Show HN: The Bitcoin Note – Secure, Self-Custodial Bitcoin Wallets in Cash Form

What does the transaction look like on the chain?

I feel ridiculous in taking this seriously, but it’s got me curious.

One thing that people seem to be missing: you could take the note, pay for something, then that person pays for something else and so on down the line until a person cuts the note to put it in their wallet for online use. That seems to sufficiently anonymize the transactions again, but maybe I’m wrong.

I do like the graphic design though.

Depending on where in the lifecycle the note is, it's either a 2-of-2 multisig transaction or 1-of-2 multisig transaction, using only the user key in the latter case.
