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

FAQs
Fusaka improves Ethereum by fixing blob fees and introducing PeerDAS, making L2 scaling more efficient and the network more stable.
Your L2 fees won’t spike. The upgrade stops an unsustainable subsidy where blobs cost almost nothing. It introduces a small, stable fee range to ensure the network’s long-term health and predictable, low costs.
By increasing blob space and using PeerDAS, Fusaka allows more L2 data, prepares the network for apps, and strengthens Ethereum’s core.
