I am under the impression that crypto took the spotlight to almost anything P2P related in the past decade. Besides crypto, is there new being done with?
Radicle is pretty interesting: <a href="https://radicle.xyz/" rel="nofollow">https://radicle.xyz/</a><p>It's a P2P source forge similar to GitHub or Gitlab.
P2P broadcast is interesting. Send your video to two users, then they send it to two more. Makes things affordable.<p>P2P VPN I also like. Users connect directly instead of routing all traffic through relay.
