摘要：

针对学分银行模式下所存在的学习记录不透明、学分易篡改、学习成果认证和转换效率低等问题,提出一种区块链学习成果管控模型。设计模型结构并介绍相关原理,给出改进的实用拜占庭容错共识机制,以实现高效、低耗和可扩展的学习成果管控方式。通过建立学习成果认证和转换标准的智能合约,保证模型在自动化与透明环境下执行。实验结果表明,该模型能够为学分银行模式下学习成果的管理提供新的思路和技术支持。

Abstract:

Aiming at the problems of learning record opaque,easy to credit tampering and low efficiency of learning results certification and conversion faced by credit bank mode,a management and control model of blockchain learning achievementd is proposed.It presented the structure of the model,introduces the related implementation principles.And proposes an improved Practical Byzantine Fault Tolerance(PBFT) consensus mechanism to achieve efficient,low cost and scalable learning results management and control mode,and designed the learning achievement certification standard and the conversion standard smart contract to ensure the automation and transparent execution of the model.Experimental results show that the model can provide new ideas and technical support for the management of learning outcomes under the credit bank mode.

Key words: blockchain, credit bank, consensus mechanism, smart contract, cryptography
