Interoperability Protocol
Also known as: Cross‑chain Protocol, Interchain Protocol
Protocols that enable seamless interaction between different blockchain networks.
An Interoperability Protocol is a blockchain standard or system designed to facilitate the transfer of tokens, data, and smart contract calls across multiple chains. Examples include Cosmos IBC, Polkadot XCMP, and LayerZero. These protocols establish communication layers, consensus verification, and message routing to ensure secure and efficient cross-chain operations. Interoperability protocols are essential for building multi-chain ecosystems, enabling DeFi aggregation, and reducing network fragmentation.
