Description
Technical field
The present invention relates to buyer inversely fix a price field more particularly to a kind of reverse pricing method of buyer based on block chain and
System.
Background technology
Currently, with the development of economy, the phenomenon that social materialss commodity and service provision are more and more abundant, and supply exceed demand exists
It is increasingly prominent in many industries, actuals and the superfluous inexorable trend for being increasingly becoming era development of service, resource vacancy phenomenon
It becomes increasingly conspicuous.
In commodity and the service epoch that there is a serious shortage in the supply, supply falls short of demand for commodity and service, and market belongs to the seller, unified by the seller
Price, buyer then passively selection call purchase commodity or service, this pricing model promote the seller enthusiasm for production or
Enthusiasm is serviced, great impetus is played to economic and society development.
However, the epoch superfluous in actuals and service, the pattern of seller's unified price can then hinder economic and society
Development.Identical actuals or service, for different people, they are ready that the price is also different, and
Over time, actuals or the marginal use value of service are also different, and unified price will necessarily hinder substance
The circulation and utilization rate of commodity or service.
In view of this situation, the pattern of call sale is come into being, and is fixed a price by buyer, and the seller bids, finally
By receiving the seller of call sale actuals or service are provided for the buyer.The pattern that buyer inversely fixes a price can encourage buyer
It is traded, excites the purchase enthusiasm of buyer, stimulate the purchasing demand of buyer.In addition, the seller can be promoted in a certain range
The price of actuals or service is adjusted, the resource distribution for promoting the actuals of the seller or service to be optimized obtains most
Big benefit.
The existing reverse pricing system of buyer, be by internet platform system centre management, plateform system to buyer and
The many kinds of parameters of seller's input is calculated, and after buyer inputs buying offer condition, offer is pushed to potential sell by plateform system
Side, the potential seller conclude the transaction after receiving the buying offer of buyer.
The system management platform of centralization has complete control to the transaction of both parties.The Transaction Information quilt of both parties
Encryption, concluded price are stored by secret, which can not be by public awareness, this has resulted in the opaque of concluded price,
The interests that both parties may be damaged, in this process of exchange, the system management platform of centralization then at it is maximum by
Benefit side.For example, system platform can extrapolate the buyer for lattice of being ready to make the highest price according to many kinds of parameters of buyer, and according to the seller's
Many kinds of parameters extrapolates the seller for being ready lowest price, and thus the platform of centralization just obtains maximum value, and buys and sells double
The Fang Juncheng aggrieved parties of interests.Therefore, the centralized management platform of the reverse pricing system of this buyer, no normal direction masses provide
Open and clear platform commission algorithm, and then both parties is allowed to be in unfavorable status, to a certain extent, cause social wealth
Rich stream expands social gap between the rich and the poor, is unfavorable for building open and clear wealth of society mechanism to centralized management platform.
In addition, the system management platform of centralization take in process of exchange measuring and calculating price, displaying price, transaction bring together,
The roles such as payment guarantee, there are the defects of platform dependent for this mode, and turnover cannot clear in real time.To a certain extent,
Increase transaction cost and risk.
On the other hand, if the system management platform of centralization is attacked or platform operation person has the behaviors such as fraud,
The transaction of both parties is then very dangerous.

Include the following steps：
First client receives buyer's element (or purchase element or commercial factor), and buyer is generated according to buyer's element
Contract, buyer's contract are recorded in block chain, and buyer's element includes buyer identifier, the first element and buyer's price, and first wants
Element includes trade name to be bought.
Specifically, buyer interacts by the first client after server log success with server, in the first visitor
Buyer's element can be inputted on the end of family, receive transaction response results, payment transaction expense and transaction procedure take, send request
Deng.After buyer's element of its required commodity is arranged in buyer in the first client, buyer's element is generated buyer by the first client
Contract, buyer's contract contain buyer's element, and the first client is connect with the node in block chain network, therefore buyer's contract can
It is recorded in block chain, buyer also directly can exchange data by the first client with block chain, such as inquire contract dataset, sell
Square account of the history, trading situation and execute contract, transaction verification etc..First client can be mobile terminal, such as mobile phone, pen
Remember this computer, tablet computer；Can also be fixed terminal, such as PC machine terminal.Buyer's element includes：The first element and buyer's valence
Lattice.The first element includes trade name to be bought, and can be：The tangible trade name such as air ticket, hotel, hotel can also be
It the invisible trade name (commodity are properly termed as servicing at this time) such as picks, can be not only existing tangible trade name but also have
Invisible trade name, the present embodiment is to this without limiting.The first element includes but not limited to：The quantity of commodity, type, etc.
Grade executes place, time, contract life cycle.Buyer identifier is for confirming that user is buyer.
Second client receives seller's element (or commercial factor to be sold), generates seller's contract according to seller's element, sells
Fang Heyue is recorded in block chain, and seller's element includes vendor identification, the second element, buyer's price, and the second element includes waiting for
Sell trade name.
Specifically, the seller interacts by the second client after server log success with server, in the second visitor
Can input seller's element on the end of family, receive transaction application, response transaction, receive tranaction costs and payment transaction service charge,
Send request etc..The seller be arranged on a second client its for seller's element of commodity after, the second client is by seller's element
Seller's contract is generated, seller's contract contains seller's element, since the second client is connect with a node of block chain network,
Seller's contract may be recorded in block chain, and the seller also directly can exchange data by the second client with block chain, such as inquire
Contract dataset, seller's account of the history, trading situation and execute contract, transaction verification etc..Second client can be mobile whole
End, such as mobile phone, laptop, tablet computer；Can also be fixed terminal, such as PC machine terminal.Seller's element includes：Second wants
Element and price of the selling party.Second element includes trade name to be sold, and can be：The tangible trade name such as air ticket, hotel, hotel
Claim, can also be the invisible trade name (commodity are properly termed as servicing at this time) such as to pick, and can be existing tangible quotient
The name of an article claims and has invisible trade name, and the present embodiment is to this without limiting.Trade name to be sold need to be in title one to be bought
It causes, such as can be just the same, the second element includes but not limited to：The quantity of commodity, grade, executes place, time, conjunction at type
About life cycle etc..The quantity of second client is preferably several, and each second client generates seller's contract at this time.It sells
Side's mark is for confirming that user is the seller.
Server judges whether meet the buyer's contract read from block chain from the seller's contract read in block chain,
If being judged as meeting, then the intelligent contract concluded the transaction is generated, intelligent contract is recorded in block chain.
Specifically, server is connect with block chain network, is receiving the friendship for coming from the first client and the second client
Easily after request, buyer's contract and seller's contract are read respectively from block chain, and buyer's contract and seller's contract are recorded in clothes
It is engaged in device.Server judges whether seller's contract meets buyer's contract, if meeting (or successful match), generation is concluded the transaction
Intelligent contract, intelligent contract is recorded in block chain, then notifies the first client (it corresponds to buyer) and/or the second visitor
Family end (it corresponds to the seller) is merchandised successfully, has preferentially not only notified the first client, but also notify the second client.Server is in buyer
When contract meets with seller's contract, a certain number of tokens are locked, the payment system of server transfers token when transaction is completed,
Turnover is cleared in real time.Server is properly termed as contract system.When seller's contract does not meet buyer's contract,
Server can also judge whether other seller's contracts meet buyer's contract, if buyer sets contract life cycle, in contract
Judge whether seller's contract meets buyer's contract always in life cycle, until success.Likewise, for judging that buyer's contract is
The no seller's contract that meets is also the same.When containing contract life cycle in element, in contract life cycle, with the time
Passage, seller's contract may change or the new seller enter, buyer can according to the variation of seller's contract, adjust from
Oneself contract setting or uncomfortable integration about waits for contract successful match.
Commercial factor is set by both parties, buyer's contract and seller's contract record in block chain, and block chain is
The distributed network system (DNS) of centralization is concluded the transaction by node common recognition and intelligent contract, and avoid centralization in this way is
The control that platform under the overall leadership merchandises to both parties, it is thus also avoided that centralization platform is attacked；It can be according to buyer's contract model
It is trapped among in contract life cycle and searches qualified seller's contract, buyer's contract is matched with seller's contract, generates transaction intelligence
Contract is concluded the transaction, and solves the problems, such as the mutual trust of buyer both sides, and the circulation of commodity and service is promoted to use；Server is in buyer
When contract is matched with seller's contract, a certain number of tokens are locked, the payment system of server transfers token when transaction is completed,
Turnover is cleared in real time.
In practice, buyer is due to may not be the price quotations for being well understood by commodity to be bought, thus be not easy as early as possible with the seller
Conclude the transaction or it is extremely difficult conclude the transaction with the seller, therefore, in order to improve transaction success rate, on the basis of the above embodiments, ginseng
See Fig. 3,5, after receiving the first element, the first client judges whether to receive price suggestion instruction the first client, if
It is judged as receiving, then receives the Recommended Price that the first element based on reception of server return generates, Recommended Price is made
Otherwise buyer's price of buyer's input is received for buyer's price.
Specifically, the first client prompts whether buyer user sends Recommended Price request after receiving the first element,
If receiving the request of buyer user, the first element and the request are sent to server together, otherwise, it is directly defeated to receive buyer
The price entered.After server receives the request, price corresponding with the first element is extracted from block chain according to the first element
It is recommended that data model indexes, then extraction price corresponding with price suggestion data model index suggests data from server
Model suggests that data model and historical trading data corresponding with the first element generate the suggestion of the first element using the price
Price, and it is sent to the first client.Buyer may be selected to receive this Recommended Price as buyer's price, also may be selected to suggest accordingly
The price of price adjustment oneself input is as buyer's price.Server can also read price according to the first element from block chain
It is recommended that data model, then utilize price suggest data model and historical trading data corresponding with the first element generate this first
The Recommended Price of element.Public information is recorded in block chain in buyer's contract, and note is encrypted in sensitive information in buyer's contract
Record is in server.Then buyer's contract matches server with seller's contract accordingly, if matching (or brining together) success, leads to
Know and buy, sell both sides and merchandise successfully, i.e., buyer can ideal price purchase purchase commodity.If there is no can matched seller's contract,
Notice buys, sells top Fail Transaction.Since price suggests that data model index is placed in block chain, which can not distort, because
This buyer and the seller can be checked and be supervised the model by the index, and the profit for buying, selling both sides can will not be injured with assurance model
Benefit, decentralization.
In practice, the seller is due to may not be the price quotations for being well understood by commodity to be sold, thus be not easy as early as possible with buyer
Conclude the transaction or it is extremely difficult conclude the transaction with buyer, therefore, in order to improve transaction success rate, on the basis of the above embodiments, ginseng
After seeing that Fig. 7, the second client receive the second element, the second client judges whether to receive price suggestion instruction, if judging
To receive, then the Recommended Price that the second element based on reception of server return generates is received, using Recommended Price as selling
Otherwise square price receives the price of the selling party of seller's input.
Specifically, the second client prompts whether seller user sends Recommended Price request after receiving the second element,
If receiving the request of seller user, the second element and the request are sent to server together, otherwise, it is directly defeated to receive the seller
The price entered.After server receives the request, price corresponding with second element is extracted from block chain according to the second element
It is recommended that data model indexes, then extraction price corresponding with price suggestion data model index suggests data from server
Model suggests that data model and historical trading data corresponding with the second element generate the suggestion of second element using the price
Price, and it is sent to the second client.The seller may be selected to receive this Recommended Price as buyer's price, also may be selected to suggest accordingly
The price of price adjustment oneself input is as buyer's price.Server can also read the seller according to the second element from block chain
Price suggests data model, and price of the selling party is then utilized to suggest that data model and historical trading data corresponding with the second element are given birth to
At the Recommended Price of second element.Sensitive information, which is encrypted, in seller's contract is recorded in server.Then server evidence
This seller's contract is matched with buyer's contract, if matching (or brining together) success, notice buy, sell both sides and merchandise successfully, that is, sell
Side can ideal price purchase sell goods.If there is no can matched buyer's contract, notice buy, sell top Fail Transaction.
Server judges not meet buyer's contract by the seller's contract read that (or seller's contract and buyer close from block chain
About match unsuccessful), then by characterize Fail Transaction message informing give the first client and the second client, that is, notify buyer and
Seller transaction fails, and the message for characterizing Fail Transaction is recorded in block chain, is so conducive to the transparence of transaction, will not injure
Buy, sell the interests of both sides.
After brining buyer's contract and the failure of seller's contract together for the first time, buyer fails to buy commodity to be bought, and the seller fails to sell
Go out commodity to be sold, therefore, in order to improve transaction success rate, on the basis of the above embodiments, referring to Fig. 4,6, server is being sentenced
Disconnected buyer's contract and seller's contract are after not meeting, the seller's contract recommended to be sent to the first client, if receiving first
The conclusion of the business instruction that client returns, then generate intelligent contract, otherwise, buyer's floating price is sent to the first client, if receiving
The buyer's floating price contract generated to the first client according to buyer's floating price and the first element, buyer's floating price contract packet
It includes：The first element and buyer's floating price, then judge whether seller's contract meets buyer's floating price contract, if being judged as according with
It closes, then generates the intelligent contract concluded the transaction, and notify to the first client and/or the second client, if being judged as not meeting,
The message informing of Fail Transaction will then be characterized to the first client and the second client, wherein intelligent contract and buyer's floating price
Lattice contract is recorded in block chain.
Specifically, if there is no can matched seller's contract, server is searched in server itself or block chain possibility
Meeting seller's contract expected from buyer, recommends buyer for its selection, i.e. buyer cannot buy commodity with expected ideal price, but
In the presence of commodity expected from buyer may be met.If buyer receives seller's contract that the possibility of server recommendation meets, bring together into
Work(, notice buy, sell both sides, i.e. buyer receives the commodity transaction more than initial expected, strikes a bargain immediately.It may symbol if buyer does not receive
Seller's contract of conjunction, then server is to the first client transmission buyer's floating price, and to prompt buyer, it can choose whether to hold
Whether row floating price contract mechanism according to floating price algorithm resets commodity price, if selection is, server is from area
Floating price algorithm corresponding with the first element is read in block chain, and accordingly generates buyer's floating price contract, buyer's floating price
Lattice contract includes：The first element and buyer's floating price, then match with seller's contract again, to improve purchase success rate, or
Person's selection does not execute floating price, i.e. fixed factors contract mode.The result of buyer's selection generates buyer's contract and is recorded in area
It in block chain, and is recorded in server, contract is waited for execute.In contract life cycle, over time, seller's contract
It may change or the new seller enters, buyer according to the variation of seller's contract, can adjust the contract setting of oneself, or
Uncomfortable integration about waits for contract successful match.The mode that floating price algorithm is recorded in block chain may refer to price and suggest number
