About this episode

The episode discusses a critical bug in Zcash that could have minted unlimited counterfeit ZEC and its implications for the market.

A critical bug in Zcash's Orchard shielded pool could have minted unlimited counterfeit ZEC — and it sat there for 4 years. The price has lost ~47% in three days. David walks through what happened, why ZK trust keeps mattering, and what it means for holders. Plus: Polymarket's UMA ruling that Strategy didn't sell Bitcoin (it did), and the end of the Bitcoin ETF outflow streak.
