a vault! with one of those big doors i get excited when thinking about Bitcoin cash as in paper money that is like bitcoin. I personally don't like intermediating every purchase by looking at a phone, especially in foreign countries where I'm struggling with SPanish or something. it just needs a private bank to issue it, whose reserves are auditable on the mempool.space. and each printed note would be a claim on the private bank's bitcoin. Over time someone might lose their satoshi notes, so the reserve would slowly grow larger than the supply of actual notes. https://image.nostr.build/e204d17399885e733d38dd0bfc9c8a151c8d04c192ec8210cb22c8e944490615.jpg
And bank locked boxes. Someplace to save your valuables. I think some also offer multisig services for companies and trusts, so that there's always an impartial person approving transactions. And notary services.
yes, as a renter in an old place that's already been water damaged once, I need this.
We already have paper wallets, actually. That used to be really popular.
And you can print Lightning eCash on paper.
ok, i will look into eCash. i think what i'm looking for is just dollar bills/local currency for now. but fast forward 10 years, and it will be interesting to see how it's done because I really don't want to carry around a phone in the future.
Yeh ... physical bitcoin cash notes would be handy
yeah, how would they look... would they have some little RFID circuits printed under the surface to match it with database at the bank that issued them. authenticity could be verified with a phone NFC(API to regulated portal that checks serial number against banks issued paper and BTC holdings) . ownership is just whose hand is holding it.
I wonder if it's possible to cryptographically give a serial number to one piece of paper that couldn't be counterfeited
