It leaves no residual footprint on the network\u2019s state. Critically, the proposal does not replace Ethereum\u2019s existing account model; smart contract activity would continue operating exactly as it does today.<\/p>\n<p>This is a targeted patch for a specific scalability problem, not a wholesale architectural shift.
