Ethereum’s next major update, Fusaka, is now live on the blockchain’s latest testnet, Hoodi, setting the stage for the December 3 mainnet launch that is expected to add several scalability and security improvements to the network.
“Another smooth update, another key milestone on the road to Fusaka,” Nethermind he said in a post to X on Tuesday after the widely used validator client completed its fork.
Fusaka will add several Ethereum Improvement Proposals (EIPs), such as Peer Data Availability Sampling, or PeerDAS, via EIP-7594, allowing validators to read smaller pieces of data on Layer 2 networks as opposed to full blobs, improving node performance.
The update also includes EIP-7825 and EIP-7935, which aim to raise the gas limit and improve performance as Ethereum prepares to unlock parallel execution, which is the processing of multiple clever contracts at the same time. Other EIPs in the update focus on improving zero-knowledge rollups.
This technical milestone comes amid major changes in the Ethereum Foundation’s leadership in recent months, with several key contributors leaving and criticizing the foundation’s direction in steering the network.
Meanwhile, Ether (ETH) has hit an all-time high this year on rising inflows into exchange-traded funds and increased adoption of the token by corporate treasuries.
Fusaka is a three-part process
The execution of Fusaka will take place in three stages: first, the actual launch of the mainnet; secondly, an EIP will be launched implementing an augment in blob capacity; and third, the second blob capacity demanding fork will go into effect.

Once Fusaka is deployed, attention will shift to the Glamsterdam upgrade, which is also part of the “Surge” stage of Ethereum’s technical roadmap aimed at making it more scalable.
Fusaka aims to tune the faint point in the blockchain trilemma
The update aims to improve Ethereum’s scalability, which is one-third of the so-called “blockchain trilemma” coined by Ethereum co-founder Vitalik Buterin, which also includes decentralization and security.
Ethereum was designed to prioritize decentralization and security over scalability, and several competing Layer 1 blockchains, including Solana and Sui, have focused on scalability to offer faster transactions and compete with Ethereum.
Fusaka’s demanding fork comes about six months after Ethereum’s last major update, Pectra, which focused on performance and wallet features to improve the user interface and user experience.
