Ethereum’s upcoming major upgrade, Fusaka, set to launch on December 3, 2025, is anticipated to significantly reduce scaling costs and enhance the overall efficiency of the network, which could bolster ETH’s current bullish trajectory. This timeline was confirmed following successful testnet deployments on Holesky, Sepolia, and Hoodi earlier this fall.
### Key Features of the Fusaka Upgrade
A central component of the upgrade is PeerDAS (EIP-7594), a feature that allows nodes to verify only segments of blob data instead of downloading whole content files. This adjustment not only streamlines network operations but also lays the groundwork for the future implementation of full danksharding. Along with PeerDAS, developers will introduce two Blob Parameter Only (BPO) forks aimed at incrementally increasing blob capacity without requiring new client software. Specifically, BPO-1 will raise the blob target from an initial 6/9 to 10/15 one week after Fusaka’s activation, followed by BPO-2, which will increase it further to 14/21 a week later—effectively more than doubling capacity.
The introduction of blobs during the Dencun upgrade has already seen significant uptake, with high demand from Layer-2 (L2) networks like Arbitrum and Unichain. With reduced costs associated with L2 submissions, increased on-chain activity is expected, creating a feedback loop that enhances demand for ETH, particularly as gas fees and staking rewards are linked to network usage.
In the medium term, the increase in data capacity is poised to strengthen Ethereum’s position as the primary settlement layer for decentralized finance (DeFi).
### Market Response
As Fusaka approaches, Ethereum is currently experiencing bullish market conditions, with some analysts projecting that ETH could reach the $6,000 mark by October if this momentum persists. The upgrade comes at a critical juncture, enhancing Ethereum’s role in the DeFi ecosystem, where $132 billion in deposits currently reside—significantly more than its nearest competitor, Solana.
Insights shared by researcher Christine D. Kim following the latest All Core Devs Consensus (ACDC) call indicate that the upgrade’s implications go beyond mere technical improvements; it’s viewed as a transformative step for scalability, security, and the overall health of the ETH ecosystem.
### Network Usage Trends
Recent charts highlight a steady increase in blob transactions from March 2024 to September 2025, showcasing a notable surge in daily activity that surpassed 200,000 entries mid-2025. Notably, Arbitrum One and Unichain have led in terms of utilization, underscoring Ethereum’s vital role as a data availability layer as scaling solutions evolve to facilitate cheaper transaction fees.
The average daily blob counts from September 14-18, 2025, appeared stable, averaging between 1,000 and 1,500. Dominance was observed from ZERO Network and Unichain, with several other networks maintaining a consistent presence.
### Price Predictions
Technical analysts are observing bullish patterns suggesting a potential breakout for Ethereum, with a symmetrical triangle formation indicating that it may rise approximately 30% from current levels—entirely plausible if ETH continues its upward trajectory. As of the latest reports, Ethereum’s trading price stands at $4,460, having declined by 2.79% over the last 24 hours.
The upcoming Fusaka upgrade is set to establish an important milestone for Ethereum, positioning it favorably within the competitive landscape of blockchain networks and solidifying its role as a foundational layer for decentralized finance.
