Comparing Transaction Speed and Costs: Layer 1 vs Layer 2 Blockchain

One of the biggest pain points of Layer 1 blockchains like Ethereum is network congestion and high gas fees. Transactions can become costly during peak times.

Layer 2 protocols significantly reduce gas fees and increase throughput by batching transactions and settling them on the Layer 1 chain later. For example, Arbitrum and Optimism can reduce gas fees by up to 90% compared to Ethereum mainnet.

Winner: Layer 2 for faster, cheaper transactions.
