Cardano Chain Split Triggered by “Malformed” Delegation Transaction

[cryptohog]

The Cardano network experienced a temporary chain split on Friday after a “malformed” ADA delegation transaction exploited an old code bug in the blockchain’s underlying software library. According to an incident report from Intersect, the malformed transaction created a disagreement between node versions, leading to a network partition. Staking pool operators were instructed to upgrade their node software to restore a unified chain. While the issue was resolved, some users reported orphaned transactions and concerns over potential ADA double-spends.

At least the issue was caught before it escalated further.
