Ethereum's Fusaka upgrade just dropped a game-changer: PeerDAS, formally known as EIP-7594.

What's the big deal? Data throughput jumps up to 8x compared to previous limits. For rollups grinding under blob fee pressure, this means two things—cheaper transactions and actual room to scale without hitting capacity walls.

The mechanism redistributes data availability sampling across network peers more efficiently. Instead of every validator downloading full blob data, nodes sample smaller chunks while maintaining security guarantees. Rollups can now pack more transaction data into each blob slot without burning through fees like before.

This isn't just theory. Multiple Layer 2s already testing how much headroom they're getting from expanded blob space.
