tags. Let's write the final content. I'll write: Harmony released a mainnet patch on Aug. 12, version v2026.1.1, to fix two verification paths. The patch comes after reports of an unauthorized ONE mint.
The patch changes how the network verifies certain transactions. Specifically, it addresses a quorum check that affects committees formed before the staking epoch. It also changes a cross-shard receipt mechanism that could apply the same transfer more than once.
The quorum check fix
The quorum check is part of the network's consensus logic. It ensures that a committee has enough validators to approve a block. The flaw affected committees that existed before the staking epoch. Those committees might have passed a quorum check they shouldn't have. The patch corrects that verification path.
The cross-shard receipt fix
The second fix targets a cross-shard receipt mechanism. In Harmony's sharded architecture, transactions can move between shards. A receipt confirms that a transfer happened. The flaw could apply the same transfer more than once, meaning a user might receive duplicate funds. The patch changes the verification path so that each transfer is applied only once.
The unauthorized mint reports
The patch was released after reports of an unauthorized ONE mint. Those reports surfaced before the patch went live. Harmony hasn't disclosed how many tokens were minted or whether they were recovered. The company only said the patch addresses the underlying issues.
Patch now live
The patch is now live on mainnet. Node operators need to update to v2026.1.1 to get the fixes. The changes are in effect as of Aug. 12.
