According to a <a href=\"https:\/\/x.com\/harmonyprotocol\/status\/2089280253701324989\" target=\"_blank\" rel=\"noopener noreferrer\">technical update released by the team<\/a>, Harmony will roll back Shard 0 to block height 92,730,034 and Shard 1 to block height 94,978,278, effectively reverting the state of the blockchain to 23:25:37 UTC on Aug. 11, before the initial breach.<\/p>\n<p>The incident began on Aug. 12 when an attacker exploited vulnerabilities in cross-shard receipt validation and quorum verification code to forge tokens. While early estimates identified<a href=\"https:\/\/x.com\/harmonyprotocol\/status\/2087428910829261013\" target=\"_blank\" rel=\"noopener noreferrer\"> an initial illicit minting of 4 billion ONE tokens<\/a>, subsequent on-chain analysis revealed that a single wallet attempted 534 fraudulent transfers of 5 billion ONE each within a 106-second window. A total of 477 of those transactions succeeded, resulting in the unauthorized creation and transfer of 2.385 trillion ONE tokens.<\/p>\n<p>The massive, unexpected surge in token supply triggered an immediate crash in the price of ONE, which dropped by more than 30% as billions of forged tokens were quickly routed to cryptocurrency exchanges.<\/p>\n<p>Harmony developers deployed an emergency patch, Mainnet v2026.1.1, to prevent further unauthorized token creation, suspended <a href=\"https:\/\/www.bitcoin.com\/sv\/get-started\/blockchain-tech\/infrastructure\/what-is-cross-chain-interoperability\/?_gl=1*2ch164*_gcl_au*MTU5NTg4OTAzNC4xNzgxNTQzNzg1*_ga*MTU3OTQwMTMwLjE3NzM3NjQ2MDc.*_ga_ERLPF60ZDD*czE3ODY5OTQ0NjEkbzYzMiRnMSR0MTc4Njk5NDYwMiRqNTEkbDAkaDA.\" target=\"_blank\" rel=\"noopener noreferrer\">cross-chain bridge<\/a> services, and requested that cryptocurrency exchanges freeze wallet addresses linked to the exploit.<\/p>\n<p>In Monday\u2019s announcement, the project team stated it had evaluated alternative remedies\u2014including targeted token burns, blacklisting specific address clusters, selective transaction replaying, and token migration\u2014before concluding that a fixed-window rollback was the only solution that would not risk damaging unrelated funds or causing permanent chain state inconsistencies.<\/p>\n<p>The team confirmed that over 99.9% of the forged token flows have been traced with the assistance of an independent security firm, and that law enforcement, bridge providers, and partner exchanges are coordinating on <a href=\"https:\/\/news.bitcoin.com\/onchain-researchers-discover-63m-in-ethereum-from-harmony-bridge-attack-moved-hackers-attempt-to-launder-funds-on-major-exchanges\/\">the recovery effort<\/a>.<\/p>\n<p>Under the rollback plan, network validators will adopt replacement databases starting at the target checkpoint blocks and begin regenerating new blocks from that point forward. Harmony, <a href=\"https:\/\/news.bitcoin.com\/harmonys-100m-hack-was-due-to-a-compromised-multi-sig-scheme-says-analyst\/\">which was also hacked in 2022<\/a>, noted that 141,628 consecutive blocks on Shard 0 generated between the rollback point and the network pause, containing 109,126 regular user transactions and 315 staking transactions, will be permanently discarded.<\/p>\n<\/p><\/div>\n<p><a href=\"https:\/\/news.bitcoin.com\/blockchain\/harmony-protocol-to-roll-back-network-after-massive-exploit\/\">Source link <\/a><br \/>\n<br \/><\/p>\n","protected":false},"excerpt":{"rendered":"<p>(Originally posted on : Bitcoin News ) Key Takeaways Harmony Protocol suffers exploit resulting in 2.385 trillion unauthorized ONE tokens minted on Aug. 12.
