基于区块链的学位认证管理系统设计
Design of Degree Confirmation Management System Based on Blockchain

知识经济高速发展的今天，一个高质量的学位证书能大大提高个人的社会竞争力。但是现有的学位管理系统大都以中心化的方式管理数据，存在易篡改、成本高、数据可信度低等问题，学历造假、认证造假现象日益严重，对社会产生了巨大的负面影响。近几年来，区块链技术蓬勃发展，其本质是一种去中心化的分布式网络，允许用户在P2P网络中进行数据通信和交换资源。文章提出基于区块链的学位认证管理系统，包含用户管理、学位管理、学位认证三大功能模块，涵盖了证书认证管理的主要环节，与传统学历学位认证相比真正实现了去中心化的数据管理。将区块链作为底层存储，保证了学位信息的安全性、防篡改性以及可追溯性。系统结合智能合约技术，无需第三方可信中心参与认证管理，在免去大量人工成本的同时，提高了系统内部可信度。
With the rapid development of knowledge economy, a high-quality degree certificate can greatly improve the social competitiveness of individuals. However, most of the existing degree manage-ment systems manage data in a centralized way, which is easy to be tampered with, high cost and low data credibility. The phenomenon of diploma fraud and authentication fraud is becoming more and more serious, which has a huge negative impact on society. In recent years, blockchain technology has boomed. Essentially, it is a decentralized distributed network that allows users to communicate data and exchange resources in a P2P network. This paper proposes a degree certi-fication management system based on blockchain, which includes three functional modules: user management, degree management and degree certification, covering the main links of certificate certification management. Compared with the traditional degree certification, it truly realizes the decentralized data management and takes the blockchain as the underlying storage to ensure the security, tamper-proof and traceability of the degree information. Combined with smart contract technology, the system does not need a third-party trusted center to participate in authentication management, which eliminates a lot of labor costs and improves the internal credibility of the system.
