According to the embodiment of the disclosure, the blockchain technology is utilized, the preferential conditions are associated with the preferential activities, when the preferential conditions are met, the preferential activities are automatically exchanged for clients purchasing goods, so that users can be guaranteed to obtain the preferential activities in time, meanwhile, merchants do not need to take time and effort to hold full deactivation or issue coupons, when the corresponding preferential conditions are not met, sellers can automatically obtain the preferential activities planned to be issued to the users, so that the interests of the merchants when the preferential activities are carried out but the promotion effect is not met are guaranteed, the preferential mode based on the embodiment of the disclosure can enable the buyers and sellers to win each other, further, the preferential promotion can be effectively realized by setting the preferential conditions as the transaction quantity, the client flow is improved, and the effect of commodity promotion is achieved.
Referring to fig. 1, fig. 1 is a flowchart of a blockchain-based offer method according to an embodiment of the present disclosure, where the method includes the following steps S101 to S102.
In step S101, the seller node establishes a preferential fund pool and preferential conditions based on the intelligent contract, so that each buyer node in the blockchain invests part of funds in the shopping amount required to be paid to the seller node into the preferential fund pool when shopping based on the intelligent contract.
In this embodiment, the seller node creates an intelligent contract, where the intelligent contract can agree on a preferential manner of the seller node and a payment manner of the buyer node, where the preferential manner includes creating a preferential fund pool, and returning funds in the preferential fund pool to the buyer node when a preferential condition is reached, and the payment manner includes dividing a total price to be paid into two parts of a payment amount c and a fund amount r when a transaction is generated by a merchant of the seller node by a customer, where the payment amount c is directly paid to the merchant, and the fund amount r is put into the preferential fund pool. If the preferential condition is reached, all r are returned according to the original path. The seller node establishes a pool of offer funds and offer conditions based on the intelligent contract, wherein the offer conditions may be that the total transaction amount, i.e., the transaction amount, of the merchant reaches a preset amount at the end of the transaction day, and in some embodiments, the offer conditions may also be other offer conditions set by the merchant according to its merchandise promotion goals, which is not limited by the present disclosure.
Further, the smart contract in the embodiment of the present disclosure includes:
(1) Setting transaction T { [ I ] U ]，[c→M，r→R]}
(2) Setting a return transaction T refund {[I R ]，[r i →U i ，1≤i≤S]|[t，S≥n，T i in-chain]}
(3) Setting up a cash register transaction T collection {[I R ]，[sum(r i )→M]，1≤i≤S|[t，S<n]}
(4) M pair T, T refund And T collection Signed and broadcast to the blockchain.
It will be appreciated that the seller node sets up a return transaction and a collect transaction in the smart contract, signs it, broadcasts it to the blockchain, and when the buyer appends its signature in step (7) later, the return transaction and collect transaction take effect, the buyer obtains an offer based on the return transaction and collect transaction, wherein the return transaction is that the buyer node automatically obtains the offer funds from the fund pool when the offer condition is reached, and the collect transaction automatically obtains the offer funds in the offer fund pool when the offer condition is not reached, as described in detail in the following embodiment.
(5)U i When the merchant M shops and settles, M calculates the amount c which should be paid to the merchant immediately according to the shopping amount of the ith customer Ui and (1) the preset ratio of c to r i And an amount r that can be returned if the condition is satisfied i Modifying transaction T to T i {[I Ui ]，[c i →

Description:
(A)[I U ]representing the input of the transaction T, i.e. funds owned by the payer. [ c→M, r→R]
Indicating that the amount c is paid to M and the amount R is paid to R. Wherein M is the merchant and R is the public fund pool.
(B)[t，S≥n，T i in-chain]Is transaction T refund The condition that is satisfied, i.e. after time T, if for T refund The number S of signed (different) clients reaches or exceeds a preset n,
and the clients participating in the signature generate at least one transaction T i Transaction T refund Takes effect.
(C)[t，S<n]Is transaction T collection Effective conditions, i.e. after time T, if applied to T collection If the number S of signed (different) clients does not reach the preset n, T collection Takes effect.
(D) (4) although T is now refund And T collection Broadcast to the blockchain is directly ignored by the blockchain system, i.e., both transactions are considered invalid because time t has not yet been reached. But both transactions can be seen by the overall node. U in this way (7) i Can be directly to T refund And T collection And (5) adding a signature.
(E) Ui vs T in (6) i The signature is sent to M, and then wait until (8) M pairs will T i Broadcast to blockchain for signature branching to occur, i.e. if two different clients U i And U j Possibly at the same time to T refund And T collection Appending the signature, which creates a branch. This can be controlled by M pairs of T i To avoid. I.e. M and T again i Will not broadcast T to the blockchain i+1 Is sent to U i+1 。
(F) If final T refund Broadcast again to blockchain after time T and take effect, then according to all transactions T i [ I ] in the record of (2) Ui ]And ri, substituting it into r i Ui, thereby making all U i All get the respective amount r to be returned i 。
(G) If final T collection Is broadcast again to the blockchain after time t and takes effect,
will directly [ I ] R ]The total amount of (a) is paid to M.
Since (8) follows (7), M can ensure U i At the same time to T refund And T collection Signing and broadcasting to blockchains, i.e. to T refund And T collection The number of signatures is always the same. In some embodiments, the purchase amount is calculated by determining each buyer node pair T refund And T collection The number of signatures is more efficient and quicker in calculation mode, and the data can be effectively guaranteed not to be tampered.
In step S102, when the current transaction situation reaches the preferential condition, making each buyer node acquire funds in the preferential fund pool based on the intelligent contract;
in step S103, when the current transaction situation does not reach the preferential condition, the seller node is caused to acquire funds in the preferential fund pool based on the intelligent contract.
It should be noted that, the current transaction situation indicates a transaction situation that meets the judgment condition, and is different from a transaction set in the intelligent contract such as the first payment transaction and the second payment transaction in the embodiment.
In this embodiment, when the current transaction condition reaches the promotion condition, the buyer node automatically acquires funds in the promotion fund pool, and when the current transaction condition does not reach the promotion condition, the seller node automatically acquires funds in the promotion fund pool.
Referring to fig. 2, fig. 2 is a flowchart of a blockchain-based offer method according to another embodiment of the present disclosure, and based on the above embodiment, after the seller node establishes the offer fund pool and the offer condition based on the intelligent contract, the method further includes the following steps S201-S203.
In step S201, the seller node or any buyer node determines whether the current time reaches a preset preferential time, and if the current time reaches the preset preferential time, step S202 is executed;
specifically, the preset preferential time is a time point when the merchant will redeem the preferential to the user, for example, the preferential time of the merchant starts at a certain time point which is 10 days from 1 day, and ends at a time point which is 10 days later than 3 days in the same month, the preset preferential time can be set to be equal to the time point which is 10 days later than 3 days, and the seller node or any buyer node judges whether the preset preferential time is reached, wherein the preset preferential time can be broadcasted into the blockchain by the seller node.
In step S202, the seller node or any buyer node determines whether the current transaction situation reaches the preferential condition, if so, the step S102 is entered into where the buyer node obtains the funds in the preferential fund pool, and if not, the step S103 is entered into where the seller node obtains the funds in the preferential fund pool.
When judging that the preferential condition is not met, the seller node acquires the preferential funds in the preferential funds pool, compared with the prior art, the preferential activity carried out by the merchant fully releases the undirected user during the preferential period or before the preferential activity, and the problems that the preferential activity carried out by the merchant consumes a great deal of manpower and material resources and time but does not reach the promoting effect at last are likely to exist. Further, before the seller node establishes the preferential fund pool and preferential conditions based on the smart contract, the method further comprises the following steps:
the seller node setting a first collection transaction and a second collection transaction in the smart contract; the first collection transaction is used for indicating that the current transaction condition reaches the preferential condition, the buyer node obtains funds in the preferential fund pool, and the second collection transaction is used for indicating that the current transaction condition does not reach the preferential condition, and the seller node obtains funds in the preferential fund pool;
the seller node signs the first and second collection transactions and broadcasts to a blockchain for additional signing by the buyer node for consensus of the transactions.
In this embodiment, the first collection transaction and the second collection transaction are set up in the smart contract, and are used to instruct the seller and the buyer to obtain the funds in the funds pool, and broadcast the funds to the blockchain, so that the seller node and each buyer node reach consensus, and each buyer node participating in the preferential activity is ensured to automatically obtain the funds in the funds pool or the seller node automatically obtains the funds in the funds pool when the specific preferential condition arrives.
Wherein the first payment transaction may correspond to a return transaction T in the smart contract example mentioned in the previous embodiment refund The second collection transaction may correspond to collection transaction T in the smart contract example collection 。
Further, after the seller node establishes the preferential fund pool and preferential conditions based on the intelligent contract (step S101), and before the seller node or any buyer node determines whether the current time reaches the preset preferential time, the method further comprises the following steps:
the seller node or any buyer node respectively calculates the fund amount to be input into the preferential fund pool and the payment amount to be paid to the seller node in the shopping amount to be paid to the seller node by the buyer nodes according to the shopping amount to be paid to the buyer nodes;
the seller node sets a first payment transaction according to the fund amount and the payment amount, signs the first payment transaction and then sends the first payment transaction to a corresponding buyer node, so that the buyer node signs the first payment transaction additionally and returns the first payment transaction to the seller node, signs the first collection transaction and the second collection transaction additionally after signing the first payment transaction additionally, and broadcasts the first collection transaction and the second collection transaction to a blockchain;
after the seller node monitors that the buyer node signs the first and second collection transactions additionally, the first payment transaction is broadcasted into a blockchain, so that the buyer node pays corresponding payment amount to the seller node, and simultaneously, funds corresponding to the corresponding funds amount are put into the preferential funds pool.
In this embodiment, the first payment transaction is set by the seller node according to the fund amount and the payment amount, and the first payment transaction is signed to enable the buyer node to be additionally signed, the buyer node further signs the first payment transaction and the second payment transaction, the seller node broadcasts the first payment transaction to the blockchain, the first payment transaction is effective, and the preferential fund is ensured to be acquired in a contracted manner.
Also, in some embodiments the determination of the purchase transaction amount is made by calculating the signatures of the first and second payment transactions, in order to avoid signature branching, the buyer node first signs the first payment transaction to the seller node, and then waits until the seller node signs the first payment transaction, and then broadcasts the first payment transaction to the blockchain, where the branching occurs in order to sign, i.e., if two different customers may sign the first and second payment transactions at the same time, which creates a branching. This may be avoided by the seller node pair controlling the first payment transaction, i.e., the seller node does not send the first payment transaction calculated for the other customer to the other customer before broadcasting the first payment transaction to the blockchain, as may be appreciated in connection with the smart contract description (E) above.
Further, before the seller node establishes the preferential fund pool and preferential conditions based on the smart contract, the method further comprises the following steps:
the seller node setting up a second payment transaction in the smart contract;
the seller node or any buyer node respectively calculates the fund amount to be put into the preferential fund pool and the payment amount to be paid to the seller node in the shopping amount to be paid to the seller node by the buyer node according to the shopping amount to be paid to the buyer node, comprising:
and the seller node or any buyer node respectively calculates the fund amount to be input into the preferential fund pool and the payment amount to be paid to the seller node in the shopping amount to be paid to the seller node by each buyer node according to the second payment transaction and the shopping amount to be paid to the buyer node by each buyer node.
It will be appreciated that the second payment transaction is used to indicate the manner of calculating funds to be placed in the preferential fund pool, and by setting the second payment transaction in the smart contract, the seller node or any buyer node calculates the funds to be placed in the preferential manner, which is beneficial to guaranteeing fairness among the buyers and sellers.
Further, in connection with the smart contract described above, if it is desired that the amount ultimately returned to the customer is related to the total transaction amount V, the total transaction amount S, and the preset discount rate r/(c+r), T may be determined refund Change to T refund {[I R ]，[f(S，V，c，r)→Ui，r i -f(S，V，c，r)→M，1≤i≤S]|[t，S≥n，T i in-chain]}. Where f (S, V, c, r) is a function of the 4 parameters S, V, c, r.
In this embodiment, the seller node or any buyer node further determines whether the preferential condition is reached, in one implementation, the preferential condition is mainly related to the total amount of purchase transaction actually generated, by associating the total amount of purchase transaction actually generated with the preferential activity, and automatically redeeming the preferential when the preferential activity is ended, specifically, the seller node or any buyer node determines whether the current transaction condition reaches the preferential condition, including the following steps:
the seller node or any buyer node obtains the purchase transaction total amount of each buyer node based on the intelligent contract shopping from a blockchain;
the seller node or any buyer node judges whether the total amount of the purchase transaction reaches a preset amount;
if the total amount of the purchase transaction reaches the preset amount, the seller node or any buyer node judges that the current transaction condition reaches the preferential condition;
if the total amount of the purchase transaction does not reach the preset amount, the seller node or any buyer node judges that the current transaction condition does not reach the preferential condition.
Further, the purchase transaction total amount is judged by judging the node pair T of each buyer refund And T collection The signature quantity is more efficient and quick in judging mode, the authenticity of the data can be effectively guaranteed, the data cannot be tampered, the efficiency of the buyer for acquiring the preferential is improved, and the user experience is further improved.
With the development of blockchain technology, a scheme for issuing coupons to clients by using blockchain technology is also presented, but the coupons are issued, issued and used mainly by using blockchains. The method and the system have the advantages that the actually generated transaction quantity is not related to the preferential activity, and the preferential is automatically redeemed when the preferential activity is finished on the same day, and the client flow can be effectively improved by relating the preferential to the actually generated transaction quantity, so that the method and the system provide a trigger for commodity promotion for the entity storefront.
For example, a mall's offer will begin at 10 am on 1 day of the month and end at 10 pm on 3 days of the same month. The preset rule (i.e., preferential condition) is that on the basis of routine full deactivation, if the total transaction number in the middle reaches 10 ten thousand, all transactions will obtain a return point of 5% of the actual transaction amount. The first completes a transaction with 100 yuan of money in the amount of money in the afternoon of 1 day; by 10 days and nights of the same month, the accumulated transaction amount of the market is 100 ten thousand yuan, wherein 95 ten thousand yuan is already posted to the account of the market, and the other 5 ten thousand yuan is in the fund pool R. (a) If the trade (different) clients accumulated in the market are more than 10 ten thousand times by 10 days late on 3 days of the same month: the market (or a client B) divides T1 at 10 points 3 days later refund Rebroadcast to zoneBlock chain then a refund of 5-membered will be obtained. Other customers cumulatively obtain refunds 49995 yuan. The market finally obtains 95 ten thousand yuan; (b) If the market is 10 days late by 3 days of the same month, the accumulated number of transaction (different) clients in the market is less than 10 ten thousand: the market (or a client B) divides T1 at 10 points 3 days later collection Again broadcast to the blockchain, the mall will acquire 5 ten thousand yuan in the fund pool, and the mall will eventually acquire 100 ten thousand yuan.
Based on the same technical concept, the embodiments of the present disclosure correspondingly further provide a vendor node device, as shown in fig. 3, where the vendor node device includes:
an offer module 31 configured to set up an offer fund pool and offer conditions based on an intelligent contract, so that each buyer node in a blockchain invests a part of funds in a shopping amount that needs to be paid to the seller node into the offer fund pool when shopping based on the intelligent contract, so that each buyer node obtains funds in the offer fund pool based on the intelligent contract when a current transaction condition reaches the offer conditions; the method comprises the steps of,
an acquisition module 32 is configured to acquire funds in the preferential fund pool based on the smart contract when the current transaction situation does not reach the preferential condition.
In one embodiment, the seller node apparatus further comprises:
the judging module is used for judging whether the current moment reaches the preset preferential moment after the preferential fund pool and the preferential condition are established by the preferential module;
the judgment module is further configured to continuously judge whether the current transaction condition reaches the preferential condition when judging that the current time reaches a preset preferential time, and if so, enable each buyer node to acquire funds in the preferential fund pool based on the intelligent contract;
