The third and final testnet for Ethereum’s Fusaka upgrade is launched.
Ethereum’s long-awaited Fusaka hard fork reached a major milestone on Tuesday with a successful deployment on the Hoodi testnet, its final testing phase before mainnet activation later this year.
The test, which went live around 18:53 UTC, was the completion of Ethereum’s three-stage simulation process following previous activations on the Holesky and Sepolia testnets.
Fusaka Update
According to the Ethereum Foundation, the Fusaka mainnet launch is expected at least 30 days after Hoodi goes live, while the developers are tentatively targeting December 3. The main goal behind the upgrade is to strengthen the scalability, security and profitability of Ethereum, building on the groundwork laid by the April Pectra upgrade.
Fusaka introduces a series of technical improvements spanning more than a dozen Ethereum Improvement Proposals (EIPs). Topping the list is EIP-7594, or Peer Data Availability Sampling (PeerDAS), which allows validators to verify only portions of data, rather than entire “blobs,” and significantly reduces bandwidth demands and operational costs for validators and Layer 2 networks.
Other proposals, such as EIPs 7825 and 7935, will adjust gas limits to improve efficiency and prepare the network for parallel execution, while EIPs 7939 and 7951 will increase performance and zero-knowledge proof support. These updates are designed to reduce transaction costs for users and developers while setting the stage for the next phase of cumulative scaling.

“The Ethereum 𝗛𝗼𝗼𝗱𝗶 𝗙𝗼𝗿𝗸 has been successfully completed and is now running smoothly on 𝗡𝗲𝘁𝗵𝗲𝗿𝗺𝗶𝗻𝗱 𝗖𝗹𝗶𝗲𝗻𝘁. Another smooth update, another key milestone on the road to Fusaka. Many thanks to everyone in the ecosystem who helped make this happen, from the customer teams to the researchers and operators.

Consensys too saying that Fusaka “paves the way for parallel execution” and lays the groundwork for future network advancements. The launch will be carried out in phases. Following the mainnet launch scheduled for December 3, the increase in blob capacity is expected on December 17, while a second fork to further expand blob capacity is scheduled for January 7, 2026.

Ethereum developers have already focused on the next update, dubbed “Glamsterdam,” which is expected to introduce faster block times and greater scalability improvements. Glamsterdam is included in the “Surge” stage of the network roadmap.
Meanwhile, the price of ETH remained largely unfazed by the technical development. The altcoin recorded a new drop of almost 3% in the last 24 hours and is currently trading below $4,000.
