In a blockchain network, each user has a unique account for performing operations such as fund transfers, transaction records, and balance management. These accounts are authenticated and authorized through encryption algorithms and private keys, ensuring the security and integrity of the data. The emergence of blockchain accounts makes decentralized peer-to-peer transactions possible, thereby reducing the intermediary costs of centralized credit institutions and improving transaction efficiency."}]}],"pr":"4293ce5a08eb442e8a798da0648d21722bf9a48bc301953282cbacbcd2114ee2"}
