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 orbit. That first version

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

SpaceComputer Secure Key Management Services Beyond the Cloud

Key management services (KMSs) are foundational to modern cryptographic infrastructure. At SpaceComputer we are building KMS services beyond terrestrial cloud infrastructure.

𝕤𝕡/𝕒𝕔𝕔 | The SpaceComputer Roadmap

𝕤𝕡/𝕒𝕔𝕔 = the movement from merely virtual decentralization to physically verifiable, orbital security primitives–an architectural shift toward space-native trust minimization. Consequential to our ongoing efforts on research and engineering with our initial security service product (cTRNG), we are ecstatic to reveal the official 𝕤𝕡/𝕒𝕔𝕔 roadmap. This marks the next chapter in our
