Design of Distributed Academic-record System Based on Blockchain

Abstract

As a distributed system, blockchain is currently an attractive choice for the back-end of public services because of its benefits. Decentralized and carries a consensus mechanism making data stored into irreversible ledger is an advantage of the blockchain. This study discusses the architecture design of academic recording systems in Indonesia, which is currently centralized to be decentralized in permitted networks. Participants involved in the network system, namely institutions as academic staff, teachers, students, and external parties, which each participant has the authority and arrangement with smart-contracts. Evaluation results show less time on the proposed system to complete business processes than the currently system. The task of validation activities can be eliminated and perform smart-contract functions inside to become a "trust-less operation", in which academic data are ensured to be protected from abused or damage due to human error. The data that has been included in the ledger consists of personal performance from the history of academic activities required by students that can be traced by interested parties such as organizations wishing to recruit employees, as well as educational institutions that require the achievement of specific information needed by prospective applicants.
