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 ...
