TOR/I2P/Proof-Of-Bandwidth
Similar to the super-node/full-node project, distributing daemons which provide a decentralized anonymous network resources (computing power + bandwidth).
Difficulties would mainly revolve around how to reward proof-of-bandwidth. I believe that there was an official TOR whitepaper on a backing cryptocurrency, so the company/team behind TOR are probably interested in this.
Perhaps you'd have to worry about your volunteers/workers getting in trouble for running a TOR/I2P/Other node (not unheard of that someone will get in trouble for doing so), so perhaps a minimum age would be required for the project..
Can you think of a similar decentralized network that could benefit from a project like this?
Like/Retweet to draw attention to this idea:
