学历、学位造假是目前就业市场的一种乱象,传统的学历学位认证系统则存在数据易被篡改、易丢失等风险.为此,本文结合区块链技术设计了一个可溯源、可监管的学位学历认证管理框架.为了解决传统区块链系统共识时存在认证时间过长、资源消耗过大的问题,提出了一种新型基于信任的低能耗权益证明算法 ToS(trust of stake).以此为契机,使用以太坊框架开发了一款基于ToS底层共识的学位学历认证管理系统,实现了学位信息录入、查询、认证和撤销等主要功能.实验结果表明:该系统能够确保信息的可认证和可溯源管理,具备执行效率高、能耗低、不易受篡改和攻击等优点.
Low-energy Diploma Authentication Management Based on Blockchain
Forgery of academic qualifications and degrees is a chaotic phenomenon in the current job market.The traditional diploma authentication systems have the risks of data being tampered and lost.Therefore,a traceable and regulated diploma certification and management framework was designed based on blockchain technology.To solve the problems of long-time authentication and excessive resource consumption in the traditional blockchain consensus,a novel trust-based low energy proof-of-right algorithm ToS(trust of stake)was proposed.Taking this as an opportunity,a diploma authentication management system based on ToS underlying consensus was developed using the Ethereum framework,which included main functions of information record,query,authentication and revocation.The experimental results showed that the system could ensure the authenticity and traceability of data with the advantages of high efficiency,low energy consumption,and low susceptibility to be tampered and attacked.
