Following the successful Pectra upgrade earlier this year, which pushed $ETH’s price up 📈, the network is now preparing for Fusaka - focused on speed, scalability and lower fees.
It introduces PeerDAS, letting validators verify only fragments of data instead of the whole set - a big win for performance and decentralization. It also increases blob capacity, allowing L2s (Arbitrum, Optimism etc) - to pack more transactions per block and cut fees for users.
In simpler terms, after Fusaka, Ethereum will become:
- faster
- cheaper (!) ;
- more L2-friendly ;
- optimized for heavier activity.
Launch set for December 3 - if it goes as cleanly as the testnets, $ETH could head into 2026 with both stronger fundamentals and renewed market confidence.
