BlockBeats News, August 17th, Harmony Protocol announced the rollback plan for the ONE token's abnormal inflation incident, planning to rollback Shard 0 to block 92,730,034 and Shard 1 to block 94,978,278, with both blocks timestamped at August 11, 2026, 23:25:37 UTC. Validators will use the replacement database for the corresponding blocks and will subsequently regenerate blocks at heights 92,730,035 and 94,978,279.

Harmony stated that the first confirmed fraudulent inflation occurred in Shard 0 at block 92,730,036, hence choosing the previous block as a safety buffer. After evaluating solutions such as targeted burns, blacklisting, selective transaction replay, token migration, and direct database rollback, the team concluded that these solutions could potentially impact unrelated funds or lead to chain state inconsistency. Therefore, the final decision was to implement a fixed rollback window. Harmony disclosed that a wallet responsible for the fraudulent inflation attempted to transfer 534 transactions of 5 billion ONE each within 106 seconds, with 477 successful transactions totaling 23.85 trillion ONE transferred. The team mentioned that fund tracking has covered over 99.9% of the fraudulent ONE path, but tracing it back to a "wallet or cluster" does not necessarily confirm individual identities or guarantee the safe destruction of related funds.

Furthermore, Harmony has completed a full archive of Shard 0 from block 92,730,035 to 92,871,662, involving a total of 141,628 consecutive blocks, 109,126 regular transactions, and 315 staking transactions. The team stated that all blocks and regular transactions after the rollback checkpoint will be discarded. Currently, they are collaborating with exchanges, cross-chain bridges, and law enforcement agencies to assess the impact and devise solutions. Harmony mentioned that an independent third-party security firm has reviewed the incident, confirming the fraudulent inflation and identifying the main fund flows. Validators are required to follow the official recovery process to execute the rollback operation.
