Waves rolls back network after blocks minted with abnormal fees

Layer-1 blockchain Waves (WAVES) said a third party created blocks using abnormally inflated fees, causing some addresses to be credited with non-existent WAVES. The network was rolled back to block 5,481,020 at 11:55 p.m. UTC on Nov. 8 to remove those WAVES, and it is now operating on a new chain starting from block 5,481,021. All nodes must install v1.6.5, which contains the fix, and manually roll back in line with the release notes. Transactions made between 11:55 p.m. UTC on Nov. 8 and around 10:16 a.m. UTC on Nov. 9 may have been affected by the rollback. Users experiencing related transaction issues can contact the customer support team.
