Harmony Is Erasing 109,000 Transactions to Undo a Token Forgery

Harmony has announced it will roll back its layer-1 blockchain to a checkpoint recorded at 11:25 pm UTC on August 11, discarding more than 109,000 transactions confirmed after that point, following an exploit that allowed attackers to forge ONE tokens.

The abandoned window contains 109,126 regular transactions and 315 staking transactions. Harmony stated that selectively restoring individual transactions is not a viable option because balances, contract states, nonces and other chain conditions would be inconsistent on the replacement chain. Validators will build new blocks from the next available block heights using fresh replacement databases.
