The biggest challenge ZEC is facing right now is being stuck in a 'can't explain clearly' dilemma: 1) They can't clearly explain whether the Orchard privacy pool has actually been 'hacked' over the past four years, or even prove whether this is a carefully designed 'infinite mint' backdoor by their own team; 2) Assuming it was indeed 'attacked,' they can't clearly explain how hackers in the Orchard pool double-spent ZEC to steal real value. If the total supply check via Turnstile wasn't triggered, it means the damage could only happen quietly, bit by bit—using fake ZEC to slowly purchase real-world goods like merchant services, VPNs, and gift cards. This kind of hidden damage isn't as obvious as massive token theft, but it essentially drains the value that all ZEC holders should rightfully enjoy; 3) Even if Shielded Labs is about to release a new upgrade with a new privacy pool and enhanced Turnstile accounting and mathematical proofs, it can only prove that the current effective supply in the Orchard pool is less than the total amount that entered the pool. It still can't guarantee that there won't be potential vulnerabilities discovered in the future, because there's an inherent conflict between verifiable supply and the privacy black box. This directly undermines the trust Zcash has built in the privacy services market over the years—'privacy' itself isn't the issue, but 'verifiable supply' has become ZEC's Achilles' heel.
