  • string Type
  • string Proof
  • uint256 StartDate
  • uint256 EndDate
  • uint256 TokenAmount
  • string Extended => 对应db哪些字段 ?
CREATE TABLE public."Contribution" (
	detail text NOT NULL, => Detail
	proof text NOT NULL, => Proof
	credit float8 NOT NULL, => TokenAmount
	"toIds" _text NULL,
	status public."Status" DEFAULT 'UNREADY'::"Status" NOT NULL,
	"ownerId" text NOT NULL,
	"projectId" text NOT NULL, => ProjectAddress
	"createAt" timestamp(3) DEFAULT CURRENT_TIMESTAMP NOT NULL, => 根据db写入时间控制
	"updatedAt" timestamp(3) NOT NULL, => 根据db写入时间控制
	deleted bool DEFAULT false NOT NULL,
	"uId" text NULL, => AttestationUID
	id text NOT NULL, => ContributionID
	"contributionDate" text NULL, => {"startDate":"","endDate":""}
	"type" _text NULL, => Type
	"endDate" timestamp(3) NULL, => EndDate (和 contributionDate 用哪个？)
	"startDate" timestamp(3) NULL, => StartDate (和 contributionDate 用哪个？)
	"imageList" _text NULL => 好像在Proof里面？ Proof = <p>1</p> <<imageList>> []
);

db表的数据其实是比eas多一点，

frontend -> backend -> eas -> DB (同步)

后端肯定是写eas + db成功率高

  • 写eas失败，直接报错
  • 写eas成功，写DB成功
  • 写eas成功，写DB失败 （同步机制）

Step: (定时任务每天跑一次更新全量遍历) + （定时任务 每10分钟跑一次，只拿最近15分钟的uid 可选）

  1. 在EAS中根据每个Schema ID 查询到所有的AttestationUID (已经有唯一索引)
  2. 对于每条AttestationUID，如果不存在，直接写入
  3. 对于每条AttestationUID，如果存在，进行一次对比，查看是否需要覆盖写，
  • 这里可以SynStatus状态可以多加一个？比如INIT 状态表示已经同步好，后续不需要重复对比，数据量大的时候可以加

status = UNREADY || READY || CLAIM
