Since its launch, Ethereum (ETH) has undergone a series of upgrades to improve security, scalability, and sustainability. Since 2020, Ethereum has made five major upgrades to transition to proof-of-stake, including the Merge, Shapella, and EIP-1559. In the latest development, network developers have set their sights on the Fusaka mainnet upgrade.
### Fusaka Mainnet Launch Scheduled for December
In a significant and decisive move, Ethereum developers have locked in December as the mainnet launch date for the Fusaka upgrade. During the All Core Developers Consensus (ACDC) call on October 30th, the team finalized the date following Fusaka’s successful deployment on the Hoodi testnet on October 28th.
In early October, the highly anticipated Fusaka upgrade was also successfully deployed on the Holesky and Sepolia testnets. Each rollout was closely monitored to assess validator stability, synchronization, and overall performance, paving the way for a full mainnet launch.
Following its release, Fusaka will introduce a dozen Ethereum Improvement Proposals (EIPs) aimed at enhancing the network’s efficiency, speed, and security. This marks Ethereum’s most significant upgrade since the Pectra update in May 2025 and sets the stage for the next phase of layer-2 integration.
### Key Features and Anticipated Developments
The Fusaka upgrade includes several new features that distinguish it from previous updates:
– **Peer Data Availability Sampling (PeerDAS):**
This central feature helps validators access and verify data more effectively. PeerDAS was originally slated for the Pectra upgrade but was delayed to allow for more thorough testing.
– **Block Gas Limit Increase:**
Fusaka raises the block gas limit from 30 million to 150 million units. This fivefold increase will enhance Ethereum’s transaction capacity and double the throughput of blob data.
With these upgrades, the core development team hopes to push Ethereum closer to its primary goals of low-cost scalability and high throughput.
### How’s the ETH Market Doing?
Interestingly, even after announcing the long-awaited Fusaka upgrade, Ethereum’s market structure remains weak, with bearish forces dominating.
After breaching the $3,800 support level, ETH dropped to a low of $3,600 before rebounding to a high of $3,873. At press time, Ethereum was trading at $3,842, down 1.72% on the daily charts.
This decline has been primarily driven by increased selling pressure. According to CryptoQuant data, Ethereum Exchange Netflow has remained positive for the past two days. Typically, heightened selling activity exerts strong downward pressure, often signaling further price drops.
As a result, ETH fell below its short-term exponential moving averages (EMAs). Simultaneously, its Sequential Pattern Strength declined to -9.33, indicating the emergence of a pattern marked by progressively lower highs.
These market conditions suggest an exhausted uptrend with the potential for a short-term downside move. If prevailing conditions persist, ETH is likely to breach $3,800 and find support at the 200 EMA around $3,601.
Conversely, if the recent drop creates a buying opportunity, bulls will aim to test the 50 and 100 EMAs at $3,988 and $4,089, respectively.
