Ethereum’s upcoming Fusaka upgrade is scheduled to go live on December 3. The date was confirmed a few days ago, following successful deployments on the Holesky, Sepolia, and Hoodi testnets. While the upgrade has already been widely discussed among developers, many are now asking a more pressing question: can it help turn Ethereum’s price around?
Over the past month, ETH has dropped from over $4000 to just above $3100. The correction has erased months of gains and left traders watching for any catalyst that might signal a reversal. One potential turning point is Fusaka – an upgrade that brings technical improvements aimed at scalability and efficiency.
PeerDAS and Data Efficiency
The central feature of Fusaka is Peer Data Availability Sampling (PeerDAS). It allows validators to verify data without downloading full datasets, helping reduce network strain and lowering hardware requirements for node operators.
This change also benefits Layer-2 rollups, which rely on Ethereum for data availability. By improving how blobs (temporary data packages) are handled, PeerDAS could reduce costs and increase throughput for rollup-based applications.
Fusaka’s rollout includes support for this system and lays the foundation for future steps, such as increasing blob capacity through scheduled follow-up forks.
Increased Block Capacity
Fusaka will also increase Ethereum’s block gas limit from 30 million to 150 million units. This adjustment allows more transactions per block and may ease congestion during high activity periods.
Alongside PeerDAS, the upgrade introduces several Ethereum Improvement Proposals (EIPs) focused on performance, security, and long-term network scalability. While these changes are largely backend-focused, their combined impact could influence developer activity and user experience over time.

Comparisons to Pectra
The previous upgrade, Pectra, went live in May 2025. At the time, Ethereum was trading near $1800 after a long bearish stretch. Within days of the upgrade, ETH had climbed to $2500, and in the following months surged to a new all-time high.
That historical context is one reason why Fusaka is being closely watched. While the technical changes are different, the timing is similar – and so is the market sentiment.

Outlook Ahead of the Launch
The Ethereum Foundation has also launched a bug bounty program with rewards up to $2 million, aiming to identify vulnerabilities before the mainnet rollout. This signals confidence from developers that Fusaka is ready, and that the upgrade process is expected to go smoothly.
Whether it will have an immediate effect on price remains uncertain. But with ETH under pressure and recent performance lagging behind broader market movements, expectations are growing. Fusaka may not guarantee a trend reversal – but for Ethereum, the timing could hardly be more critical.
