zkTLS: Blockchain APIs for Any Data
Zero-Knowledge Transport Layer Security (zkTLS) could be a fatal blow to closed networks controlled by corporate giants. Emerging platforms now have the ability to compete with behemoths like Facebook and Amazon by leveraging zkTLS.
zkTLS allows users to permissionlessly migrate any of their identity data from across the internet, giving new networks a powerful way to leverage existing ecosystems. It enables users to freely switch between platforms without starting from scratch. Most importantly, it achieves this without compromising data privacy or security.
We are seeing crypto applications creatively utilize zkTLS.
zkPass allows users to verify their traditional credit scores on-chain. OpacityNetwork enables Uber drivers to port their ratings to teleportxyz. It also allows drivers and restaurants to migrate their reviews from DoorDash to NoshDelivery.
Here’s how zkTLS works:
Transport Layer Security (TLS) secures over 95% of internet connections. It represents the “s” in “https” found in most URLs. TLS connections ensure:
-
Interactions between servers (e.g., your bank) and clients (e.g., your phone) are trustworthy.
-
Data is confidential.
-
Data integrity is strong.
zkTLS introduces a third-party verifier that validates the security of communication between client and server—without compromising security. There are two primary approaches to implementing this verification:
Proxy-based: A proxy server acts as an intermediary, monitoring encrypted traffic and partially decrypting it to verify the client's credentials.
Multiparty Computation (MPC)-based: The client and verifier interact with the server such that the verifier can prove the authenticity of messages, while the server remains unaware of the verifier’s presence.
To preserve privacy, the client uses zero-knowledge proofs to demonstrate specific facts about data without revealing the actual information.
For example, a proof can show that their bank balance exceeded $1,000 on a given date—without disclosing the exact amount. Alternatively, I can prove my wallet belongs to a verified Indian citizen without revealing other details such as my name or date of birth.
These proofs can be recorded on a blockchain, where they become permanent and accessible for validation by other applications.
Data control empowers internet giants, enabling them to build networks based on personalized experiences that lock users in. zkTLS breaks down the walls that trap billions today, creating a more open and decentralized future.
