Something major is about to happen in the Ethereum ecosystem. The long-awaited Fusaka upgrade is set to go live on December 3, and expectations are already running high across the market. According to Bull Theory, one of the analysts closely tracking Ethereum, this upgrade could redefine how Ethereum handles transactions, Layer 2 scaling, and overall network efficiency.
The Fusaka upgrade represents a technical leap designed to solve Ethereum’s most persistent problem: scalability. The network’s current capacity of 45 million gas is set to expand dramatically to 150 million, allowing it to process more transactions at once. This means less congestion, faster confirmations, and potentially lower gas fees for users and developers building on the network.
ETHEREUM MASSIVE UPGRADE IS COMING NEXT MONTH.

On December 3rd, Ethereum’s Fusaka Upgrade will go live.
It’s one of the biggest upgrades and will completely change how Ethereum handles transactions, Layer 2s, and overall network speed.

What Makes the Fusaka Upgrade Different
Fusaka introduces two groundbreaking components: PeerDAS and Verkle Trees. PeerDAS, short for Peer Data Availability Sampling, allows Ethereum to process Layer 2 transactions more efficiently. Instead of requiring every node to download entire data sets, it enables them to verify smaller samples. This method significantly reduces computational load and speeds up verification.
Verkle Trees, on the other hand, are designed to make blockchain storage lighter and more efficient. They simplify how nodes verify data, making the entire system faster and easier to maintain.
Together, these innovations aim to reduce costs, boost transaction speed, and improve Ethereum’s ability to handle increased activity across decentralized finance (DeFi), NFTs, and other blockchain applications.
Why Fusaka Could Strengthen Ethereum’s Economic Foundation
Every major Layer 2 chain such as Arbitrum, Base, and Optimism relies on Ethereum for settlement. By reducing verification complexity, Fusaka lowers the operational costs of these Layer 2s. This makes it cheaper for users to transact and for developers to deploy applications.
When activity on Layer 2s grows, Ethereum benefits directly because every transaction settled on these chains still consumes ETH for gas fees.
As more rollups and decentralized applications become affordable to operate, demand for ETH naturally increases. The upgrade therefore strengthens Ethereum’s position as the foundational settlement layer for the entire crypto economy.
Ethereum Price Reaction to Previous Upgrades
Ethereum has a history of reacting strongly to major upgrades. When the Pectra upgrade launched, ETH rallied by nearly 50% in just a week. That upgrade focused on network efficiency, while Fusaka goes even deeper by addressing both scalability and cost reduction. The last time Ethereum saw such structural improvements, it led to renewed confidence and higher market participation.
Fusaka could trigger a similar or even larger move because it makes Ethereum more economically efficient. While The Merge made Ethereum energy efficient by transitioning it to proof-of-stake, Fusaka enhances its economic sustainability, which is key to long-term growth.
Ethereum Price Outlook Remains Mixed
Technical readings from Investing.com suggest that Ethereum’s current outlook on the weekly chart still leans slightly bearish despite growing optimism around the upgrade. The table below summarizes the current indicators and what they imply for ETH price trends.
| Name | Value | Interpretation |
|---|---|---|
| RSI(14) | 49.059 | Neutral momentum suggesting indecision in market direction |
| STOCHRSI(14) | 6.329 | Oversold condition pointing to a potential near-term rebound |
| MACD(12,26) | 143.56 | Buy signal indicating possible short-term upward movement |
| Ultimate Oscillator | 43.995 | Slightly weak buying pressure hinting at caution |
| ROC | -17.063 | Negative momentum indicating reduced market strength |
| Bull/Bear Power(13) | -555.867 | Bearish sentiment reflecting stronger selling pressure |
The indicators show that although Ethereum price remains under pressure, oversold conditions may create room for a short-term rebound. The overall structure, however, still lacks strong bullish confirmation until a clear breakout occurs.
Can the ETH Upgrade Trigger an Altcoin Season?
The Ethereum price remains bearish for now, but if the Fusaka upgrade triggers a rally similar to Pectra’s, a 50% surge could push ETH beyond the $5,000 mark. A move above this level would represent a major technical breakout and could restore market confidence.
Such a scenario might also reignite the broader altcoin market. Historically, whenever Ethereum gains momentum, other cryptocurrencies tend to follow. This correlation has been a consistent feature of past bull runs, with Ethereum often leading the first wave of rallies that lift the rest of the market.

If Fusaka successfully delivers faster transactions, lower fees, and smoother Layer 2 interactions, it could mark the beginning of a new growth phase for both Ethereum and the wider crypto ecosystem. A climb toward $10,000 would likely confirm that the next altcoin season has begun.
The coming weeks will reveal whether this upgrade becomes another turning point in Ethereum’s long journey toward mass adoption.
