Detailed Description
In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.
It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
First, a block chain network according to the present disclosure will be explained:
the blockchain network to which the present disclosure relates may be a public chain, a private chain, or a federation chain, among others. The blockchain network to which the present disclosure relates may include a plurality of blockchain nodes, each of which may be located in the same or different devices.
The block link points in the block chain network may include: a transaction node, the transaction node being a node that performs transactions over a blockchain network, the transaction node comprising: bidding nodes and bidding nodes. The bidding node is a seller node and the bidding node is a buyer node of the blockchain transaction. It will be appreciated that the same trading node may be a bidding node in one blockchain transaction and a bidding node in another blockchain transaction.
When block chain transaction is carried out, transaction information can be sent out by both the auction nodes and the bidding nodes, wherein the transaction information sent out by the auction nodes can comprise: information of the transaction object, node information of the auction node, seller offer information of the auction node, and the like. The transaction object is an object of blockchain transaction, such as: when the auction node wants to sell a non-physical object, the virtual object is the transaction object. The non-physical object may be: futures.
Accounting nodes are nodes with block accounting rights for blockchain transactions, such as: when a certain bidding node and a certain bidding node reach a certain block chain transaction, the bidding node is a billing node, and the bidding node has the block billing right of the block chain transaction reached at this time.
The transaction information sent by the bidding node may include: information of the transaction object, node information of the bidding node, bid information of the buyer of the bidding node, bid time of the bidding node, and the like.
The node information may be a node identifier.
Optionally, the transaction information sent by the bidding node and the bidding node may also carry a private key signature.
When the blockchain transaction is carried out, a transaction request can be sent out by the auction node, and the transaction request can be transaction information sent out by the auction node.
In an optional embodiment of the present disclosure, the blockchain network may include other nodes besides the transaction node, such as: at least one of a normal node, a supervisory node and an operational node.
The common node is only used as a node for synchronizing the account book, and the common node can perform distributed recording and evidence saving on various received information.
The operator node may be a node of a transaction operator of the blockchain. The operation node may perform validity verification on the transaction request (e.g., verify ownership of the transaction object by the bidding node, verify a private key signature in the transaction request, etc.), and if the transaction request is truly valid, may issue a bidding notification to each transaction node, where the bidding notification carries a timestamp of a bidding start time, a bidding requirement, etc. After receiving the bid-buying information of each bidding node, the operation node verifies the validity of the bid-buying information of each bidding node (for example, verifies whether a certain bidding node has so much money), if not, the operation node sends the result of the non-validity to all block chain nodes, and if the operation node is legal, the operation node sends the result of the validity to all the nodes. A transaction operator of a blockchain may set bidding requirements for blockchain transactions. Specifically, the same or different bidding requirements may be set for each transaction object. The bidding starting time is the starting time of sending the buyer bidding information by each bidding node. By the bidding starting time, the fairness of each bidding node on the bidding time can be ensured. Of course, although the bidding start time received by each bidding node is the same, the time of the bidding information issued by each bidding node may be the same or different.
The supervision node may be a supervision node of a supervision entity of the blockchain transaction, and the supervision node may obtain various information involved in the blockchain transaction, but does not participate in the transaction process.
Optionally, as shown in fig. 1, the system architecture of the blockchain network of the present disclosure may be divided into three layers: the system comprises a block chain layer 001, a middleware layer 002 and a transaction system layer 003, wherein the block chain layer 001 is a bottom layer, the transaction system layer 003 is an upper layer, and the middleware layer 002 is arranged between the block chain layer 001 and the transaction system layer 003. Specifically, there may be multiple transaction system layers 003 of the blockchain network of the present disclosure, such as: a futures trading system layer of the product A, a futures trading system layer of the product B, a real-time trading system layer of the product C and the like. Each transaction system layer 003 can communicate with the same blockchain layer 001 through the same or different middleware layer 002.
The following describes a method for determining block chain accounting right provided by an embodiment of the present disclosure:
the method for determining the block chain accounting right provided by the embodiment of the disclosure is applied to a voting node in a block chain network, and the block chain network at least comprises: a plurality of transaction nodes, wherein the voting nodes are at least part of nodes in a blockchain network, as shown in fig. 2, the method for determining the block accounting right may include:
s100, the voting node obtains seller offer information sent by an auction node of the target block chain transaction, wherein the auction node is a seller node in the transaction node related to the target block chain transaction.
Optionally, the seller bid information may include at least a selling price.
Optionally, some or all of the nodes in the blockchain network may be voting nodes. If all the nodes except the supervision node are used as voting nodes, then: all transaction nodes associated with the target blockchain transaction act as voting nodes. The voting nodes are nodes with voting authority. Each voting node can vote on its determined bidding node to vote for a billing node.
Alternatively, the voting node may be a transaction node.
Optionally, each voting node may perform steps S100 to S300, and each voting node votes for the determined bidding node, and determines a billing node having a block billing right for the target block chain transaction according to the voting result.
Optionally, the voting node may further obtain information of a transaction object sent by the auction node, node information of the auction node, and the like.
Optionally, the seller offer information may further include: time to bid effective, etc. Since the seller cannot wait for the bid of the buyer permanently, it is possible to avoid a long wait by setting the effective time of the bid.
S200, the voting node obtains the buyer offer information sent by the bidding nodes of the target block chain transaction, wherein the bidding nodes are buyer nodes in the transaction nodes related to the target block chain transaction.
Optionally, the bid-for-buyer information at least includes: the purchase basic price and the purchase floating price, and optionally, the bid-offer information may further include: the time of the bid.
It will be appreciated that in some cases not all of the trading nodes will bid on a targeted blockchain transaction, and thus the trading node that issues the buyer bid information may be referred to as a bidding node for the targeted blockchain transaction.
Alternatively, the bid base price is a base price given by the bidding node, and the bids of the bidding node may be a range of bid prices determined from the bid base price and the bid float price. Wherein, the purchase float price can be: floating up price, floating down price or floating up and down price. For ease of understanding, the following is exemplified:
example 1: if the purchase basic price is 5 and the purchase floating price is-1, the purchase floating price is a downward floating price, and the determined purchase price range is as follows according to the purchase basic price and the purchase floating price: 4 to 5.
Example 2: if the purchase basic price is 5 and the purchase floating price is +1, the purchase floating price is a floating price, and the determined purchase price range is as follows according to the purchase basic price and the purchase floating price: 5 to 6.
Example 3: if the purchase basic price is 5 and the purchase floating price is +/-1, the purchase floating price is up-down floating price, and the determined purchase price range is as follows according to the purchase basic price and the purchase floating price: 4 to 6.
Optionally, each bidding node may start to bid according to the bidding starting time of the unified time service center.
S300, the voting nodes determine the bidding nodes to be voted by the voting nodes according to the bidding information of the sellers and the bidding information of the buyers sent by the bidding nodes.
Alternatively, each voting node can determine the bidding node to vote based on the bids of the buyer and the seller and the bidding time of the bidding node. Alternatively, the bidding nodes to be voted determined by each voting node may be the same or different.
In other embodiments of the present disclosure, the seller offer information at least includes a selling price, and the buyer offer information at least includes: the basic price of buying and the floating price of buying, each voting node can determine the bidding node to be voted according to the process shown in fig. 3, namely: step S300 in the method shown in fig. 2 may specifically include:
s310, the voting nodes respectively determine the buying price range of each bidding node according to the buying basic price and the buying floating price in the buying bid information sent by each bidding node.
Step S310 determines that the purchase price range is described in text below step S200, and will not be described in detail.
S320, determining an initial enclosing node from the bidding nodes by the voting node, wherein the buying price range of the initial enclosing node comprises a selling price.
Still by way of example 3, below, when the determined bid price range is: 4 to 6, if the selling price in the seller offer information sent by the bidding node is 5.8, then the bidding price range includes the selling price, and the bidding node giving the bidding price range can be determined as the initial enclosing node.
S330, determining the bidding nodes to be voted by the voting nodes from the initial enclosing nodes by the voting nodes according to the basic buying price of the initial enclosing nodes.
The bidding basic price is the basic bid of the bidding nodes, so that the bidding nodes are relatively important, and when a plurality of initial entry nodes exist, the bidding nodes to be voted by the voting nodes can be determined from the initial entry nodes according to the closeness degree of the bidding basic price and the selling price.
When the bid time is further included in the bid information of the buyer, as shown in fig. 4, step S330 may specifically include:
and S331, determining the size relation between the number of the initial enclosing nodes and 1 by the voting nodes, executing the step S332 when the number of the initial enclosing nodes is equal to 1, executing the step S333 when the number of the initial enclosing nodes is greater than 1, and executing the step S334 when the number of the initial enclosing nodes is less than 1.
When the number of the initial entry nodes is less than 1, the number of the initial entry nodes is 0.
S332, the voting node determines the initial enclosing node as a bidding node to be voted by the voting node.
And S333, determining the initial entry node with the purchase basic price closest to the selling price as a secondary entry node by the voting node, and determining the bidding node to be voted by the voting node from the secondary entry nodes by the voting node according to the bidding time of the secondary entry nodes.
Optionally, step S333 may specifically include:
when the number of the secondary entry nodes is 1, the voting nodes determine the secondary entry nodes as the bidding nodes to be voted by the voting nodes;
when the number of the reentrant nodes is larger than 1, the voting node determines the reentrant node with the earliest bidding time as the bidding node to be voted by the voting node.
And S334, the voting node determines that the target blockchain transaction fails.
Upon determining that the target blockchain transaction failed, a message that the target blockchain transaction failed may be sent to other blockchain nodes.
Optionally, in other embodiments of the present disclosure, the voting node or the operation node may also perform auditing on the purchase basic price and the purchase floating price. Specifically, a proportional relationship between the purchase base price and the purchase float price may be determined, and when a ratio between the purchase float price and the purchase base price exceeds a preset value, it is determined that the bid/offer information including the purchase base price and the purchase float price is invalid. By limiting the preset value, the bidding nodes can be prevented from giving a particularly large buying price range. For example: if the purchase basic price is 5 and the purchase floating price is +/-100, determining the purchase price range according to the purchase basic price and the purchase floating price as follows: -95 to 105.
Upon determining that the bid-buyer information for a bidding node is invalid, a message can be sent to other blockchain nodes and recorded into the blockchain that the bid-buyer information for that bidding node is invalid.
S400, each voting node votes for the determined bidding node, and at least one bidding node is determined as follows according to the voting result: accounting node with block accounting rights for the target blockchain transaction.
Optionally, when the voting result of each voting node indicates that the voting node exceeding the preset proportion votes for the first bidding node, the first bidding node may be determined as a billing node having the block billing right of the target block chain transaction. Wherein the predetermined proportion is higher than 50%.
