使用签名提交memo上链。

这是个无币区块链的应用，没有UTXO。因此也没有wallet的概念。

客户端可以生成地址，然后使用私钥签名，签名的内容经过服务端检查，可以上链。

生成一个地址 和私钥

  1. python3 client.py -a n

返回的信息类似：

  1. address:Z/qsNWOAAWULpqvtM/OMHmJE+6PG0oPUsOMGk2ySYgrUB5noaZsD6b0NbbPgslr1cdninkqYKcJ+sx74/Mhn2A==
  3. private_key:196f72bf05e307458a0691ca73a2981d859e499ef9fc264183feddde5bd47217

使用签名发消息上链

  1. python3 client.py -a s -f Z/qsNWOAAWULpqvtM/OMHmJE+6PG0oPUsOMGk2ySYgrUB5noaZsD6b0NbbPgslr1cdninkqYKcJ+sx74/Mhn2A== -t Z/qsNWOAAWULpqvtM/OMHmJE+6PG0oPUsOMGk2ySYgrUB5noaZsD6b0NbbPgslr1cdninkqYKcJ+sx74/Mhn2A== -m hello -p 196f72bf05e307458a0691ca73a2981d859e499ef9fc264183feddde5bd47217
