A bridge refers to a mechanism that enables the transfer of digital assets or data between two different blockchains or networks. This is achieved through the use of specialized software or protocols that facilitate interoperability and communication between these distinct systems. Bridges are essential in enabling cross-chain transactions and interactions, as they allow users to seamlessly transfer assets or data between blockchains without the need for centralized intermediaries. Bridges also promote greater decentralization by enabling the creation of diverse, interconnected blockchain ecosystems that can support a wide range of use cases and applications.
