But how do you know if it’s the person who bought the service or not? Email login?

I think that what remains is to show that you can do blind Schnorr + FROST naively without modifying the blind schnorr signing algorithm and the FROST signing algorithm. There’s also work on making ZKPs so you can prove things about the tx without revealing the whole tx (e.g. you could put a spending limit). Right privacy good but it also makes it had to be a backup for someone unless they can identify themselves as the true owner of the coins. Maybe there’s something there though where the blind signer would only sign if you prove the utxo it’s spending (without revealing which one) is older than X months to enforce a sort of scriptless degrading recovery mechanism. What would be cool would be to make the blind signer programmable so we don’t have to think too much about how to build the product — even better make it a reasoning AI prompt that you set up yourself to vet anyone who claims to be the rightful owner of your coins in the future. i.e. upload yourself to the cloud so you can grief your progeny as they try to claim their inheritance.

I think the cryptography for that is partly sorted out but we don’t have concrete designs on a blind signing service tbh. Do you have any thoughts about what you’d like to see?

Awesome! Yep locked in for September shipping.
