Ethereum's Fusaka upgrade just dropped, and honestly? It's all about those backend improvements.

The real winners here are Layer 2 networks. Arbitrum and Base users should see transaction fees drop anywhere from 40% to 60%. Not bad for a routine upgrade.

Meanwhile, the block gas limit jumped from 36 million straight to 60 million—that's a solid 66% boost in network throughput. More space, more transactions, same old Ethereum, just faster.
