Pretty sure this was discarded years ago in the annals of Ethereum L1 design, but have we totally given up on allowing a tx to only lock part of the state trie, and pay for how much each locks?
It’s crazy to me that every tx gets a global lock by default. Being familiar with a UTXO model, I remember I was shocked. No wonder gas is high — you should have to pay out the nose for that privilege.
Paying for the scope of a tx’s state lock would open up more parallelizable verification, etc, but it’d also be more fair to folks who are just pushing tokens around and are only touching a single contract.
It’d also be satisfying to see our flash loan arb friends pay for the superpower.
there’s some movement in this direction with eip 2930. But it’s not sufficient. Stateless eth had some shakeups lately and I wouldn’t count on it being a thing for several years
