The problem
Showing a full ID to prove age or city reveals far more than needed.
What to build
Prototype a credential flow where a person proves only a claim, such as over 18, without sharing the rest.
Success looks like
A working proof and verification demo and a threat analysis of misuse and replay.
Suggested technologies
- Verifiable credentials
- Zero-knowledge proofs
- Selective disclosure
- Wallets
- Threat modelling
