As a chain of data structures composed of data blocks connected in sequence according to time order, a blockchain records precise timestamps when adding new blocks. This enables the blockchain to ensure the consistency of data sequence and time sequence.↵↵In the upgrade process of a blockchain, developers need to ensure that the new version of the blockchain system is compatible with the old version's data and maintains data consistency and integrity during the  upgrade. Additionally, to ensure the security and stability of the blockchain network, the upgrade process must fully consider factors such as the consensus algorithm and encryption technology of the blockchain network, ensuring that the upgrade does not compromise its security and stability."}]}],"pr":"ba1673e5fbc35e216045f18e4ec623bf9320e6fec12e5ecd6d3272ac237f3b03"}
