CommPRO Editorial StaffBlockchain-based rewards and marketing company Refereum recently announced its partnership with gaming juggernaut PUBG Corporation, which connects PLAYERUNKNOWN'S BATTLEGROUNDS users to blockchain technology through the most creative and massive blockchain use case in gaming yet.In a first for both the blockchain and gaming industries, PUBG players can earn on-chain crypto rewards (Refereum's utility token, $RFR) for completing in-game feats — for instance, winning a match. This new rewards program involving in-game objectives is an innovative new addition to Refereum's already established work in rewarding gamers for livestreaming their gameplay, watching other players' streams, and promoting games' social media content."Gamers do so much free marketing for games through streaming services and social media, but they're rarely compensated sufficiently for it," says Refereum CEO Dylan Jones. "This is the problem Refereum aims to fix — and now, with this revolutionary new way of rewarding gamers for their in-game engagement with PUBG, we not only reward them for playing a game that they love, but for their dedication in becoming better players, too."Refereum's inaugural PUBG campaign lasts until August 20, and is the latest in a string of successful marketing and rewards campaigns that has also propelled mainstream blockchain adoption amongst the audiences of games such as State of Decay 2, Fortnite, Apex Legends, and the Battlefield series.
