A Bridge Chain is a type of blockchain that connects two or more distinct blockchain networks. Its primary purpose is to facilitate communication and transfer of data or assets between these separate chains, enabling interoperability. For example, if you want to move tokens from one blockchain to another, a Bridge Chain acts as a mediator. It can lock assets on the original chain and issue equivalent tokens on the target chain, ensuring that the value is preserved throughout the process.Bridge Chains enhance the user experience by providing access to various decentralized applications (dApps) and ecosystems without being limited to a single blockchain. They also play a crucial role in DeFi (Decentralized Finance) by allowing users to leverage liquidity across different chains.Overall, Bridge Chains help to create a more connected and versatile blockchain landscape, enabling users to benefit from the unique features and advantages offered by various networks.
