Description
Technical Field
The invention relates to the technical field of block chains, in particular to a system for realizing land circulation traceability and credible transaction by applying a block chain technology.
Background
The land circulation refers to land use right circulation and the meaning of land use right circulation refers to the land use right circulation of farmers possessing the land contract management right to transfer the land use right to other farmers or economic organizations, namely, the contract right is reserved and the use right is transferred, wherein the land circulation particularly relates to a transaction system based on a block chain, the block chain is a term in the field of information technology, and essentially speaking, the block chain is a shared database, and the data or information stored in the shared database has the characteristics of 'unforgeability', 'whole-course trace', 'traceability', transparency ', collective maintenance' and the like.
Along with the more and more current land transaction, directly reach the transaction through the net between connect chartered plane and the lessee, demand when causing the actual operation of land circulation is more and more, and the flow is progressively loaded down with trivial details, when the actual use, still has some shortcomings, for example:
1) when the existing integral land circulation transaction process has security holes in the transaction, the fund security of a lessee cannot be effectively guaranteed, and the security of the integral system cannot be effectively guaranteed.
2) The land circulation transaction system is characterized in that the land circulation transaction system comprises a packet receiver and a lessee, wherein the packet receiver and the lessee can not share information when the land circulation transaction system is operated specifically, namely, the specific transaction intention of the packet receiver and whether the transaction information is read or not can not be received by the lessee in real time, so that the lessee needs to continuously wait for the transaction intention information of the packet receiver, and the overall transaction efficiency is reduced.
3) The existing land circulation transaction system lacks a lessee, mutual information record of a packet receiver and a storage unit for later-stage tracing, so that later-stage transaction is caused to be problematic, even though tracing is not performed, and direct loss of the packet receiver or the lessee is caused.
4) The consumers have a plurality of buying and selling entrances and a large amount of total information, so that the normal consumption of the consumers can be hindered by the junk information and the useless information, the stability of the whole consumption market is influenced, and the market is disordered.
5) Before the package receiving party and the lessee reach the transaction, the package receiving party has very limited knowledge of personal information such as credit points of the lessee, whether the records of losing credit exist and the like, and the lessee also has very little knowledge of specific conditions of the package receiving party, so that the probability of economic loss of the lessee and the package receiving party is increased after the transaction is finished in the later period.
