What problem does Vega solve?
Vega lets users prove facts such as age, personhood, or professional status without uploading a government credential. The service sees a ZKP, not the full ID.
answer
intermediate
Why is Vega fast?
Vega splits SHA-256 hashing into repeated step circuits, folds them with NeutronNova, and proves the folded instance with Spartan. This avoids one large circuit tied to credential length.
answer

What does NovaBlindFold add?
NovaBlindFold folds a real instance with a random instance to hide the witness through a small verifier-check constraint system. Its overhead does not scale linearly with all secret data.
