How to Build A Crypto Trading Platform #2: Bitcoin Wallet

Groestlcoin 6th Anniversary Release

Introduction

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

UPDATED - Groestlcoin Core 2.18.2

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

ALL NEW - Groestlcoin Moonshine iOS/Android Wallet

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

ALL NEW! – HODL GRS Android Wallet

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

ALL NEW! – GroestlcoinSeed Savior

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

ALL NEW! – Vanity Search Vanity Address Generator

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

ALL NEW! – 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).

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

Groestlcoin WPF is an alternative full node client with optional lightweight 'thin-client' mode based on WPF. Windows Presentation Foundation (WPF) is one of Microsoft's latest approaches to a GUI framework, used with the .NET framework. Its main advantages over the original Groestlcoin client include support for exporting blockchain.dat and including a lite wallet mode.
This wallet was previously deprecated but has been brought back to life with modern standards.

ALL NEW! – Electrum Personal Server

Groestlcoin Electrum Personal Server aims to make using Electrum Groestlcoin wallet more secure and more private. It makes it easy to connect your Electrum-GRS wallet to your own full node.
It is an implementation of the Electrum-grs server protocol which fulfils the specific need of using the Electrum-grs wallet backed by a full node, but without the heavyweight server backend, for a single user. It allows the user to benefit from all Groestlcoin Core's resource-saving features like pruning, blocks only and disabled txindex. All Electrum-GRS's feature-richness like hardware wallet integration, multi-signature wallets, offline signing, seed recovery phrases, coin control and so on can still be used, but connected only to the user's own full node.
Full node wallets are important in Groestlcoin because they are a big part of what makes the system be trust-less. No longer do people have to trust a financial institution like a bank or PayPal, they can run software on their own computers. If Groestlcoin is digital gold, then a full node wallet is your own personal goldsmith who checks for you that received payments are genuine.
Full node wallets are also important for privacy. Using Electrum-GRS under default configuration requires it to send (hashes of) all your Groestlcoin addresses to some server. That server can then easily spy on your transactions. Full node wallets like Groestlcoin Electrum Personal Server would download the entire blockchain and scan it for the user's own addresses, and therefore don't reveal to anyone else which Groestlcoin addresses they are interested in.
Groestlcoin Electrum Personal Server can also broadcast transactions through Tor which improves privacy by resisting traffic analysis for broadcasted transactions which can link the IP address of the user to the transaction. If enabled this would happen transparently whenever the user simply clicks "Send" on a transaction in Electrum-grs wallet.
Note: Currently Groestlcoin Electrum Personal Server can only accept one connection at a time.

UPDATED – Groestlcoin Sentinel 3.5.06 (Android)

Groestlcoin Sentinel is a great solution for anyone who wants the convenience and utility of a hot wallet for receiving payments directly into their cold storage (or hardware wallets).
Sentinel accepts XPUB's, YPUB'S, ZPUB's and individual Groestlcoin address. Once added you will be able to view balances, view transactions, and (in the case of XPUB's, YPUB's and ZPUB's) deterministically generate addresses for that wallet.
Groestlcoin Sentinel is a fork of Groestlcoin Samourai Wallet with all spending and transaction building code removed.

[DEVELOPMENT] Bitcoind IPV4 testnet port (18332) is failing to bind

[SOLVED] Thanks for everyone that have helped!


Hello everyone, this is a development problem that I'm currently having. Since the BTC Development sub is kind of inactive and I couldn't find any rule contraty to posting about BTC Development, I'll try my luck in here as I'm hopeless already. I've posted on BTC Stack Exchange but no answers also. Please, don't get me wrong, I'm trying to solve this problem for many days now, I've looked up everywhere for this.
I'm new to Bitcoin development and I'm currently having difficulties trying to make RPC calls from a Docker Container to a Bitcoin-Core daemon running in a SSH server. I suppose that the problem may be with Firewall or closed ports, but I also do not know much about Network settings.
I'm using nbobtc/bitcoind-php package to make the RPC calls with HTTP requests, and it is running in a Docker container. I'm sure the container is functional and is not the problem.
So here's what happening: when I run bitcoind in root user (but normal also won't work) in my SSH server, the IPV4 testnet port seems to be not opened. This message goes up when I run bitcoind:
Binding RPC on address 0.0.0.0 port 18332 failed.
Here's what my bitcoin.conf looks like (I want to use testnet in here). I'm using Bitcoin-Core "subversion": "Satoshi:0.17.1".
server=1 debug=net txindex=1 testnet=1 rpcuser=userb rpcpassword=test test.rpcport=18332 # I've already tried allowing the IP these 3 ways: # rpcallowip=192.168.xx.xx # My machine's IP # rpcallowip=172.19.x.x/xx # Docker's NBOBTC container IP # rpcallowip=0.0.0.0/0 # Allowing all IP datadir=/home/bitcoin-dev/.bitcoin debuglogfile=/home/bitcoin-dev/.bitcoin/debug.log 
Here's what appears in debug.log right after I run Bitcoind:

After all that appears above, there are just "UpdateTip", "Requesting block", "received block" and "getdata" messages. (so the P2P port, 18333, works).

And here is when I netstat:

sudo netstat -nap|grep bitcoin|grep LISTEN

Thank you in advance!

PS: A few days ago I could make it work when running bitcoind with root user, but now even that won't solve the problem.

Step by step in staking Redd with Raspberry Pi 3

Before I start, I would like to pay complete credits to these two guys :)
https://www.reddcointalk.org/topic/2679/reddcoin-staking-via-ubuntu-mate-on-raspberry-pi-3-model-b-march-2018 (most of my steps, if not all, are from this link)
https://github.com/joroob/reddcoin/blob/mastedoc/build-arm.md
All the steps I am writing is ABSOLUTELY NECESSARY, please don't try to skip it because I did, and it doesn't work.
step 1: get a Raspberry Pi B https://www.raspberrypi.org/products/#buy-now-modal
step 2: make sure you get proper power supply 5v 2A - the Pi will mine, it will need sufficient power. Regular USB samsung charger will not work.
step 3: get proper micro SD card (SanDisk for example) 32Gb++
step 4: USB + Mouse keyboard
step 5: flash micro SD card with Ubuntu MATE
Download Ubuntu Mate image: https://ubuntu-mate.org/raspberry-pi/
Download Etcher: https://etcher.io
After finishing downloading, use Etcher to write/flash the image on micro SD card
After this, your SD card contains Ubuntu MATE OS.
step 6: Place SD Card into Raspberry Pi 3 and start it up. You should be able to see Ubuntu OS! Congrats!
step 7: Connect to wifi or internet cable (internet is better and faster)
step 8: OPTIONAL - turn off UI OS, so that things will work faster
Open XTerminal:
sudo systemctl disable lightdm.service (to turn UI off) 
in case you want to turn UI on again, run this:
sudo systemctl start lightdm.service (to turn UI on) 
step 9: install all dependencies
sudo apt-get update && sudo apt-get install git build-essential libqt4-dev libprotobuf-dev protobuf-compiler libtool autotools-dev autoconf libssl-dev libboost-all-dev wget pkg-config sudo add-apt-repository ppa:bitcoin/bitcoin sudo apt-get update sudo apt-get install db4.8 sudo apt-get install libminiupnpc-dev sudo apt-get install libqrencode-dev Reboot 
step 10: add additional RAM (sort of) in case the App need it, this is call "Create Swap file"
sudo fallocate -l 1G /swapfile sudo chmod 600 /swapfile sudo mkswap /swapfile sudo swapon /swapfile echo ‘/swapfile none swap sw 0 0’ | sudo tee -a /etc/fstab 
step 11: Build Berkeley Database
wget http://download.oracle.com/berkeley-db/db-4.8.30.NC.tar.gz tar xfvz db-4.8.30.NC.tar.gz cd db-4.8.30.NC cd build_unix ../dist/configure --enable-cxx make sudo make install 
step 11.5: Set BerkeleyDB path
export CPATH="/uslocal/BerkeleyDB.4.8/include" export LIBRARY_PATH="/uslocal/BerkeleyDB.4.8/lib" export LD_LIBRARY_PATH=/uslocal/BerkeleyDB.4.8/lib/ 
step 12: Build Reddcoin Wallet
---download source code ---- only source from joroob/reddcoin will work because some stweak was needed for ARM CPU
cd ~ git clone https://github.com/joroob/reddcoin.git 
---build reddcoin ----
cd reddcoin ./autogen.sh ./configure --with-gui=no --disable-tests cd src make sudo make install 
If you finish this, you are in a great position!!!
step 13: Create reddcoin configuration file
cd ~ mkdir .reddcoin && cd .reddcoin nano reddcoin.conf rpcuser=YOUR OWN USERNAME, YOU DONT NEED TO REMEMBER THIS, MAKE IT AS LONG AS YOU WANT rpcpassword=YOUR OWN PASS WORD, YOU DONT NEED TO REMEMBER THIS, MAKE IT AS LONG AS YOU WANT 
step 14: Use bootstrap
(At this point, you had a running reddcoin daemon, now you can start staking. But syncing the full chain takes long time.)
cd ~/.reddcoin wget https://github.com/reddcoin-project/reddcoin/releases/download/v2.0.1.2/bootstrap.dat.xz xz -d bootstrap.dat.xz 
step 15: start the reddcoin daemon service cd ~/reddcoin/src ./reddcoind -daemon
After this, you can test if the daemon is working, by perform this command: ./reddcoin-cli getblockcount
step 16: if your app is not able to sync, it is probably the firewall issue with OS, run this to allow port 45444 (used by Reddcoin) and redo step 15
sudo iptables -I INPUT 1 -i eth0 -p tcp --dport 45444 -j ACCEPT sudo iptables -A OUTPUT -p tcp --dport 45444 -j ACCEPT 
step 17: open BEER and enjoy! This is a MUST or the daemon will stop working! I am not kidding!
step 18: Actually, i forgot to mention you need to execute this command for the wallet to stake:
reddcoind walletpassphrase $yourpassword 9999999 true 
ADDITIONAL REMARKS:
From my PC: I am using putty to execute the command, winSCP to monitor the file location on raspberry.
Moving Red Coins out of exchange really a big move, start with normal wallet, don't start with this tutorial :) Ever since I move my coins out of exchange, I am free from all of the ups and downs! Really!
So guys and gals, Redd On!
UPDATE 18 Mar: my first stake has arrived after 6 days staking :)
In case you want to tip me: RaF3TeWqgTzAdnaZQffnsxS74dag13zsAY
Edit 1: Format stuff
Edit 2: Add step 18 to execute staking command.
Edit 3: In case you don't want to compile the source code, you can download my compile version here: https://github.com/hieplenet/reddcoin/releases/tag/v2.0.0.0 (but doing this, you should be aware of the risk of me changing source code for my benefit - I don't change any thing, but you should be cautious, this is the internet :) )

Interested in contributing to the BTC network? Here is the steps to get a full node up and running in Linux.

These instructions will work both on a VPS cloud server or a personal computer. You may find cheap VPS somewhere online for rent.
What Is A Full Node?
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

If the BiblePay isnt already running, run it
cd home/username/biblepay/src ./biblepayd -daemon -txindex 
If Explorer isnt already running, run it
cd home/username/explorer npm start 
Recommendation:*
Add these parameters to biblepay.conf file
daemon=1 txindex=1 
Extra: This Iquidis for Dummides guide also adds: https://gist.github.com/zeronug/5c66207c426a1d4d5c73cc872255c572
Upstart, to have MongoDB auto start after reboots
Forever, to make sure Explorer is always running
Install Forever to keep the js running # sudo npm install forever -g # sudo npm install forever-monitor Start the Explorer # forever start bin/cluster 
Nginx - Reverse Proxy Port 3001 to 80 https://eladnava.com/binding-nodejs-port-80-using-nginx/
BiblePay Daemon set to run Every 2 Minutes with Cron
sudo crontab -e */2 * * * * /home/biblepay/src/biblepayd > /dev/null 2>&1 
Note: In ~/.biblepaycore/biblepay.conf add daemon=1 and txindex=1 Note: > /dev/null 2>&1 will capture both STDOUT (1) and STDERR (2) and send them to /dev/null
Auto Remove index.pid if indexing is complete
#!/bin/bash fname="/home/biblepay/exploretmp/index.pid" if [[ -f "$fname" ]]; then pid=$( /dev/null r=$? echo $r if [ $r -eq 0 ]; then exit 1 else rm $fname fi fi 
-f is checking if the file exists index.pid is the indexing lock file with its process ID number inside of it ps -p checks if the process is running $? is the value of the last output that ran and since the previous value is going to dev/null, its the exit code status "0 for successful executions and 1 or higher for failed executions." and so if the process is still running, the bash script just exits, otherwise the process is done and the index.pid file gets removed the file doesnt need a .sh extension, if you have "#!/bin/bash" at the top then linux knows its a bash script chmod +x to set it as executable

BronyCoin ( Cryptocurrency )

This is a pre-release post to gather opinions from fellow Bronies. What do I need your opinions on? just about everything really 1) Do you agree with the amount of currency been mined yearly? 2) Do you think we can achieve better than the Doge meme community did with their currency? 3) Do you like the PoS/PoW advanced hybrid system or pure POW? 4) Do you think half the supply of Dogecoin is okay, or should we go even rarer supply with our currency? 5) Do you think merchants at Bronycon and other conventions would accept the currency as payment? 6) Would you use Bronycoin to tip your friends for art work and stuff? 7) Do you think the sub units 100 million parts that make up 1 Bronycoin, should be called Pegasisters or Bits?? 8) what do you believe is best way to insure only Bronies get free currency??? This is a mock up of this release post o_O note no download links or source till we're ready, but if you wish to test a crypto wallet to see what the competition has, Id say try Dogecoin as that's the currency we'll be looking to take over in market share. Bronycoin (BRO) like with the satoshi parts in a Bitcoin, the 100 million parts that make up each Bronycoin will be called Bits, Bits for short :) so 100 million Bits = 1 Bronycoin (Brony) Why Bronycoin? Because first of all, we don't like central banks and corrupt governments, and would love to see them lose the monopoly, Why shouldn't Bronies create and control our own currency? Bronycoin's goal is to be used for tipping other Bronies for Artwork and Fun on forums, social networks, darknets like I2P, Tor and others, as well as the normal Internet (clearnet) At the current moment it works with SOCKS over I2P/Tor. Native support for I2P should be in place soon. Its an advanced NeoScrypt PoW/PoS coin, and has some other nice features too. Such as transaction messaging and been (Turning complete) But the main feature is the large community of Bronies, something Doge could only dream of :eek: why should doge go down as the greatest meme in history just because somebody made a cryptocurrency of it??? Bronies create more memes daily than any dogers. Proof-Of-Stake Bronycoin's major distinguishing feature is that it uses proof-of-stake/proof-of-work hybrid system. The proof-of-stake system was designed to address vulnerabilities that could occur in a pure proof-of-work system. For example, there is a risk of 51% attacks in Bitcoin or Litecoin and Dogecoin resulting from a monopoly on mining power (a 51% attack is when a single entity possesses over a half of the network hash power), which would possibly allow this entity to double spend coins. With a proof-of-stake system, a network attacker would also need to gain a large quantity of coins. This has the effect of making a monopoly more costly, and stops the risk of a monopoly from proof-of-work mining shares. Digital money made for the Internet Bronycoin was born from the Internet, bringing the freedom of physical money to the virtual world, while making payments easier and more secure in both worlds. Bronycoin can offer an alternative to previous cumbersome and costly systems, and it can increase online business access to developing countries, as well as helping to advance open source freedom, and the Brony community world wide. SPECIFICATIONS Advanced hybrid proof-of-work (PoW) and proof-of-stake (PoS) 50 billion coins to be produced block hashing is BLAKE2s PoW hashing is NeoScrypt PoS hashing is SHA-256d 1 minute combined block target (3 minutes for PoW, 1.5 minutes for PoS) Re targets every block Time warp and instamining protection Advanced check pointing against 51% attacks Transaction messaging supported 6 confirmations for regular transactions 200 confirmations for minted coins Very low transaction fees (most transactions are free) No destruction of transaction fees (all collected by a block finder) The default P2P port is 15298, RPC port is 15299 I2P/Tor ready POS INFORMATION PoW and PoS blocks carry the same fixed reward of 5 Brony one of the 1st implementation of a fixed PoS block rewards STATS / RANKINGS http://coinmarketcap.com/all.html http://www.whattomine.com/ not on sites yet.

About Heartbleed loopholes, as a bit of people , must be sensitive to , ah, brother of the first time I felt vulnerability unlimited , ideas unlimited , unlimited play , as to get rid of xxx, it needs Martian guts , brother still relatively conservative , but in another way detour and the line, this is just to let you experience the next :
Steps are as follows :
1 find various bits coins, currency cottage client IP address , find a specific port, which enable SSL
Get bitcoin client ip installed two ways :
1 Download a qt-bitcoin client, open debug.log, ok it collects inside IP

https://bitcoin.org/en/alert/2014-04-11-heartbleed
OpenSSL Heartbleed vulnerability 11 April 2014What happened The version of OpenSSL used by Bitcoin Core software version 0.9.0 and earlier contains a bug that can reveal memory to a remote attacker. See http://heartbleed.com/ for details. What you should do Immediately upgrade to Bitcoin Core version 0.9.1 which is linked against OpenSSL version 1.0.1g. If you use the official binaries, you can verify the version of OpenSSL being used from the Bitcoin Core GUI's Debug window (accessed from the Help menu). If you compiled Bitcoin Core yourself or use the Ubuntu PPA, update your system's OpenSSL. Linux users should also upgrade their system's version of OpenSSL. Android Android version 4.1.1 is vulnerable to Heartbleed. Try if you can upgrade to at least Android 4.1.2. If you are using Bitcoin Wallet on an Android phone, you should upgrade the app to at least version 3.45. How serious is the risk If you are using the Windows version of the Bitcoin Core GUI without a wallet passphrase, it is possible that your wallet could be compromised by clicking on a bitcoin:. Payment request link If you are using bitcoind (on Linux, OSX, or Windows) , have enabled the-rpcssl option, and allow RPC connections from the Internet, an attacker from a whitelisted (-allowip) IP address can very likely discover the rpcpassword and the last rpc request. It is possible (but unlikely) private keys could be sent to the attacker.

INCAKOIN. Creating a SAFE and environmentally sound future for the children of the world :D
Many newcomers and some of the early adopters might be asking themselves “Why INCAKOIN? Whats so special about incakoin?”….. Well I’ll tell you.
1.) Early adoption.
INCAKOIN is rounding post beta. INCAKOIN’S dev’s have worked out the bugs. INCA survived a 51% attack which we are very proud of doing. Checkpoint servers have been installed. What this means is even IF incakoin were to experience a 51% attack developers can rewind the blockchain ( The platform in which carries out transactions on the network. ) back to the time of attack and recommence mining right before the time of the attack. A fix for the malleability issue bitcoin has been facing. CRUCIAL due to the rouge nature of data mining. The server acts as a SAFEGUARD so that no one group or entity can control the blockchain or all the coin supply. This is a very good thing and is unique to INCAKOIN.. The Proof of Stake give’s INCA the ability to verify transactions and new coin creation with older mature coins. Another fix for the transaction malleability exploit facing previous forms of CryptoCurrencies. Genius if you ask me. Good work DEV’s. Most SECURE CryptoCurrency. Making us MORE secure than Bitcoin by LIGHT YEARS :D
2.) Fair supply
We came into the game with the question “Why would 21 Million of something be fair for a GLOBAL economy?” Answer: It wouldn’t. Bitcoin is not a fairly distributed currency. 21 million units divisible by how ever many times it can be divided will still NOT be fairly distributed currency. Especially with Bitcoin early adopters holding many of the coins already. Its like saying “I have money because I’m SMARTER than you. I had INVESTED when you didn’t know and I didn’t bother to TELL YOU because it was INSIDE information”…. If this was Wall Street bitcoin would be Enron. Its unforgivable. INCAKOIN however is very transparent about its activities. We feel as though that withholding information about us or how we operate is not something we are willing to do. That’s why we remain transparent. Keeps us honest. 190 million INCA coins are a very reasonable number as far as supply of digital gold. This number better reflects the worlds supply of gold if we choose for it to be the basis of our backing. The network is setup for rapid growth and hashrate. So jump right in and mine with us. You’ll make a FORTUNE :D
3.) Because we CARE :)
We care about the world and people. INCAKOIN is friendly to the environment. With our model of mining we use way less electricity and we do so with pride. Being a Hybrid Proof of Stake and Proof of Work coin enables us to use way less electricity than the BEAST that Bitcoin has become. It is our obligation as responsible adults to create a future that we would want our children and our children’s children to grow up in when we are gone. To do anything else would be SELFISH! We encourage everyone who mines INCAKOIN to be as eco friendly as possible. Solar, Wind, and Water powered energy if you have the means.
On that note that’s what make us special. INCAKOIN is advanced and a hybrid of CryptoCurrency. We have the fix already in place that Bitcoin lacks concerning transaction malleability. We are the future and the future is made of INCA gold.

Interested in contributing to the BTC community? Here is a exhaustive manual to get you up and running. (Only takes about 20-30 minutes if you are fluent in command prompt on linux).

These instructions will work both on a VPS cloud server or a personal computer. You may find cheap VPS somewhere online for rent.
What Is A Full Node?
A full node is a program that fully validates transactions and blocks. Almost all full nodes also help the network by accepting transactions and blocks from other full nodes, validating those transactions and blocks, and then relaying them to further full nodes.
Most full nodes also serve lightweight clients by allowing them to transmit their transactions to the network and by notifying them when a transaction affects their wallet. If not enough nodes perform this function, clients won’t be able to connect through the peer-to-peer network—they’ll have to use centralized services instead.
Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

Many people and organizations volunteer to run full nodes using spare computing and bandwidth resources—but more volunteers are needed to allow Bitcoin to continue to grow. This document describes how you can help and what helping will cost you.
Costs And Warnings
Running a Bitcoin full node comes with certain costs and can expose you to certain risks. This section will explain those costs and risks so you can decide whether you’re able to help the network.
Special Cases
Miners, businesses, and privacy-conscious users rely on particular behavior from the full nodes they use, so they will often run their own full nodes and take special safety precautions. This document does not cover those precautions—it only describes running a full node to help support the Bitcoin network in general.
Please consult an expert if you need help setting up your full node correctly to handle high-value and privacy-sensitive tasks.
Secure Your Wallet
It’s possible and safe to run a full node to support the network and use its wallet to store your bitcoins, but you must take the same precautions you would when using any Bitcoin wallet. Please see the securing your wallet page for more information.
Minimum Requirements
Bitcoin Core full nodes have certain requirements. If you try running a node on weak hardware, it may work—but you’ll likely spend more time dealing with issues. If you can meet the following requirements, you’ll have an easy-to-use node.
Note: many operating systems today (Windows, Mac, and Linux) enter a low-power mode after the screensaver activates, slowing or halting network traffic. This is often the default setting on laptops and on all Mac OS X laptops and desktops. Check your screensaver settings and disable automatic “sleep” or “suspend” options to ensure you support the network whenever your computer is running.
Possible Problems
Legal: Bitcoin use is prohibited or restricted in some areas.
Bandwidth limits: Some Internet plans will charge an additional amount for any excess upload bandwidth used that isn’t included in the plan. Worse, some providers may terminate your connection without warning because of overuse. We advise that you check whether your Internet connection is subjected to such limitations and monitor your bandwidth use so that you can stop Bitcoin Core before you reach your upload limit.
Anti-virus: Several people have placed parts of known computer viruses in the Bitcoin block chain. This block chain data can’t infect your computer, but some anti-virus programs quarantine the data anyway, making it more difficult to run a full node. This problem mostly affects computers running Windows.
Attack target: People who want to disrupt the Bitcoin network may attack full nodes in ways that will affect other things you do with your computer, such as an attack that limits your available download bandwidth or an attack that prevents you from using your full node’s wallet for sending transactions.
Linux Instructions
The following instructions describe installing Bitcoin Core on Linux systems.
Ubuntu 14.10 Instructions for Bitcoin Core 0.10.0.
If you use Ubuntu Desktop, click the Ubuntu swirl icon to start the Dash and type “term” into the input box. Choose any one of the terminals listed:
Alternatively, access a console or terminal emulator using another method, such as SSH on Ubuntu Server or a terminal launcher in an alternative desktop environment.
Type the following line to add the Bitcoin Personal Package Archive (PPA) to your system:
sudo apt-add-repository ppa:bitcoin/bitcoin
You will be prompted for your user password. Provide it to continue. Afterwards, the following text will be displayed:
Stable Channel of bitcoin-qt and bitcoind for Ubuntu, and their dependencies
More info: https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin
Press [ENTER] to continue or ctrl-c to cancel adding it
Press enter to continue. The following text (with some variations) will be displayed and you will be returned to the command line prompt:
gpg: keyring /tmp/tmpixuqu73x/secring.gpg' created gpg: keyring/tmp/tmpixuqu73x/pubring.gpg' created gpg: requesting key 8842CE5E from hkp server > > > >keyserver.ubuntu.com gpg: /tmp/tmpixuqu73x/trustdb.gpg: trustdb created gpg: key 8842CE5E: public key "Launchpad PPA for Bitcoin" imported gpg: no ultimately trusted keys found gpg: Total number processed: 1 pg: imported: 1 (RSA: 1) OK
Type the following line to get the most recent list of packages:
sudo apt-get update
A large number of lines will be displayed as different update files are downloaded. This step may take several minutes on a slow Internet connection.
To continue, choose one of the following options
sudo apt-get install bitcoin-qt
sudo apt-get install bitcoind
sudo apt-get install bitcoin-qt bitcoind
After choosing what packages to install, you will be asked whether you want to proceed. Press enter to continue.
If you’re logged in as an administrative user with sudo access, you may log out. The steps in this section should be performed as the user you want to run Bitcoin Core. (If you’re an expert administrator, you can make this a locked account used only by Bitcoin Core.)
Before using the Bitcoin Core daemon, bitcoind, you need to create its configuration file with a user name and password. First create the .bitcoin directory, create (touch) the file, and set the file’s permissions so that only your user account can read it. From the terminal, type:
mkdir ~/.bitcoin touch ~/.bitcoin/bitcoin.conf chmod 600 ~/.bitcoin/bitcoin.conf
Then you can run the command bitcoind. It will print output similar to this:
bitcoind Error: To use the "-server" option, you must set a rpcpassword in the configuration file: /home/bitcoinorg/.bitcoin/bitcoin.conf It is recommended you use the following random password: rpcuser=bitcoinrpc rpcpassword=XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX (you do not need to remember this password)
The username and password MUST NOT be the same.
If the file does not exist, create it with owner-readable-only file permissions. It is also recommended to set alertnotify so you are notified of problems; for example: alertnotify=echo %s | mail -s "Bitcoin Alert" [email protected] The “rpcpassword” displayed will be unique for your system. You can copy the rpcuser and rpcpassword lines into your configuration file using the following commands. Note that in most Ubuntu terminals, you need to press Ctrl-Shift-C to copy and Ctrl-Shift-V to paste because Ctrl-C and Ctrl-V have different meanings in a Unix-style terminal.
echo rpcuser=bitcoinrpc >> ~/.bitcoin/bitcoin.conf echo rpcpassword=XXXXXX >> ~/.bitcoin/bitcoin.conf (Warning: Don’t use XXXXXX as your RPC password. Copy the rpcpassword displayed by bitcoind for your system.)
Now you can start Bitcoin Core daemon for real. Type the following command:
bitcoind -daemon
It will print a message that Bitcoin Core is starting. To interact with Bitcoin Core daemon, you will use the command bitcoin-cli (Bitcoin command line interface). Note: it may take up to several minutes for Bitcoin Core to start, during which it will display the following message whenever you use bitcoin-cli:
error: {"code":-28,"message":"Verifying blocks..."}
After it starts, you may find the following commands useful for basic interaction with your node:
to safely stop your node, run the following command:
bitcoin-cli stop
A complete list of commands is available in the Bitcoin.org developer reference.
When Bitcoin Core daemon first starts, it will begin to download the block chain. This step will take at least several hours, and it may take a day or more on a slow Internet connection or with a slow computer. During the download, Bitcoin Core will use a significant part of your connection bandwidth. You can stop Bitcoin Core at any time using the stop command; it will resume from the point where it stopped the next time you start it.
Optional: Start Your Node At Boot
Starting your node automatically each time your computer boots makes it easy for you to contribute to the network. The easiest way to do this is to start Bitcoin Core daemon from your crontab. To edit your crontab, run the following command:
crontab -e
@reboot bitcoind -daemon Save the file and exit; the updated crontab file will be installed for you. Now Bitcoin Core daemon will be automatically started each time your reboot your computer.
If you’re an Ubuntu expert and want to use an init script instead, see this Upstart script.
You have now completed installing Bitcoin Core. If you have any questions, please ask in one of Bitcoin’s many communities, such as Bitcoin StackExchange, BitcoinTalk technical support, or the #bitcoin IRC chatroom on Freenode.
To support the Bitcoin network, you also need to allow incoming connections. Please read the Network Configuration section for details.
Network Configuration
If you want to support the Bitcoin network, you must allow inbound connections.
When Bitcoin Core starts, it establishes 8 outbound connections to other full nodes so it can download the latest blocks and transactions. If you just want to use your full node as a wallet, you don’t need more than these 8 connections—but if you want to support lightweight clients and other full nodes on the network, you must allow inbound connections.
Servers connected directly to the Internet usually don’t require any special configuration. You can use the testing instructions below to confirm your server-based node accepts inbound connections.
Home connections are usually filtered by a router or modem. Bitcoin Core will request your router automatically configure itself to allow inbound connections to Bitcoin’s port, port 8333. Unfortunately many routers don’t allow automatic configuration, so you must manually configure your router. You may also need to configure your firewall to allow inbound connections to port 8333. Please see the following subsections for details.
Testing Connections
The BitNodes project provides an online tool to let you test whether your node accepts inbound connections. To use it, start Bitcoin Core (either the GUI or the daemon), wait 10 minutes, and then visit the GetAddr page (https://getaddr.bitnodes.io/). The tool will attempt to guess your IP address—if the address is wrong (or blank), you will need to enter your address manually.

MARSCOIN MRS
Currently, there are two attempts underway to establish the first human base on Mars. While technologically not impossible funding such a project (estimated at 6-20 billion) is a major obstacle. If you share our dream of making that first giant step for mankind a reality, then Marscoin might be something for you.
Simply by using Marscoin, a bitcoin alternative, you will automatically participate in serious boostraping efforts to colonize Mars.
We donated 350,000 Marscoins to MarsOne, a non-profit that attempts to build the first colony on Mars. With your help - by adopting Marscoin - we will be able to help fund mankinds first colony on Mars simply by kickstarting the financial system of the future Mars colony!
In addition, once the colony is set up MarsOne or a Mars colonist could take Marscoin to Mars and install it. That means that your Marscoins would continue to be yours on Mars, forever.
