附录6、pycoin

    pycoin库支持Python 2（2.7.x）和Python 3（3.3之后），并附带一些方便的命令行实用程序ku和tx。

    命令行实用程序ku（“密钥实用程序”）是用于操纵密钥的瑞士军刀。 它支持BIP-32键，WIF和地址（比特币和代币）。 以下是一些例子。

    使用GPG和/ dev / random的默认熵源创建一个BIP-32密钥：

    从密码短语创建一个BIP-32密钥：

    警告 这个例子中的密码很容易猜到。

    哎呀！ 我们没有设置Web服务。 现在我们来做：

    1. $ PYCOIN_CACHE_DIR=~/.pycoin_cache
    2. $ PYCOIN_SERVICE_PROVIDERS=BLOCKR_IO:BLOCKCHAIN_INFO:BITEASY:BLOCKEXPLORER
    3. $ export PYCOIN_CACHE_DIR PYCOIN_SERVICE_PROVIDERS

    这不是自动完成的，所以命令行工具不会泄漏潜在的关于您对第三方网站感兴趣的交易的私人信息。 如果您不在乎，可以将这些行放入.profile。

    让我们再试一次：

    1. $ tx 49d2adb6e476fa46d8357babf78b1b501fd39e177ac7833124b3f67b17c40c2a

    14. ** can't validate transaction as source transactions missing

    出现最后一行是为了验证交易的签名，您技术上需要源代码交易。 所以我们来添加-a来增加源信息的交易：
