The Orbital Root of Trust
SpaceComputer
A tamper-proof, satellite-based blockchain delivering trusted execution, cryptographic services, and confidential compute from orbit. Physically isolated from terrestrial threats, resilient to side-channel attacks, and resistant to state-level adversaries.
Solutions
Orbital infrastructure for security-critical applications
Secure Gateway
Establish authenticated channels with orbital nodes through a distributed ground station network. Simplifying access to space infrastructure for developers and enterprises.
Randomness
True random numbers harvested from cosmic radiation detected via satellite instrumentation. Cryptographically signed at source for verifiable, unbiased entropy.
Key Management
Orbital hardware security modules on satellite nodes provide leak-proof key custody. Secrets are physically unreachable and immune to side-channel extraction.
Confidential Compute
SpaceTEE delivers trusted execution with physical isolation no terrestrial environment can match. Compute over encrypted data with forward secrecy guarantees.

Coming SoonOrbital Key Management Service backed by satellite HSMs. Threshold signing, secure custody, and key derivation in a physically tamper-proof environment.
Two-Tier Architecture
SpaceComputer runs a Celestial L1 consensus network in orbit using satellite nodes connected via the Iridium mesh network. An Uncelestial L2 on Earth provides low-latency sequencing with fast pre-finality, while the orbital layer serves as the ultimate root of trust.
- Celestial L1 — BFT consensus among satellite nodes with HotStuff-based protocol
- Uncelestial L2 — Earth-side sequencing with pre-finality and rollup settlement
- Physical isolation — Nodes in orbit are tamper-proof by any administrator or state actor
- Forward secrecy — Secrets cannot be extracted via side-channel attacks, now or in the future
Start Building
Access cosmic randomness in seconds with the Orbitport SDK or direct API calls
import { OrbitportSDK } from "@spacecomputer-io/orbitport-sdk-ts";
// Initialize (works without credentials via IPFS)
const sdk = new OrbitportSDK({ config: {} });
// Get cosmic randomness
const result = await sdk.ctrng.random();
console.log("Random:", result.data.data);# No authentication needed with IPFS beacon
