Blockchain Interoperability
Also known as: Cross-Chain Communication, Interchain Connectivity, Blockchain Compatibility
The ability of different blockchain networks to communicate and exchange data or assets securely and seamlessly.
Blockchain interoperability is the capacity for multiple blockchain systems to interact with each other, enabling the transfer of tokens, data, or logic across chains. This solves the problem of fragmentation and enhances composability in the Web3 ecosystem. Interoperability can be achieved via bridges, cross-chain messaging protocols (like IBC or LayerZero), and shared security models. It enables use cases such as cross-chain DeFi, asset swaps, and collaborative dApps. Projects like Cosmos, Polkadot, and Chainlink CCIP lead efforts in standardizing secure, scalable interoperability layers.
