The invention relates to the technical field of block chains, and discloses a consensus verification method and device, a block chain system and a medium. The consensus verification method is applied to a block chain system. According to the method, the biological information of the user is acquired, the biological information is identified according to the block chain system, the authentication file is generated, and the user account is created according to the biological information; extracting a living body recognition operation in the recognition of the block chain system, and encoding the living body recognition operation to obtain a recognition operation sequence; obtaining a first hash value of the block chain system, and verifying the identification operation sequence according to the first hash value to generate a verification file; according to a preset consensus algorithm and a block chain system, consensus verification is carried out on the authentication file and the verification file, and accoun
