Consensus specific to this protocol
本协议用于在链上注册和管理密码应用（CAPP)。
密码应用（CAPP）：是以非对称密码为身份或账户系统的应用。
AID（Application Identity）: 密码应用注册时的交易id为该应用唯一的应用id，即AID。
注册者可以为应用自由命名，可以用"[stdName]"+"@"+"[cid]"指代一项服务，如“sign.cash@freer_ew8H”，便于识别，也消除商标抢注问题。
注册者应保证自己注册的不同CAPP使用不同的stdName。
流程
注册CAPP：在链上注册CAPP，参见注册CAPP
更新CAPP：在链上更新已注册的CAPP信息，参见更新CAPP
注销CAPP：在链上注销CAPP，宣布注销该CAPP，参见注销CAPP
评价CAPP：在链上对该CAPP进行评价，参见评价CAPP，评分基于币天销毁加权平均。
