I love this EIP! 😄
I think in general the idea here is that we only charge the cold gas cost once, and this is used to reflect when we pull this storage from disk. If that is the case, then I also propose we remove the logic from 2929 which reverts the journal of warm slots in case a sub-call reverts. This would make the implementation of 2929 for this fork likely much easier (since the revert mechanism does not have to be coded) and we thus now have that cold load costs for an account/slot are at most only charged once per blob.

The commit df49e2c (as a parent of 0c66ba4) contains errors. |

how different is this from https://eips.ethereum.org/EIPS/eip-3584 ? if not much can we revive the same EIP? |
I think they are different enough to keep separate. 3584 is more to share the access list mechanism over the block while this EIP is about doing this without using access lists though a first-access-pays mechanism + no arguments in the header. I can see a realistic world with both of those EIPs being shipped. |
This EIP proposes to keep accessed addresses and storage keys warm over the duration of a block.
