Specifically, it distributes transaction information across various nodes in the network, which reach consensus on the consistency and security of the transactions through the consensus mechanism, without the need for centralized institutions to manage and validate transactions. In blockchain technology, each node has a copy of the ledger, recording all transaction information. When a new transaction occurs, it will be broadcast to all nodes in the network, which verify the validity of the transaction through the consensus mechanism and add it to their own ledgers. In this way, each node has the same ledger, and no node can tamper with or modify the information."}]}]}
