Ethereum's about to flip the switch on Fusaka today—and we're talking potential scalability shooting past 100,000 TPS. That's not just incremental; it's a different ballgame for network throughput.

So what's actually changing under the hood? Fusaka brings adjustments that directly impact how Layer 2 solutions operate, transaction costs for everyday users, and the toolkit developers work with when building on Ethereum. Whether you're deploying contracts, bridging assets, or just trying to understand why gas fees might shift—this upgrade touches all of it.

The implications stretch across the entire Ethereum ecosystem, from rollup efficiency to validator incentives.
