Requirement Analysis and Technology Framework of Blockchain+Education

Ideas to strengthen the foundation research and frontier arrangement of new technologies including blockchain have been proposed in the 13th five-year national informatization plan. As a decentralized internet framework， blockchain technology has been applied to finance， notarization and digital asset management and some subversive schemes about it appear. In this article six characteristics of blockchain were summarized as decentralization， true data， self-trust， programmability， public maintenance and quasi-anonymity. To achieve student-centered education， its requirements for blockchain technology are analyzed in the aspects of education resource construction， teaching process evaluation and education input-output. In this paper， the framework of blockchain+education based on big data and cloud computing is established and a universal education experience blockchain (UEEB) system is put forward. The UEEB data block is designed from prototype transactions of interactions between education roles and resources. Refer to ethereum architecture its incentive mechanism is constructed from gas and education coin. The transaction states are represented with the teaching force and learning force of roles and the difficulty and adaptability of education resources. The smart contract used for update of the states and education input-output variables is studied. The UEEB system could support the selfcustomization and maintenance of education blockchain resources. Using the UEEB， motivation of faculty and students could be inspired sufficiently. Every person could act as both a teacher and a student or even a school so that one could fully enjoy personalized teaching and shared learning.
