Description
Technical Field
The invention relates to the technical field of computers, in particular to an execution method, device and system of an intelligent contract.
Background
A contract refers to an agreement commitment that the transaction participants have agreed to each other. In 1996, nike-sabo proposed the concept of an intelligent contract: an intelligent contract is a set of commitments, specified in numerical form, that contains an agreement on how two parties fulfill the commitments. Smart contracts are currently generally considered to be a computer protocol intended to propagate, verify or execute contracts in an informational manner. Smart contracts allow trusted transactions to be conducted without third parties, which transactions are traceable and irreversible. The basic properties that an intelligent contract contains include: consistency, customizability, observability, verifiability, enforcement, privacy protection. Observability refers to the ability of principals to observe contract performance or demonstrate themselves to other principals; verifiability refers to the ability of a principal to prove contract performance or a breach to an arbitrator, or the arbitrator's ability to ascertain this by other means; privacy refers to the contract content and control of the contract should be distributed only within the scope of participants necessary for contract performance; reputation, intrinsic incentives, "self-enforcement" protocol, and verifiability all play an important role in implementing enforceability.

And, the intelligent contract verification unit may be further operable to: and verifying the execution result according to the intelligent contract, the execution condition, the intelligent contract corresponding to the digital currency processing operation and the service data.
Fig. 2 is a schematic diagram of an implementation principle of the intelligent contract execution system according to an embodiment of the present invention. As shown in fig. 2, the intelligent contract execution system may mainly include a user interaction layer, an intelligent contract execution layer and an intelligent contract verification layer according to different implementation of execution subjects and functions.
(1) The user interaction layer has the main functions:
1) the user interaction layer completes a UI interaction process that a user signs and executes with an intelligent contract through a merchant service APP in the using process;
2) a user acquires an available intelligent contract list through a merchant service APP, and selects an intelligent contract to sign a contract with a merchant or starts contract service provided by the merchant from the displayed intelligent contract list so as to initiate the signing operation of the intelligent contract or start the operation of the intelligent contract;
3) the user can also directly initiate an intelligent contract service request to the intelligent contract execution unit, and the intelligent contract execution unit calls back the merchant service APP node to start the corresponding intelligent contract service. Therefore, the execution of the contract does not depend on the unilateral intention of the merchant, and can be executed according to the intention of the user, so that the execution mode of the contract is more flexible;
4) the user can sign the digital currency involved when the fund processing is involved in the execution process of the intelligent contract, the fund processing unit provides digital currency signature verification, and then the digital currency system completes the actual processing of the digital currency.
(2) The intelligent contract execution layer has the main functions:
1) the execution of the intelligent contract is calculated and executed at an intelligent contract execution unit, namely the intelligent contract execution unit is responsible for executing the contract according to the contract parameters;
2) the execution process of the contract is roughly: the intelligent contract of the user interaction layer is responsible for collecting service data, constructing a data packet which accords with the intelligent contract of the intelligent contract execution layer, and then loading the intelligent contract for execution; the business data comprises business data generated by interaction between a user and a merchant or third-party business data acquired through an external system, and the business data comprises data associated with an intelligent contract;
3) in the execution process of contracts, if the intelligent contracts cannot be found from the local cache, pulling from the intelligent contract library, and similarly, when the execution result of the intelligent contracts is verified subsequently, acquiring the intelligent contracts from the intelligent contract library;
4) the intelligent contract execution layer calls an API of the fund processing unit by a contract code to start fund processing when the fund processing is involved in the execution process of the intelligent contract, and after a user signs a digital currency by using a private key, the fund processing unit performs signature verification and then the digital currency system completes the fund processing. According to the intelligent contract execution method, the capability of converting expected services into digital assets can be provided. The execution of the intelligent contract has clear rules, expected clear transactions can be generated, the data of the fund level of the transactions can be used for constructing a user and merchant wind control mechanism, and the intelligent contract further has the capability of converting the transaction expectation under the intelligent contract into transferable digital assets.
(3) The intelligent contract verification layer has the main functions:
1) after the intelligent contract execution unit finishes the execution process of the intelligent contract, the contract execution result data is packaged and sent to the intelligent contract verification unit for verifying the contract execution result, so that a notarization (verification) signature is given to the execution result of the intelligent contract to ensure the accuracy of the intelligent contract execution result;
2) the intelligent contract verification unit executes the intelligent contract according to the contract requirements and the contract parameters to verify the contract and signs after the verification is passed. After verification, the contract data and the signature are stored in the intelligent contract verification unit for the user to check, and the verification signature is returned to the intelligent contract execution unit, so that the intelligent contract execution unit stores the contract transaction data and the verification signature, thereby completing the execution process of the intelligent contract. Namely: after the verification of the intelligent contract execution result is completed, the intelligent contract execution unit and the intelligent contract verification unit store the same transaction data copy for the execution of the intelligent contract. Thus, the credibility of the capital data can be improved. And the fund transaction data is stored in a warehouse and is stored in multiple points, so that the fund transaction data is difficult to change. The data credibility comes from the realization endorsement of a technical layer (endorsement refers to the behavior that a ticket holder transfers ticket rights to other people or grants certain ticket rights to other people to exercise, records related matters on the back of a ticket or a sticky note and signs a signature), and is irrelevant to the intention of a commercial institution; meanwhile, after the intelligent contract is executed, source tracing and checking can be carried out afterwards according to data reserved by the execution unit and the verification unit;
3) the intelligent contract registers timing requirements or contract execution conditions in the contract trigger unit at the time of signing if timing or conditional execution is involved. And starting an intelligent contract execution process by the contract triggering unit according to the timing condition or the service condition.
In addition, in the embodiment of the present invention, the contract triggering unit may be a timing task for timing triggering execution of the intelligent contract; or an execution condition judgment task for triggering the execution of the intelligent contract according to whether the execution condition is satisfied. The merchant and the user can register the contract triggering unit, and after the intelligent contract execution unit passes the approval, the contract triggering unit can trigger the execution of the intelligent contract at regular time or according to the execution condition. In addition to executing intelligent contracts periodically or conditionally, the contract trigger unit may also be used to ensure the enforcement of intelligent contracts. If the situation that the merchant side refuses to execute the intelligent contract (for example, the user sends a refund transaction to the merchant, and the merchant abandons the transaction not to execute) occurs, the intelligent contract is forcibly executed at the intelligent contract execution unit end.
The intelligent contract registers a service monitoring condition with a contract triggering unit during execution of the contract if the contract execution triggered by the service condition is involved. And the contract triggering unit is used for setting the service condition and the monitoring frequency according to the service monitoring condition. And monitoring whether the service condition meets the execution condition of the contract or not according to the set monitoring frequency, and if so, triggering the contract to be executed on the intelligent contract execution unit by the contract triggering unit.
The data source plug-in is a bridge for the intelligent contract to obtain information from an external data source. During execution of a task triggered by a contract trigger unit, it may be necessary to retrieve data from an external data source. For example, the business of an intelligent contract is aviation delay insurance, and when an airplane fails to take off on time, the client is automatically compensated. At this time, the intelligent contract needs to obtain delay information of the airplane from the airline company. An airplane delay information inquiry interface provided by an airline company can be registered as a data source plug-in.
