In fact, blockchain-based digital identity authentication technologies have been widely applied in various fields. For example, in finance, healthcare, e-commerce, and other industries, blockchain  technology can improve the security and efficiency of digital identity authentication.↵↵Traditional digital identity authentication technologies have some issues, such as centralized storage being vulnerable to hacker attacks and personal information leaks. However, blockchain technology has a decentralized storage method that can ensure the security and reliability of the data. Digital identity authentication technologies based on blockchain can use distributed ledger technology to store user information. Each user will have a public key and a private key, and the private key can only be accessed by the user himself."}]}],"pr":"c7d0a3a5d558bbdeb9c776685bb9cf3af4f3e399358869eada85dfb553e8ba70"}
