Common Blockchain

Common Blockchain is a unified way to access a blockchain via an API provider. i.e. it provides the same methods and normalizes results no matter who the API provider is.

You'll need to bring your own Common Blockchain provider. Here's a list: https://github.com/common-blockchain/common-blockchain/issues/21

Example:

var Blockchain = require('cb-blockr')
var Spender = require('spender')
new Spender('testnet')      // network name ('bitcoin' or 'testnet')
  .blockchain(new Blockchain('testnet')) // common-blockchain provider
  .from(privateWif)         // string or bitcoinjs-lib's ECKey
  .to(toAddress, satoshis)  // string or bitcoinjs-lib's Address, int satoshis
  .fee(fee)                 // int satoshis
  .change(changeAddress)    // optional
  .data(data)               // optional (OP_RETURN)
  .execute(callback)        // calls back with (err, Transaction, utxosUsed)

Limitations

• bitcoin/testnet only at the moment
• simplified outputs
