Better State Diff Format #711

Closed ercecan closed 1 month ago

eyusufatik commented 4 months ago

Currently we are accumulating (Vec, Option<Vec>) for state diffs.

One optimisation is to get rid of vectors and just depending on key hashes #712 .

Since nonce's in EVM increase by one (%99 of the time) it can be really helpful to get rid of u256 updates for nonces on the diff. this is done by zksync afaik. however, since we maintain a more generic tree rather than ethereum's state, it might be hard to idenitfy which keys are nonces :)

Let's discuss potential improvements to the state diff formats in this issue.
