Cardano chain split due to a malformed delegated transaction, Intersect confirms no user loss in capital

The Cardano blockchain split into two chains due to a malformed delegated transaction triggering a software bug.
The transaction was validated on the newer version of the node, but the older version of the software rejected it, causing the network to fork. The "toxic" transaction exploited a vulnerability in the underlying software repository to split the network into a "poisoned" chain containing the transaction and a "healthy" chain that did not, Cardano's eco-governance group Intersect said in an incident report. Co-founder Charles Hoskinson initially claimed it was a "premeditated attack", but then an X user, Homer J., publicly admitted responsibility, saying he acted negligently when trying to recreate the "bad transaction" and relied on AI-generated instructions. The user said there was no malicious intent and no financial gain was made from it. Intersect confirmed that there were no user losses in capital and most retail wallets were unaffected. ADA token prices fell by more than 6% as a result of the event.
