There's a distinction to be made between p2p as a network topology and p2p as a redistribution of power and agency. It's true that relays are an unsatisfying fallback to deal with the networks we have, but they still allow for meaningful p2p in sociopolitical terms. Relays that support the spirit of p2p need to be federated, stateless, and end-to-end encrypted.

you dont need relays if you use dat.

blind relays are optional and literally only relevant for specific really difficult carrier grade network conditions where direct connections might not always work.

...but even then, relay is really dynamic and any dat peer is automatically and dynamically participating im the process ..p2p, not federated

Are you saying that, aside from carrier grade NATs, dat otherwise achieves 100% direct connections?

i mean - network situations can be complicated and problematic but i would say pretty much yes in the sense of in prwctice it almost always works - 100% is too strongly framed, but it is really reliable, feel free to try.

if you dont want to use the stack and try programmatically, try keet messenger or holesail.io app to experience the reliability
