Problems solved by technology

This method of adding credible timestamps requires the blockchain itself to obtain credible timestamps, that is, the consensus nodes of the blockchain need to obtain credible timestamps when generating blocks. Trusted time, intrusion into the blockchain, the code of the consensus node needs to be modified so that the consensus node supports obtaining trusted timestamps, thus reducing the performance of the blockchain

Abstract

The embodiment of the invention provides a trusted timestamp adding method and device and a storage medium, and relates to the technical field of block chains. The method comprises the steps of obtaining block data of a current latest block on a block chain; obtaining credible time, and adding a credible timestamp to the block data according to the credible time to obtain the block data with the credible timestamp; constructing a timestamp transaction request according to the block data with the credible timestamp; and sending the timestamp transaction request to a node in the block chain, soas to enable the node to add the block data with the trusted timestamp to the block chain according to the timestamp transaction request. According to the embodiment of the invention, the trusted timestamp is asynchronously added to the block data of the current latest block of the block chain, so that the performance of the block chain is improved, and the block chain is convenient to manage.

Description

Technical field [0001] This application relates to the field of blockchain technology, in particular to a method, device and storage medium for adding a trusted timestamp. Background technique [0002] Blockchain is a decentralized database formed by combining blocks in a chain. Specifically, the information (including the deposit certificate data) generated within a period of time is packaged to generate a block, a credible timestamp is added to the block, and then it is connected with the previous block. In this way, it is connected end to end to form a block. Block chain. Among them, the block header of each block, in addition to the genesis block, includes the hash value of the previous block, the block body of each block includes at least one transaction, and the transaction includes the generated The information includes, for example, deposit data. Since the blockchain adds a credible time stamp when generating a block, the time when the information stored in the blockch...
