Relive the tumultuous 48 hours (November 20,22, 2025) when the Cardano mainnet experienced an unprecedented chain partition. A malformed delegation transaction exploited an obscure deserialization bug in the node software, causing the blockchain to temporarily run on two parallel ledgers the "healthy" chain and the "poisoned" chain. Learn about the immediate developer response, which involved forming an emergency "war room" and rushing out hotfixes (like node version 10.5.3) for stake pool operators (SPOs) to install. While the incident was condemned as a "premeditated attack" and led to a sharp drop in ADA’s price, the network never went fully offline. Discover how the resilient protocol survived this "catastrophic event," leading to the network’s convergence back to a single, unified chain without any loss of end-user funds.
