Problems solved by technology

[0003] Under the previous blockchain technology, the information stored in the blockchain may become the entry point for illegal activities such as data theft, pornography, gambling, and anti-social propaganda, which will bring unpredictable damage to the property and life safety of the country and the people. potential threat
Moreover, once harmful information is successfully written into the blockchain, it will always exist and is difficult to remove, and may even cause great damage to the credibility, use and application value of the entire chain due to harmful information in a block
In particular, some social institutions such as banks, medical care, and education that are eager for blockchain technology use blockchain technology. Once harmful information is embedded in the blockchain, it will cause incalculable losses. Credibility is needed for these Fatal blow to institution's credibility

Abstract

The embodiment of the invention relates to a method and system for controlling harmful information based on a block chain. The method comprises the following steps: generating a main chain block of amain block chain according to a first rule, wherein the main chain block comprises text data; according to a second rule, generating a secondary chain block of a secondary block chain according to themain chain block, wherein the secondary chain block does not include the text data; recording a corresponding relationship between the main chain block and the secondary chain block; and when it is detected that the text data of any main chain block in the main block chain contains harmful information, determining the main chain block containing the harmful information as a harmful block, and replacing the harmful block with a corresponding secondary chain block according to the corresponding relationship. According to the harmful information control method and system based on the block chain, propagation of harmful information in the block chain can be effectively controlled, and the safety of the block chain technology is improved.

Description

technical field [0001] The embodiment of the present application relates to blockchain technology, in particular to a blockchain-based method and system for controlling harmful information. Background technique [0002] Blockchain technology is a decentralized distributed data storage system that can guarantee the authenticity of each piece of information, thereby solving the problem of trust between people and greatly reducing the huge expenses caused by trust problems. [0003] Under the previous blockchain technology, the information stored in the blockchain may become the entry point for illegal activities such as data theft, pornography, gambling, and anti-social propaganda, which will bring unpredictable damage to the property and life safety of the country and the people. potential threat. Moreover, once harmful information is successfully written into the blockchain, it will always exist and is difficult to remove, and may even cause great damage to the credibility,...
