Zcash bug hit shielded ZEC only, says Dragonfly's Qureshi

Frequently asked questions

1. Which Zcash holders were actually exposed to the bug?

   ▾

   According to Haseeb Qureshi, the bug would mainly have affected shielded ZEC holders, not transparent ZEC holders, because nearly all ZEC market liquidity is in transparent form.

2. How easy would it have been to cash out counterfeit shielded ZEC?

   ▾

   Qureshi argued it would have been difficult, since nearly all ZEC market liquidity sits in transparent ZEC and exchanges would not readily absorb large amounts of newly minted shielded ZEC.

3. What is the Zcash team doing to verify the shielded pool's integrity?

   ▾

   The Zcash team plans to introduce a new turnstile and a fresh shielded pool to confirm that the old pool was not inflated before the bug was patched.

4. Did shielded ZEC holders exit the pool after the disclosure?

   ▾

   Qureshi said the shielded pool's share of supply fell only from 31% to 30% over the past 48 hours, suggesting no mass exit in the immediate aftermath of the disclosure.

5. What is Haseeb Qureshi's personal exposure to Zcash and ZODL?

   ▾

   Qureshi disclosed that Dragonfly continues to hold ZEC and that he is personally an investor in ZODL, framing both as ongoing positions through the bug scare.
