What Is ‘Cross-Chain Interoperability’ and How Do Oracles Facilitate It?

Cross-chain interoperability is the ability for different independent blockchains to communicate and exchange data or assets securely. Oracles facilitate this by acting as a trusted, decentralized messenger that relays cryptographically verified information from one blockchain to another.

This allows smart contracts on one chain to react to events, prices, or state changes that occur on a completely separate chain.
