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

Embodiments of the present application provide a trusted timestamp adding method, device and storage medium, which relate to the technical field of blockchain. Wherein, the method includes: the first node in the blockchain receives a timestamp transaction request, and the timestamp transaction request carries block data with a credible timestamp; when the first node is a target node that can generate a block, generate A block, which includes block data with a credible time stamp; broadcasts a verification request of the block to a second node in the blockchain, wherein the second node is a node other than the first node in the blockchain receiving the verification result returned by the second node based on the verification request; adding the block to the block chain based on the verification result returned by the second node. The embodiment of the present application receives a time stamp transaction request, and adds the block data with a credible time stamp to the blockchain according to the time stamp transaction request, so as to add a credible time stamp to the block data of the blockchain, which improves the Blockchain performance.

Description

[0001] This application requires a divisional application of a patent application with an application date of August 21, 2019, an application number of 201910775729.9, and an invention title of "A Method, Device, and Storage Medium for Adding a Trusted Time Stamp". The contents are incorporated by reference in this application. technical field [0002] The present application relates to the technical field of blockchain, and in particular to a method, device and storage medium for adding a trusted time stamp. Background technique [0003] Blockchain is a decentralized database formed by combining blocks in chains. Specifically, the information generated within a period of time (including the certificate data) is packaged to generate a block, a trusted time stamp is added to the block, and then it is connected with the previous block. In this way, the end to end is connected to form a block. blockchain. Among them, the block header of each block, except the genesis block, i...
