Zero-Knowledge Transport Layer Security (ZKTLS)

Zero-knowledge Transport Layer Security (zkTLS) is a name for methods that let someone prove to a third party what a website returned over a secure connection, without handing over their password or the whole page. Transport Layer Security is the encryption behind HTTPS, and it protects data between a user and a site but gives no proof that can be shown to anyone else. zkTLS adds that proof. Approaches vary: some use multi-party computation so a verifier shares in the connection, some route traffic through a proxy that witnesses it, and some use secure hardware, often combined with zero-knowledge proofs to reveal only one fact, such as "balance above 1,000 dollars". Proposed uses include bringing web data on chain without a traditional oracle and private identity or income checks. The field is early, and each design rests on different trust assumptions.
