Embodiment Construction

[0100] In order to make the objectives, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the specific embodiments of the present invention and the corresponding drawings. Obviously, the described embodiments are only some, but not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0101] definition:

[0102] Zero-knowledge proof: It means that the prover can make the verifier believe that a certain statement is correct without revealing any useful information. In a typical zero-knowledge proof process, the prover claims that some public parameters conform to a certain assertion, and based on these public parameters and some private parameters, ...

Abstract

The present invention provides a voting method, device, system and medium based on blockchain and zero-knowledge proof. The method includes: setting a voting initiator I, a verification party A, and W voting parties P in the blockchain i , the voting initiator I sets voting rules and voting options; each P in the W voting parties i Voting, using the first zero-knowledge proof ZKP1 to each of the voting parties P i Proof of results for each voting option; use a second zero-knowledge proof ZKP2 for each of the voting parties P i The results of all voting options are proved; the verifier A calculates the total number of votes for each voting option, and uses the third zero-knowledge proof ZKP3 to prove the total number of votes for each voting option. According to the scheme of the present invention, a secret ballot is realized, and the voting party can prove the validity of the ballot, and the verifier can prove the validity of the voting result, which improves the accuracy and speed of the proof.

Description

technical field [0001] The invention relates to the field of data information processing, in particular to a voting method and device based on block chain and zero-knowledge proof. Background technique [0002] Electronic voting is a common application in the Internet field. The usage scenario is usually that the voting initiator uses the voting function provided by the application server to initiate a vote, sets the corresponding voting rules and voting options, and publishes it to specific or unspecified groups through the application server. The application server then processes and counts the voting results submitted by the voting parties participating in the voting, and presents the total voting results. [0003] However, this electronic voting scheme relies on a centralized server, has extremely high requirements for network security, and the voting results may be manipulated, making it difficult to achieve true secret balloting, which makes the electronic voting schem...
