- SpaceTEE Confidential Compute: Trusted execution environment services running on satellites for confidential AI inference, classified data processing, and multi-party computation. Targets financial services, healthcare, defense organizations requiring verifiable proof of where and how data was processed.
- Randomness Beacon: Public and private randomness beacon services delivering verifiable tamper-proof randomness from orbit. Public beacon is open access; private beacon offers dedicated service with guaranteed throughput and SLA.

SpaceComputer product offering
Product offeringCore offering
SpaceComputer builds and operates a satellite-based distributed computing network that delivers tamper-resistant confidential compute, verifiable true random number generation, and orbital key management services to developers and enterprises. Customers consume these services through the Orbitport REST API, which provides access to SpaceTEE (trusted execution in orbit), cTRNG (entropy sourced from cosmic rays), an AWS KMS-compatible key management service, and a two-tier blockchain settlement architecture (Celestial L1 in orbit and Uncelestial L2 on Earth).
Product overview
SpaceComputer is building a distributed satellite network that enables censorship-resistant compute and verifiable settlement across Earth and orbit, combining a space-native compute layer with a two-tier blockchain architecture. The core product portfolio centers on Space Fabric — the foundational hardware and software security architecture — which provides the trust layer for all orbital services. Key products include Orbitport (the API gateway for consuming orbital services), SpaceTEE (satellite-hosted trusted execution environments for confidential workloads), cTRNG (cosmic true random number generation sourced from cosmic ray entropy), KMS (orbital key management with threshold cryptography and on-orbit key generation), and the Randomness Beacon (public/private verifiable randomness from orbit). The two-tier blockchain consists of Celestial L1 (orbital settlement and consensus layer) and Uncelestial L2 (high-throughput Earth-based execution layer). Security services also include Co-Processing and Proof of Location. All services are accessible via the Orbitport REST API.

SpaceComputer competitors and assessment
Company assessmentBroad incumbents
- HashiCorp Vault: HashiCorp Vault is the dominant enterprise key management and secrets management platform, directly competing with SpaceComputer's orbital KMS offering. While Vault is terrestrial and software-based, it represents the incumbent solution SpaceComputer must displace for enterprise security budgets.
- Fireblocks: Fireblocks is a digital asset custody and key management platform serving banks, trading firms, and crypto institutions. It overlaps with SpaceComputer's target financial services customers seeking secure key management for digital assets, and represents a comparison point for institutional-grade MPC and HSM-based security.
- AWS Key Management Service (KMS): AWS KMS is the largest cloud-native key management service and SpaceComputer explicitly offers an AWS KMS-compatible API. AWS KMS represents the benchmark incumbent solution that SpaceComputer must position against for enterprise security workloads requiring HSM-grade functionality.
Direct peers
- Secret Network: Secret Network is a blockchain with TEE-based confidential smart contracts, competing with SpaceComputer for privacy-preserving DeFi and enterprise workloads. Both companies target similar blockchain developer audiences seeking verifiable computation, though Secret Network operates entirely on terrestrial TEEs.
- Phala Network: Phala Network is a TEE-based confidential smart contract blockchain that uses Intel SGX to provide verifiable off-chain computation. It directly competes with SpaceComputer's SpaceTEE offering for confidential compute workloads, though Phala is terrestrial-only versus SpaceComputer's orbital positioning.
- CryptoSat: CryptoSat pioneered secure and tamper-proof computing in space using CubeSats with TEE capabilities, and is the closest direct comparable to SpaceComputer in satellite-based confidential compute. SpaceComputer advisor Yan Michalevsky co-founded CryptoSat, making it both a peer and a potential ecosystem collaborator.
- SpaceChain: SpaceChain builds blockchain infrastructure deployed on satellites, with similar positioning of putting cryptographic and decentralized infrastructure in orbit. While SpaceChain focuses more on multisig and node operation, both companies share the space-blockchain thesis and target overlapping DeFi and enterprise customers.
Emerging players
- Nillion: Nillion is building decentralized blind computation using MPC and other techniques to enable processing of encrypted data without decryption. It targets similar confidential compute use cases for AI and enterprise data, intersecting with SpaceComputer's SpaceTEE and KMS offerings as an alternative architectural approach.
- Aleo: Aleo is a zero-knowledge proof-based blockchain that enables private computation and decentralized applications. It competes with SpaceComputer for confidential compute workloads in the Web3 ecosystem, using ZK proofs as an alternative to TEE-based approaches for verifiable computation.
- Andromeda Space (Andra Space): Andra Space / Andromeda is an emerging satellite infrastructure startup in the orbital compute space, partially overlapping with SpaceComputer's satellite-as-a-service positioning. Both target decentralized infrastructure use cases leveraging LEO satellites.

Frequently asked questions about SpaceComputer
What does SpaceComputer do?
SpaceComputer builds and operates a satellite-based distributed computing network that delivers tamper-resistant confidential compute, verifiable true random number generation, and orbital key management services to developers and enterprises. Customers consume these services through the Orbitport REST API, which provides access to SpaceTEE (trusted execution in orbit), cTRNG (entropy sourced from cosmic rays), an AWS KMS-compatible key management service, and a two-tier blockchain settlement architecture (Celestial L1 in orbit and Uncelestial L2 on Earth).
Is SpaceComputer a public or private company?
SpaceComputer is a private company. It is classified as venture growth investor backed and is currently operating.
When was SpaceComputer founded?
SpaceComputer was founded in 2024. It employs 1 to 10 people.
Where is SpaceComputer based?
SpaceComputer is headquartered in Singapore, Singapore, in the Asia region.
How does SpaceComputer make money?
Four revenue lines are on record. cTRNG API Access are the primary driver. The others are key Management Service (KMS), spaceTEE Confidential Compute and randomness Beacon.
Who are SpaceComputer's main competitors?
Broad incumbents on record are HashiCorp Vault, Fireblocks and AWS Key Management Service (KMS). Direct peers are Secret Network, Phala Network, CryptoSat and SpaceChain. Emerging players are Nillion, Aleo and Andromeda Space (Andra Space).
Does SpaceComputer have an API?
Yes. REST API providing access to orbital services including cTRNG (cosmic True Random Number Generation) and spaceTEE (Trusted Execution from orbit). The API supports source selection and fallback chain: primary source 'aptosorbital' for direct satellite-generated cosmic random data, secondary 'derived' for BIP32 hierarchical key derivation from cosmic master seed, and public IPFS beacon published every 60 seconds. Authentication uses OAuth2 via Auth0 (Auth0 handles token issuance and refresh; the SDK manages token lifecycle automatically). The TypeScript SDK (@spacecomputer-io/orbitport-sdk-ts) implements the fallback chain automatically for a single-call experience. The IPFS beacon requires no authentication. Developer documentation is at docs.spacecomputer.io.
