Base

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)

What are your thoughts on past experiments in pumping the gas limit (let’s say Polyon in the early days, then BSC and others).

State growth is an issue for L1 because of the type of home users they target long before it’s an issue for professional infrastructure providers.

BSC yes, but I believe that’s more to do with rushed code changes to geth than the block limit.

I would expect syncing to rely more on snapshot for the L2 than it be a full sync from genesis.

I realise the architectures differ, but how is Arbitrum currently handling this?

Both BSC and Polygon are great examples of how NOT to push the limits, as they suffered bad chain halts and other issues, and both those chains are basically impossible for anyone to sync from scratch now.
