| description | The invention discloses a timestamp marking method based on a block chain, and the method comprises the steps: carrying out the endorsement of a transaction through each peer node after a batch transaction proposal is received; the transaction information is packaged; the packaged block is discharged, wherein the discharged block comprises the block height, the block hash of the block chain and the block hash of the previous block chain; marking the credible time of the first block generated in the batch transaction as the first credible time, and marking the credible time of the last block generated in the batch transaction as the last credible time; performing Merkel root operation on the block Hash of all blocks generated by the batch transaction to obtain root Hash; marking the trusted time of the root hash as the root hash time; the root hash time and the block height are written to a new transaction. According to the invention, the calling frequency of the timestamp is reduced, the system fault risk cau |
