Zero-knowledge proof technology allows the prover to convince the verifier of the authenticity of the information without providing direct information to the verifier, thereby effectively protecting privacy. Blockchain platforms such as Ethereum apply zero-knowledge proof technology to Layer2 hierarchical expansion solutions to achieve privacy protection for transaction information. Secure multiparty computation technology enables multiple parties to securely transmit information without  revealing any information in the absence of a trusted third party, thereby protecting privacy. In addition, blockchain technology itself has characteristics such as decentralization, trustlessness, and resistance to tampering."}]}],"pr":"5fe5cb7a6c6bbeb00753abfcd29e88ca61772ab57d2fc4abecfbb00643cd9704"}
