Detailed Description
The present invention will be described in further detail with reference to the following specific examples and the accompanying drawings. The drawings in the following description are only examples of the invention, and it will be clear to a person skilled in the art that other drawings and embodiments can be obtained from these drawings without inventive effort.
For the sake of simplicity, the drawings only schematically show the parts relevant to the present invention, and they do not represent the actual structure as a product. In addition, in order to make the drawings concise and understandable, components having the same structure or function in some of the drawings are only schematically illustrated or only labeled. In this context, "a" does not only mean that
"only one" may also mean "more than one".
An intelligent contract is a special protocol that aims to provide, validate and execute contracts. In particular, smart contracts are an important reason why blockchains are referred to as "decentralized," which allows us to perform traceable, irreversible, and secure transactions without the need for third parties. The smart contract contains all information about the transaction and only after the requirements are met will the resulting operation be performed. Smart contracts differ from traditional paper contracts in that smart contracts are computer-generated. The intelligent contracts are written and operated according to the logic of the functions, and the intelligent contracts used by the blockchain network are executed in a safe and trusted network as long as the input requirements are met, namely, as long as the code writing requirements are met.
However, when there are contract objects and rules that are uncertain, intelligent contracts cannot fulfill their functions instantly, restricting the execution of both parties to the contract. Taking the traditional transaction as an example, the completion of the order needs the determination and authorization of the identities of both contract parties, and has larger time delay and no flexibility and compatibility to contract objects and rules. In order to optimize the static process of the transaction into a dynamic process with stronger compatibility, the intelligent contract needs to be executed and covered for multiple times, and the token pool device is used as a tool to be matched with the intelligent contract to complete the transaction.
In real life, a plurality of scenes need to finish dynamic transactions, such as offline market grouping transactions, group trip transactions and other transaction scenes, two problems exist in the transaction scenes, and according to a group trip behavior example, if a certain transaction amount in one trip is too large to exceed a threshold value of a payment member account, the transaction cannot be carried out; taking offline party sharing as an example, the number of people who are the objects of party sharing cannot be determined, the price of the party sharing changes in real time, and the traditional transaction cannot meet the transaction process in the scene. The technical problems to be solved by the present invention are described above by using offline market grouping and group-making behavior examples, but the present invention is not limited thereto, and in addition to the above, the above problems such as reservation queuing, credit rating, etc. also exist.
In order to solve the problems in the transaction scene, the invention deploys a token pool in advance, the token pool is shared by two modules, an inflow module and an outflow module, and the participants can execute authorization to complete the functions of verification, inflow, locking, matching, calculation, outflow and the like of the token pool through the intelligent contract of the initiator. The participant's authorization may be randomly initiated and the intelligent contract will override over and over again until the token influx lock condition is reached.
It should be noted that, the group play and offline group-piecing transaction described in the following examples of the present invention are only a specific application scenario in which the present invention implements asset deduction on a block chain through an intelligent contract, and are not intended to limit the present invention, and the present invention is broader as long as a token pool supporting the intelligent contract can implement token transaction on the block chain based on the technical solution disclosed in the present invention, such as credit rating, reservation queuing, and the like, which all belong to the protection scope of the present invention.
The method and the device for processing the multi-account intelligent contract flow based on the token pool have two states, namely a public state and a private state.
Example 1:
FIG. 7 is a diagram of an example of a method and apparatus for multi-account intelligent contract flow processing using token pools of the present invention in a common state, which includes two functions:
1) define 1: y ═ f (g) as a regular function
2) Definition 2 g ═ u (x), x ∈ D is the influence factor function
3) Definition 3 dic ═ { N: N, ST: t1,ET:t2,C:c,X1:k1,X2:k2,X3:k3,X4:k4,…,Xn:kn}
Wherein N represents a contract number; ST represents a start time; ET represents the end time; cd represents the token pool state (wherein { Cd:0} is token pool locking state, { Cd:1} is token pool inflow state, { Cd:2} is token pool outflow state, XnIndicating that a specific account is specified; k is a radical ofnIndicating the number of tokens in the given account.
According to the token pool flowing contract, the rule function and the influence factor function need to be transmitted through the rule interface of the token pool flowing contract, and the token pool actuator device is actuated through the contract until the end.
The 5 accounts are A, B, C, D, X, respectively, the rule function is y 30-g, g ∈ [0,15] and there is an influence factor function g (x) ═ x-1, (x ∈ N).
When x is 1, g is u (1), x-1 is 0, and y is f (0) is 30; the number of tokens flowing into the token pool at one time is 30; the token pool status is { N:1, ST:20210101000000, ET:20210101120000, Cd:1, M:30, A:0 };
when x is 2, g is u (2), x-1 is 1, y is f (1) is 29; the number of tokens flowing into the token pool at a time is 29; the token pool status is { N:1, ST:20210101001000, ET:20210101120000, Cd:1, M:58, A:1, B:0 };
when x is 3, g is u (3), x-1 is 2, y is f (2) is 28; the number of tokens flowing into the token pool at a time is 28; the token pool status is { N:1, ST:20210101001500, ET:20210101120000, Cd:1, M:84, A:2, B:2, C:0 };
when x is 4, g is u (4), x-1 is 3, and y is f (3) is 27; the number of tokens flowing into the token pool at one time is 27; the token pool state is { N:1, ST:20210101002000, ET:20210101120000, Cd:1, M:106, A:3, B:2, C:1, D:0 };
after the four participants participate in the token pool, the token pool enters a locking state, the number of the outgoing tokens is transferred to an initiator account by calling an outflow execution sub-interface of the token pool device, and the corresponding number of the incoming tokens is transferred to accounts A, B, C and D by calling an inflow execution sub-interface of the token pool device, so that the whole operation process of the token pool device is completed.
Therefore, the method and the device for multi-account intelligent contract flow processing based on the block chain token pool can realize real-time flow processing of multi-account intelligent contracts in a public state.
Example 2:
FIG. 7 is a diagram of an example of a private state of a method and apparatus for multi-account intelligent contract flow processing using token pools of the present invention, which includes a dictionary:
1) definitions 1 dic ═ x1:k1,x2:k2,x3:k3,x4:k4,…,xn:kn}
According to the token pool flow contract, parameters in a dictionary need to be transmitted through a rule interface of the token pool flow contract, and the token pool actuator device is actuated through the contract until the end.
In this example, let K equal 100, p1＝1/4,p2＝1/4,p3＝1/4,p4＝1/4；
k1＝K*p1＝25；k2＝K*p2＝25；k3＝K*p3＝25；k4＝K*p4＝25
dic＝{x1:25,x2:25,x3:25,x4:25}
After the four participants participate in the token pool, the token pool enters a locking state, the amount of the outflow tokens is transferred into the token pool by calling the inflow execution sub-interface of the token pool device, and the corresponding amount of the outflow tokens is transferred into the corresponding account by calling the inflow execution sub-interface of the token pool device, so that the whole operation process of the token pool device is completed.
Therefore, the method and the device for multi-account intelligent contract flow processing based on the block chain token pool can realize real-time flow processing of multi-account intelligent contracts in a private state.
