Hoskinson involves FBI after developer’s ‘careless’ experiment splits Cardano blockchain

Cardano experienced its first major chain split in eight years on November 21 after a deliberately crafted transaction exploited a three-year-old bug in node software, fragmenting the blockchain into two competing chains. The anomaly, which mirrored a testnet issue, caused major exchanges like Coinbase to pause ADA operations for up to 14 hours while the network stabilized. The developer, "Homer J," publicly confessed, calling it a "careless" testing accident where they relied on AI instructions without proper testing. However, Cardano founder Charles Hoskinson labeled the action a "premeditated attack" and confirmed the FBI was involved. This escalation led to one IOG employee, a Plutus developer, resigning due to concerns about legal repercussions for future development mistakes. The network eventually converged through natural consensus after emergency patches were deployed.
