The invention belongs to the technical field of block chains, and relates to a floating population management method and system based on a block chain, which combine a security chip, an intelligent door lock and a block chain technology and are comprehensively applied to related scenes of floating population management. According to the floating population management method and system, privacy protection, data credibility, collaborative credible sharing, light weight, safety and reliability are achieved, wherein the intelligent door lock used in the method is internally provided with the safety chip, has the unique identity ID and cannot be copied or cracked; a built-in secret key of the safety chip is used for digital signature of block chain transaction in combination with the block chain technology; therefore, credibility of original data stored on the block chain is guaranteed, the door lock safety is greatly enhanced and related crimes are reduced; besides, the system is connected with the public securit
