Python比特币工具
项目描述
# Pybitcointools，Python比特币签名和交易的库
### 优点
函数接口简单，输入输出采用标准格式
无类
许多函数可以单独取出并使用
支持二进制、十六进制和Base58
交易反序列化格式几乎与BitcoinJS兼容
支持Electrum和BIP0032
制作和发布交易只需一条命令行指令
包括非比特币特定转换和JSON实用工具
### 缺点
不是全节点，不知道什么是区块
依赖于集中式服务（blockchain.info）进行区块链操作，尽管操作有备份（eligius, blockr.io）
### 示例用法（学习最佳方式 :)）
从bitcoin导入所有内容 > priv = sha256('some big long brainwallet password') > priv '57c617d9b4e1f7af6ec97ca2ff57e94a28279a7eedd4d12a99fa11170e94f5a4' > pub = privtopub(priv) > pub '0420f34c2786b4bae593e22596631b025f3ff46e200fc1d4b52ef49bbdc2ed00b26c584b7e32523fb01be2294a1f8a5eb0cf71a203cc034ced46ea92a8df16c6e9' > addr = pubtoaddr(pub) > addr '1CQLd3bhw4EzaURHbKCwM5YZbUQfA4ReY6' > h = history(addr) > h [{'output': u'97f7c7d8ac85e40c255f8a763b6cd9a68f3a94d2e93e8bfa08f977b92e55465e:0', 'value': 50000, 'address': u'1CQLd3bhw4EzaURHbKCwM5YZbUQfA4ReY6'}] > outs = [{'value': 90000, 'address': '16iw1MQ1sy1DtRPYw3ao1bCamoyBJtRB4t'}] > tx = mktx(h,outs) > tx '01000000025e46552eb977f908fa8b3ee9d2943a8fa6d96c3b768a5f250ce485acd8c7f7970000000000ffffffff71d1abe4352100d4d837ca96c1a16947b5444f0f3e0bc645c430f704bb06c84c0100000000ffffffff01905f0100000000001976a9143ec6c3ed8dfc3ceabcc1cbdb0c5aef4e2d02873c88ac00000000' > tx2 = sign(tx,0,priv) > tx2 '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' > tx3 = sign(tx2,1,priv) > tx3 '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' > pushtx(tx3) 'Transaction Submitted'
