Abstract

The invention relates to the technical field of block chains, and discloses an electronic contract storage method and a device based on a block chain, and electronic equipment, and the method comprises the steps: obtaining an electronic contract original uploaded to a block chain network, and enabling the electronic contract original to be an electronic file obtained through the synthesis of an electronic contract and the electronic signature data of a signer; preprocessing the electronic contract original to obtain electronic contract original data; performing encryption processing on the electronic contract original data by using a preset encryption algorithm to generate a data fingerprint; broadcasting a contract number and a data fingerprint corresponding to the electronic contract original in the blockchain network to perform information verification; and if the information verification succeeds, adding the contract number and the data fingerprint to the blockchain maintained by each node in the blockchain network, so that the electronic contract original can be prevented from being disclosed, the confidentiality of the electronic contract original can be improved, the electronic contract original data corresponding to the data fingerprint can be prevented from being tampered, and the real reliability of the data fingerprint can be ensured.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based electronic contract storage method and device, and electronic equipment. Background technique [0002] An electronic contract is an electronic agreement signed in electronic form through an electronic information network, which is used to clarify the rights and obligations between two or more parties. With the development of electronic technology, electronic contract occupies a place in e-commerce activities because of its characteristics of convenient transmission and cost saving. In order to better use electronic contracts to protect the legitimate rights and interests of consumers and operators, proper and safe preservation of electronic contracts is an important part of maintaining personal and corporate information security. [0003] The current method for storing electronic contracts is mainly to synthesize the electronic contract and the electroni...
