Double-chain retrieval and traceability method based on real estate transactions

Abstract

The invention discloses a double-chain retrieval and traceability method based on real estate transactions, and relates to the technical field of real estate transactions. Through the cross-chain data collaboration between the government affairs chain and the tax chain, the cross-department exchange and intercommunication of real estate tax data can be promoted, the risk of the taxation process can be reduced, and the overall improvement can be achieved. The quality and efficiency of real estate tax collection and management. Deeply apply blockchain technology to the whole process of the real estate transaction life cycle, greatly shorten the real estate transaction processing time, and significantly improve the business environment; through different real estate transaction business scenarios, select the pain point business that is closely related to the rights and interests of taxpayers On-chain, supported by the cross-chain technology of blockchain, solves the practical problems of real estate transaction collection and management, and meets the needs of "real-time information connection, process traceability, and data tamper-proof"; combined with advanced information technology, it further promotes real estate transaction collection and management The improvement of quality and efficiency will promote the innovation of real estate transaction collection and management methods, models and concepts.

Description

technical field [0001] The invention belongs to the technical field of real estate transactions, in particular to a double-chain retrieval and traceability method based on real estate transactions. Background technique [0002] Exploring the use of blockchain to realize real estate transaction taxation and registration information sharing will help further promote "one-window acceptance and parallel processing", which is of great significance for reducing the time for real estate registration and optimizing the tax business environment; [0003] For traditional government affairs integration platforms that have not adopted blockchain technology or regional cities that have not aggregated government affairs integration platforms, the tax chain connected to the State Administration of Taxation adopts the API interface method, SDK method or business node method; traditional access The disadvantage of the method is that the real estate transaction can not be completely traced be...

Problems solved by technology

[0003] For traditional government affairs integration platforms that have not adopted blockchain technology or regional cities that have not aggregated government affairs integration platforms, the tax chain connected to the State Administration of Taxation adopts the API interface method, SDK method or business node method; traditional access The disadvantage of the method is that the data under the chain of the real estate transaction cannot be completely traced before it is connected to the tax chain of the State Administration of Taxation, and the credibility of the data source is difficult to guarantee. For this reason, a double-chain search and trace method based on real estate transactions is now provided
