如何在2-3 multisig / P2SH中计算锁定脚本

Question

在比特币测试网下的比特币核心守护程序v0.16.99.0-7c32b41版本

Ubuntu 14.04.5 LTS x64

我对P2SH的了解

锁定脚本：O(NlogN)

我做了什么

1. 生成3个新地址，转储私钥

RIPEMD160<Hash256<2 PK1 PK2 PK3 3 OP_CHECKMULTISIG>>

1. 生成2-3个multisig地址

fe2c7d8886d6dacaec530916a108ad2dd040fbf72c80ea3ddd6d4f220e7e8b3a指的是RIPEMD160<Hash256<2 PK1 PK2 PK3 3 OP_CHECKMULTISIG>>，它不等于89f4d9cdd2b3a68a1c93d8de4417eda6e4dfdbc9
