[ detailed description ] embodiments
For better understanding of the technical solutions of the present invention, the following detailed descriptions of the embodiments of the present invention are provided with reference to the accompanying drawings.
It should be understood that the described embodiments are only some embodiments of the invention, and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The terminology used in the embodiments of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. As used in the examples of the present invention and the appended claims, the singular forms "a," "an," and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.
Technical term interpretation:
intelligent contract
An intelligent contract refers to a computer protocol that enables self-execution (self-validation) and self-verification (self-verification) once formulated and deployed, and that does not require human intervention. From a technical point of view, an intelligent contract may be considered a computer program that autonomously performs all or part of the contract-related operations and produces corresponding evidence that may be verified to demonstrate the effectiveness of the contract operations. Before deploying the intelligent contracts, the logic flow of most of the terms related to the contracts is established. Intelligent contracts are typically provided with a user interface (interface) to allow a user to interact with the contracts that have been established, all in strict compliance with previously established logic.
The intelligent contract has the following advantages: (1) efficient real-time updating; (2) accurate execution is carried out; (3) lower risk of human intervention; (4) removing the centralized authority; (5) lower running cost.
Ether house
Etherhouse is a universal global block chain, as well as platform and programming languages, including digital currency ethernet (Ether), and ethernet scripts (EherScript) used to build and publish distributed applications. Additionally, from a bottom-level perspective, etherhouses are a multi-tiered, open source technology protocol based on cryptography. The different function templates of the system are comprehensively integrated through design, and the system is a platform for creating and deploying decentralized application as a whole.
Account
Each account is determined by a pair of private and public keys. Each account has an address.
Wallet
The wallet maintains a database of private keys of the user and manages the amount of the user, providing transactions in corresponding digital currency (e.g., ethernet, etc.), such as payment, transfer functions.
Wallet address
The wallet address is the cash address of the wallet, and is generally a string of character strings used for transferring money.
Trading
A transaction refers to a signed data packet storing a message sent from an external account number. The transaction contains the recipient of the message, a signature to confirm the sender, the ethernet account balance, data to be sent, etc.
Fig. 1 is a flowchart of a processing method based on a blockchain intelligent contract according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step 101: a user selects a corresponding intelligent contract template from a plurality of different intelligent contract templates in a block chain network according to an application scene;
step 102: the user fills in necessary variables in the intelligent contract template;
step 103: and generating a complete intelligent contract to be deployed in the block chain network.
In a preferred embodiment, the blockchain network of the above processing method is an ethernet blockchain. The Ethernet workshop is provided with an Ethernet virtual machine built on a block chain, and the intelligent contract writing becomes simple due to the introduction of the virtual machine. The Ethernet virtual machine is a code running environment established on an Ethernet workshop blockchain, is stored on each node computer, and runs the virtual machine by each check node participating in the Ethernet workshop network and takes the virtual machine as a part of a blockchain validity check protocol. Each node performs the same calculations for deployment and invocation of the smart contract and stores the same data. To ensure that the most authoritative and true results are recorded in the blockchain.
In addition, the processing method further comprises that a plurality of different kinds of intelligent contract templates in the implementation step 101 are established in advance in an intelligent contract template library. The intelligent contract template exists in the blockchain, is written by other users through an intelligent contract language (identity, Serpent and LLL programming languages), runs through an Ethernet virtual machine, and is deployed on the blockchain after being confirmed through different check nodes. A plurality of different kinds of intelligent contract templates are managed and classified in a unified way through an intelligent contract template library. The user can select different types of intelligent contract templates according to different requirements. These intelligent contract templates can be applied to credit agreements of any one of lease contracts, debit contracts, purchase contracts, and sales contracts. The user can select corresponding labels in the intelligent contract template library according to actual requirements, and the intelligent contract template library can call a plurality of intelligent contract templates of the same type for the user to select.
When a user wishes to use the intelligent contract template library in the blockchain above, the user needs to generate a corresponding blockchain account on the blockchain, the account having a wallet address. Preferably, if in the etherhouse blockchain, the user-generated account may be an External Owned Account (EOA) or a contract account. Either the external account or the contract account contains the currency balance status in the corresponding wallet address. Wherein the contract account also contains a contract storage status.
When a user has an account, different kinds of intelligent contract templates in the intelligent contract template library can be called. The intelligent contract templates comprise necessary variables which need to be filled by the user, and if the user cannot provide or fill the corresponding necessary variables, the intelligent contract template cannot be published and checked as a complete intelligent contract and is an invalid contract.
In particular, since most users of a blockchain are very difficult to write a corresponding intelligent contract in an intelligent language. Therefore, in the application, the user can fill in necessary variables in the selected intelligent contract template through the non-intelligent contract language, and then becomes the intelligent contract language matched with the corresponding intelligent contract template after algorithm processing.
As shown in fig. 2, in step 103, the method further includes: after the user fills in the non-intelligent contract language according to the necessary variables in the intelligent contract template, the corresponding algorithm is needed to be adopted for processing, and the corresponding intelligent contract language is converted. I.e. to convert the plaintext into the corresponding code, i.e. the semantics of the intelligent contract. The algorithm can be integrated in an intelligent contract template library, and when a user calls one specific intelligent contract template, the intelligent contract template library can start a corresponding algorithm conversion program. When the user inputs the corresponding necessary variables, the algorithm program can extract the necessary variables, then the necessary variables are converted and stored in the corresponding intelligent contract, and therefore the complete intelligent contract is generated.
For example, when a user A has a blockchain account, a user B also has a blockchain account; when two parties of the first and the second want to sign a house leasing contract in an intelligent contract mode, the first user provides houses for the second user, and the second user pays house leasing expenses to the first user regularly according to a rent agreed by the two parties. At this time, the first user and the second user can select the intelligent contract template of the corresponding house leasing contract from the intelligent contract template library of the block chain, and the intelligent contract template comprises necessary variables which need to be filled by the first user and the second user. The necessary variables are information such as the initial rent date of the house, the rent amount of the house, the payment time of the rent, the validity period of the house lease contract, the names of the two parties of the lease, the identification number, the contact mode, the real estate number of the house and the like; and the variables such as the money amount to be paid by the users A and B after the default behavior occurs.
The first user and the second user fill the variables in natural language through own block chain accounts respectively. If the contract validity period is as follows: 2018.1-2018.12; the names of the users are Zhang three and Li four; if the first user violates the contract, the first user needs to pay the second user with 2 times of the contract fee, and the like. When the necessary variables are completely filled by the first user and the second user, the necessary variables are extracted by an algorithm program, then the converted intelligent contract language is carried out, for example, the information is converted into a Solidity programming language, and then the intelligent contract language is matched with the selected intelligent contract template to generate a proprietary complete intelligent contract for house leasing between the first user and the second user. As shown in fig. 5, the transaction terminal issues the intelligent contract to the whole block chain, and after the plurality of accounting nodes verify the intelligent contract, the intelligent contract is approved, that is, the complete intelligent contract is deployed to the block chain.
It should be noted that in the present embodiment, the intelligent contract template is preferably a credit agreement between at least two users, such as the house rental contracts exemplified above, but is not limited thereto, and may also be a rental contract, a loan contract, a purchase contract, a sale contract, and the like between two parties and multiple parties. And will not be specifically exemplified here. Because the contracts are contracts of two parties or multiple parties, the two parties or the multiple parties can complete the signing of the intelligent contract only by filling in necessary variables provided in the intelligent contract template.
When the intelligent contract is deployed, the processing method further comprises calling and executing the intelligent contract, and when a transaction application is completed, the payment mode of the corresponding user can be that the virtual currency balance payment of the block chain account of the corresponding user is adopted or the payment can be carried out through a third party payment account of the user.
Specifically, following the above example, the intelligent contract for house rentals between the first and second customers is approximately after deployment is complete on the net. If the house renting payment date agreed by the contract is reached, for example, 2018.7.1, the second user needs to pay 3 virtual currencies to the first user, a transaction application occurs at this time, the house renting intelligent closing date is called and executed, as shown in fig. 5, each accounting node of the whole network checks and audits the transaction, and when the check and audit are passed, that is, the transaction application is completed, the account balance of the second user is automatically transferred to the account balance of the first user by 3 virtual currencies. In addition, if the account balance of the second user is less than 3 virtual currencies at the moment, the virtual currency payment can not be realized. The payment can also be carried out through a third party payment account of the second user, for example, the actual bank account of the second user, and the actual bank account balance of the second user is allocated to the account balance of the first user by converting the equivalent of 3 virtual currencies into the corresponding amount of the actual currency.
On the basis of the above embodiments, fig. 3 is a schematic diagram of a processing system based on a block chain intelligent contract according to an embodiment of the present invention.
As shown in fig. 3, the system 100 includes: an intelligent contract template selection unit 12, a variable storage unit 13 and a deployment unit 14, wherein,
intelligent contract template selection unit 12: the intelligent contract template selection method comprises the steps that a user selects a corresponding intelligent contract template from a plurality of different intelligent contract templates in a block chain network according to an application scene;
the variable storage unit 13: the intelligent contract template is used for filling in necessary variables in the intelligent contract template by a user and storing the necessary variables;
the deployment unit 14: the method is used for deploying the generated complete intelligent contracts into the blockchain network.
In addition, preferably, in the embodiment of the present invention, the system 100 may further include an account generating unit 11, configured to generate blockchain accounts of the users, where each account has a wallet address in the embodiment of the present application.
Preferably, the system 100 further comprises an intelligent contract template library, wherein a plurality of different kinds of intelligent contract templates are established in the intelligent contract template library in advance. The intelligent contract template exists in the blockchain, is written by other users through an intelligent contract language (identity, Serpent and LLL programming languages), runs through an Ethernet virtual machine, and is deployed on the blockchain after being confirmed through different check nodes. A plurality of different kinds of intelligent contract templates are managed and classified in a unified way through an intelligent contract template library.
The user selects the required intelligent contract template through the intelligent contract template selecting unit 12, then fills in the corresponding intelligent contract template in the non-intelligent language, the variable storage unit 13 stores the necessary variables filled in by the user, and then the system further comprises an algorithm processing unit (not shown in the figure), and the algorithm processing unit reads the storage information in the variable storage unit 13, namely the information of the necessary variables; the necessary variables filled in by the non-intelligent contract language are converted into the intelligent contract language after being processed by the algorithm processing unit, so that a complete intelligent contract is generated.
After the user fills in the non-intelligent contract language according to the necessary variables in the intelligent contract template, the corresponding algorithm is needed to be adopted for processing, and the corresponding intelligent contract language is converted. The algorithm can be integrated in an intelligent contract template library, and when a user calls one specific intelligent contract template, the intelligent contract template library can start a corresponding algorithm conversion program. When the user inputs the corresponding necessary variables, the algorithm program can extract the necessary variables, then the necessary variables are converted and stored in the corresponding intelligent contract, and therefore the complete intelligent contract is generated.
The intelligent contract template is preferably a credit agreement between at least two users, such as the house leasing contract exemplified above, but is not limited thereto, and may also be a leasing contract, a lending contract, a purchasing contract, a selling contract, and the like between two parties and multiple parties. And will not be specifically exemplified here. Because the contracts are contracts of two parties or multiple parties, the two parties or the multiple parties can complete the signing of the intelligent contract only by filling in necessary variables provided in the intelligent contract template. In addition, in the embodiment of the present invention, the credit agreement may also be an agreement that needs to be signed before for the enterprise and the enterprise, such as a series of credit agreements of the enterprise to the individual user, and the product or service agreement between the enterprise and the individual user.
As shown in fig. 4, the system 100 may further include a calling and executing unit 15 for calling and executing the smart contract.
Specifically, after the intelligent contract is deployed, when a transaction application occurs, the intelligent contract is invoked and executed, as shown in fig. 5, each accounting node in the whole network checks and audits the transaction, and when the check and audit is passed, that is, after the transaction application is completed, the intelligent contract is automatically executed, for example, corresponding payment operation is performed. In this embodiment of the application, the payment method adopted by the payment operation may be a virtual currency balance payment of a blockchain account of a corresponding user, or a payment may be made through a third party payment account of the user.
The method comprises the steps of selecting a corresponding intelligent contract template according to a service scene through user selection, filling in necessary variables in a non-intelligent language mode, and performing intelligent language conversion on the necessary variables in the non-intelligent language filled in by the user through an algorithm so as to perfect a required intelligent contract. The intelligent contract template is combined with the intelligent language conversion technology, so that an ordinary user can easily apply the intelligent contract even if the ordinary user does not understand any intelligent contract programming language, and meanwhile, the intelligent language conversion is only carried out on necessary variables input by the user.
