As a decentralized distributed encrypted database, blockchain technology combines disciplines such as cryptography, mathematics, and computer science, and has characteristics such as decentralization, trustlessness, and difficulty in tampering. In blockchain technology, privacy information can be roughly divided into two categories: identity privacy and transaction privacy, which are the focus of current research on network privacy security. Blockchain technology ensures individual data autonomy through peer-to-peer network technology, asymmetric encryption, and consensus mechanisms, bringing new possibilities for privacy protection.\n\nZero-knowledge proof technology is a privacy protection solution in blockchain DApps. It can help protect users' privacy by allowing them to prove certain statements about their data without revealing the data itself. This technology enables secure and private transactions while maintaining the integrity of the blockchain network. By utilizing cryptographic techniques, zero-knowledge proofs enable users to verify the correctness of transactions  without exposing any"}]}],"pr":"0f3fe1017cc96189b4194d15af80a3ebd1439799c11e3a84464e387d383c0bee"}
