The present invention relates to a synthetic contract model system, and relates to a set of unit contract models or a model for processing a set of these sets. More specifically, a set of inputs and outputs, and a set of unit models constituting a synthetic model. , It consists of a set of lower synthesis models, a relationship that maps data input from outside the synthesis module to the input of the internal configuration model, a relationship that matches input and output between internal models, and a relationship that maps the output of the internal model and the output of the synthesis model. It is a technical field related to a synthetic contract model system through selective combination of unit contracts.

In the case of the concept of smart contract, it was created by Nick Szabo in 1996, but the term and concept of smart contract became widely known through Ethereum.

Ethereum's blockchain network has been operating very stably since the network began operation in 2015. Ethereum's smart contracts are developed using a language called Solidity, which addresses 1) overflow and underflow problems, 2) message call and access permission control problems, 3) reentrancy problems, and 4) short It has vulnerabilities such as address attacks, 5) balance condition invalidation attacks, and 6) DOS attacks.

Vulnerabilities in smart contracts do not end with vulnerabilities, but lead to actual hacking incidents ranging from hundreds of millions to hundreds of billions.

The problem with these smart contracts is that the ideals and goals of blockchain, which is that data cannot be forged or altered and that guarantees the uniqueness, ownership, and asset value of digital assets, are created for the purpose of utilizing blockchain for various purposes, not for anything else. There is a serious problem that ‘smart contracts’ are destroying.

A prior patent document to supplement the performance and stability of smart contracts. For example, a prior patent document that provides a contract for changing the conditions and actions of a contract based on user feedback in a smart contract in which a contract is performed when the conditions are satisfied. As such, there exists an “intelligent smart contract provision method (Publication No. 10-2021-0056745, hereinafter referred to as Patent Document 1).

In the case of Patent Document 1, a service provision step of providing a service based on a scenario including one or more smart contracts required to provide a service using shared resources through a blockchain network, a user terminal or administrator terminal editing the scenario A feedback step of providing feedback, a learning step of training an artificial intelligence learning model that changes the content of one or more smart contracts included in the scenario based on the feedback, and the content of one or more smart contracts included in the scenario by the artificial intelligence learning model. By providing an intelligent smart contract provision method that includes a scenario modification step to change, the conditions and operation of the smart contract can be changed, creating smart contracts with various conditions necessary to provide various types of shared resources to shared services. Available.

As a method to provide reliable smart contract information, it seeks to provide reliability of smart contracts through accurate random number generation by generating reliable random numbers without seed leakage. "Random number generation method and device in smart contracts ( Publication No. 10-2021-0094866 (hereinafter referred to as Patent Document 2) exists.

In the case of Patent Document 2, a method and device for generating pseudo-random numbers in a smart contract are provided. The random number generating device receives a first parameter including seed data for random number generation and also receives a second parameter. And when the first parameter and the second parameter are received in the set order, a random number is generated using the seed data.

Prior literature on methods and systems for implementing smart contracts on blockchains includes “Improved Blockchain-Method and System for Implemented Smart Contracts (Publication No. 10-2021-0090611, hereinafter referred to as Patent Document 3). ) exists.

In the case of Patent Document 3, it includes the step of storing a smart contract in a blockchain with at least one primary block. A smart contract has a set of electronically defined contract terms, each defined by at least one fulfillment value, and the combination of the fulfillment values of the set of contract terms has a fulfillment hash value for the contract. A set of one or more electronically stored secondary transactions, each having a subset of one or more execution values, is read and a subset of transactions corresponding to the contract terms is selected. The execution hash value of the combination of execution values of a subset of transactions is determined. A smart contract is considered fully executed if the execution hash value of the combination of execution values of a subset of transactions matches the smart contract's fulfillment hash value.

In the case of conventional smart contracts, for example, the VM (virtual machine) structure proposed by Ethereum is exposed to the risk that safety cannot be guaranteed from security threats such as hacking.

Accordingly, there is a need for a new smart contract that can guarantee safety in relation to the problems of conventional security and stability, and in the case of the present invention, a model-based development methodology is used to solve problems with smart contracts. We aim to provide stable and reliable smart contracts.
