A deep dive into self-sovereign identity, W3C Verifiable Credentials, and how we built PolyID from scratch.
Self-sovereign identity (SSI) puts users back in control of their own credentials. Instead of a central authority holding your data, you hold verifiable credentials in a digital wallet on your phone.
Credo-TS (formerly Aries Framework JavaScript) gives us a battle-tested toolkit for DIDComm messaging, credential issuance, and proof exchange — all from a React Native app.
PolyID pairs a React Native front end with a Credo-TS agent running on-device. Credentials never touch our servers — they live encrypted in the wallet.
The whole point of SSI is that the user, not the platform, owns the data.
In the next post we'll walk through issuing your first credential end to end.
