Improving the training quality of education and training institutions is one of the important reasons for the sustainable development of training institutions. However, traditional education and training institutions lack supervision, and the process system is not standardized, resulting in a lack of authenticity and reliability of information in the training process. Because most of the traditional education and training systems are centralized, it is difficult to share training data between institutions and relevant departments. Therefore, in view of the problems of data tampering and resource sharing in the field of education and training, combined with the node complexity of education and training scenarios, we propose an education and training blockchain platform suitable for multi-node scenarios to ensure the authenticity of the training data and traceability. In this consortium chain, we design specific ledger structures and corresponding smart contracts to meet different business logic requirements. According to different business data types, we optimize the ledger storage method. To improve chaincode utilization and system transaction throughput, we explore different system configuration rules and provide useful insights. Finally, several experiments are performed to evaluate the security and efficiency of the proposed system.
