Definition
Interoperability in blockchain is the ability of separate distributed ledger networks, protocols, or smart contract environments to recognize, reference, and exchange data or value with one another in a reliable, verifiable manner. It describes the conceptual property that allows distinct chains or on-chain systems to interact beyond their native boundaries while maintaining their respective consensus rules and data integrity.
In Simple Terms
Interoperability is the idea that different blockchains and on-chain systems can understand and talk to each other. It means separate networks can share information or value in a coordinated way, without each one needing to exist in total isolation from the others.
Context and Usage
The concept of interoperability appears in discussions about connecting isolated blockchain ecosystems, coordinating data across multiple on-chain environments, and designing infrastructure that can reference external information through services such as an oracle network. It is often mentioned when evaluating whether separate chains, applications, or smart contracts can interact consistently without relying on a single, unified blockchain.
