You can do this using government issued certificates. In Spain you send them a CSR and then attend an appointment with a clerk who checks your passport/national ID. Afterwards they send out the certificate.
It's used for online authentication and signing scanned documents. Overall a good system.
You don't have the ability to trade them like NFTs, but that makes no sense for identities.
- tsujp 5y agoThat does sound like a good system indeed. By extension imagine if you could login to anything using that certificate if it was digital. The problem with digital data is that it can be copied arbitrarily. NFTs prove authenticity of some data, so now your identity can be provably yours, only a single one can exist, and you can use it to login to things, sign a message that is provably from you etc. Yes NFTs are tradable because they are tokens but you don't have to, and I'd argue an extension to ERC721 which limits NFTs to only a single issuance with a single token would make such a system reasonbly whole.
- boxed 5y agoWe have a system called BankID in Sweden where you can do exactly that. And sign stuff and it has the same legal status as a signature on paper. > The problem with digital data is that it can be copied arbitrarily. And NFTs aren't digital data? I don't understand the distinction.
