Community data chaining method by means of block chain and equipment thereof

Abstract

The invention discloses a community data chaining method by means of a block chain and equipment thereof. The method comprises the steps that a block chain node receives a community data chaining request sent by a first client; a verification smart contract is triggered, the verification smart contract verifies the identity of the first client, and after the verification is passed, an uplink process of the community data is executed; a query request of the community data of a second client is received; a verification smart contract is triggered, wherein the verification smart contract verifies the identity of the second client; a query uplink request sent by the first client is received, wherein the request comprises community data encrypted by a public key of the second client; and a verification smart contract is triggered, the identity of the first client is verified by the verification smart contract, and after the verification is passed, an uplink process is executed on the community data encrypted by the public key of the second client. The community data can be linked, and is public and credible.

Description

technical field [0001] This application relates to the technical field of block chain, and in particular to a method and device for uploading community data by means of block chain. Background technique [0002] At present, blockchain technology is based on a decentralized peer-to-peer network, using open source software to combine cryptography principles, time series data and consensus mechanisms to ensure the coherence and continuity of each node in the distributed database, so that information can be verified instantly , traceable, but difficult to tamper with and unshielded, thus creating a shared value system of privacy, efficiency and security. [0003] Existing community platforms (such as: Baidu Tieba) all use centralized databases, which store community posts of commodities, community time, mobile phones used by users in the community, etc.; however, the databases of community platforms have data tampered with , The authenticity of the data is not guaranteed, and t...

AI Technical Summary

Problems solved by technology

[0003] Existing community platforms (such as: Baidu Tieba) all use centralized databases, which store community posts of commodities, community time, mobile phones used by users in the community, etc.; however, the databases of community platforms have data tampered with , The authenticity of the data is not guaranteed, and the community operating platform modifies the content of the community post of a product

Especially for some small-scale community platforms, the data security and authenticity of posts cannot be guaranteed: and the community content of goods or services is not authentic, which will mislead users and affect user experience
