Ethereum Layer 2 Benefits: Scalability, Lower Fees, Security
Ethereum Layer 2 solutions provide benefits including improved scalability with throughput increasing from around 10 transactions per second on Layer 1 to potentially over 1,000 tps across all L2s combined, significantly reduced transaction fees that cost pennies instead of twenty dollars or more, and inherited security from the Ethereum mainnet. These advantages make Ethereum more practical for everyday use and support broader adoption. Layer 2 networks offload transactions from the mainnet, which helps prevent congestion and keeps the base layer efficient. Gas fees on L2s are considerably cheaper, making frequent interactions financially viable for decentralized applications that would be too expensive to operate on Layer 1. L2s also offer near-instant transaction confirmations and enable new use cases like gaming and high-frequency trading that would be impractical on the main chain. By processing transactions off-chain, L2s allow Ethereum to remain decentralized since nodes do not need to process every single transaction.
