The next significant upgrade for Ethereum, Fusaka, has gone live on the Hoodi testnet, paving the way for its mainnet launch on December 3, which will introduce multiple improvements in scalability and security for the network.
“Another smooth upgrade, another important milestone on the path to Fusaka,” Nethermind reported on Tuesday after their widely utilized validator client completed the fork.
Fusaka will incorporate several Ethereum Improvement Proposals (EIPs), including Peer Data Availability Sampling, or PeerDAS, through EIP-7594, which allows validators to access smaller data segments on layer 2 networks rather than full blobs, enhancing node efficiency.
Also part of the update are EIP-7825 and EIP-7935, designed to raise the gas limit and increase efficiency as Ethereum gears up for parallel execution, enabling simultaneous processing of multiple smart contracts. Other EIPs aim to enhance zero-knowledge rollups.
This technical milestone comes amid significant leadership changes at the Ethereum Foundation recently, with several key contributors leaving and voicing concerns about the foundation’s strategic direction.
Meanwhile, Ether (ETH) has reached an all-time high this year, driven by increased investments in exchange-traded funds and a rise in corporate treasury adoption of the token.
Fusaka as a Three-Stage Process
The execution of Fusaka will occur in three stages: first, the mainnet launch; second, activation of the EIP that implements the blob capacity increase; and third, the implementation of the second blob capacity hard fork.

Following the implementation of Fusaka, focus will shift to the Glamsterdam upgrade, which is also part of the “Surge” stage in Ethereum’s technical roadmap aimed at enhancing scalability.
Fusaka Aims to Address Weaknesses in the Blockchain Trilemma
This upgrade aims to enhance Ethereum’s scalability, one of the three components of the “blockchain trilemma” introduced by Ethereum co-founder Vitalik Buterin, which also encompasses decentralization and security.
Ethereum was initially designed to prioritize decentralization and security over scalability, leading various competitor layer 1 blockchains, such as Solana and Sui, to emphasize scalability for faster transactions to compete with Ethereum.
The Fusaka hard fork occurs approximately six months after Ethereum’s previous major upgrade, Pectra, which concentrated on enhancements in staking performance and wallet usability for an improved user experience.
