Each block contains the hash value of the previous block, forming a chain-like structure. Once a block is tampered with, it will cause the subsequent blocks to be invalid, making it difficult to tamper with data securely.\n\n3.timestamp：Each block in the blockchain contains a timestamp which records the time when the transaction was completed.
