Odaily Planet Daily reported that Taylor Hornby discovered a critical counterfeiting vulnerability in the Orchard pool of Zcash on May 29, 2026. Taylor Hornby reported the vulnerability to the Zcash Open Development Lab, and the parties cooperated to complete the fix on June 2. The vulnerability could have been exploited to secretly create an unlimited number of counterfeit ZEC within the Zcash Orchard. Due to the privacy features of Orchard, it is cryptographically impossible to prove whether the vulnerability was exploited before the fix was deployed.

The vulnerability had existed since the activation of Orchard in May 2022 until the emergency fix was deployed on June 1, 2026. Taylor Hornby, with the assistance of AI tools, wrote a complete exploit program and generated an unlimited, undetectable amount of counterfeit ZEC in a local test environment. Currently, Shielded Labs is collaborating with other Zcash developers to explore network upgrade proposals that would allow anyone to verify the integrity of Zcash's supply.

Odaily reports that according to OKX market data, ZEC dropped to 250 USDT and is currently trading at 263 USDT, a 24-hour decline of 54.61%.

Previously, Zcash fixed a vulnerability that could allow unlimited issuance of ZEC tokens. Due to the nature of the privacy pool, it was impossible to verify whether the vulnerability had been exploited, but it also could not be proven that the vulnerability was used to issue additional ZEC tokens.

Odaily星球日报讯 ZEC 재무 회사 Cypherpunk는 모든 소프트웨어에 취약점이 존재하며, 역사적으로 비트코인은 오류로 인해 "과잉 발행"되어 1,840억 개의 BTC가 생성된 적이 있다고 밝혔습니다. 하지만 이것이 블록체인 기술을 포기해야 한다는 의미는 아니며, 형식적 검증과 증명 가능한 정확성을 통해 보안을 강화해야 합니다.

Cypherpunk는 AI 기술이 발전함에 따라 취약점 탐지가 더 빠르고 광범위해질 것이지만, 핵심은 악의적인 행위자보다 먼저 문제를 발견할 수 있는지에 달려 있으며, Zcash는 곧 출시될 업데이트를 통해 이러한 능력을 보유하고 있음을 보여줄 것이라고 강조했습니다.
