Abstract

The invention discloses a method and system for realizing user operation records based on blockchain data storage service, which belongs to blockchain technology. The technical problem to be solved by the invention is how to use blockchain technology to prevent user operation data from being maliciously tampered with , causing user records to be incorrectly tracked, and how to avoid using the clumsy recording method of traditional user operations, the technical solution adopted is: The method is as follows: Build a certificate deposit service platform: the certificate deposit service platform includes a blockchain platform and a data management module and the certificate deposit service module; the user uploads the data evidence to the block chain in the form of JSON; the certificate deposit service module automatically performs hash calculation on the uploaded file, and calculates the hash value of the file, which is the digital fingerprint The value is written into the deposit smart contract; the deposit transaction is signed by the user's private key to ensure the ownership of the evidence. The invention also discloses a system for realizing user operation records based on blockchain data storage service.

Description

Method and system for realizing user operation record based on blockchain data storage service technical field The present invention relates to block chain technology, specifically a kind of data storage service based on block chain realizes user operation Methods and systems for recording. Background technique [0002] The blockchain technology is a decentralized, non-tamperable shared ledger technology. Decentralized distributed database, the database is jointly maintained by each node on the blockchain, and the consensus algorithm ensures the The above-mentioned nodes are invalid, that is, only modifying the database of a small number of nodes cannot tamper with the data on the blockchain. [0003] Smart contracts, smart contracts on the blockchain are computer programs that are automatically executed under certain conditions. Once deployed on the blockchain, the execution logic cannot be tampered with. [0004] Electronic signature technology, electronic signature ...
