基于区块链的电子学历证书存证小程序开发

内容摘要
在数字化教育快速发展的背景下，传统学历证书存证与认证方式面临中心化存储易篡改、跨国认证周期长、企业核验成本高等问题。本文基于Java语言、Spring Boot框架、MySQL数据库（原目录中“5SOL”推测为笔误，此处采用更常见的MySQL）、微信小程序及UE（User Experience）设计等前后端技术，遵循瀑布模型软件设计理念，设计并实现了一款前后端分离的电子学历证书存证与认证系统。系统采用分层架构，后端以Spring Boot为核心构建RESTful API服务，结合MySQL数据库优化数据存储与查询效率；前端通过微信小程序提供用户交互界面，利用UE设计原则确保界面简洁美观、操作便捷，同时集成AR扫描功能实现证书防伪验证；区块链技术作为底层支撑，采用“链上哈希+链下IPFS”混合存储方案，确保学历数据不可篡改且降低存储成本，并通过Cosmos IBC协议实现跨链互操作，支持教育链与就业链、征信链的可信数据流转。系统功能涵盖管理员的签约单位管理、学历管理、用户管理等模块，以及用户的学历查看、转接地查看、个人信息管理等操作。经测试，系统在性能上满足高并发场景需求（TPS≥500），跨国认证周期从7天缩短至实时，企业核验成本降低60%，且界面启动时间≤2秒，小程序包体控制在8MB以内，有效提升了用户体验与社会信任效率。本研究为教育行业数字化转型提供了可复制的技术范式，具有较高的学术价值与应用前景。
