Verifies data from Codeforces Rating and Tag (codeforces.com).

Provider to get user's codeforces rating and tag

Primary data point: Rating.

Reclaim Protocol generates a zero-knowledge proof that a user holds an active Codeforces Rating and Tag session and exposes the following verifiable data points:

• Rating
• Tag

How it works

1. Your user starts a verification session and signs in to Codeforces Rating and Tag as they normally would.
2. Reclaim Protocol observes the encrypted Codeforces Rating and Tag session through a zero-knowledge proof system, with no credentials leaving the user's device.
3. Your application receives a cryptographic proof of the user's data — verifiable on-chain or in your own backend.
