Layer 2 Bridges
Layer 2 bridges are protocols or mechanisms that enable the transfer of assets and data between a blockchain's mainnet (Layer 1) and its scaling solutions (Layer 2), such as rollups or sidechains. They facilitate interoperability by allowing users to move tokens, NFTs, or other digital assets across different layers while maintaining security and decentralization. This technology is crucial for enhancing blockchain scalability and user experience by reducing transaction costs and latency.
Developers should learn about Layer 2 bridges when building decentralized applications (dApps) that require high throughput, low fees, or cross-layer functionality, such as in DeFi, gaming, or NFT platforms. They are essential for enabling users to access Layer 2 scaling solutions like Optimistic Rollups or zk-Rollups, where assets must be securely bridged from Ethereum or other Layer 1 chains. Understanding bridges helps in designing systems that leverage scalability without compromising on-chain security.
