Decentralization means that there is no central node, and data is stored on multiple nodes to ensure that no single entity can control the data. Cryptographic technology includes end-to-end encryption and public key infrastructure to protect users' sensitive information. Hash functions maintain data integrity and prevent data tampering. Smart  contracts enable automated execution of agreements, enhancing transaction transparency. Combining these technologies, blockchain can ensure data privacy while achieving secure and reliable data storage and transmission."}]}],"pr":"5d93a90caaa72a374e1525bc18ca7f8c6b9d514d3e8a6ee3d46b13247139dfc8"}
