Cardano Glitch Slows Blocks; ADA Dives to $0.30 Support
On November 21, 2025, a Cardano glitch slowed mainnet block production for about an hour, underscoring network stability concerns ahead of the December 8 Midnight sidechain launch. IntersectMBO, the primary maintainer, reported on X that a cryptographic library bug discovered in the Preview environment triggered hash size inconsistencies and a peer-selection error. Operators running Cardano Node versions 10.3.1 and above were urged to upgrade to 10.5.2 immediately to restore normal block processing. Nodes still on version 10.1.4 experienced partial halts, but updated nodes continued transaction processing via a “ghost chain.” Daedalus wallet users remained unaffected. Rapid interventions by IntersectMBO, the Cardano Foundation and IOG aimed to resolve the fork and reinforce network resilience.
The glitch sent the ADA price tumbling over 13% in 24 hours, dipping under $0.40 to test a critical $0.30 support level. Technical indicators now show an oversold RSI and bearish MACD crossover, with key resistance near $0.44. Traders are monitoring ADA price action closely for algorithmic triggers that could drive further downside.
Bearish
The Cardano glitch and resultant block slowdown have directly undermined network confidence, triggering a swift 13% ADA price drop and pushing it to critical support near $0.30. Short-term technicals remain bearish—with an oversold RSI and MACD crossover—suggesting further downside risk if support fails. While rapid node upgrades and a planned sidechain launch could bolster long-term resilience, traders are likely to stay cautious. Algorithmic sell triggers around key levels may amplify volatility, making the immediate outlook negative for ADA.
