Information monitoring method, system and equipment and storage medium

Abstract

The invention discloses an information monitoring method and system, information monitoring equipment and a storage medium. The method comprises the following steps of disclosing trap door public parameters to transaction nodes in a block chain system, wherein the trap door public parameters are generated by calculation based on the pre-stored trap door information; acquiring a tracking key generated by the transaction node according to the trapdoor public parameter and the transaction amount value; and calculating and generating a transaction amount value according to the tracking key and the trap door information. According to the method, monitoring of the transaction amount of the block chain with privacy protection is realized, and overall stability and availability of the block chain system are ensured. In addition, the invention further provides a block chain system, information monitoring equipment and a storage medium, and the beneficial effects are as described above.

Description

technical field [0001] The present invention relates to the field of block chains, in particular to an information monitoring method, system, equipment and storage medium. Background technique [0002] At present, blockchains that can achieve privacy protection are mainly represented by Monero and Zerocoin, which often do not have the function of supervising the substance of transaction data. [0003] In the transaction process based on the block chain, the proof of the legality of the transaction amount often needs to be realized by means of interval proof, that is, the corresponding commitment information is generated according to the transaction amount, and the commitment information can only reflect the specified range of the transaction amount, but The exact transaction amount could not be disclosed. The currently widely used interval proof scheme in many privacy-protected blockchain projects is the Bulletproofs interval proof scheme with shorter proof size and higher ...

Problems solved by technology

[0004] In actual scenarios, the blockchain with privacy protection may be frequently used by malicious users for small transactions or sudden changes in the amount of user accounts due to system vulnerabilities. However, it is impossible to determine the existence of an abnormal state due to the inability to know the transaction amount. , it is difficult to ensure the overall stability of the blockchain system. In addition, it is also difficult to realize the supervision of transaction content, and it is impossible to ensure the overall usability of the blockchain system.
