if spammers want to PoW their spam, good for them!
because that's kind of the point:
now they needs to invest in real-world real sources to sustain their load, so they have to carefully calculate how far they're willing to go with their spam.
and relays can always set a PoW limit that is high enough.
but I don't think BitAxes will be useful here!
fun fact I learned from skot9000:
Bitcoin mining ASICs can only calculate sha256d hashes for 80 byte preimages.
maybe a skillful hacker could make something work with severe limitations on note size, but I'm actually quite curious to see a potential economy of nostr note mining around GPUs 🎮⚙️

NIP-13 (PoW notes) will eventually fade reply guys into irrelevance
eventually, Nostr Relay reputation will be based on their min PoW thresholds.
anyone who wishes to publish to a reputable Nostr Relay will need to either zap them, or submit a high PoW note
🦌
the solution is NIP-13
high reputation relays should establish a min PoW threshold to mitigate spam

🗒⛏ notemine_hw ⚡⚙️
I recently discovered the notemine crate, which is a rust-base note miner.
the project compiles to WASM and caters for a web-native experience.
so I forked it into notemine_hw with the goal to support hardware acceleration (GPU, FPGA, ASIC) for mining nostr notes.
most of the boilerplate is bootstrapped (including CLI), while the WASM stuff were removed.
next steps are integration of Metal (MacOS) and OpenCL (Linux) libraries to replace the CPU-based SHA256 hashing.
I'm quite busy doing PoW on SV2 so I'm not sure how far I will get, but if any Nostr-PoW enthusiasts want to carry on the torch, contributions are very much welcome
ok that's exactly what [NIP-13](https://github.com/nostr-protocol/nips/blob/master/13.md) does
oops sorry, correction:
higher difficulty notes are more* likely to be published
whenever there's spam, relay will raise the difficulty threshold
here's a brainfart NIP to solve this problem:
introduce PoW scores for notes as a filtering criteria on relays
a note is only published if it carries a hash above some difficulty
higher difficulty notes are less likely to be published
