Embodiment 1

[0047] Embodiment 1 of the present invention discloses a legal contract-oriented smart contract model construction method, the flow chart is as follows figure 1 shown, including the following steps:

[0048] Step S1: Based on the type of the target legal contract, generate a contract model template and a contract nature template matching the target legal contract;

[0049]Wherein, the contract model template is used to define contract events, contract procedures and contract parameters related to each contract clause in the target legal contract; the contract nature template is used to define each contract in the target legal contract The nature of the behavior that must be satisfied during the automatic execution of a clause. figure 2 It shows the contract flow of the contract model template in the time machine, which also includes contract events such as punishBuyer, submitLate, paymentApproved, submitReg, returnReg, permitReg, and contract parameters such as tolTime and r...

Embodiment 2

[0083] In Embodiment 2 of the present invention, the technical solution in the embodiment of the present invention is clearly and completely described by taking the second-hand housing transaction contract as the target legal contract as an example. It should be noted that, under the inspiration of the technical content disclosed in the present invention, those skilled in the art can apply it to other financial transaction contracts, such as bank financial product contracts, online shopping contracts, etc.; or apply it to other blockchain platforms , such as Ethereum, Hyperledger Fabric, EOS, Libra blockchain platform, etc. Combine now Figure 5 The flow chart of the construction of the legal contract smart contract model is shown, and the detailed description of the specific steps P01 to P05 is as follows:

[0084] Step P01: Determine the second-hand housing transaction contract as the target legal contract category, and generate a contract model template and a contract natu...

Embodiment 3

[0094] This embodiment provides a legal contract-oriented smart contract model building system, the structure diagram is as follows Figure 6 As shown, the system includes: a contract model template and a contract nature template generating module, which is used to generate a contract model template and a contract nature template matching the target legal contract based on the type of the target legal contract; an initial smart contract model generating module , used to obtain the parameter setting result of the user on the contract model template, and use the parameter setting result to configure the contract model template to generate an initial smart contract model; the contract property collection acquisition module is used to use the parameter Set the result and configure the contract property template to obtain the contract property set of the initial smart contract model; the contract property set contains one or more contract properties; the smart contract model buildin...

Abstract

The invention relates to a legal contract-oriented intelligent contract model construction method and system, belongs to the technical field of legal contract-oriented block chain intelligent contracts, and solves the problems of high communication cost, low development efficiency and difficulty in guaranteeing contract correctness and security in the existing intelligent contract model construction process. The method comprises the steps of generating a contract model template and a contract property template matched with a target legal contract based on the type of the target legal contract;obtaining a parameter setting result of a user for the contract model template, configuring the contract model template by utilizing the parameter setting result, and generating an initial intelligent contract model; configuring the contract property template by utilizing the parameter setting result to obtain a contract property set of the initial intelligent contract model; and verifying whether the initial intelligent contract model meets the contract property or not, and if yes, determining that the initial intelligent contract model passes the verification, and taking the initial intelligent contract model passing the verification as a constructed intelligent contract model.

Description

technical field [0001] The present invention relates to the technical field of legal contract-oriented blockchain smart contracts, in particular to a legal contract-oriented smart contract model construction method and system. Background technique [0002] The present invention will be applied to the field of blockchain smart contracts oriented to legal contracts. A smart contract is a special protocol that contains code functions and is used to formulate contracts in the blockchain. It can interact with other smart contracts, and can make autonomous decisions, store data, send tokens, and more. The biggest feature of smart contracts is that the transactions on them are traceable and irreversible. The decentralization, openness, and non-tampering technologies of blockchain guarantee the credibility of smart contracts to a certain extent. Its application scenarios are extensive and its prospects are broad. [0003] However, the current development method of smart contracts ...
