There are different ways to ‘prove’ the person in front of you is who they say they are. We also have ways to ‘prove’ the ‘stamp’ or ‘seal’ of an organisation was created by the organisation and not an imposter. We’ve also figured out ways to enable the person who the data is about, to have access and some control over it.
However, we don’t appear to have solved the multiple wallet challenge. I can have multiple digital wallets, so how can we be sure there is only one ‘me’ in the ecosystem? How can an organisation ‘check’ that I haven’t already been registered?
I don’t know.
I imagine there must be a role for zero knowledge proofs in this space, but I’m not sure. For this to work, there would need to be some sort of standard and a list of databases to ‘ask’. And maybe there is a place for a semi-closed eco-system to enable this to occur. But then are we not just back to a centralised system?
If anyone has ideas or articles to point me to on this, I’d be grateful if you’d share them.
