示例代码：
//生成比特币地址 key = Bitcoin.ECKey.makeRandom() // Print your private key (in WIF format) console.log(key.toWIF()) // => 8c112cf628362ecf4d482f68af2dbb50c8a2cb90d226215de925417aa9336a48 // Print your public key (toString defaults to a Bitcoin address) console.log(key.pub.getAddress().toString()) // => 14bZ7YWde4KdRb5YN7GYkToz3EHVCvRxkF //开始交易 tx = new Bitcoin.Transaction() // Add the input (who is paying) of the form [previous transaction hash, index of the output to use] tx.addInput("aa94ab02c182214f090e99a0d57021caffd0f195a81c24602b1028b130b63e31", 0) // Add the output (who to pay to) of the form [payee's address, amount in satoshis] tx.addOutput("1Gokm82v6DmtwKEB8AiVhm82hyFSsEvBDK", 15000) // Initialize a private key using WIF key = Bitcoin.ECKey.fromWIF("L1uyy5qTuGrVXrmrsvHWHgVzW9kKdrp27wBC7Vs6nZDTF2BRUVwy") // Sign the first input with the new key tx.sign(0, key) // Print transaction serialized as hex console.log(tx.serializeHex()) // => 0100000001313eb630b128102b60241ca895f1d0ffca21 ... // You could now push the transaction onto the Bitcoin network manually (see https://blockchain.info/pushtx)
