Cronos rolls back blockchain to recover $111 million in crypto

Cronos validators reversed nearly two hours of blockchain history in an effort to recover user assets worth about $111 million, CoinDesk reported. The rollback followed an attack that targeted the network, but it did not restore all of the affected funds. Before Cronos halted the blockchain, the attackers managed to take approximately $9.19 million. The decision to rewrite recent transaction history is controversial because blockchain networks are generally expected to preserve an immutable record of activity. The incident puts attention on Cronos and its CRO token as the network responds to the attack and assesses the outcome of the rollback. Details supplied by CoinDesk did not indicate how much of the targeted crypto was ultimately recovered or provide further information on the attackers.
