Data processing method and device based on block chain

Abstract

The embodiment of the specification provides a data processing method and device based on a block chain. The block chain comprises service platform node equipment; the data processing method based onthe block chain comprises the following steps : acquiring to-be-audited service data generated by performing service processing on a target user by at least one service processing party through service platform node equipment; performing entity extraction based on the to-be-audited service data, generating shared to-be-audited service data according to the association relationship among the entities in the extraction result; sending a first transaction to the blockchain, the first transaction comprising a first digital abstract of the shared to-be-audited service data to enable the first transaction to be stored in a distributed database of the blockchain after passing the consensus verification of the blockchain. Therefore, the to-be-audited service data are uploaded to the blockchain, and the credibility of the to-be-audited service data is guaranteed in the process of compliance auditing of a service processing party or a service platform according to the to-be-audited service data.

Description

technical field [0001] The embodiment of this description relates to the technical field of blockchain, and in particular to a data processing method based on blockchain. One or more embodiments of this specification also relate to a blockchain-based data processing device, a computing device, and a computer-readable storage medium. Background technique [0002] With the development of Internet technology, all kinds of services have launched online services one after another. Although the online mode is more convenient to serve users, in order to obtain a large sales market, more merchants or shops, individual merchants or Stores will choose to carry out online services alone, or offline services alone, or both online and offline services, so as to attract more users.

Problems solved by technology

[0003] However, with the increase of such phenomena, sales scenarios have become more complicated. When providing services to users, some merchants or stores need to conduct compliance self-examination to determine whether their business scope or business model meets the specified compliance conditions. , with the continuous emergence of new technologies, traditional regulatory compliance methods are difficult to cope with the rapid development of various industries

At present, it mainly relies on the experience of regulatory compliance professionals to analyze and judge the compliance of the business. Not only is the efficiency low, but the requirements for the personnel’s regulatory compliance industry experience are also high, and information acquisition is lagging behind, and the authenticity of information is difficult to verify. Inefficiency, etc., has caused great obstacles to the timeliness and effectiveness of supervision, making the compliance supervision review process inefficient and complicated. Therefore, it is urgent to provide an effective method to solve such problems
