As a distributed database based on cryptographic technology, blockchain can securely store and transmit data without revealing personal information. Its main features of decentralization, high security, and controllable transparency make blockchain technology significantly advantageous in protecting personal privacy.↵↵Firstly, blockchain technology adopts various cryptographic technologies such as encryption algorithms, hash algorithms, public key cryptography, and Merkle trees to ensure the security and integrity of the data. Taking Bitcoin as an example, it uses hashed public keys as personal  accounts, hiding users' personal information. In addition, Bitcoin accounts can be designed as one-time use, further enhancing privacy protection."}]}],"pr":"65102b88c890744cf62545fcb887e8f09c5d3fc450f522c233ba681cfa29f720"}
