Ironwood might present whether or not counterfeit ZEC existed
In a separate X put up, Shielded Labs stated Ironwood could produce proof about whether or not the Orchard bug was ever exploited, although the proposal doesn’t rely on proving the difficulty retroactively.
If customers migrate from Orchard to Ironwood and no extra ZEC tries to go away the previous pool, that might be sturdy proof that the vulnerability was by no means exploited, Shielded Labs stated. If extra ZEC tries to go away, the turnstile would reject it, successfully stopping counterfeit cash from getting into the provision.
