Bitcore库示例
先决条件
NodeJS >= 4.x 或者使用hosted online playground
如果使用NodeJS和节点REPL：
|
1 2 3 |
$ npm install -g bitcore-lib bitcore-p2p $ NODE_PATH=$(npm list -g | head -1)/node_modules node |
使用bitcore-lib的钱包示例
使用关联的私钥创建新的比特币地址：
|
1 2 3 4 |
> bitcore = require('bitcore-lib') > privateKey = new bitcore.PrivateKey() > address = privateKey.toAddress().toString() |
创建分层确定性私钥和地址：
|
1 2 3 4 |
> hdPrivateKey = bitcore.HDPrivateKey() > hdPublicKey = bitcore.HDPublicKey(hdPrivateKey) > hdAddress = new bitcore.Address(hdPublicKey.publicKey).toString() |
从UTXO创建和签署交易：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 |
> utxo = { txId: transaction id containing an unspent output, outputIndex: output indexi e.g. 0, address: addressOfUtxo, script: bitcore.Script.buildPublicKeyHashOut(addressOfUtxo).toString(), satoshis: amount sent to the address } > fee = 3000 //set appropriately for conditions on the network > tx = new bitcore.Transaction() .from(utxo) .to(address, 35000) .fee(fee) .enableRBF() .sign(privateKeyOfUtxo) |
替换mempool中的最后一个交易（替换费）：
|
1 2 3 4 5 6 7 8 9 |
> rbfTx = new Transaction() .from(utxo) .to(address, 35000) .fee(fee*2) .enableRBF() .sign(privateKeyOfUtxo); > tx.serialize(); > rbfTx.serialize(); |
将交易广播到比特币网络（注意：仅广播有效交易;请参阅https://bitnodes.21.co/nodes）：
将以下代码复制到名为broadcast.js的文件中。
tx和rbfTx变量分别是tx.serialize（）和rbfTx.serialize（）的输出。
为了更换费用，对等人必须支持bitcoind选项mempoolreplace并将其设置为1。
运行文件节点broadcast.js：
|
1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 |
var p2p = require('bitcore-p2p'); var bitcore = require('bitcore-lib'); var tx = new bitcore.Transaction('output from serialize function'); var rbfTx = new bitcore.Transaction('output from serialize function'); var host = 'ip address'; //use valid peer listening on tcp 8333 var peer = new p2p.Peer({host: host}); var messages = new p2p.Messages(); peer.on('ready', function() { var txs = [messages.Transaction(tx), messages.Transaction(rbfTx)]; var index = 0; var interval = setInterval(function() { peer.sendMessage(txs[index++]); console.log('tx: ' + index + ' sent'); if (index === txs.length) { clearInterval(interval); console.log('disconnecting from peer: ' + host); peer.disconnect(); } }, 2000); }); peer.connect(); |
