Ironwood might present whether or not counterfeit ZEC existed
In a separate X publish, Shielded Labs mentioned Ironwood might produce proof about whether or not the Orchard bug was ever exploited, although the proposal doesn’t depend upon proving the problem retroactively.
If customers migrate from Orchard to Ironwood and no extra ZEC tries to go away the previous pool, that will be robust proof that the vulnerability was by no means exploited, Shielded Labs mentioned. If extra ZEC tries to go away, the turnstile would reject it, successfully stopping counterfeit cash from coming into the provision.
