Regarding Base transaction fees: they are high because the chain is at its target capacity (2x the throughput of the L1), but demand has increased dramatically. Data fees remain insignificant thanks to EIP-4844 blobs which are still far from capacity!  So while "it could be worse..." what can make it better? (cont)

Simplest thing would be to just increase the chain's target capacity. I'm pretty confident we could just 2X it right now and the Base sequencer + most node infra would handle it just fine. But "pretty confident" isn't good enough. And it's not just the short term we need to be concerned about. (cont)

Longer term, increasing throughput leads to faster rate of state growth. While Ethereum roadmap has some cool ideas for dealing with state growth, they are not going to be ready in the short term. We need to keep overall growth aligned with the timeline for these sorts of features. (cont)

On the bright side, overall L2 capacity is well below target (based on the fact that blobs are under-utilized). So Ethereum *as a whole* will continue scaling by traffic growth on other underutilized L2 rollups and/or new L2s coming online. Chain interop remains a UX sore point, but solutions to this are also underway.

Oh, and as for whether this is a new normal or a temporary spike in fees, it's tough to say. My guess is there's a temporary frenzy going on and fees could drop precipitously in the coming days, but the longer term trend in demand will continue to be up and to the right, so gotta get scaling anyway!

That said, we will be evaluating bumping up the target conservatively in the near term if we reach confidence this can be done safely from an infrastructure perspective, and we conclude it keeps us aligned with the longer term solutions to state growth. (cont)

State is the state of all accounts on the L2.  Blobs store transaction history -- while it's good to expire that too, you can't discard, say, the balances of certain ERC20 tokens. And over time, as more and more people hold tokens, that kind of state only gets bigger.

Maybe this is my misunderstanding but I thought blob storage expired? How does increasing throughput increase general state growth?
