ADA艾达币--交易解析
Hello , 我是09
此篇内容为我2018~2020年在【库神】工作时，对部分重要知识做的学习总结
随着比特币冲破10万美金，行业又再次兴起，希望相关从业者可以学习到你需要的内容
介绍
模型
和比特币一样属于UTXO系列

地址生成
Address(cbor)：
[
[ # Address (as CBOR data item)
h'C61F822357B7F4A48CB9...A7C602C4A7856A6', # Root
{ # Attributes
0: h'8200581CFC310...F678BD553206AC4', # StakeDistribution
1: h'49EB93EC6B3A6205311D' # PkDerivationPath
},
0 # AddrType
],
3948132476 # Checksum
]where:
Root - address root,
Attributes - map with address attributes (currently: stake distribution and derivation path),
AddrType - type of an address,
Checksum - CRC32 checksum of an address.
