Firstly, it adopts a decentralized architecture, eliminating the risk of single-point control and improving data security. Secondly, blockchain technology uses asymmetric encryption algorithms to ensure that only the parties involved in the transaction can decrypt related data, preventing data theft during transmission. Additionally, cryptographic technologies such as hashing algorithms and Merkle trees in blockchain can effectively ensure data consistency and integrity, preventing data tampering. Meanwhile, zero-knowledge proof technology can verify the correctness and authenticity of data without leaking original data, thereby  protecting user privacy. Furthermore, certain digital currencies such as Bitcoin and Z are also utilizing these technologies to enhance user privacy protection."}]}],"pr":"c18334ee4f7b82578bb369f6d629a2a8c66803ec5a3297a7603e2cd1deb409f4"}
