区块链爱好者（QQ：53016353）
区块链库起初由Richard Kiss 撰写和维护 ，基于 Python 脚本的处理交易密钥，不仅支持比特币交易，也支持其他非标准脚本语言的交易类型。
区块链 库支持 Python 2 (版本 2.7.x) 和Python 3 (版本 3.3 以后)。下面介绍一些好用的命令行使用程序—— ku 和 tx。
实用密钥程序（KU）
命令行实用程序 KU ( key utility 缩写)对于处理密钥而言，就如同瑞士军刀一样灵活有用。它支持 BIP32 密钥、WIF 和地址（比特币以及竞争币均可）。下面是一些例子。
使用默认的 GPG 熵池和系统随机数设备（ /dev/random ）来创建BIP32 密钥，如下：

使用口令创建一个 BIP 32 密钥：
本例中的口令很容易猜到。

实用交易程序（TX）
命令行实用程序 tx 可将交易以一种易读的方式呈现，还可以从 区块链 的交易缓存或者网络服务（目前支持 blockchain.info, blockr.io, and biteasy.com ）中获取原始交易，合并交易，添加或删除输入或输出，以及签署交易。
下面是一些例子。
看看有名的“披萨”交易[PIZZA]：

区块链库起初由Richard Kiss 撰写和维护 ，基于 Python 脚本的处理交易密钥，不仅支持比特币交易，也支持其他非标准脚本语言的交易类型。
区块链 库支持 Python 2 (版本 2.7.x) 和Python 3 (版本 3.3 以后)。下面介绍一些好用的命令行使用程序—— ku 和 tx。
实用密钥程序（KU）
命令行实用程序 KU ( key utility 缩写)对于处理密钥而言，就如同瑞士军刀一样灵活有用。它支持 BIP32 密钥、WIF 和地址（比特币以及竞争币均可）。下面是一些例子。
使用默认的 GPG 熵池和系统随机数设备（ /dev/random ）来创建BIP32 密钥，如下：

实用交易程序（TX）
命令行实用程序 tx 可将交易以一种易读的方式呈现，还可以从 区块链 的交易缓存或者网络服务（目前支持 blockchain.info, blockr.io, and biteasy.com ）中获取原始交易，合并交易，添加或删除输入或输出，以及签署交易。
下面是一些例子。
看看有名的“披萨”交易[PIZZA]：
$ tx 49d2adb6e476fa46d8357babf78b1b501fd39e177ac7833124b3f67b17c40c2awarning: consider setting environment variable 区块链_CACHE_DIR=~/.区块链_cacheto cache transactions fetched via web serviceswarning: no service providers found for get_tx; consider setting environmentvariable

糟糕！我们没有设置好网络服务。让我们现在设置：
$ 区块链_CACHE_DIR=~/.区块链_cache$ 区块链_SERVICE_PROVIDERS=BLOCKR_IO:BLOCKCHAIN_INFO:BITEASY:BLOCKEXPLORER$ export 区块链_CACHE_DIR 区块链_SERVICE_PROVIDERS
这不是自动完成的，所以这种命令行工具不会泄漏你在第三方网站交易的隐私信息。如果你想忽略这个提醒，就可以把这些命令行加入到profile文件。
我们再试一次：
