Harmony Plans Rollback Wiping 109,000 Transactions After ONE Exploit

Harmony plans to roll back its blockchain to Aug. 11, discarding more than 109,000 transactions after an exploit created forged ONE tokens.

Harmony plans chain rollback as forged ONE spreads across network

Harmony has proposed rolling back its blockchain to two Aug. 11 checkpoints, a recovery plan that would discard more than 109,000 regular transactions as the network removes ONE created through a forged mint. According to Harmony’s latest incident update on…

Harmony Sets Blockchain Rewind After Trillion-ONE Mint Attack

Harmony has shifted from evaluating several recovery options to implementing a specific blockchain rollback after an attacker exploited the network to forge trillions of ONE tokens. The recovery plan will remove the fraudulent state but also eliminate legitimate activity recorded after the selected checkpoints, making the intervention one of the most disruptive responses available to an operating blockchain. In an Aug. 17 incident update, Harmon…

Harmony Sets Rollback Plan After Forged ONE Mint

Harmony has moved from considering a rollback to publishing the exact checkpoints it plans to use after an attacker forged trillions of ONE tokens. The recovery decision will discard legitimate post-checkpoint activity as well as the malicious state, making it one of the most disruptive options available to a live blockchain. In an August 17 incident update, Harmony said validators will use replacement databases at shard 0 block 92,730,034 and s…

Harmony Plans Pre-Attack Rollback After 3 Trillion ONE Token Exploit

Harmony is weighing a pre-attack rollback after an exploiter reportedly forged 3 trillion ONE tokens, a move that would reverse chain history to a point before the incident and reset the network's token supply. The proposal marks one of the most consequential decisions the protocol has faced since...

Harmony to Roll Back Chain After 3T ONE Tokens Forged

Why Is Harmony Rolling Back Its Blockchain? Harmony plans to roll back its blockchain to a point before last week’s exploit after determining that attackers forged more than 3 trillion ONE tokens through a vulnerability that allowed previously valid transactions to be reused. The Layer 1 blockchain said validators will roll back Shard 0 and Shard 1, the two chains that make up its sharded network, to immediately before the confirmed unauthorized…
