Ethereum News Today: Fusaka Upgrade Slashes Blob Gas Fees - Major Network Change Live

Gas just got cheaper. The Fusaka upgrade is now live on Ethereum, delivering a long-awaited overhaul to how the network handles data—and more importantly, what it costs.

What Changed with Blob Gas?

Fusaka fundamentally retools the fee market for data blobs, those dedicated data packets introduced with Dencun. The mechanism that dynamically adjusted blob gas prices based on demand? It's been replaced. The new system introduces a fixed, predictable pricing model designed to eliminate the wild fee spikes that could make layer-2 transactions briefly more expensive than using Ethereum directly. It's a direct fix for a pain point that had developers and users alike gritting their teeth.

Why This Matters for Builders and Users

For the ecosystem, this isn't just a minor tweak—it's a stability play. Predictable costs mean layer-2 networks can offer consistently low fees without surprise surcharges. That reliability is rocket fuel for adoption, making Ethereum's scaling narrative stronger and more user-friendly. Apps built on rollups get a smoother runway, and end-users spend less time worrying about transaction costs and more time actually using decentralized applications.

The Bigger Picture: Ethereum's Scaling Trajectory

Fusaka isn't a standalone event; it's the next logical step in the rollup-centric roadmap. By cementing cheap, reliable data availability, Ethereum reinforces its position as the foundational settlement layer. Other chains might boast lower fees, but they're trading decentralization for that speed—a classic case of 'you get what you pay for, and sometimes you don't even get that.' This upgrade sharpens Ethereum's competitive edge, proving it can evolve its core economics without compromising security.

The bottom line? The upgrade works. Blob fees are down, predictability is up, and the network continues its methodical march toward scalable, sustainable throughput. For the crypto finance crowd always chasing the next shiny object, this is a reminder: sometimes the most bullish move isn't a new token, but a core network getting its act together.

Ethereum’s new Fusaka upgrade has delivered an important fix that many users did not even realize was needed. The upgrade changes how blob fees work, and it ends a problem that kept blob costs NEAR zero for months. Since the Dencun update, the blob base fee has been stuck at 1 wei, which is almost nothing. 

Rollups were using the ethereum data space for free, and the protocol had no real fee market. Fusaka fixes this by raising the minimum blob price to match the actual verification cost. This looks like a jump of millions of times, but in reality, users were paying almost zero before, so L2 fees will not suddenly spike.

Ethereum Blob Gas Fee Changes Explained

Developers introduced EIP-7918 to set a fair floor price for blobs. The old fee was too low and caused an imbalance. With the new rule, blob fees now MOVE in a range between 0.01 Gwei and 0.5 Gwei. This restores normal pricing and stops the network from subsidizing rollups. 

More upgrades are coming soon. On December 9, the blob target will increase from six to ten. On January 7, it will rise again from ten to fourteen. This gives rollups more space to post data and helps keep L2 fees stable.

PeerDAS Brings Real Ethereum Scaling

The most important part of Fusaka is PeerDAS. It allows nodes to check only small samples of data instead of downloading everything. This reduces the load on node operators and increases the amount of data Ethereum can handle. 

It is the first real step toward Ethereum’s long-term scaling plan. The network still needs more upgrades in areas like block building and mempool design, but Fusaka moves Ethereum in the right direction. It gives L2 networks more room to grow and prepares the chain for new apps, from AI agents to on-chain games.

Fusaka is not a very big upgrade, but it strengthens Ethereum at the core. Users may not notice the change right away, but developers will build better apps because of it. Ethereum now has a more stable fee system and a stronger base for the next wave of growth
