Cryptosat

Cryptosat is a space technology company that operates cryptographic and blockchain computing infrastructure on board CubeSat satellites in low Earth orbit. The company places miniaturized computers running cryptographic protocols on small satellites, providing a tamper-proof and physically secure computing environment that is inaccessible to terrestrial attackers. Cryptosat's satellite-based platform enables applications including verifiable randomness generation, threshold signature schemes, and secure key ceremony operations for blockchain networks and cryptographic applications that require a high-assurance trust anchor. The company has launched satellites on SpaceX Transporter rideshare missions and demonstrated the viability of on-orbit cryptographic operations. Cryptosat addresses the growing demand from blockchain ecosystems for cryptographic services that cannot be compromised by the physical security vulnerabilities inherent in ground-based computing infrastructure.
