Ethereum Regains $3,000 as Fusaka Upgrade Looms

With the Fusaka upgrade set to go live next week, the timing is pivotal. Ethereum is entering a critical phase for scalability and economic alignment, moving to address the distortions introduced by Dencun and restore balanced settlement incentives just as market pressures ease.

Blobs and the data bottleneck

Ethereum currently targets six blobs per block, a level maintained since late summer. This capacity has functioned as a reliable data-availability layer as L2 throughput accelerated. To date, rollups have posted over 14mn blobs, amounting to 1.67TB of transaction data. According to Blobscan, this system has saved L2s 60,500 ETH in fees compared to pre-Dencun calldata costs.

Demand, however, is rising. Blobspace consumption has grown 165% year-over-year, driven by an expanding roster of L2s. Base alone accounts for nearly 50% of all blobs posted, underscoring how concentrated Ethereum’s scaling environment has become.

Fusaka: Ethereum’s Next Scaling Milestone

This accelerating demand is why Fusaka matters. The upgrade targets the data-availability layer supporting rollup throughput. The integration of three new core EIPs lays the groundwork for Ethereum to scale safely toward 128 blobs per block, a twentyfold increase in capacity.

One of the most vital aspects of Fusaka is its response to the economic distortions introduced by Dencun. Critics have argued that Dencun’s aggressive fee compression pushed L2 settlement costs effectively to zero, weakening ETH’s deflationary profile. Post-Dencun, rollups shifted from calldata to blobs, cutting L1 costs by over 90% and nearly eliminating L2-driven burn.

Fusaka addresses this. Rather than reinventing fees, it corrects the over-subsidization. EIP-7918 anchors blob pricing to L1 execution costs, ensuring rollups pay a fair, market-reflective rate. As a result, L2 activity, now the dominant source of throughput, will once again exert upward pressure on base fees.

The Ethereum's Fundamental Snapshot

Ethereum’s fundamentals continue to strengthen, reinforcing its position as the settlement layer for global onchain finance.

The network remains the leader in distributed real-world assets (RWA), securing $11.93bn of the sector’s $18.56bn Total Value Locked (TVL), roughly 64% of tokenized assets. Including stablecoins, the gap widens. Ethereum now supports $181.3bn in stablecoins out of a global circulating base of $298.8bn, growing 45.3% year-to-date.

DeFi TVL has also surged, stabilizing at an 18.3% increase YTD ($330.7bn versus $279.7bn). Core economic engines drive this rebound: stablecoin issuers (Tether, Circle), lending (Aave, Spark, Sky), and liquid staking and restaking (Lido, Ether.fi, EigenLayer). These three pillars account for over 80% of Ethereum TVL.

While fee levels sit near historical lows, Ethereum’s economic output (“chain GDP”) is accelerating. Quarterly GDP is up 36% QoQ, setting a new all-time high and pushing cumulative GDP toward the $30bn mark, up 79% since 2024.

The divergence between falling fees and rising economic activity is a direct consequence of Dencun. Fees capture what users pay for L1 blockspace, which collapsed following the introduction of blobs. GDP measures the economic value generated on top of Ethereum.

The picture is clear: Ethereum is handling more economic value than ever, even as blockspace becomes cheaper. Unlike Solana, where GDP has halved over the past two quarters as speculative flows faded, Ethereum’s DEX volumes remain near prior-cycle highs.

The app-chain era

A new wave of L2 application chains is entering the landscape. These purpose-built rollups are entirely Ethereum DA-native. Lighter, a high-throughput ZK-rollup launched in October, has already become the fourth-largest rollup by total value secured. Its release drove Ethereum ecosystem transactions per second (TPS) and blob usage to all-time highs according to L2BEAT, demonstrating how app-chains can amplify the underlying economic feedback loop.

As Coinbase, Robinhood, and Kraken commit to the rollup model, Ethereum’s path is set. L2s now absorb high-frequency activity, freeing the base layer for institutional settlement.
