Building a Verifiable Internet.
Proving Data Without Revealing Secrets.
Today's internet is a collection of isolated "fortresses" - platforms that retain user data and control access. This creates silos that prevent secure, private data verification across platforms.
Platforms control user data, creating walled gardens that prevent interoperability and user control.
Users must surrender personal data to access services, with unclear disclosure and consent practices.
No way to prove data authenticity to third parties without exposing sensitive information.
zkTLS creates a secure bridge between Web2 and Web3, enabling verifiable data transfer while maintaining complete privacy and user control.
zkTLS combines Transport Layer Security with Zero-Knowledge Proofs to enable users to prove statements about HTTPS connections without revealing underlying secrets or sensitive data.
User establishes a standard TLS connection with a web server, creating an encrypted channel for secure data transmission using existing web infrastructure.
The zkTLS system uses various approaches (MPC, TEE, or Proxy) to verify the TLS session and capture cryptographic evidence without compromising security.
The system creates cryptographic attestations about the session, proving data authenticity and integrity while maintaining the confidentiality of sensitive information.
Users generate zero-knowledge proofs that selectively reveal only necessary information while cryptographically proving statements about their data to any verifier.
zkTLS implementations use different architectural approaches, each with unique trade-offs in performance, trust assumptions, and decentralization. Here are the primary implementation models in use today.
Multi-party computation enables multiple parties to collaboratively perform TLS operations without any single entity holding the full session key. Provides strong decentralization guarantees but requires significant computational and networking resources.
Trusted Execution Environments use hardware-enforced secure zones to process TLS handshakes and generate attestations. More efficient than MPC but relies on trusted hardware and manufacturer security guarantees.
Proxy servers act as intermediaries for HTTPS traffic, creating attestations about communication without exposing secrets. Lightweight and computationally efficient but requires trust in the proxy infrastructure.
zkTLS enables secure data verification across industries, empowering businesses and individuals with privacy-preserving solutions.
Verify purchase histories and loyalty points without revealing personal details, improving targeting and rewards programs.
Confirm ownership of social accounts, enhance marketing campaigns, and reduce sybil attacks without exposing identity.
Prove bank balances, credit scores, and income securely, enabling personalized services without compromising privacy.
Verify ownership of digital assets like code, designs, and artwork, protecting against IP theft and fraud.
Verify event attendance, confirm locations, and authenticate reviews, bridging digital and physical worlds.
Secure health record access and telemedicine verification while protecting sensitive patient information.
Opacity Network implements an MPC-based zkTLS solution that allows you to prove data from web servers without exposing details you want to keep private, using distributed multi-party computation for maximum security.
Opacity Network's MPC-based architecture ensures no single party ever holds complete session keys or full access to your data. The network leverages EigenLayer to create a robust economic security model that inherits Ethereum's trust guarantees while ensuring cryptographic accountability.
