Rockstar🎓
Top SchoolNazar Mokrynskyi is a blockchain protocol researcher and co-founder with 13 years of software engineering experience, currently researching next‑gen protocol design at the Subspace Foundation. He blends low‑level Rust systems work with TypeScript and WebAssembly prototyping, having implemented core Subspace components on Parity Substrate and optimized encoding/farming with AES‑NI (VAES) intrinsics and OpenCL experiments. An active open‑source contributor, his footprint spans paritytech/substrate, polkadot‑js, emscripten and a wide set of frontend and networking projects—showing fluency from cryptography and networking to UI polish. Before research he led large‑scale backend efforts at Restream, consistently delivering performance and reliability improvements across streaming infrastructure. Based in Ukraine, he prefers shipping pragmatic, measurable engineering over academic abstraction and keeps much of his work public on GitHub.
