Description
Technical field
The invention belongs to public service administrative skill fields, and in particular to a kind of shared lease counterparty based on block chain
Method.
Background technique
The leasing market of China is mainly in the lease for concentrating on house, automobile and large machines building materials.According to statistics, current complete
Population is leased up to 1.9 hundred million people by state, is mainly made of floating population and graduates.According to data, end to 2015
Our floating population reaches 2.47 hundred million people.On the other hand, China leasing market total scale has reached scale up to 1.3 trillion
Member, a tier 2 cities accounting are total up to 5 one-tenth.Think the main battle ground of Science in Future in China leasing market just in one, tier 2 cities, therefore
One, tier 2 cities partition computing market scale is significant.
Maximum is exactly market of renting a house, and it mainly includes three aspects that Chinese housing system, which is constituted: one is transaction city
, the second is leasing market, the third is housing support market.Trade market is the leading role of real-estate market, housing support at present
System Speed-up Establishment and formation scale in recent years, and leasing market is still within autonomous state.Especially lease demand
Housing can only be obtained by second-hand house market, and new rent is substantially absent and rents market, be rented market so as to cause firmly rent
There are a large amount of supply and demand mismatch, the problems such as irregular marketing and moral hazard
In this part thing of renting a house, traditional intermediary, shops is both past tense, and carries out formula now.Because landlord is issued by shops
Article rental information, if being comparatively the selection most saved worry --- house rental information is hung up net by oneself, then will
It is connected to " consulting " phone of many intermediaries, unbearably it is disturbed.Many intermediaries do not stint for passenger flow and issue low price dummy message, catch
Fish is more, but conversion ratio as one can imagine.Many lessees's " Tan Zhongjie discoloration ", that has kept away it is too late.Lessee's experience is poor, passes through simultaneously
Discipline people is bullied, and intermediary company does not make money, this is the extremely low caused lopsided market of an efficiency.
Automobile rent industry is referred to as " rising industry ", it has many advantages, such as arbitrarily replace without year checking maintenance, vehicle,
By controlling cost gradually by domestic enterprises and institutions and personal favor to hire a car instead of buying car.China's automobile leasing row
The current enterprise's number of industry has reached thousands of families, but most scope of the enterprise very littles, and 80% enterprise operation automobile is less than 50,70%
The formal employee of enterprise is less than 5, and 85% enterprise's automobile leasing website number is lower than 2, and small and scattered feature is presented in market.
From the point of view of industry integration degree, the market share shared by preceding 10 enterprises only 11%, first 5 only account for 8%, although in the industry
Automobile leasing enterprise with considerable scale, several families is formed, but overall market share is still lower compared to mature market, scale is leading
Automobile rental corporation also not yet forms leasehold network throughout the country so far, is extremely difficult to the effect of scale economy.
The typical practice that internet promotes industry efficiency is intermediateization.Rent a house, hire a car it is different from pass-along deal, relatively not
So heavy decision, the sensitive lessee of agency expense are more likely to find personal straight tenantry source.Then also there is C2C in leasing market
The mode of intermediary is gone, that is, allows owner and lessee's direct dealing.Problem is that the C-terminal source of goods too disperses and information is opaque, compares
For, there is absolute predominance in intermediary on obtaining the source of goods.At least currently come, C2C can take up sub-fraction market, but short-term
It inside feels like doing and is difficult greatly.
Intermediary is the main channel of traditional lease and internet lease, and no matter traditional industries or internet industry,
It still needs to endorse by company between owner and lessee, for right not in both parties hand, this just has risk, can also damage
The interests of evil both sides.Block chain technology is a better solution, block chain be capable of providing one it is reliable, quick and it is low at
This mode goes to reach the transaction between lessee and owner, and block chain can both accomplish the same trust endorsement of company, without
Concluded the transaction by intermediary.
The present invention using it is distributed using block chain, the characteristics such as can not distort, can be traced and propose one kind and do not having effectively
The method leased safely in the case where having third-party institution's endorsement.
Block chain is a kind of a kind of chain type number for being sequentially in time combined into data block in such a way that sequence is connected
According to structure, and the distributed account book that can not be distorted He can not forge guaranteed in a manner of cryptography.Broadly, block chain skill
Art is to verify to know together algorithm with storing data, using distributed node to generate and update number using block linked data structure
According to, the safety that guarantees in the way of cryptography data transmission and access, utilize and closed by the intelligence that automatized script code forms
About program the completely new distributed basis framework and calculation paradigm of one kind with operation data.
Block chain format is initially used for bit coin, as solving the problems, such as database security and do not need the administrator trusted
Solution.First piece of block chain is implemented in generalities in 2008, and in next year as digital cash bit coin by middle acute hearing
Core component, by using peer-to-peer network and distributed timestamp server, block chain database is automatically managed.Than
The invention of special coin block chain makes it first and solves the digital cash that dual branch goes wrong, and the design of bit coin is always other
The inspiration of block chain application.
Nowadays block chain technology develops rapidly, and can be divided into shared chain, alliance's chain, privately owned chain, this method can be at these three
It is realized in any one in chain, and the deployment success on the hyperledger of IBM and ether mill.
Summary of the invention
