Cardano Chain Fork Due to Stake Pool Operator Error Does Not Result in User Fund Loss

BlockBeats News, November 22, according to Decrypt's report, the Cardano blockchain split into two chains on Friday due to a format error in a delegation transaction triggering a software bug. The transaction was validated on the new version nodes but was rejected by the old version software, causing a network fork.

The Cardano ecosystem governance organization Intersect stated in an incident report that this "toxic" transaction exploited a vulnerability in the underlying software library, splitting the network into a "poisoned" chain containing the transaction and a "healthy" chain without it. Co-founder Charles Hoskinson initially claimed this was a "premeditated attack," but later a user named Homer J. publicly admitted responsibility, stating that their actions were negligent while attempting to reproduce the "bad transaction" and relying on AI-generated instructions.

The user stated there was no malicious intent and no economic benefit gained. Intersect confirmed no loss of user funds, with most retail wallets unaffected. The ADA token price dropped over 6% due to this incident.
