Traditional authentication processes rely on government or third-party institutions, which can be not only cumbersome but also expensive. Blockchain technology introduces a new way of authentication that removes the need for intermediary institutions, allowing users to verify their identities directly through the blockchain.↵↵On the blockchain, each user's identity information is stored in a block, and each block contains the hash value of the previous block, forming a complete  identity information chain. Users only need to possess the corresponding private key to verify their identities through the blockchain, without relying on third-party institutions.↵↵Furthermore,"}]}],"pr":"539d9bcaec7a4078de62592290e423989dcf324173a1e13a0b4d861e3b1ae10e"}
