Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Before describing the scheme provided by the embodiment of the present invention, the technical nouns related to the embodiment of the present invention are first described:
1. blockchain: a technology based on a distributed account book and a consensus mechanism, wherein the distributed account book is used for sharing information among all nodes, and the consensus mechanism is used for confirming and issuing information changes which occur to the distributed account book by the nodes, and the information changes which occur on all nodes of a blockchain have non-tamper property and traceability.
2. Intelligent contract: conventional contracts, the contracts may be subject to a number of problems to be executed. And executing failure problems and third party participation problems. Even further problems may be encountered during execution of the contract.
Smart contracts are a set of digitally defined commitments that include agreements on which contract participants can perform. That is, smart contracts are a set of protocols that automatically perform certain manual tasks. In essence, intelligent contracts correspond to the construction of a contract in a computer system that is readable by all parties. Only when a certain event is triggered, the execution is performed immediately. For example, A pays B for XX, and B gives A the goods.
The smart contracts do not have to be implemented in dependence on the blockchain, but part of the underlying nature of the blockchain determines that the smart contracts are more suitable for implementation on the blockchain. Such as decentralization, tamper resistance of data, high availability, etc. The decentralization can ensure that the whole network backup of the data is not interfered by a third party mechanism, and the data can be tampered without worrying about. Meanwhile, the method is also beneficial to the subsequent audit work. High availability does not present problems such as attacks or other problems with current central services or central storage systems where contracts do not execute. In summary, the best characteristic that blockchains give smart contracts is the "trust mechanism".
Asset transactions on blockchains are an important research direction for blockchain applications. For a long time, two development routes of decentralization transaction and centralization transaction exist in the transaction.
At the present time, centralized transactions are the mainstay of blockchain asset transactions. Whether blockchain digital currency transactions are primarily completed by centralized transactions, various blockchain-based digital asset transactions are also centrally completed, which often require customers to host digital assets to a designated account. The clients submit the trade report to the trade center, the trade is matched by the trade center, and the settlement is transferred. The centralized transaction of the digital asset is not greatly different from the centralized transaction of the traditional asset, and the defects of the traditional centralized transaction such as high system requirements, high credit risk and the like exist, and the technical faults of the exchange lead to the infinite layers of customer loss, the theft of the asset hosted by the exchange, the rolling and running of the exchange and the like.
The decentralization transaction is also more realized on the blockchain, but the current decentralization exchange often has no asset pricing function, and the main function is to provide transactions for transacted intent players. The main transaction protocols of the decentralised exchange include 0x,IDEX,Waves,Loopring,Kyber Network,Decred,Nash exchange and atom dex etc. Wherein 0x relies on a repeater (relay) model to conduct the process of matching orders between two traders. IDEX only supports ethernet ecology tokens, using ethernet as a settlement layer, all content is first updated in its centralized database before it is written into the blockchain. The Waves DEX is deduced from the Waves item. The Waves have their own blockchain and a token (Waves) of the same name, which is part of their decentralized transaction platform. While the Waves order matching engine is open source, order matching is still centralized. The transaction is performed by the matcher (intermediate quotient) and is therefore not performed on the chain.
The traditional bidding transaction has the following characteristics: 1) In the traditional centralized transaction, bidding relies on a centralized platform to obtain quotations, bid matching, registration and the like, and the requirements on credit and risk bearing capacity of a transaction center node are high; 2) To realize centralized transaction, the asset is required to be hosted in an asset hosting mechanism, the centralized asset hosting mechanism carries out settlement and transfer of the asset, and the risk and settlement condition of a time point are required to be obtained and risk processing is carried out during transfer; 3) The centralized transaction facility has high requirements on the physical performance of a single point and the physical connection performance of a transactor and a transaction system. Due to the characteristics, the centralized transaction system bears financial market risks, and has the advantages of high running cost, limited capacity and high product and customer expansion cost. Meanwhile, the traditional competitive price transaction has high requirements on mobility due to more transaction opportunities, and meanwhile, the situation of flash collapse and the like is easy to occur. Many students consider the rationality of traditional bidding, such as one student thinking that multiple aggregate bidding has the opportunity to replace continuous bidding, and become the mainstream mode of asset pricing.
The blockchain technology provides a new idea for realizing the exchange. The blockchain system has the characteristics of consensus mechanism, encryption transmission mechanism, consistency check mechanism and the like, and is based on a distributed account book and has the characteristics of decentralization and trust. With the development of the blockchain, the new generation blockchain has the characteristics of fast transaction achievement, low-cost trusted verification, intelligent contract support and the like. However, the conventional blockchain system supports functions such as distributed accounting, point-to-point transfer, etc., but does not have a mechanism for decentralizing collective bidding transactions, and cannot form a trusted asset price.
In view of the technical problems of the existing service data processing manner, the inventor proposes a bidding transaction processing scheme based on a blockchain, wherein the scheme is a bidding transaction scheme which can be performed on the blockchain in a decentralizing way, and has the following characteristics: the scheme has low requirements on node performance and credit, and does not need to be completed at a node with specific credit or high physical performance; the proposal can complete the trade achievement and price discovery functions of the traded varieties, and can be qualified as the price-setting function of the traded varieties; and thirdly, the scheme can ensure the safety and the reliability of settlement transfer. The blockchain-based bidding transaction processing scheme is described in detail below.
Fig. 1 is a flow chart of a blockchain-based bidding transaction processing method applied to a system according to an embodiment of the present invention, as shown in fig. 1, the method includes the following steps:
step 101: the competitive price transaction participant node selects at least one competitive price transaction participant node as a transaction processing node;
step 102: a transaction initiating node in the competitive price transaction participant node submits a transaction report; according to the transaction report content, checking and freezing the related funds and assets; transmitting the transaction newspaper to a blockchain network;
step 103: the transaction processing node receives a plurality of transaction newspapers sent by a blockchain network; according to a preset transaction time interval, based on a price quotation priority trading principle in a preset time period, carrying out matching and trading registration processing on all transactions related to transaction newspaper; sending a settlement processing request to a blockchain network;
step 104: and the transaction initiating node receives a settlement processing request sent by the blockchain network, and performs cash processing on funds and assets according to the settlement request.
Compared with the continuous bidding processing scheme in the prior art, the bidding transaction processing method provided by the embodiment of the invention has the beneficial technical effects that:
Compared with the scheme that the bid-dependent centralized platform in the prior art obtains the bid, performs bid matching, registration and the like to finish continuous bid, has higher requirements on credit and risk bearing capacity of a transaction center node, and has higher requirements on physical performance of a single point by a centralized transaction facility, and has higher requirements on physical connection performance of a transactor and a transaction system, the bid transaction processing method based on the blockchain in the embodiment of the invention comprises multiple sets of bid processing, wherein in the process of one set of bid processing, at least one bid transaction participant node is selected as a transaction processing node by the bid transaction participant node, and continuous work of a certain node is not relied on, so that the distributed node performs bid collection, bid matching, registration, settlement and the like, thereby realizing distributed running of the set bid and ensuring efficient, safe and reliable bid transaction.
Compared with the scheme that the centralized transaction is to be realized in the prior art, the asset is required to be hosted in the asset hosting mechanism, the centralized asset hosting mechanism carries out settlement transfer of the asset, and the safety reliability is poor, the scheme provided by the embodiment of the invention obtains the risk and settlement condition of a time point during transfer, the node time of the selected transaction processing node is used as the reference time of one transaction for collective bidding, the risk processing transaction asset and funds are frozen before the transaction, and the safe and reliable performance of bidding transaction processing is ensured.
In addition, the set bidding adopts the bidding price to be in preferential exchange within a specified time period, so that the safe and reliable execution of bidding transaction processing is ensured.
In summary, the competitive price transaction processing method provided by the embodiment of the invention realizes the efficient, safe and reliable competitive price transaction processing.
In particular implementations, blockchains in embodiments of the invention include, but are not limited to, various public, private, and federated chains; the blockchain itself needs to have a consensus mechanism, an encryption mechanism, a consistency check mechanism.
The following describes the steps involved in the embodiment of the present invention in detail with reference to fig. 2.
1. First, the above step 101 is described.
In particular, as shown in fig. 2, the bidding transaction participant nodes on the blockchain selectively generate or designate the transaction processing nodes through an election mechanism, that is, based on a certain consensus mechanism, specifically, the blockchain selects the transaction processing nodes through a consensus algorithm according to the transaction initiating node of the protocol, and the consensus algorithm can be generated through a DPOS consensus algorithm under the private chain environment. Specifically, each transaction participant node may specify one transaction processing node, one transaction processing node or a plurality of transaction processing nodes through comprehensive evaluation on network quality, transaction behaviors of each transaction participant node, and the like.
2. The above step 102 is next described.
In specific implementation, as shown in fig. 2, each transaction initiating node designates an asset account and a fund account, and performs fund verification freezing and asset verification freezing at the same time of quotation, namely, the transaction initiating node submits a transaction report on a blockchain, and locks the related funds and assets according to the contents of the transaction report. The transaction initiating node broadcasts its transaction declaration (transaction declaration) to the blockchain, i.e., the transaction initiating node communicates the transaction declaration to the transaction processing node via the blockchain communication mechanism.
In one embodiment, the transaction statement may include quote price data and its corresponding direction and volume of deals.
When the method is specifically implemented, the transaction newspaper initiated by each transaction initiating node comprises the trading willingness of a plurality of prices, namely quotation price data, and corresponding trading direction and trading volume.
3. The above step 103 is then described.
In one embodiment, the above-mentioned blockchain-based bidding transaction processing method may further include:
after matching and transaction registration processing, the transaction processing node writes the current aggregate bid price data and the transaction amount data into a blockchain ledger and sends the blockchain ledger to a blockchain network; or under the condition of no transaction at this time, writing the highest buying price data and the lowest selling price data into a blockchain account book, and transmitting the blockchain account book to a blockchain network;
The transaction initiating node receives the current aggregate bid price data and the transaction amount data sent by the blockchain network; or highest bid data and lowest ask data.
In specific implementation, as shown in fig. 2, the transaction processing node performs matching and transaction registration on the transaction according to the time specified by the blockchain, sends a settlement request to the transaction initiating node, and sends the bid price and the transaction amount of the round set, if no transaction is made in the round, the highest bid price and the lowest bid price are sent, the data is safe and transparent, and the safe and reliable processing of the bid transaction is ensured.
In specific implementation, as shown in fig. 2, the transaction processing node gathers all transaction newspapers and matches them, performs bidding processing according to a preset standard set bidding flow, and the bid price in the bidding processing cannot be revoked. If no deal is made, the deal processing node is re-asked to bid and the next round of bidding is performed. After the competitive price transaction processing is completed, the content of the received transaction report is stored in a transaction processing node, funds and assets of a transaction initiating node are transferred according to a preset rule of a basic blockchain, and the transfer result is written into a block by the transaction processing node. The transaction processing node writes the transaction price and the transaction amount into the block at the same time, but if one round of transaction is not completed, the transaction processing node writes the optimal buying price or selling price of the last transaction into the block.
In one embodiment, the above-mentioned blockchain-based bidding transaction processing method may further include:
the transaction processing node sends a plurality of processing receipts to the blockchain network after receiving a plurality of transaction receipts sent by the blockchain network and checking the transaction receipts;
the associated transaction initiating node receives a processing receipt sent over the blockchain network.
When the method is implemented, the transaction processing node sends a processing receipt to the transaction initiating node after receiving the transaction report of the transaction initiating node and checking the transaction report to pass, so that the bidding transaction is ensured to be processed safely and reliably.
The inventors have found a technical problem: the trade interval time is determined according to the target price fluctuation in one day. The calculation formula is Argmax { tau } { [ theta ] e (τ)×ψ e (τ) < Threshold }, to ensure that prices are continuously eligible.
Using analysis of the microstructure technology of the market, assuming the market consists of N information traders and M liquidity providers, it can be demonstrated that aggregate bid balancing exists, which must be satisfied:
where ρ can be considered the profitability of the trader per trade, ψ is the asset price volatility. At this time, the market can be cleared at a balanced price. However, when the unpublished information is large, the asset fluctuation is large, and the trading interest of traders is high, the market cannot form a balanced price. Therefore, in view of the above-described technical problems, the inventors propose that in a plurality of aggregate bids, transaction rounds must be comprehensively formulated according to asset fluctuations, unpublished information situations, and the like. Thus, the formula is taken as: argmax { τ } { θ e (τ)×ψ e (τ)＜Threshold}。
That is, in one embodiment, the predetermined transaction time interval is determined based on historical information and market information of the bidding transaction.
When the method is implemented, the transaction is carried out for a plurality of times according to quotation or transaction history, the time interval of each execution is autonomously determined according to the historical information and the referenceable variety pricing, namely, the execution time interval is comprehensively designated by the historical information and market quotation information of the prior transaction, so that the safety and reliability of competitive price transaction processing are improved.
In one embodiment, the predetermined transaction time interval is determined according to the following formula:
Argmax{τ}{θ e (τ)×ψ e (τ)＜Threshold}； (2)
where τ is the transaction time interval; psi phi type e (τ) is an asset transition condition within τ; θ e (τ) is the unpublished information case within τ, which is typically assumed in the application to arrive at Brownian motion of constant intensity, then the unpublished information is θ -e (τ) =λτ, threshold is an empirical value, typically a constant.
In the implementation, the preset transaction time interval is determined according to the formula (2), so that the safety and reliability of competitive bidding transaction processing are further ensured.
4. The above step 104 is next described.
In one embodiment, the above-mentioned blockchain-based bidding transaction processing method may further include:
After the redemption process is finished, the transaction initiating node sends a settlement process finishing receipt to the blockchain network;
and the transaction processing node receives a settlement processing end receipt sent by the blockchain network, and performs blockchain accounting processing according to the settlement processing end receipt.
In specific implementation, as shown in fig. 2, the transaction initiating node performs cash on funds and assets according to a settlement request of the transaction processing node, and sends a settlement end receipt (settlement end receipt) to the transaction processing node after the cash is ended, and the blockchain accounts the generated transaction, so that efficient, safe and reliable processing of bidding transactions is ensured.
An example of which is illustrated in conjunction with fig. 2 to facilitate an understanding of how the present invention may be practiced.
This embodiment illustrates how a matching transaction is implemented in the presence of a transaction processing node-a transaction initiating node.
At T 0 At moment, the block chain selects transaction processing nodes according to the transaction initiating nodes of the protocol through a consensus algorithm, and under the private chain environment, the consensus algorithm can be generated through a DPOS consensus algorithm, so that each transaction participant node can assign one transaction processing node, one transaction processing node or a plurality of transaction processing nodes through comprehensive evaluation of network quality, transaction behaviors of each transaction participant node and the like;
At T 1 At this time, the transaction initiating node broadcasts its transaction declaration to the blockchain, assuming that the transaction object is gold (g), the order format may be as shown in table 1 below:
price of Direction Open flat Quantity of
269(/g) Ask Flat plate 100(g)
268(/g) Ask Flat plate 50(g)
267(/g) Ask Flat plate 20(g)
266(/g) Ask Flat plate 10(g)
265(/g) Ask Flat plate 5(g)
TABLE 1
The record of its assets and funds in the blockchain ledger may be as shown in table 2 below:
funds Asset(s)
300000 1000g
TABLE 2
The node risk check passes, the block chain node locks the funds, the order is broadcast to all block chain nodes, and the transaction processing node receives and replies that the report is successfully received;
at T 2 At the moment, the transaction processing node processes the declaration form and obtains the queue:
queue 1: the buy queue may be as shown in table 3 below:
price of Direction Open flat Quantity of
269 Bid Opening device 100
268 Bid Opening device 200
267 Bid Opening device 500
266 Bid Opening device 900
265 Bid Opening device 1000
TABLE 3 Table 3
Queue 2: the sell queue may be as shown in Table 4 below:
price of Direction Open flat Quantity of
269 Ask Flat plate 1000
268 Ask Flat plate 800
267 Ask Flat plate 600
266 Ask Flat plate 400
265 Ask Flat plate 100
TABLE 4 Table 4
From the above, it can be seen that the buy queue at 267 has 800g buy, 1100g sell. At this point, the transaction processing node sets 267 the reference price, and then equally divides 300g of the open demand to each of the nodes having flat demand.
T 3 At the moment, the transaction processing node sends a settlement request to the transaction initiating node, and sends the matched price to the blockchain node. If there is no deal in this round, the highest bid price and lowest offer are sent.
T 4 At the moment, each node settles and finishes, accounts the blockchain, updates the asset and the fund account and finishes the transaction. And simultaneously calculating the waiting time of the next round according to the fluctuation rate of gold, and preparing to start the next round of bidding.
