Abstract

The invention relates to the field of real estates, and discloses a block chain-based house history generation method. The method comprises the following steps of: firstly filling information, carrying out operation by a block chain, generating first block data of a house, verifying validity of the first block data, and storing the first block data in the whole block chain; when the house state changes, for example, data updating or owner alternation is carried out, obtaining data of the last block from the whole block chain, filling modification content or alternation content, carrying out operation by the block chain, generating the current block data, verifying effectiveness of a signature of the current block data and integrity of the modification content or the alternation content, and storing the current block data in the whole block chain. According to the method, uniform house history is formed, and the disclosed information cannot be tampered, so that the correctness and tamper-resistance of the house information are ensured.

Description

technical field [0001] This program relates to the field of real estate, specifically a method for generating housing history records based on blockchain. Background technique [0002] The blockchain is essentially a decentralized distributed database. It does not require a centralized agent, and realizes a point-to-point direct interaction, making a high-efficiency, large-scale, and non-centralized agent-free information interaction method a reality. At the same time, the blockchain uses cryptography to ensure that the existing data cannot be tampered with. Every piece of data recorded on the blockchain remains true and reliable, and at the same time, it is open and transparent and can be viewed by others (but the trader's personal or Institutions can be anonymous), so there is no need to know and trust unfamiliar counterparties, you only need to see that the information and assets of the counterparty on the blockchain are credible, and you can trade with confidence. There...
