What if you could opt for a custodian, and the designation can't change very often (like open enrollment)? Give a trusted friend the right to set your calorie

Give a trusted friend the right to set your calorie limit, and if it doesn't work out, try a different friend next week--but you can only change it between 10AM and 2PM on Mondays.
- willcipriano 5y agoYeah I could see maybe a credit card sort of offering with these rules. I don't think credit cards get that granular level of data however. Then I would only have to commit to only carrying around that card.
- __MatrixMan__ 5y agoYeah, let's not hand that sort of data to the credit card companies. It might be a good use case for homomorphic encryption--where the transaction processor computes a go/no-go result without knowing why (and then you scan a QR code and decrypt on your device). I was thinking of having it decoupled from payments, sort of a more customizable replacement for the ID-checks that we currently do when buying alcohol. I think you could do zero-knowledge trickery to avoid the privacy problems. But then again, an API for a third party to cut off your access to resources might be too juicy of an abuse-enabler to be worth building.
