The current blockchain world presents a pattern of "multi-chain parallelism", but the barriers between chains severely restrict liquidity and user experience. Bitlayer has shown new possibilities in cross-chain interoperability. It not only supports seamless integration with Bitcoin but also connects other mainstream blockchains, enabling the free flow of assets and information. For users, this means no need to switch back and forth between different chains, leading to smoother operations; for developers, this offers a broader market and more diverse application scenarios. In the future of cross-chain interoperability, Bitlayer may play the role of a "bridge".
