Zcash (ZEC) fell by about 30% after Shielded Labs said it had uncovered a major bug in the network that had gone unnoticed for four years. The disclosure triggered a sharp move lower in the privacy-focused cryptocurrency.
According to the report, the bug had remained undetected for an extended period before being identified by developers at Shielded Labs. The exact technical impact of the flaw was not detailed in the source material, but the revelation was enough to unsettle traders.
The decline added pressure to Zcash as market participants reacted to the news. The move comes as the project continues to draw attention for its privacy features and ongoing development activity.
Zcash has experienced volatility in the past, but the latest drop highlights how security and protocol issues can quickly affect sentiment around digital assets.
