The Cardano blockchain experienced a temporary network split after a rare software bug triggered by a staking pool operator caused disagreement among nodes about chain validity. While the issue has been resolved through rapid node upgrades, it escalated when Cardano founder Charles Hoskinson revealed that the FBI had been notified. A delegation transaction submitted with AI-generated code inadvertently triggered this unforeseen disruption. This unexpected event led to two separate chains for a short period before consensus was restored. Although the incident impacted the market briefly, no major panic sell-off occurred as investor confidence remained high. The situation has raised questions about the long-term security and resilience of blockchain networks, prompting calls for deeper scrutiny of automated code tools and robust legal frameworks for cybercrime.
