There is also Secure Scuttlebutt if you need extreme nomadicity

It is basically very similar in concept, just without the baggage of inconvenience which comes with crypto coins.

And there is also the DAT protocol, which again is assimilable to IPFS just without the coins, but it seems it really never took off, https://dat-ecosystem.org/

I guess coins scams is really what only can sustain these projects then :/
