Ethereum's Layer 2 solutions, like rollups and sidechains, significantly enhance scalability by processing transactions off-chain while leveraging the main chain's security. They offer lower fees and faster confirmations, making them ideal for high-volume applications like DeFi and NFTs. However, they can't fully replace main chain transactions. The main chain remains critical for final settlement, security guarantees, and decentralized validation. Layer 2 solutions depend on the main chain for data availability and dispute resolution. Certain high-stake transactions, requiring maximum security or direct smart contract interactions, are better suited for the main chain. While Layer 2 handles most everyday transactions efficiently, the main chain's role as the trust anchor ensures it remains indispensable. Both layers complement each other, creating a balanced ecosystem where Layer 2 scales throughput, and the main chain provides unmatched security.
