                Bitcore是BitPay提供的一套工具。 其目標是為Bitcoin開發人員提供易于使用的工具。 幾乎所有的Bitcore的代碼都是用JavaScript編寫的。 有一些專門為NodeJS編寫的模塊。 最后,Bitcore的“節點”模塊包括Bitcoin Core的C ++代碼。 有關詳細信息,請參閱[https://bitcore.io](https://bitcore.io/)。 # Bitcore的功能列表 Bitcoin full node \(bitcore-node\) Block explorer \(insight\) Block, transaction, and wallet utilities \(bitcore-lib\) Communicating directly with Bitcoin’s P2P network \(bitcore-p2p\) Seed entropy mnemonic generation(種子熵助記符) \(bitcore-mnemonic\) Payment protocol \(bitcore-payment-protocol\) Message verification and signing \(bitcore-message\) Elliptic curve Integrated Encryption Scheme(橢圓曲線綜合加密方案) \(bitcore-ecies\) Wallet service \(bitcore-wallet-service\) Wallet client \(bitcore-wallet-client\) Playground \(bitcore-playground\) Integrating services directly with Bitcoin Core \(bitcore-node\) # Bitcore庫示例 ## 先決條件 NodeJS &gt;= 4.x 或者使用[hosted online playground](https://bitcore.io/playground) 如果使用NodeJS和節點REPL: ``` $ npm install -g bitcore-lib bitcore-p2p $ NODE_PATH=$(npm list -g | head -1)/node_modules node ``` ## 使用bitcore-lib的錢包示例 使用關聯的私鑰創建新的比特幣地址: ``` > bitcore = require('bitcore-lib') > privateKey = new bitcore.PrivateKey() > address = privateKey.toAddress().toString() ``` 創建分層確定性私鑰和地址: ``` > hdPrivateKey = bitcore.HDPrivateKey() > hdPublicKey = bitcore.HDPublicKey(hdPrivateKey) > hdAddress = new bitcore.Address(hdPublicKey.publicKey).toString() ``` 從UTXO創建和簽署交易: ``` > 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) ``` 替換mempool中的最后一個交易(替換費): ``` > rbfTx = new Transaction() .from(utxo) .to(address, 35000) .fee(fee*2) .enableRBF() .sign(privateKeyOfUtxo); > tx.serialize(); > rbfTx.serialize(); ``` 將交易廣播到比特幣網絡(注意:僅廣播有效交易;請參閱[https://bitnodes.21.co/nodes](https://bitnodes.21.co/nodes)): 將以下代碼復制到名為broadcast.js的文件中。 tx和rbfTx變量分別是tx.serialize()和rbfTx.serialize()的輸出。 為了更換費用,對等人必須支持bitcoind選項mempoolreplace并將其設置為1。 運行文件節點broadcast.js: ``` 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(); ```
