Specifically, the distributed ledger is jointly completed by multiple nodes distributed in different places, and each node saves the complete ledger data. When a new data block is added to the chain, all nodes synchronize and update their respective ledgers. This decentralized design eliminates the reliance on a single central node, instead distributing the data across multiple nodes throughout the network, thereby reducing the risk of data loss.↵↵Additionally, blockchain employs cryptographic principles to ensure the security and integrity of the data. Each data block contains the hash of the previous block, which serves as a cryptographic signature verifying the authenticity and sequence of the blocks. This prevents unauthorized modifications to the data and maintains the integrity of the overall ledger."}]}],"pr":"f61634fd85a9b87dc1db2b62b15d656a04f75c5ab1dd7f287a5b775699971b13"}
