摘要
针对目前中国福利彩票系统存在的数据安全程度有限、公开透明力度不足问题,结合实际情况,采用哈希函数和联盟链技术,对传统彩票系统中数据传输记录、开奖号码产生方面进行了改进,设计了一种具有可实践性的彩票系统。该系统具有的优点:分布式存储保障数据安全;节点权限的层次化降低了联盟链中心化程度,维护购买者隐私;全体购买者均可参与数据监督,对开奖号码随机性进行验证。
To solve the problems of the limited data security and fairness in the current China welfare lottery system,combining with the actual situation,we use the hash function and consortium blockchain technology to improve the data transmission records and the generation of lottery numbers.The advantages of the system include distributed storage guarantees data security,and the hierarchical level of node authority reduces the degree of centralization and maintains the privacy of purchasers,at the same time,all purchasers can participate in data supervision and verify the randomness of lottery numbers.
