In traditional authentication processes, users need to provide personal information to third-party institutions, which may lead to data breaches and privacy violations. Blockchain technology uses distributed ledgers, storing identity information on multiple nodes within the blockchain network, ensuring data security  and reliability. Moreover, blockchain technology has the characteristics of being tamper-proof and irreversible, further guaranteeing the safety of user information and privacy.\n\nBased on blockchain, digital identity authentication technology can also achieve anonymous identity verification. Users only need to provide a public key during registration without revealing their true personal information.
