The blockchain-based learner competition platform system

摘要

A blockchain-based learner contest platform system is provided. In the blockchain-based learner contest platform system, some or all of the first to nth nodes (n is a natural number greater than or equal to 2) corresponding to the learner node or the reviewer node, and the first to nth nodes participate, records in a blockchain-based distributed ledger and manages the distributed ledger to be shared among the first to n-th nodes. A user terminal device that can be used, a verification server that performs a qualification verification procedure operation of the subject of the user terminal device, and the learner node registered in the learner node by analyzing the evaluation result evaluated through the user terminal device and a big data analysis module that determines the talent, aptitude and level of the user using artificial intelligence technology, and outputs a result for the learner's career selection, wherein the user terminal device and the management server each receive DID information Registering in the block chain, the management server receives an electronic verification certificate that can verify the identity, qualification, history and career of the user of the user terminal device from the verification server and delivers it to the user terminal device, but the electronic verification is the management It includes DID information of the server and DID information of the user terminal device, and the user terminal device performs a digital signature procedure on the electronic verification certificate.
