Problems solved by technology

[0003] At present, blockchain-based hardware devices have been explored and practiced in the aspect of collecting data credibly, but the research on the performance of collecting large-capacity data and performing credible verification is still in a blank stage.
However, in actual scenarios, there are often large-capacity data storage requirements, but if a single server device is used to store large-capacity data on the chain, there are problems of low transmission efficiency and the credibility of the data on the chain cannot be guaranteed.

Embodiment Construction

[0051] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, and are not intended to limit the present application.

[0052] In one embodiment, such as figure 1 As shown, a data storage method is provided. In this embodiment, the following steps are included:

[0053] Step S101, storing the initial hash value of the data to be deposited in the blockchain.

[0054]For example, after the initial hash value of the data to be stored is uploaded to the chain, it can be used to verify whether the subsequent uploaded data has been tampered with, whether it is complete, and whether it is credible.

[0055] Step S102 , segmenting the data to be stored to obtain at least two pieces of data, the d...

Abstract

The application relates to a data storage certificate method, device, computer equipment and storage medium. The method includes: storing the initial hash value of the data to be stored in the block chain; fragmenting the data to be stored to obtain at least two pieces of data; Store the piece data in the block chain, and send the first hash value and the second piece data to at least one networking server node, and store them in the block chain through the networking server node; Merging the first data fragment and the second data fragment to obtain target data; verifying whether the target data is credible based on the initial hash value and the target hash value of the target data. The above method uses the hash value to verify whether the data is credible before the data is merged and after the merge, so as to ensure the credibility of the fragmented data and the merged data, prevent data from being tampered with, and make the chaining process more secure.

Description

technical field [0001] The present application relates to the technical field of blockchain, in particular to a data storage method, device, computer equipment and storage medium. Background technique [0002] Utilizing the non-tamperable feature of the data on the blockchain, all kinds of electronic data can be sent to the blockchain for storage on the chain, so as to realize trusted data storage, data traceability and other applications. [0003] At present, blockchain-based hardware devices have been explored and practiced in the aspect of collecting data credibly, but the research on the performance of collecting large-capacity data and performing credible verification is still in a blank stage. However, in actual scenarios, there is often a need for large-capacity data storage. However, if a single server device is used to store large-capacity data on the chain, there are problems of low transmission efficiency and the credibility of the data on the chain cannot be guar...
