Ethereum just launched Fusaka on Holesky — the next big step after Dencun. Why big: • PeerDAS (EIP-7594): lets nodes sample blobs instead of downloading full data → scales blob throughput safely. • Gradual blob hikes (BPO forks): target moves from 6 → 10 → 14, ensuring stability as capacity expands. • User impact: steadier rollup fees during spikes, smoother UX for millions on L2s. • Dev upgrades: passkeys (P-256), zk circuit efficiency (CLZ opcode), deterministic proposer schedules. My take: Fusaka tackles the blob congestion that reappeared post-Dencun, unlocking the next phase of rollup adoption. If successful, Fusaka sets the stage for a cheaper, more reliable L2 ecosystem – a critical foundation for Ethereum as it eyes mass adoption in 2026.
