SpaceComputer Partners with Tropic Square: Open Security Hardware for Orbital Compute

We’re thrilled to announce that SpaceComputer and Tropic Square are entering a partnership. Tropic Square is a Prague-based semiconductor firm building the world's first open-source, auditable secure element (SE). Tropic Square's TROPIC01 chip is being integrated into our Space Fabric hardware design as

Filip Rezabek on Quantum Communications at SmallSat Europe

I'm Filip, one of the co-founders and CTO of SpaceComputer. And today I'll be talking about quantum communications. So it's a short overview of actually where we see the space heading with respect to quantum computing and how can we actually prepare for

In our previous post, we outlined the randomness supply chain and how we can ensure randomness is correctly generated and delivered to the user. But once the user has that randomness, along with proof that it hasn't been tampered with, how does he use it? That’s the

Making Orbitport Verifiable: Reproducible Builds, Docker Hardened Images, and Attested TLS

Introduction In our previous post, Orbitport: The Gateway to Space, we introduced Orbitport as SpaceComputer’s universal gateway between Earth and in-space infrastructure: a developer-friendly API layer that abstracts away ground-station scheduling, intermittent orbital connectivity, satellite-specific integrations, and the operational complexity of communicating with hardware in

Space Infrastructure for Safe Computation: Talk by Filip and Toufic at EthCC

Last week, CoFounder Filip Rezabek and Applied cryptographer Toufic Batrice from the SpaceComputer team attended the Ethereum Community Conference (EthCC) in Cannes, France. They gave a talk 'Stars to Bits: Space Infrastructure for Safe Computation' which focused on the opportunity, challenges, and applications of building in Low Earth

Orbitport: The Gateway to Space

Hello Earthlings! Space computing today feels like a strange split reality: on one hand, we are building a future filled with paradoxes—laser communications beaming data across orbit, moon based hotels, and ambitious timelines for human travel to Mars. On the other hand, much of our actual interaction with space
