As Ethereum's popularity surges, network congestion leads to soaring gas fees that price out everyday users. Enter Layer 2 networks. By processing transactions off-chain, they break the gas ceiling, drastically reducing costs to pennies. This efficiency unleashes microtransactions, enabling new types of frequent, low-cost activity. Beyond individual savings, this marks a broader economic shift, driving broader DeFi growth by making the ecosystem accessible to all. Ultimately, Layer 2 solutions are no longer optional but essential for Ethereum's future, bridging the gap between high-tech potential and everyday usability.
