Embodiments of the present invention will be described below with reference to the accompanying drawings.
Fig. 2 is a flowchart of an electronic bid supervision method based on a block chain according to an embodiment of the present invention. The embodiment of the invention provides an electronic bidding supervision method based on a block chain, aiming at the technical problems in the prior art, and the method comprises the following specific steps:
In this embodiment, the tenderer node may broadcast the tender information in the blockchain network, and optionally, the tenderer node may perform private key signature on the tender information by using its own private key, and broadcast the tender information after the private key signature in the blockchain network. After the bidder node in the blockchain network receives the bid inviting information, the bid inviting information can be broadcast in the blockchain network. Optionally, the bidding information includes an expiration time of a bid and an announcement period of the bidding information. That is, bidder nodes in the blockchain network need to broadcast their bid information before the expiration of the bid. Any participating node in the blockchain network may challenge the bid information broadcast by the bidder node during the bid information exposure period. That is, the bid information broadcast by the bidder nodes in the blockchain network may be spurious information to which other participating nodes are entitled to present a challenge during the exposure period.
In this embodiment, the bidder node a may be referred to as a first node, the bidder node B may be referred to as a second node, and the bidder node a and the bidder node B may broadcast bid information in the blockchain network, that is, the bidder node a may receive bid information broadcast by the bidder node B in the blockchain network, and the bidder node B may also receive bid information broadcast by the bidder node a in the blockchain network.
When the accounting node in the blockchain network receives the first record broadcasted by the bidder node a in the blockchain network, the first record is stored in the blockchain account book, and at this time, the corresponding amount ￥ a in the account of the bidder node a is automatically locked, that is, the amount ￥ a in the account of the bidder node a cannot perform other transactions.
After the bidder node B receives the first record broadcasted by the bidder node a in the blockchain network, the bidder node B may broadcast a second record in the blockchain network, where the second record includes relevant information of the challenged party and relevant information of the reverse challenged party, where the relevant information of the challenged party includes a blockchain identifier of the bidder node B, identification information of bid information broadcasted by the bidder node B in the blockchain network, and a reverse challenge identifier of the bidder node B for the bidder node a, where the identification information of the bid information of the bidder node B may include a bid number bid by the bidder node B and a bid file identifier.
When the accounting node in the blockchain network receives the second record broadcasted by the bidder node B in the blockchain network, the second record is stored in the blockchain account book, and at this time, the corresponding amount ￥ B in the account of the bidder node B is automatically locked, that is, the amount ￥ B in the account of the bidder node B cannot perform other transactions.
And 203, the caller node determines a winner node of the first node and the second node according to the first record and the second record.
After the bidder node receives the first record and the second record as described above, it may request both bidder node a and bidder node B offline to provide evidence and arbitrate. Optionally, before the end of the public period, the sponsor node signs the resolution result by using its own private key of the block chain, and broadcasts the resolution result signed by the private key to the network of the block chain. The adjudication result may include the bidder node a determined by the bidder node and a winner node in the bidder node B, and the winner node is assumed to be the bidder node a.
After receiving the decision result broadcasted by the bidder node, the billing node in the blockchain network may verify the private key signature of the bidder node, and after the verification passes, according to the decision result, release the guaranteed amount ￥ a of the winner node, i.e., the bidder node a, and allocate the guaranteed amount ￥ B of the loser node, i.e., the bidder node B, to the bidder node a and other nodes in the blockchain network according to a preset proportion.
It is to be understood that bidder nodes in the blockchain network are not limited to bidder node a and bidder node B. For example, bidder node C may also be included.
After the public period is finished, the bid issuer node can evaluate the bid information of the bidder node a and the bidder node C according to a preset bid-winning rule, determine the bid-winning party node in the bidder node a and the bidder node C, generate a bid-winning result, and broadcast the bid-winning result in the block chain network. For example, the winning bidder node is bidder node a, and bidder node a and the publisher node subsequently sign the intelligent contract and execute the intelligent contract. That is, when the tenderer node determines that the bidder node B is a loser node, that is, the bidding information broadcast by the tenderer node B is the false information, the tenderer node may delete the bidding qualification of the tenderer node B.
According to the embodiment of the invention, the first node in the block chain network is used for questioning the bid information of the second node, and the second node is used for reversely questioning the first node, so that the sponsor node can determine the winner node or the loser node according to the question of the first node on the bid information of the second node and the reverse question of the second node on the first node, and therefore, the billing node in the block chain network can release the guarantee amount of the winner node, and the guarantee amount of the loser node is distributed to the winner node and other nodes, so that the sponsor node supervises the bid information, false bid information is prevented from being broadcast to the block chain network, and the safety of an electronic bidding system is improved.
Fig. 3 is a flowchart of an electronic bid management method based on a block chain according to another embodiment of the present invention. On the basis of the foregoing embodiment, the block chain-based electronic bid supervision method provided in this embodiment specifically includes the following steps:
For example, when broadcasting a first record in the blockchain network, the bidder node a may first sign the first record using its own blockchain private key, and further broadcast the first record signed by the private key in the blockchain network. Correspondingly, the tenderer node receives a first record signed by a private key broadcasted by the bidder node A in the blockchain network.
For example, when the bidder node B broadcasts the second record in the blockchain network, the second record may be signed by using its own blockchain private key, and further, the second record signed by the private key may be broadcast in the blockchain network. Correspondingly, the tenderer node receives a second record signed by a private key broadcast by the bidder node B in the blockchain network.
And step 303, the publisher node verifies the private key signature of the first node and the private key signature of the second node.
After the tenderer node receives the first record signed by the private key of the bidder node A and the second record signed by the private key of the bidder node B, the private key signature of the bidder node A and the private key signature of the bidder node B are verified.
And step 304, after the private key signature of the first node and the private key signature of the second node are verified by the publisher node, determining a winner node in the first node and the second node according to the first record and the second record.
And when the private key signature of the bidder node A and the private key signature of the bidder node B pass the verification, determining a winner node or a loser node in the bidder node A and the bidder node B according to the first record signed by the private key of the bidder node A and the second record signed by the private key of the bidder node B.
In some embodiments, if the bidder node has not made a sanction for the exposure period, i.e., the bidder node has not broadcast the sanction result in the blockchain network for the exposure period, other nodes in the blockchain network, e.g., a billing node, may automatically charge a certain service fee for bidder node a and bidder node B and release the guaranteed amount for bidder node a and bidder node B.
According to the embodiment of the invention, the first node in the block chain network is used for questioning the bid information of the second node, and the second node is used for reversely questioning the first node, so that the sponsor node can determine the winner node or the loser node according to the question of the first node on the bid information of the second node and the reverse question of the second node on the first node, and therefore, the billing node in the block chain network can release the guarantee amount of the winner node, and the guarantee amount of the loser node is distributed to the winner node and other nodes, so that the sponsor node supervises the bid information, false bid information is prevented from being broadcast to the block chain network, and the safety of an electronic bidding system is improved.
