Find examples of how to build programs using Bitcoin.

The following guide aims to provide examples to help you start building Bitcoin-based applications. To make the best use of this document, you may want to install the current version of Bitcoin Core, either from source or from a pre-compiled executable.

Once installed, you’ll have access to three programs: bitcoind, bitcoin-qt, and bitcoin-cli.

bitcoin-qt provides a combination full Bitcoin peer and wallet frontend. From the Help menu, you can access a console where you can enter the RPC commands used throughout this document.

bitcoind is more useful for programming: it provides a full peer which you can interact with through RPCs to port 8332 (or 18332 for testnet).

bitcoin-cli allows you to send RPC commands to bitcoind from the command line. For example, bitcoin-cli help

All three programs get settings from bitcoin.conf in the Bitcoin application...

My connection is the same, there is no way that I am able to have incoming ports. A traceroute shows that, once the packet leaves my network, it will travel quite a distance on another private network before reaching an Internet IP.

My VPS in the USA doesn't have the disk space to handle the blockchain, so I'm fkd as far as running a full node goes. Maybe I will pay for a cloud node one day.

I also run bitcoin full nodes on VPSes. I chose to have multiple cheap VPSes in multiple datacenters, rather than one more expensive and presumably more reliable VPS. Because that gives me more capacity than needed, I also run bitcoind on all machines. If one or two VPSes go down at the same time (which hardly ever happens), I don't care about it too much. However, if that...

Do you want to use Bitcoin on Linux? This tutorial explains how to install and use Bitcoin Core on Debian Linux. Bitcoin Core is the official Bitcoin Wallet from I will use the latest version from the GIT repository at

In order to compile and run, Bitcoin Core depends on some other tools which must be installed prior to compiling :

Install some dependencies:

For bitcoin-core

sudo apt-get install build-essential autoconf libssl-dev libboost-dev libboost-chrono-dev libboost-filesystem-dev libboost-program-options-dev libboost-system-dev libboost-test-dev libboost-thread-dev

For bitcoin-qt (graphical interface)

If you want the graphical frontend, also install the following dependencies. If you just want bitcoind, you can skip this step.

sudo apt-get install libqt4-dev libprotobuf-dev protobuf-compiler libqrencode-dev

Installing Berkeley DB 4.8

Compiling Bitcoin Core requires the...

Download Bitcoin Client:

Full Client: "Do you have a computer that you keep switched on all the time, that's connected to the Internet? You can help the community by simply running the full Bitcoin client on it. The full client is more resource intensive and will take a complete day to synchronize. After that your computer will contribute to the network by checking and relaying transactions." [1]


Linux Client

Users Guide:


wget tar -zvxf bitcoin- cd bitcoin- ./bitcoind

Source Installation:

# sample from CentOS 6 - missing DB 4.8 yum install gcc make gcc-c++ autoconf automake libtool db4-devel git clone cd bitcoin ./ ./configure # NEED DB 4.8 make # sample from RaspberryPi # sudo apt-get install [from cgminer files??] # sudo apt-get install libdb4.8-dev...

The bitcoind package that is available in the universal Ubuntu repositories is a very old version. You could add the bitcoin PPA and then install bitcoind from that; this will get you a stable version of bitcoind that is at most a month or two old. But, if you're the extra careful type, it doesn't hurt your peace-of-mind to have built bitcoind from source yourself.

This tutorial assumes you've already built bitcoind from source. If you haven't done that, go ahead and do that now.


To get addaptrepository, which we will use later to add the bitcoin PPA:


Add the bitcoin PPA to get access to the libdb4dev package:

add-apt-repository ppa:bitcoin/bitcoin update

Now you can install all the dependencies:

libboost-all-dev libdb4.8-dev libdb4.8++-dev

If you're reading this from the future, you may want to check with the readme file(s) to verify that you have all the required dependencies; they may have...

What is Bitcoin?

Bitcoin is an experimental new digital currency that enables instant payments to anyone, anywhere in the world. Bitcoin uses peer-to-peer technology to operate with no central authority: managing transactions and issuing money are carried out collectively by the network. Bitcoin is also the name of the open source software which enables the use of this currency.

For more information, as well as an immediately useable, binary version of the Bitcoin client software, see

Before you delve into the process of creating an SMTP server for your small business, consider whether it requires a dedicated mail server for security, or if you can configure your messages to bounce off your ISP's server instead. SMTPs allow interoffice mailing and secure internal mail, and also provide secure external mail as long as they don't need to use your ISP's SMTP as a relay.

IIS SMTP Server Setup

1. Open up the Control Panel and click "Programs," or "Programs and Features" if you're in the Classic view.

2. Click "Turn Windows Features On or Off," which is located in the left pane if you're in Classic view. Click "Allow" if you get any security warnings.

3. Expand "Internet Information Services" and make sure that the "SMTP Server" is installed. If not, check the box next to it and restart as necessary.

4. Press the Windows key and "R" to open the Run menu. Type "inetmgr" and press "Enter" to open the IIS Manager.

Create the Primary Key.

It is highly recommended that you create a Primary Key as the first column on your table. This acts as an ID number, or record number, that will allow you to easily recall these entries later. To create this, enter "ID" in the Column Name field, type


into the Data Type field, and uncheck the "Allow Nulls." Click the Key icon in the toolbar to set this column as the Primary Key.

You don't want to allow null values because you always want the entry to be at least "1". If you allow nulls, your first entry will be "0". In the Column Properties window, scroll down until you find the Identity Specification option. Expand it and set "(ls Identity)" to "Yes". This will automatically increase the value of the ID column for each entry, effectively automatically numbering each new...

There are two variations of the original bitcoin program available; one with a graphical user interface (usually referred to as just “Bitcoin”), and a 'headless' version (called bitcoind). They are completely compatible with each other, and take the same command-line arguments, read the same configuration file, and read and write the same data files. You can run one copy of either Bitcoin or bitcoind on your system at a time (if you accidently try to launch another, the copy will let you know that Bitcoin or bitcoind is already running and will exit).

The simplest way to start from scratch with the command line client, automatically syncing blockchain and creating a wallet, is to just run this command (without arguments) from the directory containing your bitcoind binary:

These commands are accurate as of Bitcoin Core version v0.12.0rc1.

Fist you should encrypt your wallet:

bitcoin-cli encryptwallet 'yourpassphrasehere'

After that your bitcoind must synchronize with network(get all blocks)

Run command:

bitcoin-cli getinfo

and see how many blocks are synchronized:

{ "version": 130200, "protocolversion": 70015, "walletversion": 60000, "balance": 0.00455069, "blocks": 451571, < ------------------ "timeoffset": 0, "connections": 1, "proxy": "", "difficulty": 392963262344.3704, "testnet": false, "keypoololdest": 1485982350, "keypoolsize": 87610, "unlocked_until": 0, "paytxfee": 0.00000000, "relayfee": 0.00001000, "errors": "" }

If number of blocks is equal to this value:

you're ready to receive new payments.

if the amount is not equal, you can start bitcoind with option 'reindex' to force indexing blocks from the beginning.

Monitor your disk resources, because bitcoind need a lot of disk...
