Blockchain interoperability is the ability of different blockchain networks to communicate with each other, share data, and work together without the need for intermediaries. With this blockchain technology, digital assets or information from one blockchain can be transferred and used on another. For example, through cross-chain bridges, you can send tokens from Ethereum to Solana without losing functionality. As a concrete example, Cosmos Network has introduced the Inter-Blockchain Communication Protocol (IBC), which allows independent blockchains to communicate seamlessly.
Other projects, such as Polkadot, use the concept of para chains to create efficient interoperability between blockchains. In simple terms, interoperability is the link that allows various previously standalone blockchains to become part of a larger, more inclusive ecosystem. As such, users and developers can utilize the advantages of various blockchain networks without being hindered by technical limitations.
