Question 1

What is Harmony's rollback plan?

Accepted Answer

Harmony intends to rewind shard 0 to block 92,730,034 and shard 1 to block 94,978,278, both at 2026-08-11 23:25:37 UTC, using replacement databases, with a new client (v2026.1.2) that rejects the exploit's block hashes. All blocks after those checkpoints, including legitimate user transactions, would be discarded.

Question 2

How did the attacker mint the ONE tokens?

Accepted Answer

According to Harmony's August 13 update, a flaw in cross-shard receipt verification let valid receipts be reused, crediting a shard without a matching debit and inflating native ONE inside empty, zero-gas blocks, with a second pre-staking quorum bug possibly involved.

Question 3

How much did ONE fall after the mint?

Accepted Answer

Reports put the drop at about 37% to 40%, with the token trading near $0.0008 and its market capitalization falling to roughly $11.5 million, according to Cryptopolitan.
