Abstract
The emergence of decentralized satellite networks and orbital computing platforms creates a pressing need for trust architectures that can operate without physical access to the hardware, without reliance on pre-provisioned vendor secrets, and without dependence on a single manufacturer’s attestation service. We present Space Fabric, an architecture that provides the missing trust foundation for orbital computing by relocating the trusted computing stack to satellite infrastructure, exploiting a satellite’s post-launch physical inaccessibility as a tamper barrier unattainable by terrestrial deployments.

Frequently Asked Questions
Space Fabric’s most commonly asked questions, answered!
Space Fabric is our satellite-native trusted computing architecture. It provides a verifiable trust layer for secure computation in orbit by relocating the trusted computing stack to satellite infrastructure, exploiting a satellite’s post-launch physical inaccessibility as a tamper barrier unattainable on Earth. It addresses two fundamental gaps in existing trusted computing: the physical access gap, where any chip on Earth can eventually be reached and tampered with, and the root-of-trust gap, where existing attestation chains depend on vendor-provisioned secrets that cannot be independently audited.
