ZEC: Privacy Bug Sparks 50% Crash, $5B Wipeout

ZEC plunged more than 50% in 24 hours, erasing $5 billion in market value after disclosure of a critical flaw in the Orchard privacy pool that went undetected since May 2022.

Flaw Details and Market Reaction

Security researcher Taylor Hornby leveraged Claude Opus 4.8 to craft a working proof-of-concept that minted fake ZEC in local tests on May 29. The bug was patched June 2, yet Zcash privacy architecture prevents any audit confirming whether counterfeit coins entered circulation beforehand, unlike Bitcoin's transparent supply. Shielded Labs now explores a network upgrade for verifiable supply integrity while the team denies any exploitation occurred.

ZEC trades at $314.66, sitting below the lower Bollinger Band support at $350.85 amid a bearish trend where EMA50 resistance holds at $540.67 and EMA200 at $520.55. RSI(14) at 19.27 signals deep oversold conditions while MACD(12,26) prints -48.88 on a confirmed death cross, indicating sustained downside pressure that aligns with the post-bug liquidation wave. Traders now watch for any bounce off current levels before further tests lower.

Long-term holders reference past ZEC price prediction models that assumed flawless privacy, now facing revision after this event. The episode underscores how single-point design risks can accelerate crypto market crash dynamics even in established privacy assets.
