Abstract

The invention discloses a random number generation method of a VBFT consensus mechanism and a consensus mechanism system, relates to the technical field of VBFT consensus mechanisms, and solves the problem that an existing VBFT consensus mechanism is not safe enough. The method comprises the following steps: secret sharing, non-interactive zero-knowledge proof verification of sub-shares, homomorphic addition of all received secret sub-shares by a participant, decryption of a homomorphic addition result by using a private key of the participant to obtain decryption and decoding. The participant generates and provides a non-interactive zero knowledge proof for verifying its own decryption, and all participants passing verification calculate verifiable random numbers according to the sum of the decoded sub-shares. Secret sharing comprises the steps of polynomial generation, sub share calculation, plaintext coding, public key encryption, secret sub share distribution and the like. On the basis of the invention, multiple parties which are not trusted mutually jointly generate a random number which is calculated by multiple parties and can be verified by any person, the authenticity and the generation process of the random number can be verified by any person, and the invention has the advantages of high efficiency and safety.

Description

technical field [0001] The invention relates to the technical field of VBFT consensus mechanism, in particular to a random number generation method and a consensus mechanism system of the VBFT consensus mechanism. Background technique [0002] Blockchain originated from Bitcoin. In 2008, Satoshi Nakamoto published the article "Bitcoin: A Peer-to-Peer Electronic Cash System", which marked the birth of Bitcoin and blockchain. Blockchain was originally proposed as the core underlying technology of Bitcoin. Through the use of data encryption, time stamps, distributed consensus and other means, decentralized and trustless peer-to-peer transactions were realized. Later, it was gradually expanded to electronic contracts, Internet of Things, Insurance, copyright certificate and other fields. As the underlying technology of the blockchain, the consensus mechanism ensures the correctness and consistency of the distributed ledger data, and is a rule that every blockchain network node ...
