摘要
为适应学习型社会对学习者终身教育记录跟踪的深层次、多元化需求,文章基于区块链技术,设计了一种去中心化的终身教育记录跟踪方案--Educhain区块链平台方案。文章指出,Educhain方案将开源公有区块链平台"以太坊"作为底层平台,采用基于同态加密的多方安全计算、智能合约、共识算法与激励机制。Educhain方案充分结合区块链的安全性和去中心化等特征,与教育实体机构形成了虚拟与现实融合的孪生教育空间,不仅有助于跟踪学习者在各个受教育阶段的学习记录,促进学习数据在不同教育机构之间的分发、共享、分析与应用,而且有助于实现数据驱动的教育智能,为学习者提供更精准的个性化学习支持与服务。
In order to adapt to the underlying and diversified needs of the learning-oriented society for the tracking of learners’ lifelong education records, this paper designed a decentralized lifelong education records tracking solution, namely the Educhain blockchain platform solution, based on the blockchain technology. It was pointed out that the Educhain solution took the open-source public blockchain platform "Ethereum" as the underlying platform and adopted multi-party secure computing based on homomorphic encryption, smart contract, consensus algorithm and incentive mechanism. The Educhain solution fully combined the security and decentralization features of blockchain, and formed a twin education space integrating virtual and reality with educational entities, which was not only contributed to tracking learners’ learning records at various stages of education, promoting the distribution, sharing, analysis and application of learning data among different educational institutions, but also helped to realize the data-driven educational intelligence, and provide more accurate personalized learning support and services for learners.
