chia-tx

chia离线签名，主要用于根据输入，返回未签名的交易

进度

• 离线签名 √
• 生成服务 √
• 添加unix_socket
• 离线生成nft

注意事项

这里阐述一些与官方不同的地方，需要仔细权衡，具体影响暂时未知
1. 官方找零机制是根据（walletSK, index) 来派生公钥地址的，index会记录在数据库中，由于当前
我们是无状态的，所以在这里我们找零的地址是恒定的, 是index=0的钱包地址
2. 所以如果input的私钥的index不是0，则无法进行签名，所以创建签名时coins的私钥一定要与签名的sk保持一致

里面有70mojo，可以用来测试

部分信息

• sk ----> pk ----> puzzle_hash <----> xch_address
• xch开头的钱包地址默认是使用wallet-sk的第0个私钥的公钥生成的
• chia的账户模型与UTXO类似，需要输入和输出，叫做coin，他们都是master-sk根据index 派生的wallet的私钥（挖矿所得的coin具有相同的puzzle_hash, index=0)，当新的coin产生时（转账后有剩余）， 会迭代index，找到未使用的index，然后使用此index对应的公钥生成的puzzle_hash，同时会生成一个合成私钥， 此私钥是签名coin的私钥。

http服务

使用aiohttp写了个简单的http服务，主要提供上面三个方法的调用
