Ethereum Fusaka Upgrade Live Dec 3: 5× Gas Limit & PeerDAS

Published: 2025-10-31 10:38:02 |

Ethereum Fusaka Upgrade goes live on mainnet on December 3. This major protocol update boosts the block gas limit from 30 million to 150 million units. It integrates PeerDAS (EIP-7594) to improve Layer 2 data validation by sampling blob data. The upgrade follows successful testnet runs on Sepolia, Holesky and Hoodi, and builds on Dencun and Shapella enhancements as part of the Surge roadmap. A four-week security audit tournament offers $2 million in rewards. Despite $220 million in recent ETH liquidations, the Ethereum Fusaka Upgrade enhances network throughput, scalability and resilience. Traders should watch gas fees, layer-2 integration and preparation for future danksharding.

Bullish

The Ethereum Fusaka Upgrade is a positive scalability catalyst. In the short term, the 5× gas limit increase and PeerDAS integration may boost on-chain activity by lowering Layer 2 costs and speeding up data verification. The $2 million audit incentive adds security confidence. In the long term, this step in the Surge roadmap—building on Dencun and Shapella—lays groundwork for danksharding and enhanced DeFi adoption. Overall, the upgrade strengthens network throughput and resilience, making it a bullish signal for ETH traders.
