How does the Query Language work on Polygon ID?

Created by Sanket Saagar Karan, Modified on Wed, 18 Jan 2023 at 08:50 PM by Parvez Shaikh

The Query Language on Polygon ID allows verifiers to design queries based on 5 operators (equals, less-than, greater-than, in, not-in) that are related to specific claims held by users. The verifier presents the query to the user via a QR code, and the user responds with proof. The verifier can then easily check if the query is satisfied based on the proof provided by the user, without accessing any personal data.
