PoW for antispam is gonna be useless if that PoW has an ASIC for it.

i've studied the subject extensively and the only time i saw an example of PoW that was remotely viable it was bound to creating commitments for spends of coins for a duration of time (it was an eth fork) and the number of solutions allowed per account per minimum amount was pretty small. making other accounts of course you could 'stake' on more but yeah, point being that it depended on real economic limitations, so to speak.

as i see it, nostr's going to have a spam problem without the notion of a pay-per-byte model for posting, in the long run. we just haven't seen enough adoption to lead to that.

which is also why the "adoption at any cost" types should be eyed with suspicion since we aren't ready. but hey, it's the endless war between marketing and dev right?
