[Cardano Experiences Chain Split Due to Malformed Transaction, Intersect Confirms No User Funds Lost] The Cardano blockchain encountered a software vulnerability triggered by a malformed delegation transaction, resulting in a split into a 'poisoned' chain containing the transaction and a 'healthy' chain without it. The new version of the node accepted the transaction, while the older version of the software rejected it, causing the network to fork. Cardano's ecosystem governance organization, Intersect, confirmed that no user funds were lost, and most retail wallets were unaffected. Co-founder Charles Hoskinson initially referred to the incident as a 'premeditated attack,' but X user Homer J. admitted the issue was caused by negligent operation, with no malicious intent or financial gain involved. The price of the ADA token dropped by over 6% due to the incident.
