Ethereum’s next major network upgrade, Fusaka, is coming next week and is scheduled for a December 3 release. The upgrade will highlight the chain’s ability to scale for global demand without compromising decentralisation or permissionless access. It introduces changes affecting users, rollups, node operators, and enterprises.
Fusaka aims to improve the everyday Ethereum experience, bringing the network closer to mainstream consumer-app usability. Data-scaling improvements are expected to support near-instant transactions, while mobile-ready wallets will be able to integrate cheaper passkey support for secure logins using on-device hardware.
A key component of the upgrade, PeerDAS (EIP-7594), will enable data sampling, unlocking up to an eightfold increase in data throughput. The enhancement is designed to reduce blob fees for rollups, create more capacity for growth, and ultimately lower transaction costs for end users.
Fusaka expands Ethereum’s capacity while aiming to keep node operations sustainable. The block gas limit will increase from roughly 45 million to 60 million, raising throughput. At the same time, history expiry is being introduced to support lighter and more affordable nodes over the long term. Operators running “super nodes”, validators holding 4,096 ETH or more, will need to meet updated bandwidth requirements.
Vitalik Buterin recently explained that the Ethereum blockchain network will see a 5x jump in gas limit by 2026. Thus, each Ethereum block will handle a significantly larger volume of transactions, on-chain activity, and contract executions. Buterin also noted that the proposed gas limit increase will support resource-intensive operations for nodes, such as creating new storage slots with SSTORE and similar state-modifying actions.
The Fusaka upgrade introduces features intended to ease enterprise adoption. Native support for the secp256r1 cryptographic curve aligns Ethereum with widely used corporate security standards, while adjustments to blob base-fee mechanics aim to make transaction fees more predictable for institutional integrations.
Fusaka marks Ethereum’s second major upgrade of the year, continuing a consistent development cadence delivered openly and without network downtime. Ahead of the upgrade, the ETH price has been showing some momentum, regaining the $3,000 level.
Crypto analyst Ted Pillows stated that ETH momentum has weakened in recent times. Pillows warned that if ETH fails to maintain this support zone, the price could fall below $2,800.
