Problems solved by technology

[0003] In the existing technology, the filtering of illegal data is carried out through the browser outside the block chain, which relies too much on external devices, resulting in the restriction of the block chain system architecture, and must be connected to the block chain browser to filter the data, so that the block The chain data filtering process is more cumbersome and cumbersome
Or perform data filtering through the filtering rule table set outside the blockchain, send the blockchain data and the corresponding chain identifier to the content security module, and perform data filtering through the filtering rule table in the content security module, which is too dependent on external data sources The filter rule table, the filter table needs to be updated dynamically, when the blockchain multi-node is deployed across regions, the additional overhead of blockchain data synchronization is increased

Abstract

The embodiment of the invention discloses a data processing method and device based on a block chain, electronic equipment and a storage medium. The method comprises the steps of querying a filteringrule from a rule sub-block chain of a block chain network in response to a service transaction processing request obtained from a user node; and filtering the service data in the service transaction processing request based on the filtering rule, and processing the service transaction processing request according to the filtering result. The rule sub-block chain is introduced to store the filtering rule, so that the filtering rule does not depend on an external device, the filtering rule can be synchronized in real time at different block chain nodes, the data filtering efficiency in the blockchain can be improved, and data supervision of the block chain is facilitated.

Description

technical field [0001] The embodiments of the present application relate to the technical field of blockchain, and in particular, to a data processing method, device, electronic device and storage medium based on blockchain. Background technique [0002] Blockchain is a new application mode of computer technology such as distributed data storage, point-to-point transmission, consensus mechanism, and encryption algorithm. , which has the characteristics of non-tamperable information, decentralization, and openness. Due to the non-tamperable feature of the blockchain, if someone uses the blockchain to spread illegal content, it will bring great challenges to the supervision of the blockchain. [0003] In the existing technology, the filtering of illegal data is carried out through the browser outside the block chain, which relies too much on external devices, resulting in the restriction of the block chain system architecture, and must be connected to the block chain browser ...
