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

Embodiment Construction

[0033] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative efforts belong to the scope of protection of this application.

[0034] Before explaining the embodiments of the present invention in detail, some terms involved in the embodiments of the present invention will be explained first.

[0035] Blockchain: Blockchain technology was born out of Bitcoin technology and is the underlying technology of Bitcoin. It is a decentralized distributed ledger database. The blockchain itself is a series of data blocks (blocks) associated with each other using cryptographic algorithms, and each data block contains information f...

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 that a first node in a block chain receives a timestamp transaction request, and the timestamp transaction request carries block data with a trusted timestamp; when the first node is a target node capable of generating a block, the block is generated, and the block comprises block data with a credible timestamp; a verification request of the block is broadcast to a second node in the block chain, the second node being a node other than the first node in the block chain; a verification result returned by the second node based on the verification request is received; and the block is added to the block chain based on a verification result returned by the second node. According to the embodiment of the invention, the timestamp transaction request is received, and the block data with the credible timestamp is added to the block chain according to the timestamp transaction request, so that the credible timestamp is added to the block data of the block chain, and the performance of the block chain isimproved.

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...
