This kind of idea has been floating around for a while but it takes a really smart person a decent amount of time to get a proof of concept off the ground that will excite other people and create momentum.
Your idea is a little nieve and could be accomplished in much more efficient ways using things like hashes and checksums. A new p2p protocol would need to be developed for the use case of real time messaging and historical message histories.
There are already some concept peer to peer messaging apps that use wireless to create mesh networks for the scenario of total internet or power collapse.

All creatures, including humans, possess instinctual knowledge. This is stuff we are born with. For instance: fear of snakes, or estinating how much protein is in our food by taste. Some of our instinctual knowledge is about mate selection since procreation is a very important goal for a species. We use our nose to detect if others are a good immune system match, and we use our eyes to see if they are sick or unhealthy and also assess their ability to nurture children. That last part is where the boobs come in. They make breast milk and so they are a feature that gives pleasure to see. There is no choice about it. We like what we like because of our genetic programming.
I've been using duck duck for the last 2 years and it's fine if you don't need localized results. If I'm searching for x thing in y area then I go back to Google for that.

The whole system is broken. Putting a financial incentive in front of the review process is not going to fix that.
