Detailed Description
In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of 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 foregoing figures are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The implementations described in the following exemplary examples are not representative of all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.
First, a blockchain network to which the present disclosure relates will be described:
the blockchain network to which the present disclosure relates may be a public chain, a private chain, a federated chain, or the like. 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 blockchain nodes in the blockchain 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 the seller node of the blockchain transaction and the bidding node is the buyer node of the blockchain transaction. It will be appreciated that the same transaction node may bid for a node in one blockchain transaction and may be a bidding node in another blockchain transaction.
When conducting a blockchain transaction, both the bidding node and the bidding node may send out transaction information, where the transaction information sent by the bidding node may include: information of transaction objects, node information of the auction node, vendor bid information of the auction node, and the like. Wherein, the transaction object is the object of blockchain transaction, such as: when the auction node wants to sell a certain non-physical object, the virtual object is the transaction object. The non-physical object may be: futures.
The transaction information sent by the bidding node may include: information of transaction objects, node information of bidding nodes, bid information of the bidding nodes, bid time of the bidding nodes and the like.
The node information may be a node identifier.
Optionally, the transaction information sent by the bidding node and the bidding node can also carry private key signatures.
In conducting a blockchain transaction, a transaction request may be issued by the auction node, which may be the transaction information issued by the auction node.
In an alternative embodiment of the present disclosure, other nodes may be included in the blockchain network in addition to the transaction node, such as: at least one of a common node, a supervision node and an operation node.
The common node is a node which is only used as a synchronous account book, and the common node can perform distributed record and verification on various received information.
The operating 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. verifying ownership of the transaction object by the auction node, verifying a private key signature in the transaction request, etc.), if it is truly legal, then may issue a bid notification to each transaction node, where the bid notification carries a timestamp of a time when the bid starts, a bid requirement, etc. After the operation node receives the bid information of each bidding node, the operation node performs validity verification on the bid information of each bidding node (for example, verifying whether a bidding node has so much money), if not, the operation node sends the illegal result to all the blockchain nodes, if so, and sends the legal result to all the nodes. The transaction operator of the blockchain may set bid requirements for the blockchain transaction. Specifically, the same or different bid requirements may be set for each transaction object. The bid start time is a start time when each bidding node transmits bid information. By the bidding starting time, fairness of each bidding node at the bidding time can be ensured. Of course, although the bid start times received by the respective bidding nodes are the same, the times of the bid information issued by the respective bidding nodes may be the same or different.
The supervisory node may be a supervisory node of a supervisory entity of a blockchain transaction that may obtain various information involved in the blockchain transaction, but not participate in the transaction process.
Alternatively, 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 blockchain layer 001, a middleware layer 002 and a transaction system layer 003, wherein the blockchain layer 001 is a bottom layer, the transaction system layer 003 is an upper layer, and the middle of the blockchain layer 001 and the transaction system layer 003 is the middleware layer 002. Specifically, the transaction system layer 003 of the blockchain network of the present disclosure may have a plurality of transaction systems, such as: a product futures trading system layer, a product real-time trading system layer and the like. Each transaction system layer 003 may communicate with the same blockchain layer 001 through the same or different middleware layer 002.
The following describes a transaction information storage method provided by an embodiment of the present disclosure:
as shown in fig. 2, a transaction information saving method provided in an embodiment of the present disclosure includes:
s110, determining at least one similar blockchain transaction of the target blockchain transaction from the completed historical blockchain transaction according to the information proximity degree of at least one transaction information of the target blockchain transaction and corresponding transaction information of the completed historical blockchain transaction by the accounting node, wherein the accounting node is a blockchain node with the blockaccount right of the target blockchain transaction.
Optionally, the billing node determining transaction information used by the similar blockchain transaction may include:
at least one of transaction object, transaction time, and transaction price.
Wherein, the transaction object is the object of the transaction of the buyer and the seller, such as: the bidding node A sells out an article, the bidding node B obtains ownership of the article through bidding, the article is the transaction object, and the bidding node B is the billing node with the block billing right of the target block chain transaction.
The transaction time may be the determined moment of determining the billing node, as in the example above, the moment of determining the bidding node B as the billing node is the transaction time.
The proximity of the transaction object can be divided into: the transaction objects are the same, the transaction objects are different but of the same type, the transaction objects are of different types, etc. For example: if the transaction object of the target blockchain transaction is a light fuel futures of a three-month contract, if the transaction object of the completed historical blockchain transaction is also a light fuel futures of a three-month contract, the transaction objects are the same, if the transaction object of the completed historical blockchain transaction is a light fuel futures of a six-month contract, the transaction objects are different but belong to the same type (light fuel futures), if the transaction object of the completed historical blockchain transaction is a heavy fuel futures of a six-month contract, the transaction objects are of different types (one belongs to the light fuel futures, and one belongs to the heavy fuel futures).
Wherein the proximity of the transaction time may be determined according to a time interval of the transaction time of the target blockchain transaction and the transaction time of the historical blockchain transaction, for example: and ordering the completed historical blockchain transactions according to the sequence from small to large in time interval, and determining the N completed historical blockchain transactions before ordering as the historical blockchain transactions with close transaction time. And the following steps: and determining the historical blockchain transactions with the time intervals lower than the preset duration as the historical blockchain transactions with the close transaction time.
Wherein the proximity of the transaction price may be determined based on an absolute value of a difference between the transaction price of the target blockchain transaction and the transaction price of the historical blockchain transaction, such as: and ordering the completed historical blockchain transactions according to the order of the absolute value from small to large, and determining the N completed historical blockchain transactions before ordering as the historical blockchain transactions with close transaction prices. And the following steps: and determining the historical blockchain transaction with the absolute value lower than the preset threshold value as the historical blockchain transaction with the close transaction price.
The present disclosure may determine historical blockchain transactions that are identical in transaction objects and close in transaction time and close in transaction price as similar blockchain transactions.
The present disclosure may also determine historical blockchain transactions that are different in transaction objects but of the same type and close in transaction time and close in transaction price as similar blockchain transactions.
Alternatively, over time, historical blockchain transactions are increasing, but not all historical blockchain transactions are completed transactions. Some historic blockchain transactions are not committed, and the historic blockchain transactions are incomplete historic blockchain transactions.
Alternatively, transaction information for historical blockchain transactions may be recorded into the block, whether completed or not.
Optionally, the billing node determines at least one similar blockchain transaction of the target blockchain transaction from the completed historical blockchain transactions based on the information proximity of the at least one transaction information of the target blockchain transaction and the corresponding transaction information of the completed historical blockchain transaction, comprising:
the accounting node determines the completed historical blockchain transactions that satisfy the transaction object condition, the transaction time condition, and the transaction price condition simultaneously as similar blockchain transactions to the target blockchain transaction,
wherein, the transaction object conditions are: the transaction object is the same as the transaction object of the target blockchain transaction;
The trade time conditions are: the proximity of the transaction time with the target blockchain transaction meets a first preset proximity;
the trade price conditions are: the proximity of the transaction price to the target blockchain transaction satisfies a second preset proximity.
Optionally, the first preset proximity may be: the time interval between the transaction time of the target blockchain transaction and the transaction time of the historical blockchain transaction is less than the preset duration.
Optionally, the first preset proximity may be: and sequencing each completed historical blockchain transaction according to the sequence from small to large in time interval, wherein the sequencing is within the first N.
Optionally, the second preset proximity may be: the absolute value of the difference between the transaction price of the target blockchain transaction and the transaction price of the historical blockchain transaction is below a preset threshold.
Optionally, the second preset proximity may be: and sequencing the completed historical blockchain transactions from the small absolute value to the large absolute value to within the first N.
S120, the accounting node obtains transaction information of similar blockchain transactions.
Alternatively, the billing node may obtain transaction information for similar blockchain transactions from the block.
S130, the accounting node records at least part of transaction information of the similar blockchain transaction into a target block, wherein the target block is a block for at least storing the transaction information of the target blockchain transaction, and the at least part of transaction information of the similar blockchain transaction is marked as reference information of the target blockchain transaction in the target block.
Optionally, each tile may be used to hold transaction information for a target blockchain transaction and reference information for the target blockchain transaction.
Optionally, the block may store a field "reference information", where the specific content corresponding to the field may be at least part of transaction information of a similar blockchain transaction. In this way, the present disclosure marks at least a portion of the transaction information of the similar blockchain transaction as reference information of the target blockchain transaction in the target block.
Optionally, the transaction information of the similar blockchain transaction recorded into the target block may include:
at least one of node information of the bidding node, bid information of the bidding node, node information of the bidding node, and bid information of the seller of the bidding node, wherein the bid information at least comprises: the bid base price, the bid floating price, and the bid time, the seller bid information including at least the sell price.
Alternatively, the bid base price is the base price offered by the bidding node, and the bid price of the bidding node may be a range of bid prices determined based on the bid base price and the bid floating price. Wherein, the buying floating price can be: floating up price, floating down price, or floating up and down price.
Optionally, the method shown in fig. 2 may further include:
the billing node records at least a portion of the transaction information for the target blockchain transaction into the target block.
Optionally, the method shown in fig. 2 may further include:
and the billing node records a first hash value into the target block, wherein the first hash value is a hash value of transaction information of the similar blockchain transaction.
By recording the hash value into the block, the transaction information can be checked according to the hash value, so that the validity of the transaction information is ensured.
The transaction information of the completed historical blockchain transaction is recorded in the historical block.
In the transaction information storage method provided by the disclosure, according to the information proximity degree of at least one transaction information of a target blockchain transaction and corresponding transaction information of a completed historical blockchain transaction, determining at least one similar blockchain transaction of the target blockchain transaction from the completed historical blockchain transaction, wherein the accounting node is a blockchain node with the blockchain accounting right of the target blockchain transaction, and the accounting node obtains the transaction information of the similar blockchain transaction; the billing node records at least a portion of the transaction information for the similar blockchain transaction into a target block, the target block being a block for holding at least the transaction information for the target blockchain transaction, the at least a portion of the transaction information for the similar blockchain transaction being marked in the target block as reference information for the target blockchain transaction. The accounting node of the present disclosure may record at least a portion of transaction information of a similar blockchain transaction into a block, so that whether the target blockchain transaction is legal or not may be determined by comparing the transaction information of the target blockchain transaction with the transaction information of the similar blockchain transaction, thereby improving the regulatory effectiveness of the blockchain transaction.
In other embodiments of the present disclosure, the billing node having the blockcount of the target blockchain transaction may be determined from the bidding nodes of the target blockchain transaction through the steps shown in fig. 3. Fig. 3 provides a method for determining block accounting rights.
As shown in fig. 3, a method for determining a block accounting right provided in the present disclosure may include:
s210, the voting node obtains the seller bid information sent by the auction node of the target blockchain transaction, wherein the auction node is a seller node in the transaction nodes related to the target blockchain transaction.
Optionally, the seller bid information includes at least a sell price.
The steps shown in fig. 3 may be performed by a voting node in a blockchain network that includes at least: the plurality of transaction nodes, the voting node being at least a portion of nodes in the blockchain network.
Alternatively, some or all of the nodes in the blockchain network may be voting nodes. If all nodes except the supervision node are used as voting nodes, the following steps are: all transaction nodes associated with the target blockchain transaction act as voting nodes. The voting node is a node with voting rights. Each voting node may vote on its determined bidding node to vote on the determination of the billing node.
Alternatively, the voting node may be a transaction node.
Alternatively, each voting node may perform steps S210 to S230, respectively, and then each voting node votes on its determined bidding node, and determines the billing node having the block billing right for the target blockchain transaction based on the voting result.
Optionally, the voting node may also obtain information about the transaction object sent by the auction node, node information of the auction node, and the like.
Optionally, the vendor bid information may further include: bid validity time, etc. Since the seller cannot wait for the buyer's bid permanently, long waiting times can be avoided by setting the bid validity time.
S220, the voting node obtains the bid information of the buyer sent by the bidding node of the target blockchain transaction, wherein the bidding node is the buyer node in the transaction nodes related to the target blockchain transaction.
Optionally, the bid information includes at least: the bid base price and bid floating price, optionally, the bid information may further include: bidding time.
It will be appreciated that in some cases, not all of the transactional nodes will bid on the target blockchain transaction, and thus the transactional node that issued the bid information may be referred to as the bidding node for the target blockchain transaction.
Alternatively, the bid base price is the base price offered by the bidding node, and the bid price of the bidding node may be a range of bid prices determined based on the bid base price and the bid floating price. Wherein, the buying floating price can be: floating up price, floating down price, or floating up and down price. For ease of understanding, the following is illustrative:
example 1: if the buying basic price is 5 and the buying floating price is-1, the buying floating price is the floating price, and the determined buying price range is as follows according to the buying basic price and the buying floating price: 4 to 5.
Example 2: if the buying basic price is 5 and the buying floating price is +1, the buying floating price is the floating price, and the determined buying price range is as follows according to the buying basic price and the buying floating price: 5 to 6.
Example 3: if the buying basic price is 5 and the buying floating price is +/-1, the buying floating price is up and down floating price, and the determined buying price range is as follows according to the buying basic price and the buying floating price: 4 to 6.
Alternatively, each bidding node may start bidding according to the bidding start time of the unified time service center.
And S230, determining the bidding node to be voted by the voting node according to the seller bidding information and the buyer bidding information sent by each bidding node by the voting node.
Alternatively, each voting node may determine the bidding node to vote on based on the bids of the buyers and sellers 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 bid information includes at least a sell price, and the buyer bid information includes at least: the base price for the purchase and the floating price for the purchase, each voting node may determine an accounting node according to the procedure shown in fig. 4, respectively, namely: step S230 in the method shown in fig. 3 may specifically include:
s231, the voting node respectively determines 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 S231 determines that the buying price range has been described in text below step S220, and will not be described again.
S232, the voting node determines an initial enclosing node from the bidding nodes, wherein the buying price range of the initial enclosing node comprises the selling price.
Still by way of example 3, when the determined purchase price range is: 4 to 6, if the bid price in the bid information of the seller issued by the auction node is 5.8, the bid price range includes the bid price, the auction node giving the bid price range may be determined as the initial in-range node.
S233, determining bidding nodes to be voted by the voting nodes from the initial enclosing nodes according to the buying basic price of the initial enclosing nodes by the voting nodes.
Since the basic price is the basic bid of the bidding node, it is relatively important that when there are a plurality of initial enclosing nodes, the bidding node to be voted by the voting node can be determined from the initial enclosing nodes according to the proximity of the basic price to the selling price.
In the case that the bid information further includes a bid time, step S233 may specifically include:
the voting node determines the size relation between the number of initial enclosing nodes and 1, when the number of the initial enclosing nodes is equal to 1, the voting node determines the initial enclosing nodes as bidding nodes to be voted by the voting nodes, when the number of the initial enclosing nodes is greater than 1, the voting node determines the initial enclosing nodes with the closest buying base price to the selling price as re-enclosing nodes, the voting node determines the bidding nodes to be voted by the voting nodes from the re-enclosing nodes according to the bidding time of the re-enclosing nodes, and when the number of the initial enclosing nodes is less than 1, the voting node determines that the target block chain transaction fails.
When the number of the initial enclosing nodes is smaller than 1, the number of the initial enclosing nodes is 0.
Optionally, the voting node determines an initial enclosing node with the buying base price closest to the selling price as a enclosing node again, and the voting node determines, according to the bidding time of each enclosing node again, bidding nodes to be voted by the voting node from the enclosing nodes again, which may specifically include:
when the number of the re-enclosing nodes is 1, the voting node determines the re-enclosing nodes as bidding nodes to be voted by the voting nodes;
when the number of re-enclosing nodes is larger than 1, the voting node determines the re-enclosing node with the earliest bid time as the bidding node to be voted by the voting node.
After determining that the target blockchain transaction fails, a message of the target blockchain transaction failure may be sent to other blockchain nodes.
Optionally, in other embodiments of the present disclosure, the voting node or the operation node may also audit the base price of the purchase, the floating price of the purchase. Specifically, the ratio of the base price to the floating price can be determined, and when the ratio of the floating price to the base price exceeds a preset value, the bid information including the base price and the floating price is determined to be invalid. By limiting the preset value, the bidding node can be prevented from giving a particularly large range of bid prices. For example: assuming that the buying base price is 5 and the buying floating price is +/-100, determining the buying price range according to the buying base price and the buying floating price: -95 to 105.
