Shared core model, dependencies and utilities for ChainMetric blockchain and IoT powered supply chain solution

Hey! I'm Timofey

I am an enthusiastic researcher in cryptography and distributed systems, who enjoys sharing his knowledge and neat findings 🤓 I design blockchain-oriented protocols and develop web3 infrastructure 🏗️

There are many things that I find interesting, but if picking those I focus on most, then it would be:

• 1️⃣ verifiable and private computation with ZK and MPC
• 2️⃣ secure blockchain scaling with data-availability sampling (DAS)
• 3️⃣ chain and network layer privacy.

I find inspiration from 👥 talking with open-minded people, 🎨 spectating different kinds of modern digital art, and 🪐 discovering science and mysteries of our universe. 👉 I value open-source, rights to privacy, and simple human kindness 🤗
