NestedChain: “Blockchain-inside-a-Blockchain” new generation prototype

Abstract:

New developments of blockchain designs, for both research and commercial environments, focus on improving security and energy consumption. Indeed, these implementations are based on managing a single type of information linked to a single blockchain. In this paper, we propose a new design called NestedChain. This proposal creates a system that allows two completely different types of information to be held in the same physical structure, enabling the creation of a blockchain within a blockchain. The new blockchain design can be implemented in various environments where it is necessary to have two different and parallel sets of information in the same network infrastructure. This new conception of blockchain offers a new way to understand the limitations of existing implementations and suggests how the evolution of the blockchain environment could be enhanced.
