Harmony to roll back blockchain after forged ONE exploit
The rollback will revert Harmony validators to the Aug. 11 checkpoint, discarding 109,126 regular transactions and 315 staking transactions tied to the exploit.
Harmony said it will roll back its blockchain to Aug. 11 after an exploit created forged ONE tokens, abandoning more than 109,000 transactions that were confirmed after its chosen checkpoint, according to Cointelegraph.
The network said validators will revert to blocks recorded at 11:25 p.m. UTC on Aug. 11, then resume block production from the next heights using replacement databases. It said the discarded window includes 109,126 regular transactions and 315 staking transactions.
Harmony also warned that selectively restoring transactions could be unsafe because balances, contract states, nonces, and other conditions would differ on the replacement chain. Cointelegraph notes the plan followed reports that unauthorized ONE tokens had been minted and sent to exchanges.
The outlet added that Harmony said investigators traced nearly all of the forged ONE to wallets or service boundaries and are working with exchanges, bridges, and law enforcement. Cointelegraph said the token’s market cap was about $10.8 million at last look, citing CoinGecko data, and compared the situation to a separate rollback dispute involving Ravencoin.
