Embodiment Construction

[0032] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.

[0033] Such as figure 1 As shown, the specific steps of a blockchain electronic certificate storage method based on deterministic consensus and credible time stamp of the present invention are as follows:

[0034] Step S1: The blockchain system initializes and builds the genesis block, and the seed node calculates the hash value of the genesis block and applies for a trusted time stamp certificate from the National Time Service Center of the Chinese Academy of Sciences;

[0035] Step S2: Apply for a trusted time stamp certificate at intervals Δt or block number Δb;

[0036] Step S3: After obtaining the trusted timestamp certificate, the consensus node constructs a transaction containing the trusted timestamp certificate information, and packs it into a new block;

[0037] Step S4: Repeat steps S2 to S3 to continuously pack transactions containing cr...

Abstract

The invention provides a block chain electronic storage method based on deterministic consensus and trusted timestamp, the invention relates to the field of electronic storage of block chains, By applying for trusted timestamp certification to the National Time Service Center of the Chinese Academy of Sciences at regular intervals / number of blocks, A chunk node in a chunk chain system constructs atransaction using a trusted timestamp returned by a national time service center and broadcasts the transaction, Finally, packaging the transaction nto a new block together with other certificates inthe system, which not only improves the cost performance, but also effectively enhances the accuracy of time data and the reliability of electronic evidence in the block chain.

Description

technical field [0001] The invention relates to a block chain electronic certificate storage method based on deterministic consensus and credible time stamps, and belongs to the technical field of block chain electronic certificate storage. Background technique [0002] Blockchain is a distributed and trusted ledger, which has the characteristics of distributed, decentralized, traceable, and non-tamperable. Its core value is to establish multi-party trust. The unique data structure of "block" and "chain" can faithfully and completely record the authorized behavior signed by the subject. Users can distrust the blockchain system, but every piece of data it issues has its authorized source, which is traceable and verifiable. The implementation of the blockchain should prevent the traditional system from overriding the authorization of the subject to act on its own, and a good blockchain system should allow the subject to clearly understand the possible risks of their authoriza...
