它使用python3和piston-lib库，用于与steem网络交互。这里有piston-cli和piston-lib的链接。（这里就不给出链接方式了，大家可自行查阅原文）

命令行工具

用叫做piston的命令行工具，可以让你查阅、发帖、回复、资金账号管理等操作。安装之后，你可以使用piston --help命令查看有哪些可用功能。

安装

用pip安装

pip3 install piston-cli

手工安装

git clone https://github.com/xeroc/piston-cli

cd piston-cli

python3 setup.py install --user

更新

pip install --user --upgrade piston-cli

API连接点

this.piston.rocks

我们使用this.piston.rocks作为API的连接端点，但它只是一个试验性质的。你可以免费使用，用于原型验证，但不要指望它是可靠的，也不要用于性能测试。

运行你自己的节点

假设您知道如何编译官方的STEEM守护进程，您也可以运行类似的节点。（链接请查看原文）

steemd节点

下面是steemd的配置文件config.ini：

rpc-endpoint = 127.0.0.1:5090

seed-node=52.38.66.234:2001
seed-node=52.37.169.52:2001
seed-node=52.26.78.244:2001
seed-node=192.99.4.226:2001
seed-node=46.252.27.1:1337
seed-node=81.89.101.133:2001
seed-node=52.4.250.181:39705
seed-node=85.214.65.220:2001
seed-node=104.199.157.70:2001
seed-node=104.236.82.250:2001
seed-node=104.168.154.160:40696
seed-node=162.213.199.171:34191
seed-node=seed.steemed.net:2001
seed-node=steem.clawmap.com:2001
seed-node=seed.steemwitness.com:2001
seed-node=steem-seed1.abit-more.com:2001

enable-plugin = account_by_key
enable-plugin = account_history
enable-plugin = follow
enable-plugin = market_history
enable-plugin = tags

public-api = database_api login_api
public-api = account_by_key_api
public-api = follow_api
public-api = market_history_api
public-api = tag_api

这将打开本地主机的端口5090，接下来，您可以直接向公众开放这个端口，或者通过一个Web服务器(例如nginx)，添加SSL、负载均衡、流控等能力。

Nginx服务器

this.piston.rocks使用了nginx服务，提供了SSL加密、流控、负载平衡等能力，配置如下所示：

upstream websockets { # load balancing two nodes
server 127.0.0.1:5090;
server 127.0.0.1:5091;
}

server {

}

}

}

如upstream配置块所示，它提供了两个steemd节点，用于负载平衡和容错能力。比如一个节点升级代码时，而另一个可以接管整个流量，反之亦然。
