ETHWarsaw 2025

Orest Tarasiuk

Hi, I’m Orest — a computer scientist focused on scaling Ethereum.

I’m the co-founder of t1, the first interop rollup. It introduces real-time proving (RTP) to fix fragmentation and composability challenges in scaling Ethereum. Trusted Execution Environments (TEE) are used to prove the integrity of t1 execution to Ethereum in less than 12 seconds. By running partner rollup nodes in its node infrastructure, t1 aggregates and proves their state to Ethereum in real-time. As a result, t1 enables instant settlement between any combination of partner rollups and Ethereum, creating the much-needed cross-chain application and liquidity infrastructure, today.

Background:
- Co-founder, zkWarsaw — A Warsaw-based community advancing zero-knowledge research through lectures and workshops for researchers, builders, and hackers.
- Engineer, Scroll — Helped build a bytecode-compatible zkEVM to scale Ethereum with strong EVM equivalence.
- Co-founder, Cara Care — Developed digital tools to support people living with chronic digestive diseases.
- Co-founder, Knit — Created an app for hosting structured, video-based networking experiences.

Beyond crypto and code, I’m passionate about great coffee, ski touring, motorcycling, horseback riding, and blues & balfolk dance.
