Cardano Recovers From Chain Partition Crisis

Cardano Network Restores After Malformed Transaction Causes Chain Split

• A malformed transaction exploited a deserialization bug, causing a temporary chain split on the Cardano mainnet.
• The issue was resolved by engineers through hotfixes and node upgrades, ensuring no user funds were compromised.
• The incident was triggered by a crafted delegation transaction exploiting a cryptographic library bug from 2022.
• Operators upgraded nodes to version 10.5.3 to merge the network back into a single chain.
• The wallet responsible for the transaction has been identified, with possible ties to a former Incentivized Testnet participant.
• The FBI is investigating the event as a potential cyberattack.

The Cardano blockchain quickly recovered from a chain partition caused by a malformed transaction, with engineers implementing fixes and no user funds affected. The FBI is investigating due to potential malicious intent.
