The Gas fees on the Ethereum Mainnet have recently fallen to an outrageous low point—$0.02 per transaction, even cheaper than some Layer 2 solutions. But don't get it wrong, this isn't because the network is doomed; rather, it could be a calm period before a major event.

Tomorrow night Beijing time, Ethereum's most important upgrade since the "Merge", Fusaka, is about to go live. This is not a minor fix but a performance revolution for the entire network.

The core technology is called PeerDAS, which simply means that nodes verify data using "sampling checks" without each node needing to store all information. This frees up a huge space for Layer2. Coupled with the subsequent "micro-fork" mechanism to quickly increase the Blob capacity target, the transaction costs for Layer2 are expected to be further reduced by 40%-60%.

So now the Gas fees on the Mainnet, which are low to the ground, seem more like a technical cleanup before the upgrade. Once Fusaka is activated, Ethereum will transform into a highly efficient layer focused on settlement, pushing a large number of trading activities to be handled by cheaper Layer 2 ecosystems. Lower fees, faster speeds, and a smoother experience—once this flywheel effect starts turning, the possibilities become vast.

From the once "noble chain" to now striving to be a "popular infrastructure", can Ethereum finally shake off the historical burden of high Gas fees this time? When costs and speed are no longer bottlenecks, which track do you think will take off first: DeFi, GameFi, or NFT?
