Ravencoin

Harmony’s ONE token fell about 26% in Asian morning trading after an apparent exploit created roughly 4 billion new tokens. The team said it is working with exchanges to freeze funds while preparing a software patch and considering rollback options.

Ravencoin is facing a serious network dispute after invalid blocks entered the chain through a critical software flaw. Major mining pools are rebuilding the chain from before the first flawed block, raising the risk that recent payments, deposits and withdrawals could be reversed.
