OpenPassport is developing tools allowing users to generate proofs of humanity, nationality and age using their government-issued passport. We want to make it easy to extract the signed data from passport chips and verify it. It unlocks uses cases in proof of unique identity, sybil resistance and selective disclosure of private data.

Our main work right now is the OpenPassport app and circuits that currently supports the most common signature algorithm used by country authorities.

There is no additional trust assumption other than the issuing country. All proofs are generated on the user's device and the personal data stays there.

Our work is fully open source here. We believe in using and aggregating already existing attestations to let users build strong and reliable digital identities while only disclosing the information their want public.

We are actively looking for contributors to collect samples of passport data and help implementing verification circuits of lesser-used passport signing algorithms using available primitives (rsa/ecdsa/sha). Money will go towards hiring developers to contribute.
