In traditional digital identity verification, centralized storage  is vulnerable to hacker attacks, leading to personal information leaks. Blockchain technology adopts a distributed ledger, storing user information on multiple nodes, thereby enhancing data security and reliability. Additionally, each user has a public key and a private key, with the private key being held solely by the user. During the identity verification process, users only need to use their private keys to sign, and verification personnel use the public key to verify the signature, achieving identity authentication. This process ensures the authenticity of the identity while ensuring the security of user information."}]}],"pr":"7110bcd8a450e72254d24880ba8adbfc80b6a53b18e278ae2bf187c949177b2d"}
