An electronic data storage method based on a block chain intelligent contract

Abstract

The invention discloses an electronic data storage method based on a block chain intelligent contract, which comprises the steps of raw data uploading, slicing, storing, issuing, data structure defining, anchoring, writing, calling, returning and comparing and verifying. The method utilizes an intelligent contract and a block chain technology, and has features of decentralization, open transparency, unalterable properties, easy traceability and data trustworthiness. By slicing and storing the electronic data in a distributed way, the method solves the problems of serious centralization and long and complex data of an existing electronic data storage method, improves the security of the user data, records the electronic data stored in each customer certificate in the block, traces each electronic data, facilitates the user to supervise the data security, and the like.

Description

technical field [0001] The invention relates to the field of block chain smart contracts, in particular to an electronic data storage method based on block chain smart contracts. Background technique [0002] The current mainstream electronic data storage method is based on centralized nodes. In fact, some electronic evidence is stored in the online server. Its mode is similar to the current "network disk", but the purpose of electronic storage is to prevent infringement incidents. When the occurrence of disputes and disputes over rights and interests arises, evidence is preserved. Compared with the photographic evidence collection and document archiving when the Internet was not popularized in the past, electronic evidence preservation is only adapted to the Internet era, and the innovative evidence preservation mode not only has a wider scope of application, but also is more comprehensive and efficient. [0003] However, the current electronic data storage mainly has the ...

AI Technical Summary

Problems solved by technology

[0004] (1) The electronic degree of the whole process is relatively low, and the demander needs to hand over the data to a professional credential agency, and after the agency verifies, the relevant verification report will be drawn

[0005] (2) During the implementation process, the risk of electronic data storage is very high, and the data needs to be processed by multiple personnel, and the possibility of changes and tampering is very high

[0006] (3) The service process progresses slowly and the efficiency is low. The demand side sends the data to professional institutions, and the verification institution cannot evaluate the data in time and give an evaluation report in time

[0007] (4) The crisis of trust between users and the system, it takes a long time to establish a reliable trust mechanism with users, and there are many similar certificate storage schemes, which cause changes in market prices

[0009] Smart contract is a concept proposed by Nick Szabo in the 1990s. At that time, due to the lack of a credible and secure execution environment, smart contracts were not applied to the actual industry
