Fusaka Upgrade Set to Go Live Today: What to Expect for Ethereum’s Network and Price

• Ethereum’s Fusaka upgrade goes live at 21:49 UTC, improving network infrastructure.
• New features like PeerDAS and BPO increase Layer-2 throughput, potentially lowering transaction costs.
• ETH trades around $3,060 with key support at $2,950 and resistance near $3,100–$3,250.

Ethereum is entering the final phase before its next major network upgrade, with the Fusaka upgrade scheduled to go live at 21:49 UTC, according to the official countdown displayed on Ethereum.org. The upgrade will activate later today once the blockchain reaches its predetermined slot, marking one of the most significant infrastructure improvements to the network this year.

Fusaka combines two major protocol-level improvements — merging an execution-layer update (“Osaka”) with consensus-layer enhancements (“Fulu”). The most important technical change is the implementation of Peer Data Availability Sampling (PeerDAS) (EIP-7594) along with “Blob Parameter Only” (BPO) upgrades. This lets network nodes store only a fraction of “blob data” while still ensuring network security — dramatically reducing storage/bandwidth burdens.

In practical terms, this means much-improved scalability for Layer-2 rollups: Ethereum can now support significantly higher transaction/data throughput, potentially lowering transaction costs and enabling more users and applications to run efficiently.

The upcoming deployment has sparked comparisons to Ethereum’s Pectra upgrade earlier this year, which delivered execution-layer improvements and preceded a noticeable recovery in Ethereum’s market performance.

What Happened with Pectra?

Earlier in 2025 — on May 7 — Ethereum completed a major upgrade called Pectra. Pectra delivered several important changes: increased staking-validator limits, enhanced wallet-usability features (e.g. account abstraction via EIP-7702), and boosted Layer-2 data capacity via more blobs per block. Also, the market reaction was strong — ETH surged ~20-29% soon after the upgrade as confidence returned. That rally helped restore bullish sentiment around Ethereum’s long-term potential, drawing interest from both developers and investors. 

ETH 24-H Market Outlook

At the time of writing, Ethereum is trading around $3,060 with a market capitalization of approximately $370 billion and a 24-hour trading volume near $30 billion. The technical outlook shows cautious optimism: the Relative Strength Index (RSI) sits at 62, indicating mild bullish momentum without reaching overbought territory. The Moving Average Convergence Divergence (MACD) has recently seen a bullish crossover on the daily chart, signaling potential upward momentum. 

Looking ahead, the key moving averages support the current price, with the 50-day moving average near $2,970 acting as immediate support, and the 200-day moving average around $2,850 providing a stronger long-term floor. Resistance levels are noted at $3,100 and $3,250, where sellers may take profits, while support zones at $2,950 and $2,800 could prevent deeper pullbacks.

What to Expect Post-Fusaka Activation

With the upgrade about to go live, market participants are watching closely for how Ethereum’s price and network activity respond. Given the nature of Fusaka as a scalability and infrastructure-focused upgrade, any significant price impact may take time to materialize, depending on Layer-2 adoption and broader market conditions.

However, if Fusaka enables more efficient rollup throughput and reduces transaction costs as anticipated, it could strengthen Ethereum’s position as the leading smart contract platform and support further price appreciation over time.
