实现了访问钱包数据库wallet.dat

1. 山寨开发关注度：五星

基本上每个客户都会要求修改钱包地址首字母

2. 全局变量

2.1. DBErrors-- 钱包数据库的错误状态

  • DB_LOAD_OK,

  • DB_CORRUPT,

  • DB_NONCRITICAL_ERROR,

  • DB_TOO_NEW,

  • DB_LOAD_FAIL,

  • DB_NEED_REWRITE

3. CWalletDB类

访问钱包数据库,继承CDB

3.1. 成员变量

  • nVersion,版本号

  • vchData,被base58编码的数据.

3.2. 成员函数
