What's worrying the crypto community is that the bug, which had existed in the network for 4 years, was only found recently by Shielded Labs, a nonprofit developer on the privacy token system, using Anthropic's newly released Opus 4.8 AI model. The vulnerability, which Zcash said "has been remediated," if left undetected, could have allowed an attacker to print unlimited counterfeit tokens.
The disclosure had already caused panic among the crypto community and took the Zcash token down nearly 38% in the last 24 hours. Some even said on social media that “Crypto is dead. We should have pivoted to AI.”
