we are planning to have different "tiers" of badges in https://badges.page depending on NIP-13 PoW difficulty, adding PoW is a nice way to add "rarity" to badges imo.
I get the PoW angle.
Rarity will also come from trusted issuers, with verifiable supply.
So #[5] could issue based on verified card ownership.
#[6] could issue based on verified Sats-Man high scores.
We need a way to surface non-computational PoW scarcity.
