These transactions are recorded and verified through blockchain technology to ensure the authenticity, security, and traceability of the transactions. In a blockchain network, the parties involved in a transaction do not need to trust intermediary institutions (such as banks), but rather establish trust through encryption algorithms and consensus mechanisms. The transaction process typically includes several steps: initiating the transaction, broadcasting transaction information, verifying the transaction (if necessary), and confirming the transaction. Once the transaction is confirmed, it is permanently recorded on the blockchain, achieving secure value transfer."}]}],"pr":"13c04d00dedab8c6e0989aeb3c2b95b11bd646d88f2f38cc79071743910c1c06"}
