摘要
为促进区块链技术在教育领域的应用实践,针对学位证书存证的教育业务场景,研究基于区块链的学位证书存证相关应用系统设计。鉴于现有的系统设计大都基于挖矿机制实现,交易处理效率较低,提出基于超级账本的学位证书存证系统设计。将可信学位证书信息存储进区块链中,解决学位证书存储存在的单点故障和潜在篡改问题;利用Kafka作为交易的消息队列,实现交易处理的高吞吐量,该系统设计具有可行性和正确性。实验测试结果表明,相比其它基于区块链的系统设计,该系统具有更高的交易处理速度。
To promote the application of blockchain technology in the field of education,the relevant system designs of degree certificate storage based on blockchain were studied in view of the educational business scenario of degree certificate.Since most of the existing system designs were based on mining mechanism,the transaction processing efficiency was relatively low.A storage and verification system design of degree certificate was proposed which combined with the characteristics of hyper ledger fabric.The system is feasible and correct and it can effectively avoid the problem of tampering and the single point of failure.Kafka was used as the message queue for transactions to achieve high throughput in transaction processing.Experimental results show that the system design has higher transaction processing speed than other blockchain-based system designs.
