Blockchain trillema usually points to three issues: scalability, decentralization, and security. Bitcoin and Ethereum, for example, have a scalability problem that slows down the transaction processing speed per second (TPS) as the network expands. To solve this problem, the 3rd generation blockchain EOS appeared, but it has not yet been able to provide a sufficient solution.
ReapChain solves this problem with a hybrid blockchain with a shell-core structure and a new thing authentication system PID. The shell-core structure is a hybrid blockchain that combines ReapMiddleChain, private blockchain and public blockchain. It is a structure in which a fast private blockchain is placed outside and processed first in time. A public blockchain with strong security and decentralization is placed inside to enable dual processing.
