Description
Technical Field
The invention belongs to the technical field of block chains, and particularly relates to an auction method based on a block chain.
Background
The current mainstream auction forms include english auction, dutch auction, first price sealed auction and vycorrying. The english auction, the most popular of which is discussed herein. English auctions, also known as open price auctions. Buyers disclose mutual bids, each bid being higher than the previous bid. The most significant feature of this auction is that the current highest bid is always open to potential buyers.
To complete the auction process, intervention by a third party credit agency is often required, which requires a high notary fee and also requires consideration of whether the third party agency is trusted. Therefore, to overcome the above disadvantages, we can use the non-tamperproof property of the blockchain to replace the third party credit agency, and complete the auction process without the third party credit agency.
The blockchain is a technical solution similar to a non-relational database, and compared with a traditional database, the blockchain has the characteristic of being not falsified. The block chain is composed of a number of blocks. Each block stores a number of transaction data (messages). The data of each message and the processed message in the block are subjected to Hash calculation (Hash Function), so as to obtain a corresponding Hash value. Thus, any change to any message within a block will result in a subsequent change to the hash value. Thus, the hash value within a chunk can be used to verify the validity of the chunk data and to link the next message. The processing mode of the blocks is similar, namely, hash calculation is carried out on the hash value of each block and the processed block to generate a new hash value, and a layer-by-layer nested relation is formed. If the data in any chunk is modified, it will not match the hash stored in the next blockchain, resulting in a discrepancy. The data stored in the blockchain cannot be tampered with. The block chain technology is applied to the auction process, so that participation of a third party can be reduced, and fairness and effectiveness can be guaranteed.
In the prior art, as the chinese patent publication with publication number CN106682984A, publication time of 2017, 5, 17 and title of "block chain-based transaction processing method and system", a block chain-based transaction processing method and system are disclosed, a block chain-based transaction processing method and system are constructed for one block chain network, and a transaction split control system is constructed for each participant of the block chain network; the method comprises the following steps: when a user initiates a transaction request to a participant in the blockchain network, a transaction flow distribution control system of the participant acquires preset type transaction parameters of the transaction request, determines the identification of the parallel blockchain network corresponding to the preset type transaction parameters according to the prestored transaction flow distribution control parameters and based on a predetermined analysis rule; and the transaction shunting control system of the participant takes the parallel blockchain network corresponding to the determined identifier as a target blockchain network for executing the transaction request, and sends the transaction parameters corresponding to the transaction request to the target blockchain network for transaction processing.
Further, as disclosed in chinese patent publication No. CN106845960A, published in 2017, 6/13/h, entitled "block chain-based secure transaction method and system", a block chain-based secure transaction method and system is disclosed, which includes: the method comprises the steps that a supervisor writes a digital certificate and a first public key corresponding to the digital certificate into an intelligent contract of a block chain corresponding to an asset type to be supervised, so that all organizations having an asset account under the asset type can obtain the first public key of the supervisor through the digital certificate, and an addition homomorphic secret key for homomorphically encrypting the balance of the asset account is generated; when the supervisor checks the balance of the new account of the transaction party, the public key in the public-private key set corresponding to the new account is acquired, an addition homomorphic secret key is generated according to a supervision private key corresponding to a preset secret key exchange protocol and the public key in the public-private key set based on the supervisor, and the balance of the new account encrypted by the new account is decrypted by using the generated addition homomorphic secret key.
None of the above-mentioned solutions is a solution for solving the auction process problem.
Disclosure of Invention
The invention aims to provide a block chain-based auction method which ensures the fairness of the auction without a third-party credit institution, ensures the certain compulsory auction result and saves the related fairness fee due to the participation of the third-party credit institution.
An auction method based on a block chain is characterized by comprising the following steps:
a preparation link: establishing a block chain for auction, issuing auction subject matter information to the block chain by an auctioneer, issuing a guarantee by the auctioneer through the block chain, and issuing a transaction application in the block chain; after confirming the auction bidding object and the auction participants, the auctioneer sends a transaction warranty to the auction participants through the blockchain and issues a public auction deposit to the blockchain;
an auction link: the auctioneer sends a promise of refunding the bid for the non-winning bid to the auction participants participating in the auction through the block chain, the auction participants release auction guarantee funds through the block chain and auction through the block chain; after bidding is finished, if the auctioneer does not disclose successful bidders and the highest bidding price, the auctioneer obtains compensation according to the transaction warranty; if the auctioneer discloses the successful auctioneer and the highest bid, the auction link is successful;
and in the payment link, the successful auction participants finish payment and select to confirm the receiving or returning of goods after obtaining the bidding objects, thereby finishing the auction.
In the preparation link, in order to obtain qualification for participating in the auction, an auction user needs to issue a transaction request containing a signature and auction funds to a blockchain; the auctioneer selects the auction participants, signs the transaction requests of the selected auction participants, issues the transaction requests together with the public auction margin in the blockchain, and issues the transaction warranty with the signature to the selected auction participants.
In the preparation link, the auctioneer sends a transaction security certificate to the participants of the auction through the blockchain and issues a public auction margin to the blockchain, namely, a secret value s is generated in the blockchaincAnd thereby generating a hash calculation hc＝H(sc) And issuing the transaction guarantee book signature and the open bidding deposit together into the block chain, if the auctioneer does not open the secret value s after the auction is overcI.e., the auctioneer is deemed to violate the auction process, the seller loses its public bidding margin.
In the auction link, the participants of the auction release their own bid prices to the auctioneers and the block chain, after the auction is over, if the auctioneers disclose successful participants of the auction and the highest bid, the auction is successful, and the participants who are not successful in the auction withdraw their auction funds; if the auctioneer does not publicly auction successful bidders and the highest bid price deems the auction failed, all the auctioneers obtain the public auction margin of the auctioneer according to the transaction warranty as compensation and retrieve the auction fund.
If the auction link is successful, the successful auctioneer initiates payment through the block chain and requires the auctioneer to issue a refund promise of transaction failure to the block chain, and the failed auctioneer withdraws the bid guarantee money according to the refund promise of not winning a bid; the auctioneer issues a transaction failure refund commitment into the blockchain and opens the transaction.
The successful auction bidder initiates payment through the blockchain and requires the auctioneer to issue a transaction failure refund promise and request transaction to the blockchain, the transaction request and the transaction promise are issued to the blockchain, the auctioneer is required to initiate transaction and guarantee to the blockchain, if the auction process is not completed, the seller loses the guarantee of the transaction, and the buyer loses the transaction promise.
The transaction commitment fund is used for guaranteeing that the successful auction bidder does not sign after receiving the goods, and if the successful auction bidder does not sign after receiving the goods, the transaction commitment fund is lost to generate the transaction commitment fund during transaction.
In the payment link, the successful auction bidders issue transaction commitment funds through the blockchain and require the auctioneers to issue transaction failure refund commitments to the blockchain, and the auctioneers issue transaction failure refund commitments and commitment funds to the blockchain; if the successful auction bidder pays the remaining money and obtains the object to complete the sign-in, the transaction is completed, and the auctioneer withdraws the commitment money; if the successful auction bidder does not obtain the bidding object and the transaction is not completed, the successful auction bidder takes back the transaction commitment fund and the buyer loses the commitment fund.
The successful auction bidder finishes payment and obtains the bidding object, and if the successful auction bidder is not satisfied with the bidding object, the successful auction bidder chooses not to publish transaction completion to the blockchain and enters a return flow; if so, the transaction completion is posted to the blockchain.
The invention has the following beneficial effects:
the invention provides an auction method based on a block chain, which is characterized in that auction persons, auctioneers, bidding objects, promise funds, guarantee funds and the like in the auction are all placed in the block chain by establishing the block chain for auction, the auctioneers and the bidding objects are issued and confirmed through the block chain by using the block chain technology, the guarantee funds of each party are paid into the block chain, bidding, the promise funds and the like in the auction process are also placed in the block chain, the auction result is guaranteed to have certain compulsory property without a third party credit institution, meanwhile, the related fair fees are saved due to no participation of the third party credit institution, meanwhile, the block chain technology is used for realizing an online virtual transaction method, the transaction form of virtual money such as bitcoin is seemingly from users to users, and the virtual money is actually circulated among transactions, each transaction must have an input (input) and an output (output), and each transaction can use the output generated by the last transaction as an input to generate a new output, e.g., transaction TxThe generated output can be used by the next transaction, transaction T, when it satisfies the Boolean function defined by its out-scripty1And transaction Ty2GeneratingOutput of is transaction TxInput, two input-scripts represent a legal use transaction Ty1And transaction Ty2Information of the generated output.
Secondly, in order to obtain qualification for participating in auction, each auction participant needing to participate in auction submits an application for participation to an auction party, auction funds are used for ensuring that the auction participants at least have funds, and the auction participants select a certain number of buyers to participate in auction according to the auction funds and information such as credit levels of the auction participants and the like and send signature information to the buyers for confirmation and issue a guarantee to the blockchain at the same time, so that the buyers can certainly withdraw the auction funds after auction failure; the hash value is a unique and extremely compact representation of a piece of data, if a piece of plaintext is hashed and even if only one letter of the piece is changed, subsequent hashes will produce different values, and it is computationally infeasible to find two different inputs that are hashed to the same value, so the hash value of the data can verify the integrity of the data, and it is very effective for fast-lookup and encryption algorithms.
The auction method based on the blockchain further places all auction links and payment links in the blockchain environment, can further guarantee the security in the auction process, and can also be applied to online virtual currency transaction to enhance privacy and confidentiality by introducing a Hash algorithm.

Example 3
A blockchain-based auction method, comprising the steps of:
1. each person who needs to participate in the auction submits an application for participation to the auction party, and the submission method is to publish an application transaction in a block chain and require a seller s to sign a return transaction before signing and publishing the application transaction;
2. after selecting the buyer to participate in the bidding, the seller signs the open _ max transaction and publishes it into the blockchain, and the signed open _ max _ paydeposing transaction is sent to the buyer. This set of transactions is used to ensure that the seller needs to disclose the transaction results within a certain time, otherwise the seller will lose funds for the open _ max transaction;
3. each buyer bids by issuing a put money transaction in the blockchain, the funds in which correspond to a subscription. And requiring the seller to sign a putmeney i _ payback transaction before issuing the transaction in the blockchain, wherein the putmeney i _ payback transaction is used for recovering funds, if the seller does not perform subsequent operations after a certain time and discloses s, the funds are recovered, and the seller signs and issues the putmeney i transaction after signing the putmeney i _ payback transaction;
4. the seller generating a secret scAnd thereby generate an hc＝H(sc) And signing and publishing open _ s transactions into blockchains, one of the conditions for using funds for open _ s transactions is to publish a secret s so that hcH(s). The seller signs the transaction open _ s _ paydepots transaction for each group of buyers, leaving the seller atNot publish scSo that a certain amount of money is lost;
5. the seller publishes and signs the open _ max _ getback _ money transaction in step 2 in the blockchain, which is used to reclaim funds in the open _ max transaction. The non-winning buyer withdraws funds in its put-money transaction with the put-moneygiveback transaction;
6. if the seller does not disclose the max value, the open _ max _ paydeposide transaction is effected to participate in bidding for the buyer to obtain compensation;
7. generating a puttermoney transaction by a winning buyer for paying the residual money, and signing and issuing the transaction signature to a blockchain after requiring the seller to sign the puttermoney _ payback transaction;
8. to complete the seller's subsequent flow of the auction, the buyer signs the transaction deposint i and publishes it into the blockchain. The seller is then required to sign and issue a requests transaction. If the auction process is not complete, the seller will lose funds for output of locations, while the buyer loses funds for the location i transaction. The purchaser may redeem funds for deposint i (through the paydeposint transaction) through the getback deposing transaction. The buyer generates a secret s for receipt. And disclosing the h value in getback deposint with h ═ h(s);
9. the buyer signs put _ money i _ pay transaction after the buyer publishes and signs the requests on the seller, and the putestmoney _ payest is sent to the seller, and the seller publishes the put _ money i _ pay transaction to obtain funds;
10. if the goods are not satisfied and distributed, the buyer signs the goods; if not satisfied, entering the return process.
Example 4
A blockchain-based auction method, comprising the steps of:
a preparation link:
1. to qualify for participation in an auction, each of the participants who are required to participate in the auction submits an application for participation to the auctioneer, using the application transaction herein, and signing and releasing the application transaction to the front of the blockchain, requiring the seller s to sign a reply transaction; the use of the application transaction is to ensure that the buyer i has at least the funds vaSeller s according to vaAnd the seller's creditRatings (not discussed herein with respect to credit ratings) select a certain number of buyers to bid on and send them an informative confirmation, while signing with a block: t is trA refund transaction for recovering application transaction funds; since the buyer signs and distributes the application transaction after the seller signs the transaction of the reply, the buyer can certainly issue the application transaction at trAnd then withdraws funds for the application transaction. This step is to confirm that the buyer is in fact in possession of the funds; unlike the traditional form of deposit payment, the buyer does not worry about not being able to receive the deposit.
2. The seller creates an open _ max transaction for each buyer (k1 buyers) participating in the bidding for each lease, signs the transaction and publishes it into the blockchain for the english auction (i.e., open up auction); the fund of the transaction is
vmThe source is the seller, the transaction generates output that is input to the later open _ max _ paydispose, open _ max _ getback _ money transactions, the seller withdraws funds via the open _ max _ getback _ money transaction, and the bidding buyer is paid "deposit" via the open _ max _ pay _ dispose transaction; the purpose of these three transactions is to require the seller to post the results of the transaction within a specified time, max is a fixed amount only, and the final transaction prices are k max, k and v to prevent overly large funds from being at riskmThe value of (a) is given by the seller, which value is obtained by a seller function: (k, v)m) F1(c, va, n), where c is the credit of the buyer, n is the number of participants in the bid, va is the predicted bid price of the product, and the specific implementation of this function is not discussed, but k should be negatively related to va, vm should be positively related to c and va, and negatively related to n; the establishment of the credit system, the present invention, will not be discussed in detail.
For example, we can give the following formula:
k＝10(va<10000) (1)
k＝100(va>＝10000) (2)
vm＝va/(100*n)*c (3)
the output usage condition generated by the transaction is one of the following:
the seller has a signature and gives a max value in a certain format and the seller has a signature for the max value.
② signature of both seller and buyer
The seller signature open _ max _ paydeposing transaction is sent to the buyer, the source (input) of the transaction is the output generated by the open max transaction, and the recipients of the funds are k1 buyers, for the seller to pay the "deposit" to the buyer. Its usage meets the condition that the signature of both seller and buyer is carried on the deal with blkockt, at t1The time is later to take effect.
At time t1The internal seller can use the output generated by the open max transaction through the open _ max _ getback transaction to recover funds, and the open _ max _ payrelease transaction and the open _ max _ getback _ money transaction are only valid for transactions that take effect earlier, since digital currency such as bitcoin can prevent double payment.
If the seller is not at t1The output that was previously generated using the open max transaction then takes effect, resulting in lost funds for the seller.
open _ max _ getback _ money transaction funds recipient is the seller and the source is the output generated by open max.
Using a signature which meets the condition that the seller has the signature and gives a max value which meets a certain format and gives the signature of the seller to the max value; no funds are lost as long as the seller publishes max within the specified time.
3. Seller generates an hc＝H(sc) Sign open _ s transaction and publish it in blockchain, and sign transaction open _ s _ paydepots for each set of buyers (k 2) so that sellers are not publicly distributedcSo that a certain amount of money is lost, and the fund is vs，vsObtained from the following function:
vs＝F2(c，vb) (4)
where c is the credit value of the buyer, vbTo estimate the closing price; v. ofsShould be proportional to vbThe specific choice of function we do not discuss.
open _ s _ payresponses transaction input is the output generated by open _ s transaction, the use condition of open _ s _ payresponses transaction is the total signature of a group of buyers, and vsShould not be too large because the transaction functions to pay the deposit to total and reserveLattice peering; if the buyer violates the contract, the seller loses all vsThe winning buyer loses the transaction funds.
Similar to the open _ max transaction described above, the seller receives back the open _ s transaction through the open _ s _ getback _ moneys transaction to generate output funds, and pays for the deposit through the paydeposits transaction.
If the seller is not at t2The private publication s, open _ s _ payresponses transaction is in effect and the seller loses funds.
A bidding link:
4. buyers bid by issuing putmoney i transactions in the blockchain, and if the bid value is not max, the buyers can reclaim output generated by the transactions; but at this point the publish putmeney i transaction is not signed, requiring the seller to sign the putmeney i _ payload transaction, which is used to reclaim funds if t3The post seller does not follow up and publishes s, funds are reclaimed and the putmeney i transaction is signed and released into the blockchain after the seller signs the putmeney i _ payload transaction.
The putmoneyi transaction fund source is one of the buyers, and the use condition for generating output is one of the following two conditions:
that is, there is a buyer's signature and the value of max which requires the seller's signature
② there are two signatures and publish an s-make hc＝H(s)
The putmeney i _ Payback transaction is accompanied by a block, at t3Funds are then recovered by the seller, using the output generated by the putmoney i transaction, subject to the conditions:
② there are two signatures and publish an s-make hc＝H(s)
5. The seller signs the putmeney i _ payload transaction and issues it to the buyer, who signs and issues the putmeney i transaction into the blockchain.
6. Bidding completes the seller disclosure max and withdraws funds for the open _ max transaction by disclosing the open _ max _ getback _ money transaction and signing; the buyer recycles the output generated by the transaction putmeney i through the putmeney i _ giveback i transaction when the bid value is not max.
The transaction uses the output generated by the putmoney i transaction, and meets the use condition:
the buyer has a signature and the owned fund is not max, and the max value requires a seller to sign and pay:
7. the winning buyer's house generates a putestmoney transaction for payment of the remaining money and requests the seller to sign the putestmoney _ payback transaction before signing and releasing the transaction into the blockchain.
The source of the puttermoney transaction funds is a winning buyer, and the use conditions for generating output are as follows:
both parties sign and publish an s-let hc＝H(s)。
The purestmoney _ payback transaction receiver is a buyer, the input generates output for the purestmoney transaction according with the unique using condition, and the output is provided with block t4For withdrawing money when the seller is not making the next contract.
8.
