What is Multi-Chain?

Multichain is a kind of blockchain technology that occurs when several chains link to one another in a federated setting. Federated chains maintain the independence of each individual network while enabling permissioned access between designated entities. Participants on a chain must agree on a set of standards before they may transact with each other. This configuration allows for the safe upkeep of private data stores, with each network managing its consensus method on its own.

Each Decentralized Application (DApp) instance in a multi-chain ecosystem has smart contracts that are separate from apps running on various blockchains. New on-chain settings raise overall aggregate throughput as the multi-chain ecosystem develops, drawing more users with less transaction costs. In this context, scalability, decentralization, method design, consensus, execution, data availability, and privacy are all approached differently by each network.
