Harmony plans chain rollback as forged ONE spreads across network

Harmony has proposed rolling back its blockchain to two Aug. 11 checkpoints, a recovery plan that would discard more than 109,000 regular transactions as the network removes ONE created through a forged mint. Summary Harmony plans to roll back its blockchain to two checkpoints from Aug. 11 following a forged ONE mint. More than 109,000 regular transactions and 315 staking transactions would be discarded under the recovery plan. One forged mint wallet moved 2.385 trillion ONE through 477 successful transfers in 106 seconds. Harmony said exchanges, bridges and law enforcement are assisting with the investigation. According to Harmony’s latest incident update on X, validators would retain shard 0 block 92,730,034 and shard 1 block 94,978,278, both recorded at 11:25:37 p.m. UTC on Aug. 11, before restarting the network from replacement databases built around those checkpoints. Under the plan, new blocks would begin at heights 92,730,035 on shard 0 and 94,978,279 on shard 1. Harmony said client version v2026.1.2 has been configured to reject the abnormal block hashes linked to the incident, preventing validators from accepting the affected chain history after the restart.
