"NFTs on nostr"
There was a thread about NFT on nostr the other day which got much hate and yeah, I think it was a meme token for the lulz that didn't solve any problem but I think the topic is worth exploring on nostr.
My hypothesis is that ERC20 and later standards were "successful" because they standardized certification in an ecosystem that already had cryptographic identities and tools to securely store keys.
Most applications of ERC20 would have been better without a blockchain and almost all tokens gained little from being all mashed together on the same blockchain.
On nostr, many are allergic to tokenomics and all that shitcoin BS but ... we have "badges". Not all love them and we certainly don't give them much weight yet but it is already a kind of certificate with an issuer and a recipient, leveraging identities on nostr. There is no badge I know of that would raise eye-brows but in their essence, badges are as of now non-transferable NFTs. An artist could issue them and sell attribution with the promise of only selling 20 attributions. Violating this limit would be possible and nostr would not always allow to proof which ones are the first 20 but you could proof that the issuer over-issued given the signed events.
And we could make these badges transferable in a way that would be good enough for many token applications where the issuer would act as a central authority. nostr:npub1jg552aulj07skd6e7y2hu0vl5g8nl5jvfw8jhn6jpjk0vjd0waksvl6n8n just now gave away some hardware-wallet-tokens that are worth one of their devices in their store but as nostr-badge-like events it could work, too. Their store could allow the owner to buy a badge for another nostrich with it. Boom. Transferable.
