In the blockchain context, interoperability refers to the ability of different blockchain networks to communicate and interact with each other efficiently. This capability enables the exchange of information and value across diverse blockchain systems, facilitating seamless transactions and interactions. Interoperability is crucial for overcoming the limitations of isolated blockchain ecosystems, allowing for broader adoption and more complex applications. Techniques to achieve interoperability include cross-chain transactions, sidechains, bridges, and layered protocols. The goal is to create an interconnected network of blockchains, enhancing functionality and user experience while maintaining the individual characteristics of each blockchain.
