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

A blockchain system using a micro-chain architecture to ensure transaction processing speed, scalability and security useful for commercial services, the blockchain system comprising:

• a network configured to provide blockchain services,
• wherein the network includes:
• mainnets configured to communicate with other micro-chains in accordance with an inter-chain communication protocol and to issue or burn a coin, and
• a micro-chain architecture including two or more micro-chains in which a smart contract conclusion performed using the coin operates according to each transaction area, wherein the two or more micro-chains are included among the other micro-chains with which the mainnets are configured to communicate, and
• wherein each of the two or more micro-chains is configured to independently perform business transaction logic without interfering with each other, and
• wherein each of the two or more micro-chains is configured to execute a different smart contract corresponding to each of the two or more micro-chains, and
• wherein the micro-chain architecture further includes:
• non-equalizer nodes configured to not participate in consensus and to only share a ledger;
• and
• an equalizer node which is:
• connected to and directly adjacent to the non-equalizer nodes, and
• connected to and directly adjacent to equalizer nodes,
• wherein the equalizer node is configured to collect information of other nodes, to participate in consensus, and to perform verification of the smart contract,
• wherein the other nodes comprise:
• the non-equalizer nodes connected to the equalizer node;
• and
• the equalizer nodes connected to the equalizer node.
