Abstract

The invention provides a blockchain anonymous voting system and method. A voting system is realized by using a block chain; voting logic is put into an intelligent contract for operation; voting datacan be publicized and transparentized; a centralized node does not exist, even if a single node fault occurs, the overall operation of the system is not influenced;, the voting data in the blockchaincan be tampered by any person, and moreover, by introducing cryptographic technologies such as blind signature and ring signature into the blockchain, details such as identity information and voting intention of voters are hidden on the premise of ensuring the openness and legality of necessary voting data, so that the effect of protecting the privacy of users is achieved.

Description

technical field [0001] The present invention relates to the technical field of blockchain, in particular to a blockchain anonymous voting system and method. Background technique [0002] When a group disagrees, a fair vote is a better way to resolve the issue. However, traditional electronic voting has pain points that cannot be ignored: first, the data of electronic voting is recorded on a centralized system, and there may be situations where someone maliciously tampers with the data for profit, resulting in the voting results not accurately reflecting the real situation of the voting . Secondly, in the centralized electronic voting system, if there is a system failure, communication failure, etc., it will cause the electronic voting system to miss or misrecord the ballots. The voters cannot be informed of the situation due to information asymmetry, and they cannot re-vote or correct it. . Finally, the voting data is stored in the centralized system in clear text, and th...
