- A crafted delegation transaction exploited a long‑standing deserialization bug, causing newer nodes to accept it while older nodes rejected it and producing two concurrent ledgers.
- Engineers issued hotfixes and a node upgrade to version 10.5.3, and resynchronization toward a single chain is progressing.
- Intersect reported that no user funds were lost and that most retail wallets were unaffected.
- An X user calling himself “Homer J” publicly claimed responsibility, describing the act as a negligent experiment without financial motive.
- Charles Hoskinson alleged the incident was a premeditated attack by a disgruntled stake pool operator, and ADA fell more than 6% following the disruption.
