What happened
Harmony says an exploiter forged roughly 3 trillion ONE tokens. In response, it plans a rollback to before the attack, affecting about 109,000 transactions.
Why it matters
A rollback can reverse activity beyond the exploit itself, making it a significant network-integrity event for affected Harmony users and applications. Harmony’s stated reason is that selectively restoring transactions would be too risky.
What to watch next
The key receipt is the network’s implementation of the proposed rollback and the resulting treatment of the affected transactions. The record also notes a separate rollback dispute involving Ravencoin, but provides no further detail tying the two situations together.
Watch for confirmation that Harmony has implemented the rollback and for a clear accounting of the roughly 109,000 affected transactions.
