Maybe SocialX. It will be a social media network for pictures, videos, live streams and messaging. Zk-snarks will be used to enable private communication. There will be likes and superlikes on SocialX and content that gets superliked will be rewarded with SocX tokens (SocX tokens will be easily exchangeable on exchanges for e.g. eth, btc...). More superlikes any content gets, more SocX tokens as a reward. And those reward tokens do not come from people that superliked content, but from SocialX platform (like on Steem platform). Every user will get limited number of completely free superlikes for a time period (probably daily). Think of it as a crypto-instagram of some sort.

Also, from whitepaper: "token increases in value proportionally to the number of active users on the platform, mainly due to our integrated stacking mechanism."

Tech part of SocialX team already has experience in making a social media project.
Recently SocialX partnered with ZenCash. Specific information will be released at a later stage.

Alpha is scheduled to be released on October 30th
...so that people can see their work and decide for themselves if they like the project and if they want to take part in an ICO that will take place after the alpha is published. Superlikes will not be enabled in alpha. ICO will be probably in November - date is TBA.

Alpha will be released for the members of their slack channel so if someone wants to try it out, this is a link to their slack:

They are available every day on slack to answer any questions.

Whitepaper has a lot of content, and will have even more in next version that will be announced before ICO. For those interested, whitepaper is here:
