Building Online Trust, On-Chain - Maciej Kalka - zkTLS Day @ Devconnect 2025 (Buenos Aires)

Duration: 00:32:45

Speaker:

Type: Talk

Expertise:

Event: Devcon

Date: Feb 2026

Building Online Trust, On-Chain (Maciek Kalka, vlayer) Join Maciej from vlayer for a deep dive into how zkTLS web proofs can power Ethereum ecosystem. This session explores the emerging design space of on-chain attestations - from cryptographic verification and the oracle problem to evolving trust assumptions in decentralized systems. Drawing on lessons from building zk tooling and infrastructure for practical web proofs, Maciej will highlight the promising directions for verifiable web data - and the approaches intentionally left behind along the way.

InfoFi: ZKTLS and ZKVM Powered Social Leaderboard - Michael Dong - zkTLS Day @ Devconnect 2025

InfoFi without Doxxing: The first ZKTLS and ZKVM Powered Social Leaderboard (Michael Dong, Brevis) Brevis combines zkTLS for verifiable Web2 data with a high-performance zkVM (Pico) to privately compute eligibility for incentive programs. In the Brevis Yapper Leaderboard on Kaito, users prove social identity and on-chain behavior without exposing wallets or trusting operators — enabling rewards and multipliers based on verified credentials, fully private end-to-end.

Instant Payment Liquidity via zkTLS Deposit Proofs - Ricardo - zkTLS Day @ Devconnect 2025

Instant Payment Liquidity via zkTLS Deposit Proofs (Ricardo, Mansa) Mansa enables instant liquidity access by proving deposit completion via zkTLS, storing proofs immutably on IPFS, and optionally attesting on-chain via Ethereum Attestation Service (EAS). This transforms T+3 settlement into instant liquidity access, replacing bilateral trust with verifiable on-chain reputation. Built with vlayer for zkTLS web proofs, Mansa demonstrates how cross-border payment infrastructure can compress time—turning capital that waits into capital that moves.

Proof of Humanity from Web Accounts - Mikhail - zkTLS Day @ Devconnect 2025

Proof of Humanity from Web Accounts (Mikhail, Bring ID) Bring ID uses MPC-TLS to privately verify online activity — for example, confirming a user has completed at least one Uber trip — as a basis for proof of personhood. Built with TLSNotary, it achieves more efficient, privacy-preserving, and trustworthy Sybil-resistance across blockchain ecosystems.

The Cryptography behind zkTLS - Xiang Xie - zkTLS Day @ Devconnect 2025 (Buenos Aires)

Cryptography of zkTLS (Xiang Xie, Primus Labs) Dive into the cryptographic foundations that make zkTLS possible with Xiang Xie, one of the leading minds behind protocols like Ferret, QuickSilver, and modern advances in Oblivious Transfer and Garbled Circuits. This session will unpack the building blocks and explore how these primitives power practical, privacy-preserving zkTLS. Whether you’re a cryptography enthusiast or a developer curious about the math behind zkTLS, this talk will illuminate how cutting-edge research translates into real-world privacy infrastructure.

TLShare: Verifiable Inputs for Private Computation - Dimitris Mouris - zkTLS Day @ Devconnect 2025

TLShare: Verifiable Inputs for Private Computation (Dimitris Mouris, Nilion) TLShare extends zkTLS to enable verifiable, provenance-attested data to be securely imported into multiparty computation (MPC) and fully homomorphic encryption (FHE) workflows. It allows multiple clients to use authentic TLS-sourced data (e.g., from banks, exchanges, etc.) in privacy-preserving analytics, as well as AI model inference and training. Developed jointly by Nillion and Primus Labs, TLShare bridges the gap between verifiable web data and downstream private computation. The talk will also introduce tickr.app, a production deployment showcasing privacy-preserving computation on zkTLS-extracted data using trusted execution environments (TEEs).
