Based on the hardware structure of the equipment, the embodiment of the auction trading method based on the block chain is provided.
Referring to fig. 2, in a first embodiment of a blockchain-based auction transaction method of the present invention, the blockchain-based auction transaction method includes:
step S10, when the auction node of the target block chain receives the auction instruction, acquiring a work voucher and an auction account corresponding to the auction instruction.
The auction transaction method based on the block chain in this embodiment is applied to a target block chain, where the target block chain has a plurality of nodes (e.g., auction nodes in this embodiment) and a plurality of databases (e.g., a bill bank and a monitoring warehouse in this embodiment) capable of storing data, it can be understood that a user needing to auction works can register an auction account number, then log in the auction account number through the auction node, upload, to the target block chain, work certification information (i.e., a work certification in this embodiment) marked with the auction account number, when a manager of the target block chain receives an auction instruction triggered by the auction account number logging in the auction node and uploading the work certification information, the target block chain obtains the work certification and the auction account number corresponding to the auction instruction, and the manager of the target block chain can verify the work certification and the auction account number to ensure the accuracy of the auction account number, and the authenticity of the auction works, because the embodiment relates to the auction transaction industry, the authenticity of the auction works can be ensured only by verifying the auction works or manually verifying the auction works, the whole auction transaction process is realized by the target block chain and the manager of the target block chain together, the manager of the target block chain needs to execute the things which cannot be ensured by the target block chain, such as verifying the authenticity of the auction works, and the verification of the auction account number can be automatically completed by the target block chain.
Step S20, when the work voucher passes the verification, extracting a target bill from the bill library, establishing a first binding relationship between the auction account number and the target bill, and uploading the first binding relationship to the supervision bin.
When the auction account passes the verification of the voucher of the work uploaded by the auction node, one ticket (i.e., the target ticket in this embodiment) is extracted from the ticket library storing the tickets in the target block chain. The target bill in this embodiment has a unique code, so that the established first binding relationship between the auction account and the target bill is also unique in the target block chain, after the first binding relationship is established, the target bill carrying the information of the auction account is stored in the supervision bin in the target block chain to be managed in a unified manner until the auction activity of the auction works corresponding to the auction account starts, or the auction account withdraws the auction works, so that the target bill uploaded to the supervision bin is managed in a unified manner by the manager of the target block chain, and the manager of the target block chain can also use an encryption signature technology to digitally sign the target bill in the supervision bin to indicate that the works corresponding to the target bill are awaiting auction.
Step S30, when the transaction node of the target block chain receives the transaction instruction corresponding to the target ticket, determining whether the auction account corresponding to the transaction instruction is successful through the transaction intelligent contract in the target block chain.
The target block chain is also provided with transaction nodes, similar to the auction nodes, buyers wanting to auction works can register auction account numbers in advance, and then login the auction account numbers through the transaction nodes, and it can be understood that, when target bills carrying information of the auction account numbers are stored in the monitoring bin, information of the auction works corresponding to the auction account numbers is broadcast at the transaction nodes of the target block chain to prompt the buyers corresponding to the auction account numbers, after the buyers log in the auction account numbers through the transaction nodes, the information of the auction works and the corresponding auction time are checked, the buyers log in the auction account numbers to auction the auction works within the corresponding auction time, according to the existing auction rules, when the auction price output by a certain auction account number is larger than the market average price of the auction works, and no other auction account numbers are output within a period of time after the auction price is output by the auction account number, determining that the auction of the auction account is successful, writing the auction transaction rule into an intelligent contract in a programming language form to form a transaction intelligent contract in the target block chain of the embodiment, and judging the successful auction account by obtaining auction prices output by all auction accounts within the auction time corresponding to the auction works according to the transaction intelligent contract.
Step S40, if the auction of the auction account is successful, removing the first binding relationship from the supervision bin, establishing a second binding relationship between the auction account and the target bill, and uploading the second binding relationship to the supervision bin.
Defining the successful auction account for the auction works as a target auction account, determining the target auction account, and then removing the first binding relationship stored in the supervision bin, wherein the removal of the first binding relationship can be understood as deleting the auction account information originally carried by the target bill, or decrypting the digital signature on the target bill and deleting the digital signature by using the encryption technology to indicate that the work corresponding to the target bill has been auctioned, and then, after removing the first binding relationship, establishing a new binding relationship between the successful auction account and the target bill removed from the first binding relationship, that is, the second binding relationship in this embodiment, and then storing the target bill carrying the auction account information to the supervision bin in the target block chain for unified management.
Specifically, the step of step S20 refinement includes:
step a1, when the work voucher passes verification, extracting a no-signature bill from the bill library to obtain a preset elliptic curve and an operation rule corresponding to the preset elliptic curve.
Step a2, determining the private key based on the coordinate points on the preset elliptic curve and the operation rule.
Step a3, encrypting the auction account number by using the private key to obtain a first encrypted signature, and signing the unsigned ticket by using the first encrypted signature to obtain a target ticket, so as to establish a first binding relationship between the auction account number and the target ticket.
When the auction account passes the verification of the voucher of the work uploaded by the auction node, a bill is extracted from a bill library storing bills in a target block chain, the bills stored in the bill library are all defined to be unsigned bills, which is also a key for guaranteeing the one-to-one correspondence relationship between the auction account and the bills, when a user needs to auction a work each time, the user needs to register an auction account at the auction node, then the user extracts a unsigned bill with a unique code from the bill library after the verification of the work voucher (corresponding to only one work) uploaded by the registered auction account passes, at the moment, the auction account and the unique code of the bill establish a binding relationship, then the target block chain encrypts the auction account by using an inherent encryption algorithm to obtain a first encrypted signature, and then the unsigned bill is digitally signed by using the first encrypted signature, and obtaining the target bill so as to establish a first binding relationship between the auction account number and the target bill.
The encryption algorithm used by the target block chain is an elliptic curve encryption algorithm, which is essentially a pair of secret key pairs including a public key and a private key, and when the private key is known, the corresponding public key is easily obtained, and when the public key is known, the corresponding private key is difficult to obtain, specifically, assuming that the equation of an elliptic curve is: and y2 is x2+3x-5, an elliptic curve corresponding to the equation is drawn in a coordinate system, and the addition operation in the encryption algorithm is defined as follows: drawing a straight line through the point A and the point B on the elliptic curve, and finding out an intersection point G of the straight line and the elliptic curve, wherein the point of the point G at the symmetrical position of the point A and the point B relative to the x axis of the coordinate system is a point (A + B); defining the twofold operation in the encryption algorithm as: when the point A and the point B are superposed, defining the point where the point A and the point B are superposed as the point A, and defining a point at which a tangent of the elliptic curve at the point A is symmetrical to the x axis of the coordinate system and the intersection of the tangent and the elliptic curve as the point 2A; defining the positive and negative operations of the encryption algorithm as follows: when the point a and the point B coincide with each other, a point at which the point a and the point B coincide with each other is defined as a point a, and a point at which the point a is located symmetrically with respect to the x axis is defined as a point-a. Given a point (H point) and a coefficient 3 on the elliptic curve, it is very simple to calculate the coordinates of the 3H point, but conversely given the coordinates of the 3H point, it is very difficult to calculate the coordinates of the 3H point and the H point, so that an encryption algorithm with complicated decryption can be obtained simply by using the combination of the coordinates of the H point and the coefficient 3 as a private key and the coordinates of the 3H point as a public key.
Specifically, steps subsequent to step S20 include:
step b1, when the supervision cabin receives the management instruction corresponding to the target bill, acquiring the management duration corresponding to the management instruction.
And b2, determining management cost through the work voucher and the management duration, and locking the target bill in the supervision bin.
Step b3, in the management duration, if the supervision bin does not receive the withdrawal instruction corresponding to the management cost, unlocking the target ticket so that the trading node of the target block chain receives the trading instruction corresponding to the target ticket.
The user can also manage the held works, namely the user delivers the held works to the manager of the target block chain for management, when the monitoring bin receives a management instruction triggered by the auction account based on the target bill, the management duration corresponding to the management instruction is obtained, the target block chain determines the management cost according to the management duration and the value of the works, then the target bill is locked in the monitoring bin, within the management duration, if the manager of the target block chain does not receive a withdrawal instruction triggered by the auction account based on the target bill, that is, the monitoring warehouse does not receive the reclaiming instruction corresponding to the management cost, which indicates that the user corresponding to the auction account is unable to reclaim the works managed by the user, in this case, the target ticket locked in the monitoring bin will be unlocked, which indicates that the work corresponding to the target ticket will be auctioned, i.e. the trading node of the target blockchain can receive the trading instruction corresponding to the target ticket.
Specifically, the steps after step b2 include:
step c1, in the management duration, if the monitoring bin receives a recovery instruction corresponding to the management cost, the first binding relationship is released, and the first encrypted signature is erased.
And c2, if the target bill after the erasing processing is the unsigned bill, putting the target bill after the erasing processing into the bill storage.
Within the management duration, if a manager of the target block chain receives a withdrawal instruction triggered by the auction account based on the target ticket, namely, the supervision bin receives a recovery instruction corresponding to the management cost, which indicates that the user corresponding to the auction account starts a procedure for recovering the works, in this case, the target bill locked in the supervision bin will also be unlocked, the first binding relationship is then released, except that, after the first binding relationship is released, the first encrypted signature on the target ticket is erased, so that the target bill after the first encrypted signature is erased becomes a no-signature bill again, the target bill after the first encrypted signature is erased can also be put back into the bill library, it will be appreciated that a new unique code may also be provided for the ticket that is replaced in the ticket vault so that the ticket that is replaced in the ticket vault can be used as a new ticket.
Specifically, steps subsequent to step S20 include:
and d1, when the supervision bin receives a pledge instruction corresponding to the target bill, calculating pledge cost through a pledge intelligent contract in the target block chain, and locking the target bill in the supervision bin.
And d2, if the supervision bin does not receive the unlocking instruction corresponding to the pledge cost, unlocking the target bill so that the trading node of the target block chain receives the trading instruction corresponding to the target bill.
The user can also carry out the pledge on the held works, when the monitoring bin receives a pledge instruction triggered by the auction account based on the target bill, the pledge cost is calculated through pledge intelligent contracts in the target block chain, and can be understood that the pledge cost is related to the value of pledge works and pledge duration, and is generally calculated in a interest form, for example, if the market average price of pledge works is 10 ten thousand, the daily interest corresponding to pledge works is 0.04%, the calculation rules are written into the intelligent contracts in a programming language form, so that pledge intelligent contracts in the target block chain of the embodiment are formed, the pledge intelligent contracts calculate pledge cost by obtaining the value of pledge works and pledge duration, and when the monitoring bin receives the pledge instruction corresponding to the target bill, the target bill is locked in the monitoring bin until the monitoring bin receives an unlocking instruction triggered by the auction account based on the target bill, the method comprises the steps that a user corresponding to an auction account number starts a program for redeeming works of the user, under the condition, a target bill locked in a supervision bin is unlocked, then a first binding relationship is released, and the difference is that after the first binding relationship is released, a first encrypted signature on the target bill is erased, so that the target bill after the first encrypted signature is erased becomes a no-signature bill again, and the target bill after the first encrypted signature is erased is also placed in a bill bank; if the monitoring bin does not receive the unlocking instruction triggered by the auction account number based on the target bill after a certain time, in this case, the target bill locked in the monitoring bin will be unlocked, which indicates that the work corresponding to the target bill will be auctioned, i.e. the trading node of the target block chain can receive the trading instruction corresponding to the target bill.
In this embodiment, the auction transaction method based on the block chain is applied to a target block chain, the target block chain comprises a bill bank and a supervision bin, firstly, an auction node of the target block chain receives an auction instruction, obtains a work voucher and an auction account corresponding to the auction instruction, then verifies the work voucher, extracts the target bill from the bill bank when the work voucher passes verification, then establishes a first binding relationship between the auction account and the target bill, uploads the first binding relationship to the supervision bin of the target block chain, judges whether an auction account corresponding to the transaction instruction successfully auctions through a transaction intelligent contract in the target block chain when the transaction node of the target block chain receives a transaction instruction corresponding to the target bill, if the auction account succeeds in auctions, removes the first binding relationship from the supervision bin, and finally reestablishes a second binding relationship between the auction account successfully auctions and the target bill, and uploading the new second binding relationship to a supervision bin of a target block chain, linking up the auction transaction process of the works, ensuring the security of auction information through a bill bank and the supervision bin, ensuring the fairness of the auction transaction through an intelligent contract, combining the traditional auction transaction industry with the block chain technology, and breaking the limitation of the traditional auction transaction industry.

step S41, if the auction account is successful, the first binding relationship is released, and the first encrypted signature is erased to obtain a first bill.
Step S42, the private key is used for encrypting the auction account number to obtain a second encryption signature, and the second encryption signature is used for signing the first bill to obtain a second bill.
And step S43, establishing a second binding relationship between the auction account and the second bill, and uploading the second binding relationship to the supervision bin.
It can be known that, if the auction of the auction account is successful, the first binding relationship is released, the first encrypted signature is erased to obtain a first bill (a no-signature bill), then a private key is generated by using an encryption algorithm inherent to the target block chain, the auction account is encrypted by using the generated private key to obtain a second encrypted signature, and the first bill is signed by using the second encrypted signature to obtain a second bill, the second bill in this embodiment is different from the target bill in the above embodiment in signature, after the second bill is obtained, the second binding relationship between the auction account and the second bill is established, and the second binding relationship is uploaded to the supervision bin, it can be understood that, after the auction of the auction account is successful, the first binding relationship can also be released, then the bill from which the first encrypted signature is erased is placed back into the bill bin again, then a new unique code is set for the bill which is placed back into the bill bin again, and extracting a new no-signature bill from the bill library, and signing the new no-signature bill by using a second encryption signature to obtain a second bill.
Specifically, steps subsequent to step S40 include:
and e1, when the delivery instruction triggered by the auction account is received by the supervision cabin, acquiring the delivery information corresponding to the delivery instruction.
And e2, when the supervision bin receives a receiving instruction corresponding to the receiving information, removing the second binding relationship, erasing the second encrypted signature, and putting the second bill subjected to the erasing processing into the bill bank.
Therefore, a manager of the target block chain, after remittance is performed through the transaction node by the auction account, automatically triggers a delivery instruction based on the auction account, and the supervision bin acquires the receiving information corresponding to the delivery instruction after receiving the delivery instruction triggered by the auction account, wherein the receiving information includes a receiving address, a receiver and a contact mode, when the auction work is a virtual article, the receiving address can be a mailbox, when the buyer corresponding to the auction account receives the auction work, the buyer triggers the receiving instruction based on the auction account, and when the supervision bin receives the receiving instruction (corresponding to the receiving information) triggered by the auction account, the second binding relationship is released, the second encrypted signature is erased, and the erased second bill is put back to the bill base.
