According to CoinMeta, the latest research published by wublockchain12 indicates that in the scenarios of frame, transaction, and account abstraction, what truly needs to be distinguished in transaction access rules is not "how much state has been read," but whether the verification logic depends on the transaction order within the block. The article categorizes these into three types: single-writer states, shared states where old state roots are acceptable, and competitive states where real-time values must be read. It is argued that many existing mechanisms essentially set different thresholds around this dimension. The author further points out that assertions of a "precisely once" nature, such as whether a certain nullifier has been used or whether a slot is still available, naturally require total-order coordination and cannot be completely eliminated through purely proof-based access control.
