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 achieving privacy protection. Ethereum has adopted ZKP technology in its Layer2 hierarchical expansion solution. Secure multiparty computation enables multiple parties to securely transmit information without revealing any information in the absence of a  trusted third party. The application of these technologies in the blockchain field helps to protect identity privacy and transaction privacy, thereby enhancing the level of cybersecurity."}]}],"pr":"9756f0b63904fc4935243f5533b2f93b4de06a1aba85174dd4924a48ddf12b8e"}
