Description
Technical field
The invention belongs to but be not limited to shared economy and block chain network technical field, and in particular to one kind is based on block chain
The rent method and system of network technology.
Background technique
Shared economy, generally refers to obtain definite remuneration as the main purpose, based on stranger and there are the article rights to use
The new economic model of one kind temporarily shifted, essence are to integrate unused article under line, labour, education and medical care resource.Altogether
Enjoying economy makes people's justice enjoy social resources, respectively pays and is benefited in different ways, obtains economic bonus jointly.With
The development of Internet technology, shared economy are more and more realized by internet as medium.
Block chain technology is a kind of decentralization, distributed, transparent, not modifiable, encryption data storage
Technology is a new technical combinations, it includes key technology, have P2P dynamic group net, the shared account book based on cryptography,
Common recognition mechanism (Byzantium's general's problem, i.e., the consistency problem under a kind of distributed scene), intelligent contract (Smart
Contract) etc..This technical combinations does not overturn existing business, and is the introduction of new thought, goes to improve and be transformed existing
Business model, to provide better, Pu Hui service for masses.Intelligent contract includes the chest being worth just as encryption, only
Have and be just opened when specified conditions are satisfied, it encapsulates some logics, rule, processing step or the agreement of both sides.Intelligence
Energy contract reduces the interference of human factor in network data storage.
Patent of invention " a kind of method, apparatus and system of application block chain network ", publication number WO2018/018992 are public
The method, apparatus and system of a kind of application block chain network are opened, wherein lessor (company or family) is by installing small-sized area
Block chain network server, deployment block chain network client, all block chain network node communication synchronization data with public network, with
Corresponding operating is carried out to internet of things equipment.The house for rent scheme passes through intelligence using block chain network record lease Transaction Information
Contract administration lease transaction.But the invention to house for rent side and does not ask the credit of rent side to assess, i.e., house for rent side can not know
That asks rent side charters history, needs to undertake and subject matter is rented the irresponsible risk for asking rent side, equally rent side is asked to be also required to
It undertakes to rent and the risk for the subject matter that expectation ensures cannot be provided.
Summary of the invention

Breath, while chartering record (credit record) for B is obtained, A charters record and demand information according to B's, it is determined whether by house
Lease to B；B obtains the house information of A publication also by lease block chain network, while obtaining taxi record (the credit note of A
Record), B is according to the taxi record and house information of A, it is determined whether leases the idle house of A；If A and B approve the letter of other side
With record, and A thinks that can would sit idle for Home-renting also thinks that the idle house of A is met the requirements to B, B, then A and B is leased
Transaction；Lease transaction between A and B includes that A provides the unlocking cipher for the house that leaves unused to B, or provides the key of idle house to B
Spoon, to shift the right to use of idle house to B, B then to A payment or rent, is carried out the state of idle house after obtaining the right to use
Evaluation is chartered, and evaluation broadcast extremely lease block chain network will be chartered, after the rental period of idle house, A modification is idle firmly
The unlocking cipher or B in room then give back key to A, so that A withdraws the right to use of idle house, use the case where leaving unused house to B
It carries out hiring out evaluation and evaluation broadcast will be hired out to lease block chain network；The taxi evaluation made with A and chartering of making of B are commented
Valence is the Transaction Information of this lease transaction, and the common recognition mechanism by leasing block chain is remembered Transaction Information as the credit of A and B
Record is respectively written into current block and chain enters to lease block chain.
