Blockchain provision system and method using non-competitive consensus algorithm and micro-chain architecture to ensure transaction processing speed, scalability, and security suitable for commercial services

Abstract

Provided is a blockchain provision system using a non-competitive consensus algorithm and micro-chain architecture to ensure transaction processing speed, scalability, and security useful for commercial services. The system includes: a network providing the blockchain services. The network includes: mainnets communicating with other micro-chains according to an inter-chain communication protocol and issuing or burning a coin, and a micro-chain architecture connected to the mainnet and including a plurality of micro-chains in which a smart contract conclusion performed using the coin operates according to each area, and the micro-chains independently perform business logic without interfering with each other, and execute different business logics to execute smart contracts corresponding to the micro-chains, respectively.
