Firstly, blockchain adopts encryption algorithms such as asymmetric encryption and hash algorithm to encrypt and decrypt data, ensuring the security and integrity of data. Secondly, blockchain uses distributed ledger technology, dividing data storage into multiple nodes, increasing the difficulty of data  access. In addition, blockchain has also implemented permission control mechanisms, allowing only users with corresponding permissions to access specific data, thereby protecting data privacy.\n\nAdditionally, the combination of blockchain technology and privacy computing technology can protect privacy during data sharing and computation. For instance, the domestic first"}]}],"pr":"a4d117d1967c4e91c8c419ff4ff386bc56180f77f98f81b848d61c3c7271421d"}
