4.3 Zero-knowledge proof protects user privacy
By using the principles of cryptographic techniques (asymmetric elliptic algorithms, etc.), it by constructing a mathematical model. So that the user does not need to disclose the specific content of the information to prove their authenticity to the verifier. This technical principle provides a high level of protection for user privacy and ensures that sensitive information is not disclosed and is widely used in the BOBchain ecosystem.
