However, in blockchain systems, data security and privacy protection have always been a challenge. To address this issue, blockchain has adopted a  series of technical measures to deal with data privacy and confidentiality issues.↵↵Firstly, blockchain uses encryption algorithms (such as symmetric encryption and asymmetric encryption) to protect data. Through encryption, only users with the correct keys can access and interpret the data in the blockchain, ensuring the security of data during transmission and storage.↵↵Secondly, blockchain has designed complex consensus mechanisms to prevent malicious attacks and tampering. In a blockchain network, nodes must reach a consensus on the validity of a transaction before it can be added to the blockchain. This process involves a series of intricate calculations that make it difficult for attackers to tamper with the blockchain.↵↵By adopting these technical measures, blockchain aims to provide a secure and transparent platform for data storage and transmission"}]}],"pr":"b85f91730fa4105c2ff132a044c380b669b874c4ef240df21527821141be29ac"}
