In today’s society, the problems of false academic qualifications and tampering of students’ scores are increasingly prominent, and the social recognition of data such as students’ scores is declining day by day. At the same time, the single performance of a student cannot directly reflect the level of students’ ability. In this paper, the bottom technology of blockchain is studied, and the blockchain technology is applied to the outcome-based education (OBE) of engineering education. Based on the graduation requirements, students’ scores can be converted into specific competency values and recorded in the blockchain. Through the decentralization of blockchain, tamper-proof, and other characteristics, a social consensus is formed. At the same time, this paper designs an association code, which is more convenient to learn how to find the records in the output blockchain than the traditional way of tracking the account balance when querying the bitcoin records.
