Dragonfly’s Haseeb says fixed Zcash flaw was limited to privacy pool

Market fears around a recently fixed Zcash vulnerability overstate the practical risk, Dragonfly managing partner Haseeb said, arguing the flaw would only have let an attacker forge ZEC inside the shielded pool and that exploiting it before the patch was very unlikely. Any attempt to move those coins to mainstream exchanges would require unshielding them into transparent addresses, where any supply above Zcash's cap would be publicly visible and could be blocked, he said. Haseeb added that about 30% of ZEC remains in the shielded pool and only about 1% was unshielded after disclosure. He also said exchanges such as Binance and Coinbase mostly trade transparent ZEC, that Zcash plans a future upgrade with a new Turnstile mechanism and privacy pool, and disclosed that Dragonfly still holds ZEC while he is personally a ZODL investor.
