Utopia is a platform that provides P2P ecosystem. They have chat, mail, browser and the last time I checked they were launching music streaming within thier platform. Thier ecosystem is fueled by thier native token Crypton($CRP). The token is currently traded on a few exchange and is listed on CMC. You need to download it on your desktop or mobile device to access Utopia. I have participated in its review and found it intresting. You can visit their website to know more about it. If you are interested in participating in the review campaign then you can check this thread, the campaign is being managed by joeperry.
