A bridge node acts as an intermediary between different blockchains or networks. Its primary function is to facilitate communication and transfer of data or assets across these systems that may otherwise be incompatible.These nodes play a vital role in enhancing interoperability, allowing users to move tokens, execute smart contracts, or perform transactions across multiple platforms. By linking different blockchains, bridge nodes can help reduce fragmentation and unlock new use cases for developers and users alike.In practice, when a user wants to transfer assets from one blockchain to another, the bridge node validates the transaction, ensuring that it meets the necessary criteria. Once verified, the bridge node can initiate the transfer on the target blockchain.Bridge nodes can improve the overall efficiency of crypto ecosystems, making it easier for individuals and applications to take advantage of various features offered by different chains. This connectivity can create a more fluid experience for users, promoting collaboration and innovation within the broader blockchain landscape.
