Cardano details a mainnet chain partition, rapid node upgrades, and Charles Hoskinson’s unity call as the network regains stability.
Cardano released new details after a malformed transaction caused a temporary chain partition on the network. The ecosystem pushed swift upgrades to restore consensus, while Charles Hoskinson urged the community to stay unified during the incident.
Chain Partition Triggered by Malformed Transaction
Cardano developers confirmed that today’s disruption came from a malformed transaction that exposed a bug in a core software library. The fault caused the network to split into competing chains, slowing block production and creating visible delays across services.
At the same time, Stake Pool Operators (SPOs) reported divergence in block histories, prompting immediate coordination among engineering teams and ecosystem contributors. The split increased the urgency for a synchronized fix as nodes running older versions struggled to converge.
Intersect, the Cardano member-based organization, said upgrades to node versions 10.5.2 and 10.5.3 began restoring full network alignment. They emphasized that the healthy chain is already becoming dominant as operators adopt the updated software.
Coordinated Response Pushes Network Toward Full Recovery
According to Intersect, ecosystem teams mobilized quickly once the partition appeared. Engineers, SPOs, exchanges, and infrastructure providers coordinated in real time to stabilize the chain and ensure the patched clients were deployed across major operators.
A dedicated working group is now reconciling ledger discrepancies and validating block histories as part of the stabilization effort. Their goal is to confirm full convergence across all nodes before issuing a detailed after-action review.
