A seven-year-old blockchain is permanently abandoning its own network to seek refuge on Ethereum

Harmony is proposing to shut down the blockchain it controversially restored through a rollback less than three weeks ago.The Sept. 6 plan would end Harmony’s independent network, move ONE to Ethereum, and preserve the token through a snapshot and airdrop, reversing the project’s position from Aug. 17, when it rejected migration as too disruptive.Instead, Harmony chose to roll back the chain after an Aug. 11 exploit that allowed attackers to reuse cross-shard receipts and mint tokens without corresponding debits elsewhere.The project initially reported 4 billion ONE created in the attack. Its broader reconstruction later put unauthorized issuance at roughly 3.01 trillion ONE across six forged transactions.Harmony completed the rollback on Aug. 21, discarding more than 109,000 regular transactions and 315 staking transactions from the affected shard-0 archive, and said the network was operating normally.This represents the second major attack the blockchain network has suffered in recent years.In June 2022, Harmony’s Horizon bridge was drained of nearly $100 million in an attack the FBI later attributed to North Korea’s Lazarus Group.The exploit marked a major setback for the networ...
