substrate-poe's Introduction

基于substrate实现的链上存证功能

1.创建存证

  • 初始链状态中的存储对应的存证为none

avatar

  • 创建存证，再次查看，存证上链

avatar

  • 创建存证成功测试用例 fn create_claim_works()
  • 创建存证失败测试用例-存证已存在 fn create_claim_failed_when_claim_already_exist()
  • 创建存证失败测试用例-存证长度超出限制 fn create_claim_failed_when_length_exceeded()

2.撤销存证

  • 执行poe模块的revoke撤销函数，撤销存证

    avatar

  • 再次查看链上存储，发现为none，存证撤销成功

    avatar

  • 撤销存证成功用例 fn revoke_claim_works()

  • 撤销存证失败用例-存证不存在 fn revoke_claim_failed_when_claim_not_exist()

3.转移存证

  • 执行poe的transfer函数，转移存证

    avatar

    avatar

  • 检查存证发现alice的存证已被转移到bob账户

    avatar

  • 转移存在成功测试用例 fn transfer_claim_works()

  • 转移存证失败测试用例-存证不存在 fn transfer_claim_failed_when_claim_not_exist()
