Groestlcoin 6th Anniversary Release

Introduction

Dear Groestlers, it goes without saying that 2020 has been a difficult time for millions of people worldwide. The groestlcoin team would like to take this opportunity to wish everyone our best to everyone coping with the direct and indirect effects of COVID-19. Let it bring out the best in us all and show that collectively, we can conquer anything.
The centralised banks and our national governments are facing unprecedented times with interest rates worldwide dropping to record lows in places. Rest assured that this can only strengthen the fundamentals of all decentralised cryptocurrencies and the vision that was seeded with Satoshi's Bitcoin whitepaper over 10 years ago. Despite everything that has been thrown at us this year, the show must go on and the team will still progress and advance to continue the momentum that we have developed over the past 6 years.
In addition to this, we'd like to remind you all that this is Groestlcoin's 6th Birthday release! In terms of price there have been some crazy highs and lows over the years (with highs of around $2.60 and lows of $0.000077!), but in terms of value– Groestlcoin just keeps getting more valuable! In these uncertain times, one thing remains clear – Groestlcoin will keep going and keep innovating regardless. On with what has been worked on and completed over the past few months.

UPDATED - Groestlcoin Core 2.18.2

This is a major release of Groestlcoin Core with many protocol level improvements and code optimizations, featuring the technical equivalent of Bitcoin v0.18.2 but with Groestlcoin-specific patches. On a general level, most of what is new is a new 'Groestlcoin-wallet' tool which is now distributed alongside Groestlcoin Core's other executables.
NOTE: The 'Account' API has been removed from this version which was typically used in some tip bots. Please ensure you check the release notes from 2.17.2 for details on replacing this functionality.

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

Built with React Native, Moonshine utilizes Electrum-GRS's JSON-RPC methods to interact with the Groestlcoin network.
GRS Moonshine's intended use is as a hot wallet. Meaning, your keys are only as safe as the device you install this wallet on. As with any hot wallet, please ensure that you keep only a small, responsible amount of Groestlcoin on it at any given time.

ALL NEW! – HODL GRS Android Wallet

HODL GRS connects directly to the Groestlcoin network using SPV mode and doesn't rely on servers that can be hacked or disabled.
HODL GRS utilizes AES hardware encryption, app sandboxing, and the latest security features to protect users from malware, browser security holes, and even physical theft. Private keys are stored only in the secure enclave of the user's phone, inaccessible to anyone other than the user.
Simplicity and ease-of-use is the core design principle of HODL GRS. A simple recovery phrase (which we call a Backup Recovery Key) is all that is needed to restore the user's wallet if they ever lose or replace their device. HODL GRS is deterministic, which means the user's balance and transaction history can be recovered just from the backup recovery key.

ALL NEW! – GroestlcoinSeed Savior

Groestlcoin Seed Savior is a tool for recovering BIP39 seed phrases.
This tool is meant to help users with recovering a slightly incorrect Groestlcoin mnemonic phrase (AKA backup or seed). You can enter an existing BIP39 mnemonic and get derived addresses in various formats.
To find out if one of the suggested addresses is the right one, you can click on the suggested address to check the address' transaction history on a block explorer.

ALL NEW! – Vanity Search Vanity Address Generator

NOTE: NVidia GPU or any CPU only. AMD graphics cards will not work with this address generator.
VanitySearch is a command-line Segwit-capable vanity Groestlcoin address generator. Add unique flair when you tell people to send Groestlcoin. Alternatively, VanitySearch can be used to generate random addresses offline.
If you're tired of the random, cryptic addresses generated by regular groestlcoin clients, then VanitySearch is the right choice for you to create a more personalized address.
VanitySearch is a groestlcoin address prefix finder. If you want to generate safe private keys, use the -s option to enter your passphrase which will be used for generating a base key as for BIP38 standard (VanitySearch.exe -s "My PassPhrase" FXPref). You can also use VanitySearch.exe -ps "My PassPhrase" which will add a crypto secure seed to your passphrase.
VanitySearch may not compute a good grid size for your GPU, so try different values using -g option in order to get the best performances. If you want to use GPUs and CPUs together, you may have best performances by keeping one CPU core for handling GPU(s)/CPU exchanges (use -t option to set the number of CPU threads).

Groestlcoin EasyVanity 2020 is a windows app built from the ground-up and makes it easier than ever before to create your very own bespoke bech32 address(es) when whilst not connected to the internet.
If you're tired of the random, cryptic bech32 addresses generated by regular Groestlcoin clients, then Groestlcoin EasyVanity2020 is the right choice for you to create a more personalised bech32 address. This 2020 version uses the new VanitySearch to generate not only legacy addresses (F prefix) but also Bech32 addresses (grs1 prefix).

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.

Mega FAQ (Or: Please come here for your questions first)

Qbundle Guide (Step by step setup & Bootstrap) https://burstwiki.org/wiki/QBundle
1( I want to mine or activate My account. Where do find the multiple coins?
You only need 1, an outgoing transaction or reward reassignment will set the public key. Get them from:
https://www.reddit.com/burstcoinmining/comments/7q8zve/initial_burstcoin_requests/
Or (Faucet list)
https://faucet.burstpay.net/ (if this is empty, come back later)
http://faucet.burst-coin.es
Or
https://forums.getburst.net/c/new-members-introductions/getting-started-initial-burstcoin-requests
2( I bought coins on Bittrex and want to move to my new wallet, but can't. Why?
Bittrex will only send to accounts with a public key (not a Burst requirement) so see number 1 and either set the name on the account (IF you will not mine) or set the reward recipient to the pool. Either action will enable the account and allow for transfers from Bittrex.
3( I sent coins from Poloniex/anywhere to Bittrex and they don’t show up after a considerable time. Why?
You need to set an unencrypted message on the transaction, informing Bittrex which account to send the funds to (this is in the directions on Bittrex). Did you do this? Contact Bittrex support with all the details and eventually you will get your funds.
4( How much can I make on Burst?
https://explore.burst.cryptoguru.org/tool/calculate
Gives you an average over time assuming a few things like: Average luck/100% uptime/no overlapping/fees on pool/good plot scan time (<20 seconds) if you do not have all of these, you may not see that number.
5( If I use SSD’s would I make more money?
No, it’s 95% capacity and 5% scan time that determine success. More plot area = better deadlines = better chance of forging a block, or better rates from a pool.
6( What is ‘solo’ and ‘pool’ (wasn’t his name Chewbacca?)
Solo is where you attempt to ‘forge’ (mine) a block by yourself; you get 100% of the block reward and fees. But you only receive funds if you forge, no burst for coming in second place.
Pools allow a group of miners to ‘pool’ together their resources and when a miner wins, they give the pool the winnings (this is done by the reward assignment you completed earlier), it is then divided according to different percentages and methods and burst is sent out according to pool rules (minimum pay-out, time, etc.)
7( I have been mining for 2 days and my wallet doesn’t show any Burst WHY?
Mining solo: it is win-or-lose, nothing in between, and wining is luck and plot size. Pool mining: because it costs 1 burst to send burst, the pools have either a time requirement (every X days) or a minimum amount (100 burst +) so you need to research your pool. Some pools allow for you to set the limit (cryptoGuru and similar) to be met before sending
8( How do I see what I have pending?
On CryptoGuru, based pools, it’s the ‘Pending (burst)’ column, other pools, look for the numbers next to your burst ID. One is Paid and the other pending.
9( I’m part of a pool and I forged a block, but I didn’t recieve the total value of the block, why?
A pool has 2 basic numbers that denote the pay-out method, in the format ‘XX-XX’ (i.e. 50-50) The first number is the % paid to the block forger (miner) and the second is the retained value, which is paid to historic ‘shares’ (or, past blocks that the pool didn’t win, but had a miner that was ‘close’ to winning with a good submitted deadline)
Examples of pools:
0-100 (good for <40TB)
20-80 (30-80TB)
50-50 (60-200TB)
80-20 (150-250)
100-0 (solo mine, 150+ TB)
Please note that there is an overlap as this is personal preference and just guidance; a higher historical share value means a smoother pay-out regime, which some people prefer. If fees are not factored in, or are the same on different pools, the pay-out value will be the same over a long enough period.
10( Is XXX model of hard drive good? Which one do you recommend?
CHEAP is best. If you have 2 new hard drives, both covered by warranty, get the one with the lowest cost per TB (expressed as $/TB , calculated by dividing the cost by the number of terabytes) because plot size is KING,
11( How many drives can I have on my machine?
For best performance, you can have up to 2 drives per thread (3 on a new fast AVX2 CPU). So that quad-core core-2-quad can have up to 8 drives, but a more modern i7 with 4 cores + hyper threading can squeeze 8 * 3 or 24 drives. (Performance while scanning will suffer)
12( Can I game while I mine?
Some people have done so, but you cannot have the ‘maximum’ number of drives and play games generally.
13( Can I mine Burst and GPU mine other coins?
Yes, if you CPU Mine Burst.
14( I’m GPU plotting Burst and GPU mining another coin, my plots are being corrupted, why?
My advice is dedicating a GPU to either mining or plotting, don’t try to do both.
15( What is a ‘plot’?
A plot is a file that contains Hashes, these hashes are used to mine burst. A plot is tied to an account, but they can be created (with the same account ID) on other machines and connected back to your miner(s).
16( Where can I trade/buy/sell Burst?
A list of exchanges is maintained on https://www.reddit.com/burstcoin/ (on the right, ‘Exchanges’ tab) the biggest at the moment are Bittrex and Poloniex, some offer direct Fiat-to-Burst purchase (https://indacoin.com for example)
17( Do I have to store my Burst off the exchange?
No, but it’s safer from hackers who target exchanges, if you cannot guarantee the safety or security of your home computer from Trojans etc, then it might be best to leave on an exchange (but enable 2FA security on your account PLEASE!)
18( What security measures can I take to keep my coin safe?
When you create an account, sign out and back in to your wallet (to make sure you have copied the pass phrase correctly) and keep multiple copies of the key (at least one physically printed or written down and in a safe place, better in 2 places) do not disclose the passphrase to anyone. Finally use either a local wallet or a trusted web wallet (please research before using any web wallet)
19( How can I help Burst?
Run a wallet, which will act as a node (or if you’re a programmer, contact the Dev team Bring attention to burst (without ‘shilling’ or trying to get people to buy) And help translate into your local language
Be a productive member of the community and contribute experience and knowledge if you can, or help others get into Burst.
20( Will I get coins on the fork(s) and where will they be?
There will be no new coin, and no new coins to be given/air dropped etc, the forks are upgrades to burst and there will not be a ‘classic’ or ‘new’ burst.
21( Will I need to move my Burst off of the exchange for the fork?
No, your transactions are on the block chain, which will be used on the fork, they will be visible after the move; nothing will need to be done on your side.
22( Where can I read about the progress of Burst and news in general on the community?
There is no finer place than https://www.burstcoin.ist/
23( What are the communities for Burst and the central website?
Main website: https://www.burst-coin.org/
Reddit: https://www.reddit.com/burstcoin and https://www.reddit.com/burstcoinmining/
Burstforum.net: https://www.burstforum.net/
Getburst forum: https://forums.getburst.net/

Other ways to talk to the community:
Discord: https://discordapp.com/invite/RPhpjVv
Telegram (General): https://t.me/burstcoin
Telegram (Mining): https://t.me/BurstCoinMining
24( When will Burst partner up with a company?
Burst is a currency, the USD does not ‘partner up’ with a company, the DEV team will not partner up and give over to special interests.
25( Why is the DEV team anonymous?
They prefer anonymity, as it allows them to work without constant scrutiny and questions unless they wish to engage, plus the aim is for Burst to become a major contender, and this brings issues with security. They will work and produce results, they owe you nothing and if you cannot see the vision they provide then please do not ‘invest’ for short term gain.
26( When moon/Lambo/$100/make me rich?
My crystal ball is still broken, come back to the FAQ later for answer (seriously, this is a coin to hold, if you want to day-trade, good luck to you)
27( How can I better educate myself and learn about Dymaxion?
Read about the Dymaxion here: https://www.reddit.com/burstcoin/wiki/dymaxion
28( My reads are slow, why?
There are many reasons for this, if your computer has a decent spec it’s likely due to USB3 hub issues, or plugging into a USB2 hub, but other reasons can be multiple plots in the same folder, but it’s best to visit the mining subreddit. They can help more than an simple FAQ https://www.reddit.com/burstcoinmining/
29( I have a great idea for Burst (not proof of stake related)?
Awesome! Please discuss with the DEV team on discord https://discordapp.com/invite/RPhpjVv
(Please be aware that this is a public forum, you need to find who to ask/tell)
30( I have a great idea for Burst (Proof of stake related)?
No. if you want a POS, find a POS coin. On the tangle which is being implemented a POS/POW/POC coin can be created, but BURST will always be POC mined. You are welcome to implement a proof of stake coin on this!
31( Will the Dev team burn any coins?
Burst is not an ICO, so any coins will need to be bought to be burnt. You are welcome to donate, but the DEV team have no intention of burning any coins, or increasing the coin cap.
32( When will there be an IOS wallet?
IOS wallet is completed; we are waiting for it to go on the app store. Apple is the delaying factor.
33( Why do overlapping plots matter?
Plots are like collections of lottery tickets (and if only one ticket could win). Having 2 copies is not useful, and it means that you have less coverage of ‘all’ the possible numbers. It’s not good, avoid.
34( My local wallet used to run, I synchronised it before and now it says ‘stopped’. when I start it, it stops after a few seconds, what should I do?
I suggest that you change the database type to portable MariaDB (on Qbundle, at the top, ‘Database’ select, ‘change database’) and then re-import the database from scratch (see 35)
35( Synchronising the block chain is slow and I have the patience of a goldfish. What can I do?
On Qbundle , ‘Database’ select ‘Bootstrap chain’ and make sure the CryptoGuru repository is selected, then ‘start Import’ this will download and quickly stuff the local database (I suggest Portable MariaDB, see 34) (lol, loop)
36( What will the block reward be next month/will the block rewards run out in 6 months?
https://www.ecomine.earth/burstblockreward/ Rewards will carry on into 2026, but transaction fees will be a bigger % by then, and so profitable mining will continue.
37( How can I get started with Burst (wallet/mining/everything) and I need it in a video
https://www.youtube.com/watch?v=LJLhw37Lh_8 Watch and be enlightened.
38( Can I mine on multiple machines with the same account?
Yes, if you want to pool mine this can be done (but be prepared for small issues like reported size being incorrect. Just be sure to keep question 33 in mind.)
39( Why do some of my drives take forever to plot?
Most likely they are SMR drives, it’s best to plot onto another SSD and then move the finished plot/part of a plot across to the SMR drive as this is much quicker. SMR drives are fine on the read, just random writes that are terrible.
So plot an SMR drive quickly, plot to a non SMR or better still SSD drive, in as big a chunk as possible (fewer files better) and move. a version of Xplotter, called Splotter, can do this easily.
https://github.com/NoParamedic/SPlotter
40( I have a great idea; why not get listed on more exchanges!!
Exchanges list coins because of 2 reasons:
  1. Clients email and REQUESTING Burst and provide details like:
    i. https://www.burst-coin.org/information-for-exchanges
  2. The coin pays (often A LOT, seriously we’ve been asked for 50 BTC)
I suggest you speak with your exchange and ask ‘when will they offer Burst?’
41( Do you have a roadmap?
https://www.burst-coin.org/roadmap
42( Why is the price of Burst going up/down/sideways/looping through time?
The price of burst is still quite dependent upon Bitcoin, meaning that if Bitcoin gains, the value of Burst gains, if Bitcoin drops then Burst also drops. If there is news for Burst then we will see something independent of Bitcoin moving. Variations can be because of people buying in bulk or selling in bulk. There are also ‘pump and dump’ schemes that we detest, that can cause spikes in price that have nothing to do with news or Bitcoin, just sad people taking advantage of others.
43( Where is the best place to go with my mining questions?
https://www.reddit.com/burstcoinmining/
or https://t.me/BurstCoinMining
44( What hardware do you advise me to buy, is this computer good?
See question 43 for specific questions on hardware, it depends on so many variables. The ‘best’ in my opinion is a 36 bay Supermicro storage server, usually they have dual 6-core CPU’s and space for 36 drives. No USB cables, plotting and mining monster, anything else, DYOR.
45( Where do you buy your hard drives?
I have bought most from EBay in job lots, and some refurbished drives with short warranties. Everything else I have bought, from Amazon.
46( Can I mine on my Google drive/cloud based storage?
In short: no. If you want to try, and get to maybe 1 TB and then find that your local connection isn’t fast enough, or that shortly after, your account is blocked for various reasons. Please be my guest.
47( Can I mine on my NAS?
Some you can mine with the NAS (if it can run the miner, it can scan locally) but generally they’re not very fast. good for maybe 16 TB? Having a plot on a NAS and mining from another computer depends on the network speed between the NAS and scanning computer. I believe you can scan about 8 TB (maybe a bit more) and keep the scan times to within acceptable, but YMMV.
48( How can I set up a node?
No need to set up a node, just set up a wallet (version 2.0.4) or Qbundle (2.2) and it will do the rest
49( Are the passphrases secured?
I’ll leave the effort to a few people to show how secure a 12-word passphrase is: https://burstforum.net/topic/4766/the-canary-burst-early-warning-system Key point: brute forcing it will be around 13,537,856,339,904,134,474,012,675,034 years.
50( I logged into my account (maybe with a different burst ID) and see no balance!!
I have dealt with this very issue multiple times, and there are only 3 options:
  1. You have typed in the password incorrectly
  2. You have copy-pasted the password incorrectly
  3. You are trying to log into a ‘local wallet’ which the block chain has not finished updating
The last one generally leaves the burst ID the same, but old balances will show. No, this is not a security problem, and yes, windows loves to add spaces after the phrase you enter when copied, and that space is important in getting to your account.
51( Are there channels for my language?
Telegram:
Spanish: https://t.me/burstcoin_es
German: https://t.me/Burstcoinde
Italian: https://t.me/BurstCoinItalia
Forum:
Spanish: https://burst-coin.es/index.php/forum/index
Discord:

Bulgarian: https://discord.gg/r4uzTd
(there are others, please contact me to put up)
52( I am mining in a pool, and it says that my effective capacity is lower than I actually have, why?
  1. If you've not been mining for >48 hours, or just added additional capacity, it will take time.
  2. The value fluctuates (normally, +-5% but can be up to 10% at times)
  3. Read on the ‘Quick info’ tab about adjusting your deadline to compensate for changes i. revisit once a month for best results
  4. If you have overlapping plots it will also be lower so be aware of this (see question 33)
53( What pool should I join?
First of all, read question 9, after you have understood that it depends on the size (and how patient you are) select from the following list: https://www.ecomine.earth/burstpools/
54( What miner to use?
I use Blago’s miner, there are many out there but Blago’s works for me on CPU mining, it can be found in Qbundle.
55( What Wallet to use (I use windows)?
Qbundle: https://github.com/PoC-Consortium/Qbundle/releases/ guide: https://burstwiki.org/wiki/QBundle
56( What Wallet to use (Linux)?
https://package.cryptoguru.org/ for Debian and Ubuntu, for Mac. read:
https://www.ecomine.earth/macoswalletinstallguide/
57( Will i need to 'replot' after POC2 (second fork) happens?
No, there will be a tool which will optimise, but it is not CPU intensive (it basically re-shuffles your plot) and is just IO intensive. You do not need to replot.
TurboPlotter and https://github.com/PoC-Consortium/Utilities/tree/mastepoc1to2.pl are tools that will/can be used to actuate optimization, but PLEASE wait with optimization until after the hard fork.
58( Will the transaction fee always be 1 burst?
No, dynamic fees are coming in the next fork.

Why is does it take so long to shut down an node used only as a JSON-RPC server?

I'm trying to sync a full node that will only be used as a JSON-RPC server (no mining). I tried to modify the config file and added a service unit, so that the node can run in a low-end VPS with minimum RAM and CPU capabilities. The problem is that the server takes too long to stop, and it's terminated by the system, so it always start rewinding blocks that have been already downloaded.
Here is my configuration file:
server=1 daemon=1 #debug=mempool debug=rpc # If run on the test network instead of the real bitcoin network # testnet=1 # You must set rpcuser and rpcpassword to secure the JSON-RPC api # Please make rpcpassword to something secure, `5gKAgrJv8CQr2CGUhjVbBFLSj29HnE6YGXvfykHJzS3k` for example. # Listen for JSON-RPC connections on  (default: 8332 or testnet: 18332) rpcuser=myuser rpcpassword=pypassword rpcport=8332 # Enable blocks pruning #prune=550 # Limit dbcache=50 maxconnections=4 rpcthreads=2 
And the service unit:
# It is not recommended to modify this file in-place, because it will # be overwritten during package upgrades. If you want to add further # options or overwrite existing ones then use # $ systemctl edit bitcoind.service # See "man systemd.service" for details. # Note that almost all daemon options could be specified in # /etc/bitcoin/bitcoin.conf [Unit] Description=Bitcoin daemon After=network.target [Service] ExecStart=/usbin/bitcoind -daemon=0 -datadir=/home/jsonrpc/bitcoin -conf=/home/jsonrpc/bitcoin/settings.conf ExecStop=/usbin/bitcoin-cli -datadir=/home/jsonrpc/bitcoin -conf=/home/jsonrpc/bitcoin/settings.conf stop # Creates /run/bitcoind owned by bitcoin #RuntimeDirectory=/home/jsonrpc/bitcoin WorkingDirectory=/home/jsonrpc/bitcoin User=jsonrpc Group=jsonrpc TimeoutStopSec=15m #CPUQuota=4% #MemoryLimit=128M #IOReadIOPSMax=10 #IOWriteIOPSMax=10 Type=simple #Restart=on-failure # Hardening measures #################### # Provide a private /tmp and /vatmp.

Dogecoin on Linux - The Complete Beginner's Guide

I'm writing this because I couldn't find a single condensed guide on compiling the wallet and running mining software on linux, specficially Ubuntu/Linux Mint. I combed Bitcoin and Litecoin forums for similar problems I was running into and eventually got everything nailed down, so here it is in one place, for new Shibes.
If you want to make a Dogecoin directory in your downloads folder to keep things organized, you will need to modify these commands to refelct the change. So instead of going to ~/Downloads/ you will need to go to ~/Downloads/Dogecoin and be sure to put the zipped files there when you download them, but the commands will be the same otherwise.
cwayne18 put in the work to make a PPA for the QT client here.
Ubunutu/Mint/Debian users should be able to install the client with the following commands:
sudo add-apt-repository ppa:cwayne18/doge sudo apt-get update && sudo apt-get install dogecoin-qt 
To update using this method, run
sudo apt-get update && sudo apt-get upgrade dogecoin-qt 
Compiling the Wallet Manually
I suggest using the PPA above, but if you want to compile manually, here you go.
1)Download the newest source from here. If you want to check out the Github page, click here
2)Unzip the package with the native client OR, navigate to your downloads and unzip
cd ~/Downloads unzip dogecoin-master.zip 
3)Now it's time to compile. You will need to install the dependencies, just copy and paste the following code. It will be a fairly large download and could take some time. It is always important to update before installing any new software, so we'll do that first and then install the dependencies.
sudo apt-get update sudo apt-get upgrade sudo apt-get install libssl-dev libdb-dev libdb++-dev libqrencode-dev qt4-qmake libqtgui4 libqt4-dev sudo apt-get install libminiupnpc-dev libminiupnpc8 libboost-all-dev build-essential git libboost1.53-all-dev 
4)Once that is done, go to the doge-coin master directory and compile:
cd ~/Downloads/dogecoin-maste sed -i 's/-mgw46-mt-sd-1_53//g' dogecoin-qt.pro qmake USE_UPNP=- USE_QRCODE=0 USE_IPV6=0 make -j3 
After running the qmake command you will likely see some text similar to
Project MESSAGE: Building without UPNP support Project MESSAGE: Building with UPNP supportRemoved plural forms as the target language has less forms. If this sounds wrong, possibly the target language is not set or recognized. 
It's perfectly normal, so don't worry about that.
Your Dogewallet is ready to go! The executable is in ~/Downloads/dogecoin-maste and called dogecoin-qt. Your wallet information is in ~/.dogecoin. You can run the wallet at any time by opening terminal and typing
cd ~/Downloads/dogecoin-maste ./dogecoin-qt 
Future upgrades to dogewallet are easy. Back up your wallet.dat, and simply follow the same directions above, but you'll be unzipping and building the newer version. You will likely need to rename the old dogecoin-master directory in ~/Downloads before unzipping the newest version and building. Also, it is likely that you will not need to install the dependencies again.
Alternate Method For Installing Dogecoin Wallet from Nicebreakfast
After installing the dependencies listed in step 3, open terminal, then navigate to where you want Dogecoin Wallet stored and run:
git clone https://github.com/dogecoin/dogecoin ./autogen.sh ./configure make 
then when the wallet is updated just run
git pull 
from the dogecoin directory.
GPU Mining
GPU mining requires CGminer. My suggestion is to get the executable already built. The creator of cgminer has removed the built file from his website, but I've uploaded it here
sudo apt-get install pkg-config opencl-dev libcurl4-openssl-dev autoconf libtool automake m4 ncurses-dev cd ~/Downloads tar -xvf cgminer-3.7.2-x86_64-built.tar.bz2 
Don't use anything newer than 3.7.2. The newer versions of CGMiner don't support GPU mining.
That's it! You have cgminer ready to go! You will run cgminer with the following syntax
cd ~/Downloads/cgminer-3.7.2-x86_64-built/ ./cgminer --scrypt -o stratum+tcp://SERVERNAME:PORT -u WORKER.ID -p PASS 
A good guide for fine tuning cgminer can be found here; follow the litecoin example.
EDIT
I had trouble getting cgminer running with a single line command, but running it via an executable .sh file works. This is covered in the cgminer setup guide I posted above but I'll put it here too. In the same directory that has the cgminer executable, you need to make a file called cgminer.sh and make it executable. It should contain the follwing:
export GPU_USE_SYNC_OBJECTS=1 export GPU_MAX_ALLOC_PERCENT=100 export DISPLAY=:0 find *.bin -delete sleep 5 ./cgminer 
Then you can call cgminer in terminal by doing ./cgminer.sh You will need a cgminer.conf file containing all your options. All of this is covered in the guide that is linked above.
A quick note about AMD drivers: They used to be a huge PITA to install and get working, but the newest Catalyst drivers are great. There's a GUI installer, everything works out of the box, and there is a lot of documentation. You can download them here: AMD Catalyst 14.6 Beta Linux
CPU Mining
For CPU mining I use minerd because it doesn't require any work to get running, simply download it and get to work. Download the built file for your machine 32-bit or 64-bit, and then unzip it and you're ready to go!
cd ~/Downloads tar -xvf pooler-cpuminer-2.3.2-linux-x86.tar.gz 
The executable is called minerd and it will be in ~/Downloads but you can move it to wherever you like. To run it, pull up terminal and do
cd ~/Downloads minerd --url=stratum+tcp://SERVER:PORT --userpass=USERNAME.WORKERNAME:WORKERPASSWORD 
You're done! Happy mining!
Common Issues
I ran into this and I've seen others with this problem as well. Everything installs fine but there is a shared library file that isn't where it should be. In fact, it isn't there at all.
 libudev.so.1: cannot open shared object file: No such file or directory 
In terminal, do
sudo updatedb locate libudev.so.0.13.0 
And it will probably return a path /lib/x86_64-linux-gnu. Inside that directory there's a library file called libudev.so.0.13.0. You'll need to make a symlink (aka shortcut) that links libudev.so.1 to libudev.so.0.13.0 So, assuming you're working with libudev.so.0.13.0 do this
cd /lib/x86_64-linux-gnu sudo ln -s libudev.so.0.13.0 libudev.so.1 
Now if you do
ln -l 
You should see
libudev.so.1 -> ./libudev.so.0.13.0 
Meaning you've made the symlink. Also, the text for libudev.so.1 will be blue.

Lore v2 QT on Raspberry Pi

Hello,
 
To follow up to mindphuk's excellent piece on building the headless client on Raspberry Pi (https://www.reddit.com/blackcoin/comments/6gkjrw/wip_blackpi_a_stake_device_based_on_raspberry/), I thought if anyone was interested I'd show you how to get the full QT version running on the Pi on the Jessie with Pixel desktop. This works and has been soak tested for several days now on a standard Raspberry Pi 3. I have since added some coins and it stakes a handful of times a day.
 
Running staking Lore clients paves the way for some of the future use cases of BLK utilising the Bitcoin 0.12 (and newer) core tech, including colored coins. So I'm going to leave this one going indefinitely to kickstart the number of Lore clients staking. It's certainly not mandatory but it will be good in the longer term to have a nice distribution of Lore staking clients.
 
The cross-compile which lets you create binaries for multiple platforms didn't work for the QT version on the Pi, so there is more to do than just running the binary unfortunately, as below. There are folks working on some much cleaner solutions than this for the Pi, with a custom front end, and where you won't have to do any mucking about. That is coming soon. In the meantime, if you enjoy a fiddle with such things, here's how to get this QT client working on your Pi.
 
These instructions assume you are starting from scratch with a completely blank OS.
 
Download Jessie with Pixel from: http://downloads.raspberrypi.org/raspbian/images/raspbian-2017-07-05/2017-07-05-raspbian-jessie.zip
 
Note they have since (August 2017) released a version called 'Stretch' which does not work with this guide. I'll see if I can come up with something new for that at some point and link to it here when I have. In the meantime the guide should work with the Jessie image above.
 
Unzip the file and extract the .img file to burn it onto Fresh SD card to boot from (to be safe, use 16GB or larger), using a tool like win32diskimager or Etcher.
 
Assuming you have keyboard/mouse and monitor plugged into your pi, boot it up and the Jessie Desktop will show.
 
Before we do anything else, you should increase the default swap size on the pi, as compiling certain libraries can exhaust the RAM and get stuck otherwise. To do this, launch a Terminal window and type:
 
sudo nano /etc/dphys-swapfile 
 
and Change the CONF_SWAPSIZE from 100 to:
 
CONF_SWAPSIZE=1024 
 
Exit nano with control + x to write out the file.
 
Then, run the following to restart the swapfile manager:
 
sudo /etc/init.d/dphys-swapfile stop sudo /etc/init.d/dphys-swapfile start 
 
Now, launch the browser and download the Lore 2.12 binaries for ARM here: https://mega.nz/#!k2InxZhb!iaLhUPreA7LZqZ-Az-0StRBUshSJ82XjldPsvhGBBH4 (Version with fee fix from 6 September 2017)
 
(If you prefer to compile it yourself instead, it is possible by following the instructions in the original article by Mindphuk just taking into account this is the newer version of the Lore client than when that was written (https://github.com/janko33bd/bitcoin/releases) and the versions of Boost and the Berkeley DB need to be the same as below.)
 
Double click the zip and extract the Lore binary files. Yes, at the moment they are all called 'bitcoin', not 'blackcoin' or 'Lore' - this is because the code derives from a recent bitcoin core implementation so this has not yet been updated. You can place these wherever you like.
 
In the Terminal window, change directory to where you put the binaries, e.g.:
 
cd Downloads/lore-raspberrypi-armv7-jessie-pixel chmod +x * 
 
That marks the binaries as executable.
 
Now, we need the Boost libraries installed for any of the Lore binaries to work. The project was done with Boost 1.62.0. Unfortunately the Jessie repository only goes up to 1.55, so we need to download and build 1.62 manually on the device.
wget https://sourceforge.net/projects/boost/files/boost/1.62.0/boost_1_62_0.tar.gz/download tar -xvzf download cd boost_1_62_0 sudo ./bootstrap.sh sudo ./b2 install 
 
(This will take almost 2 hours. Have a nice cup of tea and a sit down.)
 
When I came to run the binaries, I found they couldn't find Boost. Running this command fixes that:
sudo ldconfig 
 
Now we are going to install the packages which aren't already included in the default OS installation which the binaries need in order to run:
sudo apt-get install qrencode libprotobuf-dev libevent-pthreads-2.0-5 
 
Now we need to install the Berkeley Database version 6.2.23. This is the version Lore v2 uses. Bitcoin still uses 4.8 which is 10 years old! This doesn't take too long.
wget http://download.oracle.com/berkeley-db/db-6.2.23.tar.gz tar -xvzf db-6.2.23.tar.gz cd db-6.2.23/build_unix ../dist/configure --prefix=/usr --enable-compat185 --enable-dbm --disable-static --enable-cxx 
 
I find this next section of the Berkeley instructions worked better just switching to root, which can be fudged by running sudo su before the rest:
sudo su make make docdir=/usshare/doc/db-6.2.23 install chown -v -R root:root /usbin/db_* /usinclude/db{,_185,_cxx}.h /uslib/libdb*.{so,la} /usshare/doc/db-6.2.23 
 
Now we're going to go up a couple of directories to where the binaries were:
cd ../.. 
 
Then run the client!
./bitcoin-qt 
 
And there you have it. Should hopefully end up looking a bit like this: http://imgur.com/a/eEHGa
 
Using the Bootstrap can save a while syncing. Download it at: https://www.reddit.com/blackcoin/comments/6b3imq/blackcoin_bootstrapdat_up_to_block_1631800
 
Place the bootstrap.dat file into the ~/.lore directory.
 
Run ./bitcoin-qt again, it will say 'Importing Blocks' rather than 'Synchronising with Network'. My pi sync'ed fully in about 5-6 hours.
 
If you want peace of mind that Lore will always start on bootup into the Jessie w/Pixel desktop (i.e. after a power cycle), then you need to create a .desktop file in the following place.
sudo nano ~/.config/autostart/Lore.desktop 
 
And in it, enter the following (tailoring the Exec line below to the whereabouts of your bitcoin-qt file):
[Desktop Entry] Name=Blackcoin Lore Comment=Mining without the waste Exec=/home/pi/Downloads/lore-raspberrypi-armv7-jessie-pixel/bitcoin-qt Type=Application Encoding=UTF-8 Terminal=false Categories=None; 
 
Power usage and payback time
 
After a good while leaving it going by itself, the CPU load averages got down to almost zero, all of the time. Idling, the Pi uses a bit less than 3 watts. This means it would take two weeks to use one 1Kw/h of electricity.
 
If you pay e.g. 12.5 cents a unit, that's what you'd expect this to cost to run in a fortnight. That's around $0.25 a month or $3 a year. Green and cheap and helping to secure the BLK network. I paid for the year's worth of electricity in 2 days staking with 25k BLK. Makes mining look silly, huh? ;)
 
Securing your Pi
 
With staking, your wallet needs to be unlocked and as such, the keys to your wallet are on the device. In a clean and newly installed environment as described above, and if you don't allow others to use your device and there is no other software or nasties running on it, there is no real cause for concern. However, there are some basic security precautions you can take.
 
Firstly, if you have enabled SSH and are playing with your pi across your LAN (or worse, the Internet), you should immediately change the password for the default 'pi' user (which is preconfigured to be 'raspberry'). Simply log in as normal, then type:
 
passwd 
 
You'll be prompted to enter the old and the new passwords.
 
Security by default
 
Your Pi is likely, by default, to not be exposed to incoming connections from the outside world because your router is likely generating a private address range for your LAN (192.168.x.x or 10.0.x.x or 172.x.x.x) which means all incoming connections are effectively blocked at the router anyway unless you set up a 'port forward' record to allow packets arriving on certain ports to be forwarded to a specific internal IP address.
 
As for accessing your Pi across the internet, if you have set up a port forward, this likely has security ramifications. Even basic old fashioned protocols have proven in recent times to have uncaught flaws, so it's always advisable to lock down your device as much as possible, and even if you only plan to access the Pi over your LAN, install a firewall to configure this. I used one called ufw, because it's literally an uncomplicated firewall.
 
sudo apt-get install ufw sudo ufw allow from 192.168.0.0/16 to any port 22 sudo ufw --force enable 
 
This allows just port 22 (SSH) to be open on the Pi to any device on my LAN's subnet (192.168.0.x). You can change the above to a single IP address if paranoid, or add several lines, if you want to lock it down to your LAN and a specific external static IP address (e.g. a VPN service you use). To find out what subnet your router uses, just type:
 
ifconfig 
 
and you'll see on the interface you are using (either hard wired or wifi) the 192.168 or 10. or 172. prefix. Change the above rule so it matches the first two octets correctly (e.g. 10.0.0.0/16 if you're on a 10.0. address).
 
You may already use VNC to access your Pi's desktop across your LAN, this uses port 5900. Add a line like above to lock it down to an internal address. It's not a good idea to expose this port to the wider world because those connections are not encrypted and potentially could be subjected to a MITM attack.
 
You can query the status of the firewall like this:
ufw status 
 
And of course, try connecting remotely once you change the rules to see what works. You should consult the official documentation for further options: https://help.ubuntu.com/community/UFW
 
Back up & Recovery
 
There are again many ways to tackle this so I'll just speak about my basic precautions in this regard. Don't take it as a be-all-and-end-all!
 
The wallet.dat file is the key file (literally) containing all the private/public keys and transactions. This can be found in:
 
~/.lore 
 
You can navigate there using Jessie w/Pixel's own file manager or in a terminal window (cd ~/.lore). You can copy this file or, if you'd rather keep a plain text file of all your public and private keys, use the 'dumpwallet' command in the console. In Lore, go to Help > Debug Window > Console and type 'dumpwallet myfilename' where myfilename is the file you want it to spit out with all your keys in it. This file will end up in the same place you launch bitcoin-qt from.
 
The instructions earlier on, when running Lore for the first time intentionally left out encrypting your wallet.dat file because in order for the wallet to stake upon startup, it needs to have a decrypted key already. This isn't perfect, but after a power cycle, it would never stake unless you left it decrypted. So the best practice here is as soon as the wallet.dat file has left your device, i.e. you copy it to a USB stick for example, put it in an encrypted folder or drive (or both).
 
In Windows, one way is to use Bitlocker drive encryption for the entire drive. You should follow the instructions here to encrypt your flash drive before your wallet.dat is on there, and don't forget the password!!
http://infosec.nmsu.edu/instructions-guides/how-to-enable-bitlocker-to-go-for-external-hard-drives-and-usb-flash-drives/
 
On the Mac, I use a software package called Concealer to encrypt files I store on the Mac itself: http://www.belightsoft.com/products/conceale   There are almost certainly free packages with similar functionality, I have just used that one for years.
 
Either way, if you want to just make sure your USB drive is encrypted, you can do so in one-click in Finder before you put the sensitive files on it: http://lifehacker.com/encrypt-a-usb-stick-in-finder-with-a-click-1594798016
 
Note that these disk encryption methods may mean having to access the USB stick on a PC or Mac in order to retrieve the files in the event of a disaster. Be aware this may mean exposing them to more security issues if your computer is in any way compromised or someone nefarious has access to your computer. There are more 'manual' ways of backing up and recovering, such as literally writing down private/public key pairs which this guide doesn't go into, but may suit you better if paranoid about your setup.
 
Recovery
 
The wallet.dat file has everything in it you need to recover your wallet, or if you used 'dumpwallet', the file you saved out has all the keys.
 
Wallet.dat method: Install Lore as normal then replace any auto-generated wallet.dat in ~/.lore directory with your backup. If a lot of time has elapsed and many transactions have occurred since your backup, launch lore with:
./bitcoin-qt -rescan 
 
And if that doesn't do the job, do a full reindex of the blockchain:
 
./bitcoin-qt -reindex 
 
If you used the dumpwallet command, install Lore then place the file containing all the keys that you saved out in the same directory as bitcoin-qt. In Lore, go to Help > Debug Window > Console and type 'importwallet myfilename' where myfilename is that file containing all the keys. The wallet should automatically rescan for transactions at that point and you should be good to go.
 
There are a million ways to do effective security and disaster recovery, but I hope this shows you a couple of basic precautionary ways. There are discussions about better ways to stake without compromising too much security which are happening all the time and developments in this regard will happen in time.
 
In the meantime, feel free to comment with your best practices.

Planning on selling my current PC to go towards a a new $1500 build

Build Help/Ready:

Hello, I am planning on selling my current PC I built a few years ago to go towards this new one. It's listed below, any input as to a fair price I could sell for would be great
Have you read the sidebar and rules? (Please do)
Yes
What is your intended use for this build? The more details the better.
Gaming and Programming. The ability to dual boot Linux and run VMs in Windows would be a huge plus. For whatever reason my motherboard will just not boot into Ubuntu or even run a usable VM
I have gotten into mining bitcoin recently (Using NiceHash), however it's more of just a hobby to save up for a steam game eventually or something. I don't expect any real profit
If gaming, what kind of performance are you looking for? (Screen resolution, framerate, game settings)
I have a 4K monitor, but I would like to be able to play games at high/ultra possibly at 1440p
What is your budget (ballpark is okay)?
About $1500
In what country are you purchasing your parts?
Canada
Post a draft of your potential build here (specific parts please). Consider formatting your parts list. Don't ask to be spoonfed a build (read the rules!).
My Planned Build: (Already have a 480GB SSD)

Provide any additional details you wish below.
I'll probably end up swapping out the CPU cooler for liquid eventually, as well as installing more RAM
EDIT: With that liquid cooler I definitely plan on overclocking
Thanks for the help!

Use the BTCP full Node on a Ubuntu 16.04 LTS from Terminal

In this post I want to show some use of the CLI BTCP wallet from linux terminal.
DISCLAIMER:
First of all, use this tutorial with small amount of BTCP, for example i used 0,01 BTCP, until you feel confortable with commands. An error can happen easily and as result you can loose your money. Be careful! Do it at your risk!
I consider you have already installed the wallet following this instructions:
https://github.com/BTCPrivate/bitcoinprivate
I use Ubuntu 16.04 LTS 64bit, but commands are similar for the windows client.
Open a terminal from your Ubuntu Desktop:
[email protected]:~$ 
type:
[email protected]:~$ ./BitcoinPrivate/src/btcpd --daemon 
you should see the message:
BTCP server starting 
This means the wallet is running in daemon mode.
to stop the node just typing:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli stop 
Answer:
BTCP server stopping 
You can also run the wallet in terminal, is nice to see it, let's try:
 [email protected]:~$ ./BitcoinPrivate/src/btcpd 
You will see the BTCP logo in text mode and the following info:
Thank you for running a Bitcoin Private node! You're strengthening the network and contributing to a social good. To ensure you are fully protecting your privacy when running BTCP, see . Block height | 340079 Connections | 8 Network solution rate | 8359387 Sol/s You are currently not mining. To enable mining, add 'gen=1' to your btcprivate.conf and restart. Since starting this node 1 minutes, 33 seconds ago: - You have validated 695 transactions! [Press Ctrl+C to exit] [Set 'showmetrics=0' to hide] 
See, you can also mine using the wallet! Nice! Just add gen=1 in the file btcprivate.conf. Probably you will never mine a coin, but still you to strenght the net, so, you can try if you want, then disable it when done:
Press CTRL and C to stop the server, then restart the server in daemon mode otherwhise you have to open a new terminal.
Let's find btcprivate.conf and other useful files:
[email protected]:~$ cd .btcprivate [email protected]:~/.btcprivate$ ls 
Answer:
blocks btcprivate.conf chainstate db.log debug.log fee_estimates.dat peers.dat wallet.dat 
You see here: btcprivate.conf and wallet.dat
Edit configuration file:
[email protected]:~/.btcprivate$ pico btcprivate.conf 
add gen=1 if you want to mine, then CTRL X and Y to save.
Restart the wallet....and....
Block height | 340091 Connections | 8 Network solution rate | 8211926 Sol/s Local solution rate | 0.0075 Sol/s Since starting this node 8 minutes, 5 seconds ago: - You have validated 684 transactions! - You have completed 1 Equihash solver runs. You are mining with the default solver on 1 threads. 
Congratulations! You are mining!
Now have a look to the wallet.dat file:
Nb: wallet.dat is your wallet!! If you delete it you will loose all your money!!!
wallet.dat is not encrypted, so, if you want to backup it i do as follows:
[email protected]:~/.btcprivate$ cp wallet.dat home/btcp/Desktop/wallet_btcp_back.dat 
Now you will find the wallet on your desktop. Zip it with an AES256 encryption and a strong password. Test if it works properly: extract it again and copy it in the directory, but before make an other copy of the wallet.dat file. Beware! I almost deleted the file once!
Nb: wallet.dat is your wallet!! If you delete it you will loose all your money!!!
Go back to your home directory, now, we want to play with our wallet:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli help 
if everything is running properly, you will see a list of commands like this:
z_exportwallet "filename" z_getbalance "address" ( minconf ) z_getnewaddress z_getoperationresult (["operationid", ... ]) z_getoperationstatus (["operationid", ... ]) z_gettotalbalance ( minconf ) z_importkey "zkey" ( rescan startHeight ) z_importwallet "filename" z_listaddresses z_listoperationids z_listreceivedbyaddress "address" ( minconf ) z_sendmany "fromaddress" [{"address":... ,"amount":...},...] ( minconf ) ( fee ) z_shieldcoinbase "fromaddress" "tozaddress" ( fee ) zcbenchmark benchmarktype samplecount zcrawjoinsplit rawtx inputs outputs vpub_old vpub_new zcrawkeygen zcrawreceive zcsecretkey encryptednote zcsamplejoinsplit [email protected]:~$ 
Nice! Wallet is running properly. Now try an other command: getinfo
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getinfo 
Answer:
{ "version": 1001251, "protocolversion": 180004, "walletversion": 60000, "balance": 0.00000000, "blocks": 340074, "timeoffset": 0, "connections": 8, "proxy": "", "difficulty": 167290.7158221716, "testnet": false, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000, "relayfee": 0.00000100, "errors": "" } [email protected]:~$ 
You see some useful info about your wallet/node:
blocks is the block heights, in this case is synced with the network. If not the number would be lower.
The wallet is connected to other 8 nodes, the balance is 0.00 BTCP
An other info command can be getblockchaininfo:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getblockchaininfo 
Answer:
{ "chain": "main", "blocks": 340074, "headers": 340074, "bestblockhash": "0000000145c0011d8e914f4ba68d1443c7ae0dd15bdf0bc300994dd5282710aa", "difficulty": 165971.1181999981, "verificationprogress": 0.9999992572690658, "chainwork": "0000000000000000000000000000000000000000000000000002e8314e4484da", "pruned": false, "commitments": 663480, 
we see syncing is almost finished:
"verificationprogress": 0.9999992572690658, (99,99999%)
Now test the wallet with command getwalletinfo
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00000000, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 0, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } [email protected]:~$ 
Now we want to send some btcp to this wallet. First we need an address, get one using getnewaddress:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getnewaddress 
Answer:
b1Cabjwvcce7N8ea9Gxxxxxxxxxxxxxxxx [email protected]:~$ 
Send at this address some BTCP, i sent 0.01 for testing purpose using your ledger, or your wallet, then check if the transaction is done:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00000000, "unconfirmed_balance": 0.01000000, "immature_balance": 0.00000000, "txcount": 1, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } 
Done! Unconfirmed balance is 0.01! Just wait some confirmations.
after a while:
"walletversion": 60000, "balance": 0.01000000, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 1, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 
Now send the coins to a new address. I am using this command:
sendtoaddress "btcpaddress" amount ( "comment" "comment-to" subtractfeefromamount )
subtractfeefromamount parameter can be true or false
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli sendtoaddress "b1Nb42GoK9kmsxxxxxxxxxxxxx" 0.01 "" "" true 
Answer:
2c5d3d1a3b5eec414b721d3817487f53c5eebxxxxxxxxxxxxxxx [email protected]:~$ 
Now check the wallet:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli getwalletinfo 
Answer:
{ "walletversion": 60000, "balance": 0.00999808, "unconfirmed_balance": 0.00000000, "immature_balance": 0.00000000, "txcount": 2, "keypoololdest": 1528833903, "keypoolsize": 101, "paytxfee": 0.00000000 } 
I sent BTCP to the same wallet, so now i have less BTCP because of the fees.
try more commands:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listreceivedbyaddress 
Answer:
[ { "address": "b1Ep2wi2tUnKf433Vaxxxxxxxxxxxx", "account": "", "amount": 0.01000000, "confirmations": 6, "txids": [ "833533440a13c09fda6e90d0c5xxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ] }, { "address": "b1Nb42GoK9kmsVZ9KPxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "account": "", "amount": 0.00999808, "confirmations": 1, "txids": [ "2c5d3d1a3b5eec414b721d3817487f53c5xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" ] } 
This is the list of all used addresses.
Now find the money and the address where they are: use listunspent
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listunspent 
Answer:
[ { "txid": "2c5d3d1a3b5eec414b721d381748xxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "vout": 0, "generated": false, "address": "b1Nb42GoK9kxxxxxxxxxxxxxx", "account": "", "scriptPubKey": "76a914c6bdf3bc8aedxxxxxxxxxxxxxxxxxx", "amount": 0.00999808, "confirmations": 6, "spendable": true 
Well done.
Other useful commands can be: dumpprivkey to extract the private key from an address
Be careful! Exposing your private keys will end in loosing your money
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli dumpprivkey b1Ep2wi2tUnxxxxxxxxxxx 
Obtaining the pvt key:
Kz29e62Bmxxxxxxxxxxxxxxxxxxxxxxx 
And now, swipe the private key using the command: importprivkey "btcpprivkey" ( "label" rescan )
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli importprivkey "Kz29e62Bmxxxxxxxxxxxxxxxxxxxxx" "" true 
Let's do a shielded transaction!
first, you must have a z_address:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_getnewaddress 
Answer:
zkEvCiVwgHb3NFi2ee9HGPjno2xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx 
Check balaces, with also z_addres:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_gettotalbalance 
Answer:
{ "transparent": "0.00999808", "private": "0.00", "total": "0.00999808" } 
Now send some BTCP to the z_address. First, check where BTCP are:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli listunspent 
Output:
[ { "txid": "72f568d1ed51524b69f1xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx", "vout": 0, "generated": false, "address": "b1LDhxBJxxxxxxxxxxxxxxxxxxxxxx", "scriptPubKey": "76axxxxxxxxxxxxxxxxxxxxxxxxxxxxxxe088xx", "amount": 0.00889808, "confirmations": 556, "spendable": true } ] 
Now, sent a little transparent amount to the shielded address we got before:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_sendmany "b1LDhxBJxxxxxxxxxxxxxxxxxxxxxx" "[{\"amount\":0.001, \"address\":\"zkEvCiVwgHb3xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx\"}]" 
Output:
opid-xxxxxxx-36c4-xxxx-beb2-xxxxxxxxxxxx 
Now your PC will work a while, it's CPU consuming...so...check:
[email protected]:~$ ./BitcoinPrivate/src/btcp-cli z_getoperationresult 
until you receive the answer:
[ { "id": "opid-xxxxxx-xxxxx-4a5d-beb2-xxxxxxxxxx", "status": "success", "creation_time": 1529426885, "result": { "txid": "f87e8d5e96a8a0xxxxxxxxxxxxxxx" }, "execution_secs": 216.686332567, "method": "z_sendmany", "params": { "fromaddress": "b1LDhxxxxxxxxxxx", "amounts": [ { "amount": 0.001, "address": "zkEvCiVwgHb3NFxxxxxxxxxxxxxxxxxxR" } ], "minconf": 1, "fee": 0.0001 } } ] 
Done! On my old PC it took 216.68 seconds!
Next will be a reverse operation, from Shielded address to transparent address. See you soon....
Play with your full node wallet and have fun.
Remember: these commands are almost the same in all the bitcoin based coins, so you also learnt how to use many other wallets!

How To Mine Doge with Ubuntu 13.10. (Part 1, for AMD Graphics Cards)

I feel the community really needs a resource like this. Because if I had a Doge for every-time taught a newbie how to Mine on Ubuntu, I would be a very rich doge!
EDIT: Sorry if it looks funny, Reddit doesn't like the numbers I put in for some reason.
If you have Ubuntu you have likely not upgraded because you think you cant mine on 13.10, and while that has been true in the past, a few people have got it figured out. So feel free to upgrade. If you are not on Ubuntu, Seriously you should consider using it. Even if its just on an older desktop.
Alright, so lets get a few things clear, I am assuming that you just FRESHLY installed Ubuntu 13.10 x64 on your system. I am assuming that you have no drivers, and no miners. You will need at least a key board and a mouse. The guide will be done in several parts, this first part is for most AMD Graphics cards. If you have an Nvidia, or just want to mine with your CPU, please check back later for those guides!
When reading this guide, please remember that as I give you commands to type into the terminal, Anything between { and} must be included. Do not copy and paste the {}.
Lets get started, If you have not already done so, Install Ubuntu 13.10 64Bit From Here (http://www.ubuntu.com/index_asus.html)
*1. Lets start by making sure you are up to date. Open up the terminal and enter this:
{sudo apt-get update && sudo apt-get upgrade} 
Let that run for a bit.
*2. Once that has finished we are going to download some applications we will need:
{sudo apt-get install dh-make dh-modaliases execstack libxrandr2 libice6 libsm6 libfontconfig1 libxi6 libxcursor1 libgl1-mesa-glx libxinerama1 libqtgui4} 
*3. Once that has run its course we are going to install the ssh server. Remember this command is going to make your computer shut down. While it is shut down, carefully install your graphics cards. If you don't have any experience with this, I suggest you 3 minutes to watch this guide, because failure to install a graphics card the right way can destroy it.
(http://www.youtube.com/watch?v=O9x097QRXeA)
{sudo apt-get install openssh-server sudo shutdown now} 
*4.Install your Card(s) and turn the computer back on.
*5. Make a new folder called "AMD DRIVERS123" inside of your download folder. Downoad the following 3 things into that folder. (1. AMD Drivers: http://support.amd.com/en-us/download/incomplete) (2. AMD APP SDK: http://developer.amd.com/tools-and-sdks/heterogeneous-computing/amd-accelerated-parallel-processing-app-sdk/downloads/) (3. AMD ADL SDK:http://developer.amd.com/tools-and-sdks/graphics-development/display-library-adl-sdk/)
*6. Ok, now we need to unzip and compile those drivers. So, open a terminal my right clicking inside of "AMD DRIVERS123". The enter this:
{unzip amd-catalyst*.zip chmod +x amd-catalyst*.run} {sudo ./amd-catalyst*.run --buildpkg Ubuntu/saucy} 
*7. Now we need to install the drivers. Enter the code exactly as you see it, don't worry, the first command will fail, we are expecting it too.
{sudo dpkg -i fglrx*.deb} {sudo apt-get -f install} {sudo dpkg -i fglrx*.deb} {sudo reboot} 
Your computer should now reboot.
(If this failed, you probibly need to remove the old drivers. Do this
{cd /etc/default sudo pico grub} 
Change the line:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset" 
Now save by pressing [CTRL+x]
{sudo update-grub} this will make the change perminent. {sudo reboot -n} Reboot with new settings. Once it starts back up try installing the new drivers again.) 
*8.GREAT! You are really on a roll! Now we need to update AtiConfig
{sudo aticonfig --initial --adapter=all} 
*9.Time to install the APP ADK:
{tar xvf AMD-APP-SDK*.tgz} {sudo ./Install-AMD-APP.sh} {sudo reboot} 
*10. WOOT! You are so close to diggin that sweet Doge!! Its time to download CGMiner. IMPORTANT NOTE! You need to get CGminer 3.7, IT IS THE ONLY ONE THAT WILL WORK. Do not get any older or newer, Just this. :
{sudo apt-get install git unzip git clone -b 3.7 https://github.com/ckolivas/cgminer} 
*11. Ok, now go back to "AMD DRIVERS123", Unzip AMD SDL SDK 6.0. Once you have it unzipped, go the file called "include", open it up, copy everything inside, then go find CGminer. Copy these files into the CGminer file called ADL_SDK.
*12. To install CGminer, we are going to need a few things. Get all of these.
{sudo apt-get install build-essential autoconf libtool libcurl4-openssl-dev libncurses5-dev pkg-config libudev-dev} 
*13. Lets go ahead and compile CGminer.
{cd cgminer} {./autogen.sh} 
*14. Ok, when you did that, it told you GPU was not supported, time to fix it.
{./configure --enable-opencl --enable-scrypt} 
(if you did it right you should now get this: OpenCL...............: FOUND. GPU mining support enabled scrypt...............: Enabled ADL..................: SDK found, GPU monitoring support enabled)
*15. If everything has been good so far then
{make} 
*16. MATHEMATICAL! Now lets get it set up to run a test.
{nano test.sh} {!/bin/bash export DISPLAY=:0 export GPU_MAX_ALLOC_PERCENT=100 export GPU_USE_SYNC_OBJECTS=1} {./cgminer -n} 
*17. Now save by hitting [Control+x][y][Enter]
*18.Lastly lets CHmod test.sh
{chmod+x test.sh} 
*19. TIME TO RUN THE TEXT!!!
{./test.sh} 
(If your output looks like this your ready to go!!! CL Platform 0 vendor: Advanced Micro Devices, Inc. CL Platform 0 name: AMD Accelerated Parallel Processing CL Platform 0 version: OpenCL 1.2 AMD-APP (1214.3) Platform 0 devices: 1 0 Tahiti GPU 0 AMD Radeon HD 7900 Series hardware monitoring enabled 1 GPU devices max detected)
*20. Excellent! Now we have it installed, its time to pick 2-3 pools, and get accounts set up at each of them. I currently use These 2, and If I find another I like I'll update. If you have a really awesome pool you would like me to include on the list, feel free to message me.
Pools: http://doge.cryptovalley.com/ (great community, server not super stable, but they have a chat. I hang out here a lot under the handle 'StrongBad' feel free to stop buy and ask questions)
https://dogehouse.org/ (Super stable pool, Great contests, super friendly, and they pay your miner a bonus if you find the block!)
Choose your pools, go to their sites and sign up. VERY IMPORTANT!!! Use different usernames and passwords for every mining site. If one site gets hacked, you don't want to give them a way to steal everything!!!!! Don't worry about the worker names and passwords being unique or complex tho, the most they can do with this is mine for you.
*21. Ok, now go to the CGminer folder, and open up a Terminal Window.
{sudo ./cgminer} 
This should start ./cgminer up with some really basic settings, and not pointed at any pool. Lets fix that: First press [p] to go to pool settings Now [A] and enter the information for the 1st pool. For instance if you are signing on for dogehouse: (Input server details: stratum+tcp://stratum.dogehouse.org:3333 Username: 'yourusername.workername password: 'yourpassword') If you got no errors, you did it right! Your miner should now connect and start to mine very slowly.
