Ethereum Research: Transaction Admission Should Distinguish "Order Dependence" Rather Than State Read Volume

Odaily News: The latest research from Ethereum Research proposes that in the context of framed transactions and account abstraction, the core distinguishing dimension for transaction admission rules should be whether the validation logic depends on the order of transactions within a block, rather than the "volume of state reads." The article categorizes transactions into three types: single-writer state, shared state that can accept stale state roots, and competing state that must read real-time values. It argues that several existing mechanisms are essentially setting different thresholds around this dimension. The author further points out that only "exactly-once" type assertions (such as whether a nullifier has already been used, or whether a slot is still vacant) inherently require full-order coordination and cannot completely eliminate order dependence through purely proof-based admission.
