Cardano Network Disrupted by 'Poisoned' Transaction Attack

Cardano's blockchain split into two ledgers on Friday after a malformed delegation transaction triggered a software validation flaw, according to Intersect, the network's governance organization. Nodes running newer software accepted the transaction while older nodes rejected it, so operators built blocks on different branches until patched software was deployed. Intersect said no user funds were lost and urged operators to upgrade. A user posting as Homer J. on X said they submitted the transaction while trying to reproduce it and apologized, while co-founder Charles Hoskinson called it a premeditated attack by a disgruntled stake pool operator. ADA's price fell more than 6% following the incident.
