Interoperable blockchain refers to the ability of different blockchain networks to communicate and share information with one another seamlessly. This concept is essential because numerous blockchains operate independently, often making it challenging for users and applications to interact across different systems.When blockchains are interoperable, they can exchange data and assets without the need for a central intermediary. This allows for greater flexibility and utility, enabling users to transfer tokens, access decentralized applications, or utilize services across various platforms smoothly.Several projects are working on achieving blockchain interoperability using various methods, including atomic swaps, cross-chain bridges, and protocols that facilitate communication between chains. These advancements aim to enhance the overall functionality and user experience, fostering an environment where diverse blockchain ecosystems can work together cohesively.
