Description

Contract generating system and generating method
Technical Field
The invention belongs to a block chain technology, and particularly relates to a contract generation system and a contract generation method.
Background
The essence of a blockchain is a decentralized database consisting of a series of growing linked lists of records, called blocks. Each block contains a timestamp and a link to the previous block, which is cryptographically supplemented with information to ensure its integrity and security. The block chain database uses a peer-to-peer (peer-to-peer) network and a distributed timestamp server, and can be applied to a high-fault-tolerance distributed computing system for autonomous management.
In 2014, a blockchain distributed decentralized database concept is proposed, and meanwhile, a programmable blockchain completes programmable blocks, so that a user can complete more elaborate and complex intelligent contracts through a programming means, complete transactions without intermediate guarantee, complete user privacy protection under the economic globalization and monetize the information concept. Subsequently, the superhedger project realizes complete authority control and safety guarantee.
The smart contract of fabric is called chain code (chain code) and is divided into system chain code and user chain code. The system chain code is used for realizing the function of the system level, and the user chain code realizes the application function of the user. The chain code is compiled into an independent application program, the application program runs in an isolated Docker container, and compared with other intelligent contracts, the chain code of the fabric and a bottom account book are written separately, so that the writing independence of the intelligent contracts is ensured, the upgrading of the chain code is also ensured without the migration and conversion of account book data, the separation of logic and data is really realized, and a good contract machine is provided for the independent writing of the intelligent contracts.
Based on the block chain programmable blocks, a user can complete more refined intelligent contract writing through a programming means. Intelligent contracts allow contracts to be automatically fulfilled without human intervention by conditions set by the contract. The existence of blockchains makes each run of a contract public and irreversible, as a "trusted" program, intelligent contracts replace the man-in-the-middle vouching role in traditional contracts, and are more rapid. The intelligent contract ensures that the executing parties and even multiple parties can not be destroyed, and the rights and interests of the contract interest parties are protected. Meanwhile, each document is backed up and encrypted on a network chain, so that the safety and the integrity are ensured. In a cryptocurrency transaction system, each transaction is fulfilled and carried out by a smart contract.
Although each financial business company and the internet industry have optimistic attitudes towards the development prospect of the intelligent contracts, the traditional paper contracts will be replaced by the intelligent contracts in the future, but the mature realization of the intelligent contracts is not realized in the industry at present. In view of the current financial situation, legal executive power and difficulty in compiling intelligent contracts, intelligent contracts also face the following problems:
(1) for most contracts, the writing difficulty of the contracts has high requirements on the speciality of the programs, and most of the people in the financial field and the legal field cannot completely develop the contracts according to the assumed conditions;
(2) the intelligent contract is restricted by the writing of a specific programming language, so that a plurality of financial and legal conditions cannot be effectively realized in the language environment, and a plurality of transactions cannot be achieved due to the inflexible development;
(3) the legitimacy and realizability of intelligent contracts are questioned in the financial field and law enforcement;
(4) potential conditions in the contract field are easy to ignore, and negotiation and interaction between experts in the financial field and experts in the computer field are necessary preconditions for contract development;
(5) because of the interaction of important personal property such as funds, personal information and the like in the transaction process, the problem of how to ensure the information security of the funds also needs attention.

Detailed Description
In order to more specifically describe the present invention, the following detailed description is provided for the technical solution of the present invention with reference to the accompanying drawings and the specific embodiments.
Commercial contracts (including financial fields, legal fields, etc.) are mainly composed of four parts, a contract header, a contract body, a contract tail and a contract attachment. The contract attachment is mainly data of details such as standards and the like outside the contract text and does not belong to the contract generation range for the moment, and the tail part of the contract is mainly a signing column of the contract and is maintained by an execution mechanism of the contract and is not described here. Therefore, for the contract, the most important work is the design processing of the contract header and the contract body, and the contract body is more critical.
The contract header is the content before the formal contract clause, and mainly explains and confirms the identity, the contract name, the contract number and other information of both parties of the contract.
The contract text has the following characteristics:
(1) the contract text is an agreement which is achieved by two parties, is mostly presented in the form of terms, and arranges the contract terms with regular serial numbers, therefore, the contract text can be split;
(2) most of the contracts in the same field have similar terms, for example, the contracts in the financial field necessarily have basic terms such as transaction, inquiry and the like, so the functions of the contracts in the same field can be similar;
(3) most of the contract terms with the same functions are similar or even the same, and the differences are often presented in quantifiable standards such as quantity, quality, parties, price, time and the like, so that the quantifiable values and conditions of the contracts can be changed, and the standards of the contracts can be increased or decreased;
(4) there is no close relationship between the terms, and most contracts are independent of each other, and are not related to each other, so that the contract terms are relatively independent.
Based on the fact that the contract text has the four characteristics, the embodiment provides a contract generating system.
Fig. 1 is a schematic diagram of a contract generation system according to an embodiment. Referring to fig. 1, in the present embodiment, the contract generating system includes a processor 102 and a memory 101, and the memory 101 stores a computer program which is executed by the processor 102.
Fig. 2 is a flow chart of steps executed by the processor in the generation system shown in fig. 1, and specifically includes the following steps:
s201, request receiving step: receiving a contract generation request through a communication line;
s202, contract generation step: based on the received contract generation request, calling a contract framework module to form a contract basic framework, embedding a contract function module in the contract basic framework module and embedding a contract value module in the contract function module, and generating a contract based on the contract generation request;
and S203, a contract feedback step, namely feeding back the generated contract through a communication line.
In the contract generation system, the communication line may be wifi, 3G, 4G, or the like that can be connected to the public network.
In this embodiment, the contract framework modules are divided into two types, one is a contract header framework, and the other is a contract body framework. The contract header frame is used for explaining and confirming the contract information and the contract itself, and can comprise a plurality of styles of contract header frames, and the user can select the contract header frames with different styles according to needs and preferences. The contract main body frame is used for filling contract main body clauses and can comprise contract main body frames with various styles, a user can select to call one contract main body frame according to needs and preferences, the contract main body frames with various styles can be called to be spliced into a contract main body frame which is finally used by the user in a flow program embedding mode, and the contract head frame and the contract main body frame are embedded with flow programs to form a contract basic frame. The procedure embedding means that the contract text frame called this time is embedded into the contract text frame called last time in sequence according to the calling sequence.
In this embodiment, the contract function module refers to a contract term comprising a contract term type, which contains general term contents but lacks contents closely related to the user's will, which are supplemented by the later contract value module. For example: the contract function module is used for representing the payment specification clauses, and the content of the clauses is 'A company needs to pay expenses to B company within XXX days after receiving the expense notice'. Day XXX is content that is closely related to the user's wishes, requiring the latter user to fill in via a contract value module.
In this embodiment, the contract term types may be basic term types such as new account, account transfer, account balance inquiry, account deletion, and the like, or may be fund allocation based on a share right form, account transaction, multi-step flow transaction, branch and aggregate transaction modes, and the like.
In this embodiment, the contract value module is a module providing an input interface for a user, and the user may input a value according to will, where the value may be a word, a number, an object, and the like, such as zhang san, 1000, and Tom.
The system is a single-request invocation principle, i.e. each time any module is invoked, it is based on one request. The specific process of S202 is as follows:
s2021, based on the received contract generating request, calling a corresponding contract frame module to form a contract basic frame;
s2022, based on the received request for calling the contract function module, calling the corresponding contract function module and embedding the contract function module into the contract basic framework;
s2023, based on the received request for calling the contract value module, calling the corresponding contract value module and embedding the contract value module into the contract function module matched with the contract value module.
In S2022, the step of calling the corresponding contract value module and embedding the contract function module matched with the contract value module includes:
and judging whether the called contract value module type is consistent with the contract function module type, if so, embedding the contract value module into the contract function module, and if not, deleting the contract value module and feeding back a mismatch prompt.
The type of the contract function module is the type of the contract clause corresponding to the contract function module, and each type of contract clause has a format of a vacant numerical value. The contract value module type refers to the format of a value input from the outside, and judges whether the type of the called contract value module is consistent with the type of the contract function module, that is, judges whether the format of a vacant value corresponding to the contract function module is consistent with the format of a value provided by the contract value module. For example: the vacant number value type corresponding to the contract function module is character (Zhang III), the format of the number value provided by the contract number value module is number (1000), under the condition, the called contract number value module type is inconsistent with the contract function module type, the contract number value module is deleted, and the mismatch prompt is fed back.
The S202 contract generating step further includes:
and S2024, based on the received request for calling the contract security module, calling the corresponding contract security module and embedding the contract security module into the contract function module. In the process, the contract security module is used for carrying out logic check on the security of the embedding process of the contract value module.
The contract security module is also used for basic account presence checking, account balance checking, account authority checking, and the like.
The S202 contract generating step further includes:
s2026, based on the received request for calling the contract logic body module, calling the corresponding contract logic body module and embedding the contract logic body module into the contract function module.
The contract logic body module comprises judgment logic based on condition establishment, allocation logic based on share of share, control logic based on time and place, execution logic and integrity logic based on operation sequence and the like, and each logic body module is designed for expansibility of basic function addition of the contract, so that the completeness of contract expression is enhanced.
The S202 contract generating step further includes:
and S2027, based on the received request for calling the contract annotation module, calling the corresponding contract annotation module and embedding the corresponding contract annotation module into the contract framework module, the contract function module, the contract numerical value module, the contract security module or the contract logic body module.
The contract annotation module is a general module, and a user can add annotations through the contract annotation module to achieve the detailed description of the text version of the contract.
In order to ensure the safety and legal normalization of the contract, the S202 contract generating step further includes:
and S2028, automatically translating the program codes corresponding to the embedded contract framework module, the contract function module, the contract numerical value module, the contract safety module, the contract logic module and the contract annotation module into characters complying with laws to form a character edition contract.
As each module corresponds to the corresponding execution code, the back of the module can also correspond to the text clause sentence which conforms to the national legal standard. The composition of a text edition contract consists of two parts, the first block is the overall structure and classification of the contract, and the first block is used for explaining the header of the contract and the text range of the contract. The second block is based on the calling of modules such as a contract frame module, a contract function module, a contract numerical value module, a contract safety module and the like, and the core processor intelligently processes the modules through a frame structure and a clause sequence to generate corresponding text version contract annotations and enhance the readability of the contracts. Therefore, the user can conveniently design the contract content according to the requirement, and meanwhile, the legal rules and regulations are complied with, and the potential safety hazard of the contract is reduced.
Based on the above, generating a contract based on the contract generation request includes:
detecting whether all contract functional modules embedded into the contract framework module have vacancies or not, if so, feeding back that vacancy reminding exists for the contract functional modules, and if not, converting all modules used in the contract generation step into program language codes to generate a contract based on the contract generation request.
In the embodiment, functions corresponding to the contract framework module, the contract function module, the contract numerical value module, the contract security module, the contract logic body module and the contract annotation module are packaged into a graphical module and displayed on an interface, and a user only needs to arrange the modules in sequence to change the execution sequence of codes when calling, so that the codes are executed according to the sequence of the intelligent contracts when the contracts take effect, and the function of splicing terms is achieved.
Based on the contract generating system described above, the present embodiment provides a contract generating method including the steps of:
a request receiving step: receiving a contract generation request through a communication line;
a contract generating step: based on the received contract generation request, calling a contract framework module to form a contract basic framework, embedding a contract functional module in the contract basic framework and embedding a contract numerical value module in the contract functional module, and generating a contract based on the contract generation request;
contract feedback step: and generating corresponding executable contract codes after the integrity of the check codes is fed back through the communication line.
Examples
The present embodiment applies the contract generating system provided above to a zone-by-zone intelligent contract.
The user firstly connects with corresponding websites and databases through wifi, 4G and other public networks, and calls the contract frame module to combine through dragging to form a frame required by the user, and then inserts the functional module in the frame in sequence to make contract clause statement, and finally adds the object, the numerical value module, and the like, and finally adds the annotation statement optionally, and increases the contract detail content description.
After the operation, the core processor feeds back corresponding information to the user by checking the safety and the integrity of the code, returns executable code corresponding to the contract if the code is complete, and returns corresponding safety warning if the problems of lack of parameters, low safety, non-uniqueness of the contract body and the like exist.
As shown in fig. 3, a simple financial contract is taken as an example:
1. the user first builds the foundation framework of Init and Body of the foundation.
2. A user calls a set initialization function module in Init to establish two accounts with the names Tom and Jenny, the account values are respectively 100 and 50, and meanwhile, user-related comments can be added in an exception.
3. The user calls the functions of invoke, query and delete in Body, wherein a layer of if logical framework is established outside the invoke to judge and check whether the Tom user has enough money. Secondly, a layer of check judgment of checkexist is added to the three.
The above-mentioned embodiments are intended to illustrate the technical solutions and advantages of the present invention, and it should be understood that the above-mentioned embodiments are only the most preferred embodiments of the present invention, and are not intended to limit the present invention, and any modifications, additions, equivalents, etc. made within the scope of the principles of the present invention should be included in the scope of the present invention.
