Cryptosat develops tamper‑proof orbital compute modules that physically separate computing units to mitigate side‑channel attacks that affect traditional TEEs (such as Intel SGX). The company says physically unreachable satellites make many attack vectors far harder to exploit. Its use cases include transaction signing, trusted setups for cryptographic schemes, a randomness oracle, and a time‑oracle (VDF). In May Cryptosat launched Crypto1, a coffee‑mug‑sized proprietary crypto‑satellite, on SpaceX’s Transporter 5 Falcon 9 mission. The module is described as a tamper‑proof platform intended to host a range of blockchain-based applications, products, and services. The company is led by seasoned space and security tech entrepreneurs Yonatan Winetraub and Yan Michalevsky and recently raised a seed financing to support its development.
