REDACT Turns Web Sessions Into Zero-Knowledge Credentials

zktls.tech Observed source
Editorial interest 82/100 Selection signal · not a rating of the site

REDACT presents a zkTLS protocol for proving a single fact from an authenticated HTTPS session without disclosing the underlying page, account, or value.

Landing page captured for the 2026-09-08 issue.

Field notes

The homepage lays out a four-stage flow: notarize a TLS session, commit the full response, select one field, and prove a predicate over it. Its examples use follower counts, Stripe revenue, Uber ratings, and Coinbase verification status, while the disclosure panel lists session cookies, authentication headers, the exact field value, and the remaining response body as client-only or committed. The page identifies Groth16 on BN254 as its proof system and labels the project a v0.2 testnet.
