Basically, Revain is an Ethereum based token that interfaces with the Revain online business review platform. It utilizes the Ethereum blockchain to permanently record reviews approved by both the system and the business owner. As far as i know, there are two Revain tokens: R and RVN. While R is bought and sold in the crypto markets, RVN token remains solely on the Revain system. Revain is hosted online. Users register an account and then have the ability to interact with the system, which as of this writing is limited to reading and writing reviews of ICOs and existing coins
The main thing i like about it provides a decentralized environment where reviews cannot be changed by businesses except via dispute process settled by human mediators. the sophisticated AI software combats submission of falsified, duplicate or otherwise fake reviews, providing review browsers with a more accurate rating of a business which is awesome.
Revain token is already listed on many big exchanges but i am waiting for it to be listed on the world's biggest exchange i.e Binance.
