Embodiment Construction

[0026] The blockchain-based real estate certificate and transaction method includes three users: government agencies, developers, and home buyers. The system has different permission designs for different users. Government agencies have the right to supervise and review, developers have the right to develop real estate and sell commercial housing, and house buyers have the right to buy and sell real estate. The smart contracts deployed on the blockchain realize the business logic between various users and record the behavior and operations of each user on the blockchain for permanent storage.

[0027] A blockchain-based real estate deposit certificate and transaction method, including the following functional modules:

[0028] (1) Review the access module. The access right is owned by the government department. There are two types of access objects. One is the developer. The developer can only pass the Quality Supervision Bureau, Housing Management Bureau, Land Bureau, Constru...

Abstract

The invention discloses a real estate storage and transaction method based on a block chain. The system comprises the following function modules: an audit admission module, a real estate development module, a commercial house chain entering module, a commercial house pre-selling module, a second-hand room selling module and a data storage module, according to the invention, the problem of unsmoothinformation circulation among mechanisms is solved; house property development efficiency is low, certificates are counterfeited, the house property data traceability is poor; a series of problems ofprofit-in-the-middle quotient difference, real estate dispute and the like are solved; the invention discloses a real estate transaction method. Compared with the prior art, the transaction process is simplified, the participation of the third-party intermediary is needed in the traditional real estate transaction process, the real estate certificate storage and transaction method based on the block chain can realize the direct transaction of the seller and the buyer without the third-party intermediary, the transaction cost is reduced, the transaction efficiency is improved, and the high efficiency of real estate development, auditing and transaction is realized.

Description

technical field [0001] The invention relates to the technical field of block chains, in particular to a block chain-based real estate certificate deposit and transaction method. Background technique [0002] Blockchain technology is a distributed and decentralized Internet technology that can safely store transaction information and other operational information, and once this information is written into a block, it cannot be tampered with. It was initially used as the underlying technology of Bitcoin appeared. In fact, strictly speaking, blockchain technology is not a new technology but a new architectural model. Blockchain is an organic combination of distributed ledger, asymmetric encryption technology, consensus mechanism, smart contract and point-to-point transmission. Blockchain includes public chain, alliance chain and private chain. Transactions on the alliance chain are completed by the consensus of service nodes on the alliance blockchain. After the consensus is...
