Ethereum’s Fusaka Hard Fork Debuts on Hoodi Testnet

Ethereum’s Fusaka hard fork went live on the Hoodi testnet in late October, marking the last phase before its mainnet debut slated for December 3, targeting significant protocol enhancements.

This upgrade holds importance by promising improvements in Ethereum’s scalability and security, potentially impacting both the mainnet and Layer 2 networks positively, as per Tim Beiko’s Twitter update.

Fusaka’s Impact on Scalability and Security

Ethereum’s Fusaka hard fork has proceeded with consistent moment-to-moment updates, now being tested on the third and final Hoodi testnet. This move marks a critical milestone following previous deployments on the Holesky and Sepolia testnets. The Ethereum Foundation has provisionally set mainnet activation for December 3, 2025.

The Fusaka upgrade will involve implementing at least a dozen Ethereum Improvement Proposals (EIPs). Fusaka ensures enhanced blockchain functions including increased block gas limits and advanced blob capacity, vital for scalability and security. Vitalik Buterin, Ethereum’s co-founder, stressed that the PeerDAS innovation will enable Ethereum to support the next wave of Layer 2 growth by shifting the data bottleneck.

“PeerDAS will radically shift the bottleneck for L2s—blobs will be lighter to sample rather than heavy to verify. This math means it’s time for Ethereum’s data capacity to jump forward.”

Market observers have been closely following the Fusaka enhancement, with Tim Beiko, Protocol Lead at Ethereum Foundation, stating that Fusaka’s success hinges on the stability of the Hoodi testnet, as highlighted in his active discussions on social media platforms. Blockchain enthusiasts and developers have echoed optimism about potential performance boosts and cost reductions within the Ethereum network.

Fusaka’s Economic Potential and Market Dynamics

Did you know? PeerDAS could transform Ethereum’s data availability network, marking a pivotal change parallel to the Shanghai upgrade, which significantly boosted staking inflows in early 2023.

Ethereum’s latest market data reveals a current trading price of $3,986.00 with a market cap of 481,102,261,475.00 and a market dominance of 12.66%, as reported by CoinMarketCap. Recent price changes show a 3.26% decline over the past 24 hours, but a rise of 2.83% over the last week. The trading volume in the past day saw a decrease of 3.96%, amounting to 39,706,335,797.00.

Insights from the Coincu research team suggest Fusaka may unlock broad economic opportunities for Ethereum’s Layer 2 networks, potentially rivaling earlier significant upgrades such as Dencun, which notably increased activity across Ethereum-based tokens like ARB and OP. The outcomes will largely depend on the seamless execution of Fusaka’s mainnet launch.
