Ethereum Fusaka Upgrade Final Testnet Ahead of Dec 3 Fork

Ethereum Fusaka upgrade entered its third and final testnet phase with the activation of the Hoodi network on October 29, following Holesky and Sepolia tests. Developers now await a mainnet fork at least 30 days later, targeting December 3. The Ethereum Fusaka upgrade bundles over a dozen EIPs to boost scalability, security and cost efficiency. Key proposals include EIP-7594 (Peer Data Availability Sampling or PeerDAS), allowing validators to verify data fragments instead of full blobs to reduce bandwidth and costs for nodes and Layer-2 networks; EIPs 7825 and 7935 adjust gas limits for parallel execution; and EIPs 7939 and 7951 enhance performance and zero-knowledge proof support. After the December 3 activation, blob capacity increases are set for December 17 and January 7, 2026. Client teams report smooth performance on Hoodi. Ethereum developers are already planning the next Surge roadmap phase, “Glamsterdam,” to further improve parallel execution and ZK rollups. Market observers note that successful deployment may reinforce confidence in Ethereum’s long-term scalability and support ETH price above $4,000, although ETH traded below this level after a 3% dip in 24 hours.
Bullish
The Ethereum Fusaka upgrade marks a significant step in Ethereum’s Surge roadmap by improving scalability, security, and cost efficiency through key EIPs like PeerDAS and gas limit adjustments. Smooth testnet performance on Hoodi and a clear mainnet activation timeline reduce uncertainty and may boost validator and trader confidence. The planned blob capacity increases and subsequent “Glamsterdam” phase signal a robust upgrade path, likely enhancing network throughput and lowering fees. This positive technical outlook and strengthened scalability prospects are expected to have a bullish impact on ETH’s price in both the short and long term.
