Embodiment Construction

[0031] In order to make the object, technical solution and advantages of the present invention clearer, the present invention 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 invention, not to limit the present invention.

[0032] Such as figure 1 As shown, the overall architecture of the "blockchain-based distributed transaction system", the system is divided into terminal agent nodes, data service nodes, storage-type blockchain, and transaction-type blockchain. The system adopts a double-chain structure, a storage-type blockchain and a transaction-type blockchain. Data service nodes are responsible for transaction processing, establishing secure transmission channels, monitoring blockchain and other functions. The terminal agent node is deployed on the user terminal, responsible for user information entry, generat...

Abstract

The invention discloses a safe storage and retrieval method based on a block chain, belonging to the technical field of computer software, comprising four steps of initializing a public key and a private key, writing a data document, data retrieval and data scoring, which can improve safety and usability by using a plurality of technologies while providing data transaction service. Secure tunnel transmission technology is adopted to ensure the information security in the transmission process. Using block chain technology and distributed system to ensure the stability, reliability, security andavailability of the system, using block chain technology to ensure the information security, disclosure, availability and high performance of the system.

Description

technical field [0001] The invention belongs to the technical field of computer software, and in particular relates to a block chain-based safe storage and retrieval method. Background technique [0002] In the context of "Internet +", the construction of traditional data storage systems faces problems such as high transaction costs, information security and centralized service bottlenecks. The reliability of the centralized system depends on the stability of the central storage and the central database. In a centralized system, service performance bottlenecks or single points of failure will seriously affect the availability of the entire system. The information security construction of the traditional data transaction system relies on the service provider's own construction. There is no open and transparent technical guarantee, and its information security technology has no credibility. Therefore, information security accidents occur frequently, causing users' confidence ...
