The common libbitcoin library is a dependency of all others with the exception of libbitcoin-consensus. It was the first library created and originally contained the core functionality of all of the others.

Example
#include <iostream>
#include <string>
#include <bitcoin/bitcoin.hpp>
// Extract Satoshi's words.
int main()
{
const auto block = bc::genesis_block();
const auto& tx = block.transactions[0];
const auto& input = tx.inputs[0];
const auto script = bc::save_script(input.script);
std::string message(script.begin(), script.end());
std::cout << message << std::endl;

Bitcoin Related Features
- Key formats (raw, BIP32, WIF, compressed/uncompressed, minikey)
- Encoding functions (base 2/10/16/58/64/85)
- Hash functions (ripemd160, sha1, sha256, sha512, hmac_sha256, hmac_sha512, pkcs5_pbkdf2_hmac_sha512)
- URL parsing (BIP21 and BIP72)
- Mnemonic functions (BIP39)
- All published mnemonic dictionaries
- Curve math, deterministic ECDSA, verification and encryption functions
- Address functions (P2PKH and P2SH/BIP16),
- Stealth addresses functions[1] for wallets and blockchain search
- Wire and text serializable type library (P2P protocol)
- Bitcoin script engine (see libbitcoin-consensus for more information)
- Asynchronous P2P networking stack built on ASIO
General Purpose Features
- Logging utilities
- Patricia Trie template optimized for binary search
- UTF8 Everywhere tools and integration for Windows
- Command line, configuration file and help processing utilities
Build and Quality Control
- Autotools builds for GCC/Clang
- All build artifacts generated by libbitcoin-build
- Extensive unit text matrix (based on Boost Test)
- Continuous integration builds via Travis-CI
- Visual Studio 2013 project and solution files
- Support for 32/64 bit processors and endianness differences
- Uses C++11 advancements and restricts use of pointers and exceptions
Dependencies
- boost
- libsecp256k1
- ICU (optional)
