Various hybrid blockchains that integrate private blockchain with public blockchain are being developed. However, no hybrid blockchains have resolved the trilemma of the existing blockchains, and are used soundly in real life yet.
ReapChain offers a hybrid blockchain with Shell-Core Structure as a solution to problems of the existing blockchain. Shell-Core Structure is implemented based on PoDC consensus algorithm, a unique consensus algorithm of ReapChain. It is a new type of dual blockchain structure that integrates a public blockchain with a private blockchain.
