Referring to fig. 1 and fig. 2, fig. 1 is a schematic application scenario diagram of an intelligent contract development method according to an embodiment of the present invention. Fig. 2 is a schematic flowchart of an intelligent contract development method according to an embodiment of the present invention. The intelligent contract development method is applied to the server. The server interacts with the terminal, and users such as developers, maintainers and the like initiate demands through the terminal, and the server invokes contract modules which are in modularized design to develop and expand so as to form intelligent contracts which are developed according to the development demands of the users and can be normalized to be deployed at corresponding nodes.
Fig. 2 is a flow chart of an intelligent contract development method according to an embodiment of the invention. As shown in fig. 2, the method includes the following steps S110 to S150.
S110, acquiring the existing contract.
In this embodiment, the existing contracts refer to conventional smart contracts, and the server will aggregate all the existing contracts in a database, so as to develop a contract module by using a large number of existing contracts.
S120, carrying out modularization processing on the existing contracts according to service requirements to form contract modules.
In this embodiment, the contract modules include a public contract module, a business contract module and a private contract module, and the contract modules are basic modules of the intelligent contract development process, and are used for developing contracts
In one embodiment, referring to fig. 3, the step S120 may include steps S121 to S122.
S121, classifying the existing contracts according to business requirements to form initial modules of various contracts.
In this embodiment, the initial modules of the various contracts refer to existing contracts divided according to service requirements, typically according to public requirements, service requirements and private requirements. Existing contracts are also developed based on business requirements.
S122, designing corresponding interfaces for the initial modules of various contracts to obtain contract modules.
The initial modules of various contracts are based on the concept of business and have unique business attribute functions, so based on the characteristics, the exclusive interfaces of the initial modules are packaged and opened to the outside, wherein public contracts can realize the access of public resources, business contracts can realize the operation of accounts among organizations, and private contracts can realize the privacy security of the accounts of related organizations. The different initial modules require interfaces that implement the operations of the particular modules, the interface functions being specific based on the services provided by the platform.
S130, obtaining the user requirements.
In this embodiment, the user requirement is a request initiated by the user through the terminal, where the user requirement includes a development requirement and a deployment requirement, and of course, the user requirement may include only the development requirement, or the user requirement may include only the deployment requirement.
S140, calling a contract module according to the user demand to develop the intelligent contract so as to obtain the intelligent contract.
In one embodiment, referring to fig. 4, the step S140 may include steps S141 to S142.
S141, calling a corresponding contract module through an interface of the contract module according to the user demand;
s142, assembling and expanding the contract module corresponding to the call according to the user requirement to obtain a processing result.
Each interface is provided with an access document, and a user can rely on the relevant interfaces of the contract modules in development by only reading the access document through the terminal to know the interface designs of different contract modules, so that the development of intelligent contracts can be easily completed, and the development difficulty is greatly reduced. As with the conventional development of intelligent contracts, developers need to encapsulate the development package of the contract module into a common bottom-layer functional operation interface based on the provided interface, i.e. depending on the development package of the contract module, and the developers can also perform additional expansion according to the service characteristics of the developers, so that the convenience of non-invasive plug-and-play is achieved. Specifically, in the expansion process, a contract module and contract characteristics required to be expanded can be integrated to form an intelligent contract.
S150, feeding back the intelligent contract to the terminal.
And feeding the intelligent contract back to the terminal for the user to review, so that the writing maintainability is facilitated.
In the development process of the intelligent contracts, corresponding intelligent contracts can be strictly distinguished and managed, the difficulty of intelligent contract development is effectively reduced through modularized design, the intelligent contract development efficiency and fault tolerance are greatly improved, and a feasibility scheme is provided for the vigorous popularization of intelligent contract modular design
Based on private and shared characteristics of intelligent contract account book data, the modularized design concept is used for intelligent contracts, modularization distinction of public contracts, business contracts, private contracts and the like is provided, the development difficulty of the intelligent contracts is greatly reduced while the privacy security of user data is ensured, and a good design idea is provided for decoupling of the intelligent contracts and implementation of landing.
According to the intelligent contract development method, the existing contracts are subjected to modularized design according to service requirements to form the contract modules, when the intelligent contracts are developed, the contract modules can be called through interfaces corresponding to the contract modules to carry out processes such as expansion and the like, so that the intelligent contracts are formed, the development complexity of the intelligent contracts is reduced, development efficiency is improved for developers conveniently, development cost is reduced, and codes with high maintainability are written.
Fig. 5 is a flowchart of an intelligent contract development method according to another embodiment of the present invention. As shown in fig. 5, the smart contract development method of the present embodiment includes steps S210 to S270. Steps S210 to S250 are similar to steps S110 to S150 in the above embodiment, and are not described herein. Steps S260 to S270 added in the present embodiment are described in detail below.
S260, making an endorsement policy corresponding to the intelligent contract.
In this embodiment, the endorsement policy refers to the deployment rights of the smart contract.
S270, deploying the intelligent contracts on corresponding nodes of the blockchain according to the endorsement policies corresponding to the intelligent contracts.
In view of the modularity of the contract modules, the contract modules are provided with corresponding endorsement policies. The endorsement policy is capable of determining whether a transaction is properly endorsed, as part of a transaction verification process to determine the validity of the transaction, a transaction containing one or more endorsements from an endorsement node. Thus, the public contract module needs to satisfy the endorsement policy of all endorsement nodes, and the private contract module needs to satisfy the endorsement policy of a specific endorsement node.
When the intelligent contracts are deployed, the contract module document is read, the endorsement strategies of different contract modules are known, the intelligent contracts related to deployment can be installed correctly, and the operation and maintenance cost is greatly reduced. In traditional smart contract development, it is ambiguous whether different nodes have rights to contract deployment due to differences in contract traffic. In this embodiment, an endorsement policy corresponding to the intelligent contract is formulated, which is favorable for specifying the deployment authority of the modularized contract in detail. For example, public contracts can be deployed on all nodes, private contracts can only be deployed on proprietary nodes, i.e. proprietary organization nodes, whereas business contracts need to be deployed on nodes with business relevance, i.e. organization nodes with business relevance. Based on the specification of the endorsement policy, when the intelligent contract is managed, the deployment authority of the contract can be rapidly determined based on the exclusive characteristic of the contract module, and then the relevant deployment operation of the contract is carried out, so that the deployment efficiency of the whole intelligent contract is improved.
Based on private and shared characteristics of intelligent contract account book data, the modularized design concept is used for intelligent contracts, modularization distinction of public contracts, business contracts, private contracts and the like is provided, the development difficulty of the intelligent contracts is greatly reduced while the privacy security of user data is ensured, and a good design idea is provided for decoupling of the intelligent contracts and implementation of landing.
