YOYOW一览
YOYOW全名“You own your own words”，也是基于Graphene底层技术开发的，我近期主要研究Bitshares，行业内的同用一个底层技术的产品也应该看一看。
官网：https://yoyow.org/
钱包：https://wallet.yoyow.org/
浏览器：https://yoyow.bts.ai/
Github位置：https://github.com/yoyow-org
里面只有4个项目，为什么源代码里没啥东西呢？
安装运行
直接去https://github.com/yoyow-org/yoyow-core/releases下载二进制版本吧，有支持ubuntu、mac、windows的三个版本可供下载。
最新版是180313，这都3个月了没有更新，更新频率有点慢啊！
我是想编译源代码运行的，但是没有源代码，二进制运行就相当简单了，直接命令行运行yoyow_node即可。

从日志中看 Adding seed node 了三个节点，是只开放了三个公网的节点吗？
现在yoyow链上数据块并不多，大概几十分钟数据就同步完成了，我们启动节点时带上 --rpc-endpoint=127.0.0.1:8090 参数，再启动 ./yoyow_client 即可连上本地节点了。

这些在bitshares的研究系列中说过不少，而且单独有一遍bitshares研究系列【初识cli_wallet】
专门说明cli_wallet相关操作，这里不再细说了。
看看都有哪些cli接口：

从接口数量上来说相对Bitshares要简单多了！
随便测试的几个命令

}
}
没去全面了解这些字段都是干嘛的
"csaf"是等值yoyo币的积分，150000就是等值1.5yoyo的手续费积分，"core_balance"是yoyo币数量，"uncollected_witness_pay"是未领取的见证人工资，至于资产精度用"get_asset YOYO"取。

嗯，没YOYO，建立失败，等转了YOYO再说，问题是要不要转呢？
