One of the most outrageous failures in the history of privacy tech just got confirmed.
Zcash has experienced one of its biggest selloffs in recent memory as a result of investors' widespread concern over a critical Orchard pool vulnerability. One of the worst sell-offs in history In a single session, the asset fell more than 40%, wiping out weeks' worth of gains as traders hurried to reevaluate the network's risk profile.
Confirmation that a bug affecting the Orchard shielded pool existed from May 2022 until it was fixed on June 1 is the source of the controversy. Discussions within the Zcash community indicate that the vulnerability might have made it possible to create counterfeit ZEC, which would have been very challenging to identify due to the pool's privacy-preserving features.
For many investors, the problem is fundamental to Zcash's value proposition. Cryptographic guarantees are crucial to privacy systems, and supply integrity uncertainty naturally raises concerns. That reality is reflected in the market's response.
