The tedious steps of product exchange, enhance the information openness and Item Value transparency of article swap meet.
Fig. 1 is shown in which that the schematic diagram of the exemplary block chain network 100 of the embodiment of the present disclosure may be implemented.Block chain
Network 100 includes multiple block chain nodes 101,102,103,104.Since block chain technology has decentralization, distributed
Characteristic, each block chain node can intercourse information by various communication medias.User can be by (for example, client or answer
With routine interface) access block chain link point 101-104 in several block chain nodes initiate transaction, when transaction reaches a fixed number
After amount or time-out, one or more transaction is packaged into block and is sent to block chain node.Furthermore, it is possible in each block chain
The management operation of intelligent contract is executed at node 101-104, intelligent contract installs and deploys, so that transaction is to pass through
Intelligent contract is called to realize.In addition, the quantity of the block chain node in Fig. 1 is only signal rather than limits, it can be and appoint
Meaning quantity, the block chain network 100 can also include the block chain node of various other types.Preferably, block chain network 100
It is alliance's chain, each node participates in Maintenance Association chain network in alliance's chain, and alliance's chain network is an extensive improvement community,
But also allow under extensive community that there are multiple and different small collectives.Each node of alliance's chain usually has corresponding reality
Body tissue, by that could be added and exit network after authorization, each mechanism forms the relevant alliance of interests, common to safeguard block chain
Health operating.Lower operation cost and maintenance can be used in alliance's chain, and transactions velocity also improves many than publicly-owned chain, multiple
Multicenter is in the weak center of coalition formation, has higher confidence level than privately owned chain, has been very suitable to multiple centralizations
Enterprise's scene that mechanism vies each other, by using alliance's chain technology, each common recognition node is equality, efficiently solves ridge
Disconnected problem.
Fig. 2 shows the processes according to the method 200 of the barter based on block chain of the embodiment of the present disclosure.It can be by
The block chain node of the block chain network 100 of Fig. 1 executes method 200, and method 200 is described below in conjunction with Fig. 1 and Fig. 2.Such as
Shown in flow chart, method 200 the following steps are included:
Step 201: receiving the transaction request associated with article from transaction initiator, wherein the transaction request packet
Include the identification information for identifying the article.For example, (being provided for example, the node can correspond to transactional services in block chain node 101
Side's (for example, medium platform etc.)) at, transaction request (example associated with article is received from transaction initiator (for example, the side of selling)
Such as, article is sold in the side's of selling request), wherein the transaction request includes the identification information for identifying the article.For example, identification information
Article, the place of production, manufacturer, the model of article etc. can be uniquely identified.
Step 202: the identification information based on the article obtains the Item Information of the article from block chain account book.For example,
At block chain node 101, when the information cochain of article, it can be obtained from block chain account book opposite with identification information
The Item Information answered.
Step 203: assessing the article based on Item Information to generate estimated value, and give birth to the broadcast of block chain network
At estimated value.In this step, a transactional services provider can assess article to generate estimated value, and will give birth to
At estimated value broadcast to block chain network, so as to other transactional services providers can obtain its offer assessment valence
Value.For example, can based in Item Information at least part (for example, as described below one of Item Information or
Much information) assess the article to generate estimated value,
Step 204: the reference value of the article is generated based on the estimated value information received, the estimated value information
Multiple estimated values including multiple block chain nodes from the block chain network.For example, can be connect from block chain network
Multiple estimated values of multiple block chain nodes (for example, corresponding to multiple transactional services providers) are received, it can be more based on this
A estimated value generates the reference value of the article.For example, the average value of multiple estimated value can be generated, (or weighting is flat
Mean value) using the reference value as the article.In addition it is also possible to which being based on multiple estimated value using other way carrys out the object
The reference value of product.In this step, when participated in jointly by multiple block chain nodes generate reference value when, can to avoid by
Determination of the single block chain node (for example, corresponding to single transactional services provider) to Item Value, can more reasonably mention
For the reference value of article, and break the monopolization to reference value of single block chain node.
Step 205: participating in the block chain network to the common recognition of the reference value.For example, block chain node 101 is participated in this
The common recognition of reference value, wherein any common recognition algorithm can be used, including but not limited to: PBFT (Byzantine failure tolerance), DPoS
(commission equity proves) etc..
Step 206: based on common recognition as a result, the reference value is stored in block chain account book.Further, it is also possible to periodically
Ground generates the reference value of the article based on the estimated value information received, to refresh reference value, and participates in the block
The reference value of the refreshing is stored in block chain based on the result of common recognition to the common recognition of the reference value of the refreshing by chain network
In account book.
In some embodiments, which can have various information, including but not limited to article trading information, object
Product ownership information, article damage information, article repair message.For example, article trading information can indicate the transaction with article
The information such as (for example, dealing etc.) related information, such as both parties' information, trade date, transaction value.For example, article institute
Information of having the right can indicate the information of article ownership transfer, such as the information such as current owners, previous owner of article.
For example, article damage information can indicate the related information of the damage with article, such as damage event, place, time, impaired position
It sets, the information such as severity.For example, article repair message can indicate the related information of the maintenance with article, such as article
Maintenance, the repairing of article part and replacement information etc..In addition, Item Information can also include various other letters relevant to article
Breath.
In some embodiments, before step 201, method 200 can also include: receive the article Item Information and
Identification information, and Item Information and identification information are associatedly stored in block chain account book.In this step, by by complete
Item Information cochain is made Item Information become data trusty by net entity authentication, and the whole network participates in common book keeping operation system
It can effectively solve due to information asymmetry bring centralization industry barrier and monopolization.It is possible to further by the object of article
Product information is stored in chronological order in the block chain account book.It is in the further step, Item Information is temporally suitable
Sequence is stored in the block chain account book, is conducive to the inquiry to Item Information.For example, information is damaged for article, it can be by
The time sequencing occurred according to damage event is stored in block chain account book.
In some embodiments, step 206 may include: the estimated value when the first ratio in the estimated value information
When in the first threshold range of the reference value, which is stored in block chain account book, wherein the first ratio with
Used block chain common recognition algorithm is related.For example, being more than the block chain link of the whole network 2/3 when using PBFT common recognition algorithm
The estimated value that provides of point reference value first threshold range (for example, the 90%-110% range of reference value, that is, float
When within 10%), which is stored in block chain account book.In this step, which is stored in area
Using the market value as transaction initiator and target transaction side's inquiry article in block chain account book.
In some embodiments, if step 206 can also include: the assessment of the second ratio in the estimated value information
Value is within the scope of the second threshold of the reference value of the article, then to block chain corresponding with the estimated value of the second ratio
Node is punished, wherein the upper limit value of second threshold range is less than the lower limit value or second threshold range of first threshold range
Lower limit value be greater than first threshold range upper limit value.In this step, if there is maliciously dragging down market value or drive up
Market value block chain node (for example, if the estimated value provided reference value second threshold range (for example, ginseng
Examine the 0-45% range or 155% range above of value) within), then such block chain link point is punished (for example, can be with
It is the punishment for carrying out imposing a fine to service provider corresponding to block chain node etc).For example, in 100 block chain nodes
The estimated value that provides of 20% (that is, second ratio, correspond to 20) block chain node within the scope of second threshold, wherein
The upper limit value of second threshold range is less than the lower limit value of first threshold range or the lower limit value of second threshold range is greater than the first threshold
It is worth the upper limit value of range, then 20 block chain link points is punished.
In some embodiments, method 200 can also include: receive from target transaction side with the article phase that has intention
Associated inquiry request, the inquiry request include the identification information of the article；Identification information based on the article, from block chain account
The reference value of the article and/or at least part of Item Information are read in this；The ginseng of the article is sent to target transaction side
Examine at least part of value and/or Item Information.In this step, target transaction side (for example, purchaser) can pass through example
API (application programming interfaces) as open inquires the newest market value of the article, or inquires the Item Information (example of the article
Such as, article trading information (obtain historical trading value), article proprietary information, article damage information, article repair message
Deng).Similarly, transaction initiator can carry out similar inquiry for example, by open API.Accordingly, with respect to the article of article
Information and market value are open and transparent for both parties.
In some embodiments, method 200 can also include: that reception is associated with the article from target transaction side
Transaction, which strikes a bargain, requests, and transaction conclusion of the business request includes the identification information of the article；It generates and target transaction side on block chain
The corresponding transaction certificate of account, the transaction certificate are corresponding with the reference value of the article；It initiates to turn in block chain network
It transfers easily, to send the transaction certificate from target transaction direction transaction initiator.It in this step, can be by block chain
Transfer transactions are initiated to realize the exchange of article so that transaction initiator obtained from target transaction side it is corresponding with conclusion of the business article
Transaction certificate (e.g., including but be not limited to integral, monetary assets etc.).
In some embodiments, method 200 can also include: and be handed over after the successful execution transfer transactions based on the transfer
The user information of easy Transaction Information and target transaction side updates at least part of the Item Information of the article, and will be through
At least part of the Item Information of the article updated is stored in block chain account book, wherein the Item Information of the article
At least part includes the article trading information and article proprietary information of the article.In this step, it is shifted in successful execution
After transaction, the Item Information of the more new article on block chain is needed, for example, it is all to record new article trading information, article
Weigh information.For example, new article trading information may include both parties' information, trade date, the settlement price of the transfer transactions
Value etc..For example, new article proprietary information may include the target transaction side of article as current owners, the transaction of article
Initiator is as previous owner, so that forming an irrevocable ownership chain.
The embodiment described according to fig. 2 provides the solution of the barter based on block chain, solution tool
It has the following advantages: by Item Information cochain, so that Item Information is become data trusty, effectively solve due to information asymmetry band
The centralization industry barrier and monopolization come enhance the information openness and Item Value transparency of article swap meet, improve object

400, and using used car as article example.Current Second-hand Vehicle Transaction platform is numerous, and the management in market is very chaotic, fills
Denounce each series advertisements, and not high to the relevant transparency information of transaction, the quality of used car relies in centralization completely
The information that Jie's platform provides is as foundation, once going wrong, benefit damage side is difficult to carry out a point duty.Example 400 proposes
A kind of Second-hand Vehicle Transaction scheme based on alliance's chain, decentralization, in the example 400, alliance's chain network has management section
Point 401-405 and ordinary node 411-413, wherein each management node can be corresponding to transactional services provider (for example,
Medium platform) block chain node, each ordinary node can be correspond to transaction initiator (for example, the side of selling) or target hand over
The block chain node of Yi Fang (for example, purchaser).
For each management node in management node 401-405, the information of vehicles and identification information of vehicle can receive,
And information of vehicles and identification information are associatedly stored in block chain account book.For example, each automobile is going out for vehicle
VIN code (Vehicle Identification Number) is had when factory, can be used as the mark letter of unique identification this automobile
Breath, furthermore all spare and accessory parts of automobile may have corresponding identification information.Information of vehicles may include such as vehicle transaction
Information, vehicle ownership modification information (or vehicle ownership information), vehicle damage information (or for vehicle history accident believe
Breath), vehicle maintenance information etc..For example, vehicle Transaction Information may include transaction record of the vehicle from trading first time, such as
The information such as both parties' information, trade date, transaction value, and when oneself transaction for the first time of each vehicle, each ownership
Modification information will record in block chain account book, such as the transfer information of vehicle forms an ownership chain and irrevocable,
So that vehicle ownership modification information confidence level is higher.Vehicle history accident information cochain in chronological order, records accident
Event, place, damaged vehicle position, severity (such as tetra- grades of A, B, C, D can be divided into), with mileage travelled number, peace
Vehicle maintenance information of the replacement of full air bag, spare and accessory parts etc etc. records cochain as the historical archives of vehicle.In addition, used car
Reference value setting participate in setting jointly by the management node in alliance's chain, a specific example may is that every 60 minutes
The management node of the whole network carries out primary common ballot setting to the price of vehicle, when being more than the whole network 2/3 (for example, when using PBFT
Know together algorithm when) the estimated value that provides of node float when within 10%, management node will calculate all nodes to bid
The average of lattice and packing is recorded in block, as the market value for inquiring second-hand vehicle for dealing side.If there is malice
The node for dragging down price or pushing up price, (such as be specially the price that provides above or below finally achieving common recognition price
55%), then such node will pay for.
For the ordinary node 411-413 (such as purchaser) in alliance's chain, following operation can be executed: by open
API inquires the newest market value or newest transaction value of current used car；And intention two can be inquired by open API
The historical archives information of handcart, including but not limited to vehicle ownership information, vehicle damage information, vehicle maintenance information etc..
For the ordinary node 411-413 (such as the side of selling) in alliance's chain, following operation can be executed: by open
API inquires the newest market value or newest transaction value of current used car；When needing to sell used car, broadcast request is to entirely
In the management node of net, management node generates reference value upon receiving the request, for the used car, and reference value is deposited
It stores up in block chain account book；When successfully completing transaction, management node modifies a part of the information of vehicles of the vehicle (for example, vehicle
Transaction Information and vehicle ownership information).
Fig. 5 shows the exemplary flow 500 updated according to the Item Information of the example 400 of Fig. 4.In the exemplary flow
In 500, such as used car has VIN code abcde123, it is assumed that A is the side of selling, and B is purchaser, is successfully completing bargain transaction
Later, the ownership information of the vehicle will be registered as A- > B, that is, be stored in block chain account book (such as block 2001).Assuming that
Subsequent B is the side of selling, then the used car is resell and gives purchaser C, then the information of ownership will be registered as A- > B- > C, that is, deposit
Storage is in block chain account book (such as block 2002), and so on.
