Description

Method for Providing Service Platform based on Blockchain by using Smart Contract}

The present invention deposits cryptocurrency for a blockchain-based service specified in a smart contract executed in a decentralized manner through M (M≥2) node devices provided on a designated external blockchain network. Designated block based on cryptocurrency deposited in the smart contract on the external blockchain network through the internal blockchain network, which is distinguished from the external blockchain network and implements a unique blockchain algorithm for providing the designated blockchain based service. It is to provide a blockchain-based service platform that provides chain-based services.

Smart Contract is a concept proposed by Nick Szabo in 1994. After programming the terms and conditions of a contract using a designated programming language, the contract is automatically displayed when the terms are met. Is a technology to run with. However, since digital materials such as smart contracts can be easily manipulated or forged in a network environment, smart contracts existed only as concepts and could not be used for concrete services for some time. As it is applied, it is used for concrete services.

The first (or primitive) blockchain-based smart contract is a Bitcoin script applied to Bitcoin. However, Bitcoin scripts had limitations such as not being able to use loops and managing information other than Bitcoin balance. Therefore, on July 30, 2015, Ethereum, a blockchain platform supporting smart contracts that can use loops and manage various information and states, was developed by Vitalik Buterin. All blockchain platforms being developed or under development support smart contracts by default.

On the other hand, since blockchain is optimized for issuing and trading cryptocurrencies and has a small scale, it is difficult to apply conventional blockchain technology to other services in addition to issuing or trading cryptocurrencies. If you want to apply blockchain technology to other services besides issuing or trading cryptocurrency, you have to design a separate blockchain optimized for the service to be applied from the beginning and issue a cryptocurrency accordingly, and apply a conventional blockchain or cryptocurrency. Therefore, there is a technical difficulty to provide a blockchain-based service.

An object of the present invention for solving the above problems is a blockchain designated in a smart contract executed in a decentralized form through M (M≥2) node devices provided on a designated external blockchain network.
