accept it in a few days or else it'll get returned. Do this by following the instructions on the message you receive in your inbox. You reply to the bot with "+accept". Commands go in the message body. Once you do that, the bot will create a tipping address for you, and you can use the links in the message you receive to see your info, withdraw coins to your dogecoin-qt wallet, see your history, and a bunch of other stuff.
As a bonus, so_doge_tip has a feature where you can get some Dogecoins to start with in exchange for how much karma you have. To do this, send the message "+redeem DOGE" to so_doge_tip. You'll need to create a tipping account if you don't have one.
If you want to create a tipping account without ever being tipped first, message either of the bots with "+register" and an address will be created for you.

[Midnight Monero] Interactive menu-based console UI for Monero node and wallet?

So, Bitcoin has a default GUI wallet made in Qt. Most other BTC clones have a wallet that's a forked version of Bitcoin Core. Monero and CN coins in general are different because they have a working CLI wallet. that is actually quite useable in interactive mode. However, it doesn't provide the usefulness of a full-featured GUI client.
There are GUI clients for Monero, Bytecoin, Masari, etc. But I've noticed that they're all to cumbersome and don't provide as much info as you can get from a CLI. But in a CLI you have to constantly type in commands in full text. There's no command history, keyboard shortcuts, or menu interface.
My question is, has anyone yet tried to write an interactive ncurses-like interface for Monero/CN Wallet? Something that looks like htop, gnuit, midnight commander, cmus, or a similar interface that tries to look like a GUI, while keeping speed, keyboard usability, and low CPU overhead of a console app?
I'd very much like to have my wallet residing in a tmux pane, showing balances, txes, and a window which displays state of the blockchain sync, network statistics, mempool size... all neatly organized. When you SSH into your node, you wouldn't have to type in any commands, just see at a glance what's going on.
I mean, look at this sexy IOTA node interface in interactive mode.
If no one has ever done anything similar, then maybe I can help. Is there enough docs on Monero github explaining how to API with a daemon and a wallet?

[ELI5] Extracting Privkeys from QT/Core

We have a constant stream of people coming back after abandoning Dogecoin and the sub in 2014 when the price fell. These people all have old versions of QT and are now basically trying to recover their coins, presumably to cash out and abandon us again. This is causing strain for the network, as far more people are trying to leech blocks than seed them.
The thing is, none of this is necessary. Especially if you're just going to dump coins. With resources such as https://coinb.in/#settings all you need are your private keys, and you can create, sign and broadcast transactions yourself. No client required, let alone one as resource-hungry as QT.

"So, how do I get my keys?"

First of all, lets talk about data management. The overwhelming majority of coins are not lost through theft, especially direct theft of wallets (as distinct from wholesale thefts/scams/implosions like Moolah, GAW, MtGox, Cryptsy, and even our own beloved Dogetipbot). Most coins are lost because people forget about their wallets and do silly things like reformat hard drives, lose passwords and so on.
So, everyone should have a wallet list. Here is a sample bit of HTML that gives you a page with two columns of wallets, one for local wallets you would withdraw coins to, the other the third-party wallets you would deposit coins to third parties through (do note that many services use temporary addresses generated for deposits which expire after 24h or so). A page like this is how I manage my 100+ wallets, and I have copies on my network and hidden online. Such a page makes it easy to at least keep track of all your wallets, for a trivial amount of work to set up.
 
 Sample - Twitter Fr DFXXz9gq3WkgJaHn9tXRChMhFQcwm4Y251 To DByYgzd4ec5Ku9vPag8XqoBfyRpsoj8Xs3 @TipDoge Sample - Backslash Fr DSDyv83VC1QtEnmJ4ATKFn5Sw3iC12VLmX To D9MsxSyJe5Mq7fWFRpC7zQQt1gexHccN4w Backslash To DJ3GL68kw8vh99RvxnEmQKE8A3cWRoEEqo Backslash Faucet Sample - Block.io To DE5QamzWVnxK2HmCS61cUsrn9iwgTArunU Block.io 

"OK, great, so now I have a list of my wallets. Now what?"

Now you're going to need the private keys for each of those wallets. Obviously you're not going to store these in a public place though. So you will need a separate file, which can just be plain text. Copy each of those addresses into it.
Now go ahead and fire up QT. If you haven't synced it in 3 years, its going to take forever, but that doesn't matter. You don't actually need the blockchain for this, so you don't have to wait for it to catch up.
Open up the console which is in the Help menu. Then give the command dumpprivkey with the wallet address you want the key to. Then use the up-arrow key to bring that command back, replace the address with the next one, and keep going until you have them all.
It will look something like this:
 13:05:18 Welcome to the Dogecoin RPC console. Use up and down arrows to navigate history, and Ctrl-L to clear screen. Type help for an overview of available commands. 13:11:06 dumpprivkey D9xDcRthB6XP4vRGqiyKdDfVJ7CWhYuBBi 13:11:06 6KEcssuq1wWUrFVmMF8yDxHuAdQMiRezz53zDxADLmyoXnix7iM 13:12:00 dumpprivkey DUDARNrGHVTFcCgriwRWgDQJPKDuDQr9jg 13:12:00 6JNk6NNFZcr49fbsD2jcTfTxFLjJKq9DHQ5JU8CYeZ2Cz6JdKMY 13:12:25 dumpprivkey DG6xnwCT6BXePaySqU85XocobZmhbJczQH 13:12:25 6JNXFv95Mp9SzehHw9jojjdxHRNPeh77qCsRbaNwJZMp9MKCAu3 
Yes, those are real wallets. But don't bother trying to steal my coins, I just generated them on https://walletgenerator.net/ and they're empty.
That's basically it. All you need to do is add some descriptions of what the wallets are, pretty up the format to your liking, and save copies in multiple, secure places, including printed out.

Remember, if you lose your keys, OR someone else sees them, you lose your coins!

If those were my real wallets above, you could use the keys and spend my coins. So obviously, don't let anyone else, especially annoying little brothers, get their grubby hands on them. But also make sure they can be discovered if anything happens to you. That's why the printed copies... nobody is going to go trolling through your porn or warez collection on the offchance there's something valuable in there. But they will look in your safe or wherever you store other important documents. Just be sure to leave a note as to what they are and how to use them. Remember the woman who came here a couple years ago who had found a USB stick with 110 BTC in a locked wallet.dat on it from her dead husband? I sometimes wonder if she ever got the money. Don't be her. Or him.

"OK, great. Now I have my keys. What now?"

Well, you can spend coins using https://coinb.in/#settings from any wallet you have the keys to. First step is to choose the network. Dogecoin (mainnet) obviously. Then go to Transaction in the +New menu. Enter your address and hit the Load button. It will pull in the first 100 transactions. Now enter the address to pay, and the amount.
Note the Transaction Fee box!
You want this amount to be zero. Depending on whether you're moving coins to another of your wallets to consolidate them (a very good idea.. go read the UTXO ELI5, which you will find a couple pages into https://www.reddit.com/dogecoin/comments/4yts6h/start_here_for_much_wallet_wow/ - Yes, I'm going to make you work for it, cos there's tons of useful stuff there you need to know), or paying someone else, you may want to select which inputs to use.
Once you're happy with the transaction, go ahead and submit it. You will now get a block of text, which is the raw, unsigned transaction. Copy this. Go to the Sign tab. Paste it. Add your private key and Submit to sign it.
After a little bit, you will get a signed transaction. Copy it. Go to the Broadcast tab, paste it and hit Submit.
That's it. It should go into the next block in a minute or two. Yes, even without paying a mining fee. Our network is so lightly loaded that there are no contention issues like the Bitcoin people have to put up with.

"That's it? So why do I need QT?"

You don't. The process above is all that's involved in spending coins. Everything else is window dressing. So there is no need to run QT, or any other client. Oh, and since you can download the site and run it locally (mostly offline), there is no security issue beyond the usual keyloggers/spyware that can compromise anything. And by knowing how to do this, you are much better protected from accidental loss than someone who blindly trusts black boxes they don't understand.
Oh, one final thing... if you really want to help the network by seeding rather than leeching, go ahead and run a full node. Instructions are in that link above. AND you may want to help seed the bootstrap file torrent from a couple of days ago. Just because YOU don't need it, doesn't mean others don't, right?

Groestlcoin Release September 2018

Introduction

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

What's been Happening?

GRSPay Released

We are so excited for this, that it has it's own separate reddit thread. Head over there now at https://www.reddit.com/groestlcoin/comments/9ikr5m/groestlcoin_releases_grspay/? to see more on this!
https://www.melis.io/assets/logo-navbar-4b6f0d372f15b2446d3fa4c68f346e4fb08ee113941186cee58fd6135f3f8b7d.svg

Melis Wallet

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

How Melis Works?

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

Integrated into Blockchain Financial

What is Blockchain Financial?

Blockchain Financial is a set of web based services for individuals and companies that want to make things happen with the Cryptocurrencies Ecosystem. - For those that don't know anything about cryptocurrencies, we offer tools that will let them receive, send and operate with an assortment of coins. - For those that are already riding the wave, we offer tools that will let them do all those things that they weren't able to do.

Blockchain Financials mission

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

More information from Blockchain Financial

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

Groestlcoin Core v2.16.3 - Please Update ASAP

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

What's new in version v2.16.3?

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

The Technicals

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

You can even generate multiple keys with the same prefix and leave it on overnight whilst your CPU or GPU collects and stores these addresses locally.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then Groestlcoin EasyVanity is the right choice for you to create a more personalized address.

Features

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

IRC Log from Ravencoin Open Developer Meeting - Aug 10, 2018

[16:01] <@Wolfsokta> Todays topics: DGW implementation, segfault, Q&A, feedback on IRC
[16:01] <@Wolfsokta> Just to set the stage here, this is a developer meeting where developers that have contributed source code to the Ravencoin project can meet and chat about items they are working on. Please be respectful to one another. For the sake of staying on target, please limit interactions to questions and comments on code or projects that you are working on. Any time left over at the end can be opened up for general Q&A.
[16:02] <@Wolfsokta> FYI - I'm RavencoinDev, and lets get started.
[16:03] <@Wolfsokta> @Tron, can you talk about where we are at with DGW on testnet and mainnet?
[16:03] <@Tron> Sure.
[16:03] can someone volunteer to take notes and post also?
[16:03] <@Tron> We are building binaries that will activate DGW-180 at block 338778
[16:04] <@Tron> It looks back 180 blocks to calculate the diff.
[16:04] I will copy the text from the meeting into a file that can be archived later. I can also make summary notes after like BTC core does.
[16:04] I'll save a log of the whole meeting and can post it on the subreddit thread.
[16:04] <@Wolfsokta> We have setup testnet4 in order to test the new binaries.
[16:04] great
[16:05] <@Wolfsokta> We plan to release the binaries later today.
[16:05] @Tron have you looked into the timestamp attack concerns of DGW?
[16:05] https://github.com/zawy12/difficulty-algorithms/issues/30
[16:06] <@Tron> Yes. And for that reason, we've tightened up the timestamps that will be accepted for valid blocks.
[16:06] <@Tron> Moved from 2h to 12 minutes.
[16:06] nice
[16:06] Oh wow okay
[16:06] <@Tron> Its also the reason we went from 60 blocks (lookback) to 180 blocks.
[16:07] why would 2h ever be acceptable? lol
[16:07] 2h was originally used for daylight savings shenanigans I believe
[16:07] <@Tron> It was from bitcoin, and it factors in clock skew, and variance in finding blocks on 10 minute intervals, and block propagation time.
[16:07] makes sense
[16:08] what about the segmentation fault when reindexing?
[16:08] any fix yet?
[16:08] @Tron 12 minutes seems to be pretty small window for clock skew
[16:08] I assume it was chosen due to 1/10th scaling from BTC?
[16:09] <@Wolfsokta> Not yet ruski, we'll cover that in a bit.
[16:09] <@Tron> We did divide existing by 10.
[16:10] <@Wolfsokta> Any further questions about DGW on testnet or on mainnet?
[16:10] What block is it activating on mainnet?
[16:10] <@Wolfsokta> 338778
[16:11] And will there be the need to update binaries twice (for DGW fork and asset layer fork)?
[16:11] <@Tron> We are activating DGW by block height because headers sync first, and the BIP9 activation flag sets a flag, and we need to look at either block height or version to know which diff algo.
[16:11] <@Wolfsokta> Calculated to be near the end of the month so we have some time with DGW on testnet.
[16:11] Someone on discord asked this a while back, but why Was DGW chosen over something like digishield or anyother algo
[16:11] <@Tron> And block version can be changed (tampering) and still make it on the chain.
[16:12] Binaries will need to be updated as more asset layer stuff get completed and tested. Not by the end of the month though.
[16:12] <@Tron> We looked at DGW and LWMA. LWMA has a lot of constants that must be tuned right.
[16:13] <@Tron> We were impressed with the amount of work on LWMA to analyze how it responds, but it wasn't straightforward to understand the nuances of how/why it works.
[16:13] zawy was in the #development channel on Discord. He's an expert on DAAs. I'm sure he would help with tuning LWMA if you asked.
[16:14] <@Tron> Either will be much better that what we have. Even at the extremes, it will adjust smoothly.
[16:14] Are there any issues or comments on the DGW code that should be addressed?
[16:14] @devs in general
[16:15] <@Wolfsokta> Thanks @brianmct, we did look extensively at the DGW code to ensure we weren't going to see the same issues that happened to Verge.
[16:16] so i guess you would have to make way more blocks with false timestamps to be able to exploit our version of dgw right?
[16:16] because of the 12 minute timestamp thing?
[16:16] <@Wolfsokta> With X16R, and with the changes Tron talked about we feel confident that this will address the swings without being able to be exploited.
[16:17] nice
[16:17] @russki Yeah, pretty much.
[16:17] verge is a different type of situation - but overall asics and mining are a risk always
[16:18] <@Wolfsokta> Okay, anything else on the difficulty targeting change?
[16:19] <@Wolfsokta> Cool, blondfrogs wanted to talk about subassets that were added.
[16:19] ooh yeah i saw those github commits
[16:19] looking good
[16:19] We also want to let everyone know that you can now create sub assets with the new binaries that will be posted soon. You can create these subassets using the issue rpc call. Qt will be built shortly. This will allow users to make an asset PARENT
[16:20] <@Wolfsokta> Basic overview. If you own an asset you can create sub-assets by including a '/
[16:20] nice
[16:20] And then make any of the following PARENT/A PARENT/B .... PARENT/Z
[16:20] <@Tron> We'll post a FAQ on assets later today.
[16:21] <@Wolfsokta> And it only is 100 Raven for a subasset
[16:21] on testnetv4 it still says asset activation status: waiting
[16:21] why?
[16:21] <@Tron> Yep, it needs to be voted in.
[16:21] <@Wolfsokta> We wanted to test the BIP9 activation process again as well. The more testing the better.
[16:21] We wanted to make sure that we follow the same process the Mainnet is going to go through.
[16:21] ok nice
[16:22] <@Wolfsokta> Any questions about subassets?
[16:23] are they unique?
[16:23] <@Tron> No
[16:23] <@Wolfsokta> Yes, they behave the same way as a normal asset, just live under an owned asset.
[16:23] <@Tron> Maybe I misunderstood the question. Unique with parent.
[16:23] Each subasset can have their own number issued? So PARENT/A can have 1,000 and PARENT/B can be 50?
[16:23] yes
[16:23] oooh ok that makes more sense
[16:23] <@Wolfsokta> Exactly thanks traysi
[16:24] <@Tron> And, not the same thing as "Unique Assets"
[16:24] <@Wolfsokta> The individual unique asset support is included in an upcoming phase.
[16:25] Moving onto the Segfault issue ----------------------->>>>>>>>>>> SEGFAULT
[16:25] Are we able to changes the properties of subassets after they have been created? Or is something like that specified when creating them?
[16:25] <@Tron> Yes
[16:25] can sub-assets be reassigned to other addresses while retaining control of the parent asset elsewhere?
[16:25] So basically it has all the features of a normal asset, but live under an asset's top-level namespace?
[16:25] satoshi corbie @russkidooski
[16:25] So basically it has all the features of a normal asset, but live under an asset's top-level namespace?
[16:26] <@Tron> Sub-assets are identical to assets after creation.
[16:26] <@Tron> Just cheaper to create, and in your "owned" namespace.
[16:26] Okay cool
[16:26] will subassets eventually have a unqiue tag? eg ASSET/SUB:1
[16:26] We have found an issue with our testnet binaries and are still looking to the issue. The issue presents itself when a user performs a reindexing of the chain. We think we have pinpointed the where the problem is and are currently working a fix. This fix will be out shortly.
[16:26] plan is to make default reissue=true and units=0 and allow increase in units on reissue
[16:26] How much is it going to be for a sub-asset?
[16:27] 100
[16:27] <@Wolfsokta> Okay, let's now focus on the SegFault issue that was discovered by Under.
[16:28] do you know what the issue was?
[16:28] <@Wolfsokta> It seems to be a build problem with the boost library.
[16:28] Still looking into though. :)
[16:29] <@Wolfsokta> We have been able to reproduce it on linux internally with 2.0.3
[16:29] yea i get the same issue on windows 10
[16:30] I saw a Bitcoin thread a while back about the seg fault error. I had it because I had conflicting versions of BDB
[16:30] static compiled on ubuntu 18.04
[16:30] <@Wolfsokta> We really appreciate you guys pulling down master and helping test.
[16:30] @Trap we will look into that also
[16:30] no problem, im just curious lol
[16:32] <@Wolfsokta> We haven't been able to build a windows version that doesn't have the segfault issue.
[16:32] <@Tron> We're dropping Windows support ;)
[16:32] lol
[16:33] Just finished setting up a new Windows test environment so we can test and validate the solution as we are working on it.
[16:33] The bdb issue is a known issue that has been around for some time. We are pretty certain it is a boost library issue, and are working quickly to get a windows build that fixes the issue.
[16:34] what did you guys do to fix the linux version?
[16:34] Once we have binaries for all supported platforms ready, hopefully tonight. No promises. We will make an announcement
[16:34] The issue has been fixed on Linux and Mac though?
[16:34] (oops sorry already answered)
[16:34] <@Wolfsokta> If anybody else gets there first with Windows please let us know what you found.
[16:34] Built the binairies on a Ubuntu 16.04 box.
[16:34] that was it?
[16:35] Yeah, we think so. 16.04 has boost 1.58 which seems to fix the issue. The build on 18.04 use boost 1.67 which seems to cause the issue.
[16:35] is there a boost 1.58 repo on 18.04?
[16:35] 18.04 used 1.65***
[16:36] I've built with boost 1.68 on arch Linux
[16:36] It worked
[16:37] wallet 2.0.x?
[16:37] @Trap, the issue is when -reindex is used.
[16:37] Oh sorry my bad
[16:37] Wallet 2.0.3
[16:38] <@Wolfsokta> For those that joined late we're discussing https://github.com/RavenProject/Ravencoin/issues/208
[16:38] 1 sec im going to boot into ubuntu and try compiling with 1.58 on 18.04
[16:39] Any other questions pertaining to the segfault?
[16:40] <@Wolfsokta> Alright, thanks everybody. Before we start the Q&A I would like to get some quick feedback on using IRC for this meeting.
[16:41] If we're going to use IRC we should take some measures to at least hide people's IPs when they join
[16:42] Yea. It is very hard to read this back.
[16:42] Also no message history
[16:42] If you disconnect and reconnect
[16:42] <@Tron> I'll throw in a vote for Discord.
[16:43] <@Wolfsokta> If you use a decent IRC client instead of the website it's not bad.
[16:43] Some of us used a VPN before we connected to IRC
[16:43] If needed we can restrict channel to Developer roles, etc for the developer meeting and open it up for general Q&A
[16:43] https://www.strawpoll.me/16247952
[16:43] poll
[16:43] Make a discord when only mods can submit links
[16:43] Where*
[16:45] Discord won the poll 5 to 2
[16:45] <@Wolfsokta> There are also a lot of IRC tools that can be used to track the meetings.
[16:45] we know
[16:46] <@Wolfsokta> We also want any developer to be able to speak.
[16:48] <@Wolfsokta> We're open to try Discord next week.
[16:48] <[kai]> perhaps you could even get a feed from this irc to discord?
[16:49] <[kai]> a feed would enable discordians to view the chat, but only contribute if they take the extra steps to come here.
[16:49] <@Wolfsokta> That's a good idea kai... Has anybody seen that working?
[16:50] <[kai]> https://github.com/reactiflux/discord-irc
[16:50] <[kai]> im sure you could make this a one way deal.
[16:51] <@Wolfsokta> I like that idea, let's try that for next week. So we'll meet here in IRC again, but it should be broadcast to Discord.
[16:53] <@Wolfsokta> Okay, we'll go with IRC next week with the broadcast to discord and re-visit for next week.
[16:54] <@Wolfsokta> Okay, let's do open Q&A for the next few mins.
[16:54] <[kai]> just a quickey, more for my curioisty, did you look at digishield?
[16:54] <[kai]> DGW solution seems solid.
[16:55] <[kai]> was just curious if it was one of the four solutions you looked at.
[16:55] <@Wolfsokta> Tron is answering... Any others Q?
[16:55] <@Tron> We briefly looked at Digishield, but our analysis was between DGW and LWMA.
[16:55] <[kai]> right on.
[16:56] <[kai]> cheers guys, see you next time.
[16:56] OPen the gates for the last 4 minutes for any other questions?
[16:58] <@Wolfsokta> Alright, thank you all for being here today and please join the development effort with us. If you have an idea, or a fix for an issue write it up and submit a pull request.
[16:59] <@Wolfsokta> Thanks again for all those that have contributed their time and effort to make Ravencoin successful. We have the BEST community.
[16:59] ^
6:59] You devs are pretty cool
[16:59] did the burn get discussed?
[16:59] <@Wolfsokta> Special thanks to Bruce, really glad you could make it with the short notice.
[17:00] <@Tron> Thanks everyone!

[Giveaway] [Part 7] [10x multiplier] We at the subreddit /r/dogeillionaires are giving away one million (Ð1,000,000) dogecoins!

This giveaway is now completed. Congratulations to all participants, thank you all for your great ideas, and stay tuned for the results of the Ð250,000 contest!
All contest winners will be contacted via PM when the panel has finished voting.
Welcome to the seventh and final part of these threads, where at you folks we throw a bunch of dogecoins! The first part we posted here, the second part here, the third part here, the fourth part here, the fifth part here, the sixth part here, and the seventh part we're posting now. This is the third special edition of our giveaway series. In this edition, we're posting not to /dogecoin but to /dogecoinbeg, where we will be giving back to the needy. In the spirit of this, all tips we would make that in threads 1 through 4 would be under Ð1000 will be multiplied by 10. This therefore very well may be the biggest giveaway in /dogecoinbeg history!
Without further ado, let's get to it!
Hey /dogecoinbeg!
We are /dogeillionaires, a subreddit for which membership qualification requires that you click here and prove you have ≥ Ð1,000,000. Unlike many of the meaner folks in the serious 1% of the offline world, we as the much sillier 1% of the Dogecoinverse like to redistribute our wealth and give back to the community! Back when the price of XDG was much higher than it is now, here's some of what we've done:
  • We've raised > Ð300K for excited biologist / Reddit celebrity Unidan's scientific research on crow movements
  • We've helped out behind the scenes to organize lots of stuff related to the Unidan initiative
  • We through these giveaways have generated two separate commitments from Unidan to Dogecoin
  • We're collectively responsible for around half a million coins reaching Doge 4 MMA
  • We've to ~Ð150K sponsored a shibe's brochure, paper wallet, and flyer contest frontpaged and stickied here
  • We've sponsored two giveaways, each one to the tune of > Ð100K
  • Our members have donated to numerous community charity initiatives
  • One of our members (not Moolah, but he has too!) has donated > Ð10,000,000 to such initiatives
  • We're collectively responsible for Ð84K of funds reaching the Doge 4 Water initiative
  • We've made donations to people who've lost coins to the insolvent Bitcoin exchange MtGox
  • We've helped to reimburse some of the shibes who fell victim to a tip-multiplying Ponzi scheme
  • We have a tipping mascot (this account!) which stops by threads to drop off tips and brighten days
  • We've organized, sponsored, and helped with paper wallet features for an upcoming version of dogecoin-qt
  • We've organized and are sponsoring the creation of a one-click P2Pool-based mining program
  • We started off a chain of tips that led to one shibe's medical bills being paid and their life being saved
True to the name of our subreddit, we're now giving away one dogeillion dogecoins!
Here's how this is going to work.
We're dividing this into a giveaway and a contest.
In the giveaway part, we will disburse Ð750K. In the contest part, we will disburse Ð250K.
We'll first talk about the giveaway part of this initiative.
FOR A SMALL TIP: Make a post that includes "Thanks, /dogeillionaires!" so we know you're not a bot.
FOR A MEDIUM TIP: Submit an idea that if put into practice could help Dogecoin succeed.
FOR A LARGE TIP: Declare a commitment ("I will...") to do something to help Dogecoin succeed.
The amount we donate to you with our small tips will be a consistent Ð20 Ð200. The amount we donate to you through our medium and large tips will be decided according to the interaction of metrics like:
  • The quality of your idea
  • The substance behind it
  • How workable it is
  • How unique it seems
  • The length of your post
  • The effort you spend on it
For commitments, we'll use similar evaluation criteria, and we'll be more likely to award you more coins if you present to us evidence to convince us you'll come through. Don't worry too much about not being fast: we'll be here a while!
If we've tipped you before, we may only tip you Ð20 Ð200 or skip over you the second time.
For the contest part, we will disburse Ð250,000 dogecoins over 20 people according to the following pay structure:
#1 - Ð100,000 #2 - Ð50,000 #3 - Ð25,000 #4 - Ð15,000 #5 - Ð10,000 #6 - Ð9,000 #7 - Ð8,000 #8 - Ð7,000 #9 - Ð6,000 #10 - Ð5,000 #11 - Ð4,000 #12 - Ð3,000 #13 - Ð2,500 #14 - Ð2,000 #15 - Ð1,500 #16 - Ð1,000 #17 - Ð500 #18 - Ð250 #19 - Ð150 #20 - Ð100 
The ideas and commitments that you guys and girls submit will be evaluated for the contest. What this means for you is if you submit what we determine to be the best idea or declare what we determine to be the best commitment, you have a chance of winning Ð100,000. Not only is this the case, but even if you don't win the Ð100,000, you may be one of many other people to win a prize! Both commitments and ideas are eligible, but a total of only 20 commitments or ideas will win.
Contest winners will be decided at a later date that has not yet been determined. You don't need to check in here to see if you've won - you'll be notified by us of that via Reddit PM!
A few of our notable sponsors for this contest, and the people without whom this would not be possible, are:
ijmolder93 - Ð200,000 (www.thecryptodepot.com Buy Anything* With Dogecoin!) maximumpanda - Ð197,385.63 echo85 - Ð100,000 (helped organize the format!) MostlyRegrets - Ð100,000 scrubsBscrubbin - Ð100,000 SpeakAlwaysTheTruth - Ð100,000 (ヽ༼ ^ °ᴥ° ^ ༽ノ) Terminative - Ð100,000 (http://i.imgur.com/dZgFPpm.jpg) aukust - Ð29,000 ithink4iDoge - Ð28,613.37 wbic16 - Ð25,000 
Thanks to them and thanks to all the others who donated as well! They are what make us what we are. Without them, we would be nothing, and it is to them that we all owe a debt of gratitude.
We at /dogeillionaires are committed to the success of Dogecoin, the circulation of crypto, the stimulation of the XDG economy, and the financial recognition of your novel ideas and good deeds.
Who knows - if an idea is good enough, perhaps in the future we'll even help fund it. :)
Let's get this started!

Blockchain online training

Blockchain online training

Blockchain originally blockchain, is a growing list of called blocks, which are linked using Each block contains a cryptographic hash of the previous block, and transaction data (generally represented as a Merkle tree root hash).

https://preview.redd.it/a1zwz5waty821.jpg?width=480&format=pjpg&auto=webp&s=b9b6d3f8953094e933597acfef463283f9066114

a blockchain is resistant to modification of the data. It is “an open, distributed ledger that can record transactions between two parties efficiently and in a verifiable and permanent way”. For use as a distributed ledger, a blockchain is typically managed by a peer-to-peer network collectively adhering to a protocol for inter-node communication and validating new blocks. for best blockchain training visit follow link
