zkSync’s Airbender prover can now generate Ethereum L1 block proofs in real-time using only two consumer-grade RTX 5090 GPUs. Vitalik Buterin commended the progress but warned about potential performance gaps and suggested adjusting gas prices for costly operations like RSA verification.

Vitalik Buterin highlights the significance of the PeerDAS feature in Ethereum's Fusaka upgrade, which allows nodes to verify block data without storing it entirely, enhancing scalability. He notes that while the initial rollout will be conservative, PeerDAS is essential for future Layer 1 and Layer 2 scaling, potentially allowing for more efficient data handling and reduced strain on the network.
