Cooperation Model for Improving Scalability of the Multi-Blockchains System

Abstract

Scalability is an open question of the blockchain. Ongoing solutions, like Sharding and Side-chain, try to solve it within an independent blockchain system. We propose a cooperation model by constructing a system of multiple blockchains. In this model, secure cross chain operations can help to handle more requests. The gossip channel can help to refresh the states of other blockchains. Through manage interactions among blockchain systems, this model can limit their misbehaviors and improve scalability.
