Build Status Code Coverage Scrutinizer Code Quality Join the chat at https://gitter.im/Bit-Wasp/bitcoin-php

Requirements:

  • PHP 5.4+
  • Composer
  • ext-gmp
  • ext-mcrypt

Optional:

  • [secp256k1-php] - Install the secp256k1 PHP extension. Blazing speeds, but bleeding edge, beware.

##Installation You can install this library via Composer: composer require afk11/bitcoin or

    "require": "afk11\bitcoin"
}```

##Presently supported:

 - Blocks, block headers, basic mining, difficulty calculations
 - P2SH, Multisignature scripts.
 - ECDSA key creation, public & private key types. 
 - Transactions
 - Signature creation & verification 
 - Deterministic signatures (RFC6979)
 - BIP32 deterministic algorithms
 - Script builder, parser
 - RPC bindings to Bitcoin Core's RPC, getting OOP responses :)
 - Easy serialization to binary representation of most classes
 - SIGHASH types when creating transactions (not tested)
 - Payment Protocol (BIP70)

##Todo:
  - TransactionBuilder
  - Full script interpreter
  - SPV
  - P2P
  
## Implemented BIPs
  - BIP0016
  - BIP0032
  - BIP0070
  
# Examples  
## Generate private keys

// Create private keys use Afk11\Bitcoin\Key\PrivateKeyFactory;

$network = Bitcoin::GetNetwork(); $private = PrivateKeyFactory:create(true); $public = $private->getPublicKey(); echo $private->getBuffer() . "\n"; echo $public->getBuffer() . "\n"; echo $public->getAddress($network) . "\n";


## Explore the blockchain using OOP bindings to the RPC

use Afk11\Bitcoin\Rpc\RpcFactory;

$bitcoind = RpcFactory::bitcoind('127.0.0.1', 18332, 'bitcoinrpc', 'BBpsLqmCCx7Vp8sRd5ygDxFkHZBgWLTTi55QwWgN6Ng6');

$hash = $bitcoind->getbestblockhash(); $block = $bitcoind->getblock($hash); $tx = $bitcoind->getTransactions()->getTransaction(10); echo $tx->getTransactionId();


## Create signed payment requests

use BitWasp\Bitcoin\Address\AddressFactory; use BitWasp\Bitcoin\PaymentProtocol\PaymentRequestBuilder; use BitWasp\Bitcoin\PaymentProtocol\PaymentRequestSigner; use BitWasp\Bitcoin\Script\ScriptFactory; use BitWasp\Bitcoin\Transaction\TransactionOutput;

$time = time(); $amount = 10000; $destination = '18Ffckz8jsjU7YbhP9P44JMd33Hdkkojtc'; $paymentUrl = 'http://192.168.0.223:81/bitcoin-php/examples/bip70.fetch.php?time=' . $time;

// Create a signer for x509+sha256 - this requires a readable private key and certificate chain. // $signer = new PaymentRequestSigner('none'); $signer = new PaymentRequestSigner('x509+sha256', '/var/www/git/paymentrequestold/.keys/ssl.key', '/var/www/git/paymentrequestold/.keys/ssl.pem'); $builder = new PaymentRequestBuilder($signer, 'main', time());

// PaymentRequests contain outputs that the wallet will fulfill $address = AddressFactory::fromString($destination); $builder->addAddressPayment($address, $amount);

// Create the request, send it + headers $request = $builder->send();
