Has anyone experimented with barter nfts? I borrow a cup of sugar from neighbor and issue him a “cup of sugar nft” … solves dual coincidence of needs problems without a fungible currency. Crypto-hardened IOUs.

i dont think you need blockchain for this though; just digital signatures e.g. my neighbors signs "IOU 1 cup of sugar" and sends it just to me; i can then just show the signed message to anyone in case of some dispute, which (besides verifying the sig) is resolved offline anyway

if you're using a social enforcement layer you totally can, because you don't have to worry about double spend e.g. if i have an IOU i want to give you, i just sign "i transfer IOU w hash 0xABCD to " if i try to send same IOU multiple times it's easy to prove & kick me out

i still think it's a good idea btw; passing around digital signatures is basically how BTC lightning works you'd want integration w crypto wallets for key management & automated workflows for sign, send, verify sigchain, etc no blockchain still good bc no fees & works offline
