"It works on Emercoin" means that Polybius founders want to use Emercoin NVS (blockchain name-value storage) as the decentralized database for storing their public keys, transactions etc.

They could decide to use a centralized database (like MySQL) and say that "it works on MySQL so Oracle is our partner".

As for Emercoin founder Oleg Khovayko, it is suspicious that Polybius use the same Khovayko's photo that is pulished on Emercoin website.
