Nostr PoW is cool. I often ponder use cases and gamification. 
Discussion
i just see a half baked antispam measure.
I believe that becomes relevant when nostr gains more traction. I’m trying to imagine how it can be gamified. nostr:npub1sdxqk57gkvlq44g0c3fyuy0s2p4vvnld90nk98nf2ykf6td8gd5shm9mw4 was doing a thread with ever increasing PoW requirements just for fun.
fun is the main word in this. i'm not a dedicated expert on the subject of PoW but it's one of the things about Bitcoin that gives it that zero to one element.
i've personally worked on a proof hash function that leverages long division units in 64 bit CPUs and i know of Chia and Spacemesh (and old eth) also adding large data storage limiters to the schemes but unless the supply of miner hardware is scarce, hard to manufacture, has a lot of competion for this use case (long division vs cpu/gpus is this), and the most important thing, not possible to suddenly unleash a large amount of hash power on the network without a long lead time scaling up then they are all doomed to failure.
so this thing is an idle amusement based on what i know PoW and its market mechanics.
if it is worth something, and someone can enter this with a large amount of resources and take control of the leaderboard it will be.
Not for spam, for discovery:

it's indirectly paying for advertising.
Yes, an honest signal of value
but one that doesn't scale or disfavour spammers.
y not lightning payments for proof of spend?
It scales fine. It's how Bitcoin prevents ddos from fake blocks
It does disfavor spammers, important messages are worth putting pow into, spam isn't
payments are not verifiable because sender and receiver could be colluding to fake volume
Burning bitcoin is verifiable but does not scale
i think the problem is that if it's cheaper to produce the PoW at scale, it will be taken over by spammers, is all. used to promote influencoors, for example.
we already have a big enough problem that by default instead of 'newest' all nostr apps are ranking prominence by engagement, which is a self-fulfilling prophecy, and boring af, when these people who have risen to the top know the many simple ways to keep people engaged, and mostly that's by acting like twats.
burning is fiat mind. bitcoin is too scarce to use this mechanic anyway.
really, i think that if all messages cost a sat or two at least to store for x period of time that would be a boon for relay operators and there could be rankings for higher spend posts, and relays competing to be the most connected to the most spendy users and their userbase.
ok, you don't get it but I still like you
this was the most recent effort to use the hashkash style proof of work in a messaging protocol.
it entirely depended on the PoW to not enable spam.
look at the date on it. hasn't been updated since 2016.
at least do the basic research before you waste your time on something that is a well trodden path.
I already told you my interest isn't in spam prevention it's in discovery
But you are too self-absorbed to listen
No worries
yes, "Discovery" as in advertising. why do you insist on using a euphemism for promoting the visibility of posts by spending a resource?
It's a different thing. In advertising you pay the person that owns valuable content to put ypur message next to the valuable content to leach some attention for your message
In honest signaling (what deer do when they grow antlers) you provide a verifiable proof of wasted resources in order to demonstrate the value of something (in the case, of nostr, the value of a message). No one is paid, attention is not acquired by affinity but by the costly signal itself.
Different concepts require different words so that we can talk about each individually. Or are you to self absorved to even understand that?
discovery means digging through random stuff.
it would be enabled simply by having a view on clients that collects a comprehensive list of accounts and then requests them randomly without regard for time or sequence, lets you discover something in the rabble.
it's not discovery when someone is paying a resource to be visible. that is advertising and your whole idea is disingenuous and dishonest makes me suspicious of you.
lmao, I don't think that's what discovery means
imagine thinking that finding burried treassure is the same as just finding dirt.
pow is the metal you detect with your metal detector. usually trash, but sometimes treassure. otherwise you'd just be looking through dirt forever.
smh
What am I seeing here?
Some clients do Proof of Work. Will find leading zeros for you eventually id in nostr.
That doesn't help me. Is this a nostr node?
It’s specific client I use in desktop
https://github.com/mikedilger/gossip
If a nostr client implements PoW, it will hash the event (which is how the event ID is created) until there are sufficient leading zeros.
