my guess:
pow for discovery and wot for spam filtering
Discussion
Yeah, but I think it's easier to leverage sats as a proxy for pow
yeah, that's good but it also requires wot (since zaps are unverifiable) so pure pow is better for discovery (if you want to find people outside your wot)
unless you meant pay for pow, that's awesome and I fully support it
I just mean that relays could charge sats for traffic. I don't know enough if that's already built in or not.
