- WISeSat.Space satellite launch adds post-quantum identity support for IoT devices worldwide.
- Hedera provides reliable audit logs and low-cost transfers for automated device activity.
SEALSQcorp, a subsidiary of WISeKey, is preparing to launch an upgraded WISeSat.Space satellite via SpaceX on November 19. The program promotes machine identity for connected devices around the world by coupling space-based broadcasts with hardware-level identification.
Hedera Hashgraph acts as the trust layer that anchors identity states for large-scale automated interactions between networks.
SEALSQ uses the QS1 chip to determine the identity of devices at the silicon level. The chip creates tamper-proof credentials, secures keys in a protected element, and supports algorithms intended to withstand post-quantum threats. This hardware-based identity approach blocks tampering and protects connected devices at scale around the world.
Public authentication can be achieved through decentralized identifiers (DIDs) and verifiable credentials (VCs). These standards enable identity proofing without exposing private keys. This approach provides a uniform method for authenticating connected devices across regions, allowing networks to establish a consistent, secure way to verify trust.
SpaceX launches post-Quantum IoT identity – and #Hedera is the trust layer behind it
On November 19, @SEALSQcorp (a subsidiary of @WISeKey) will launch an upgraded https://t.co/Q1uFGLPcZu satellite with @SpaceX.
This is not “just a satellite.”

WISeSat.Space Connects devices all over the Earth
WISeSat.Space extends identity delivery beyond ground networks. The service broadcasts updates across continents, supports device enrollment in remote zones, and enables continuous state synchronization. The network provides global availability for connected equipment with limited terrestrial access.
Satellite connections enable secure machine-to-machine messaging, allowing industrial operators, government agencies and power systems to verify the identity of devices in real time. As billions of connected units join communications networks, the demand for stronger identification grows.
Once authenticated, devices initiate automated swaps that handle data transfers, access signals, supply chain synchronization, and power distribution. Usage-based services and bandwidth payments rely on identity data stored in immutable audit layers.
Hedera’s role in machine-driven transactions
Hedera Hashgraph enters this structure as the foundation of trust for machine communications. The blockchain acts as the distributed verification layer and anchors all identity statuses and audit records. The consensus service produces time-stamped proofs so that every transaction between machines remains verifiable, immutable and low-cost.
SEALCOIN, a digital transaction layer built on Hedera, handles the exchange between devices. This setup supports automated payments, data access permissions, supply chain signaling, and pay-per-use services. Hedera’s high throughput and fractional transaction fees enable machine-to-machine payments to take place instantly and securely at scale.
The partnership brings together secure identity, satellite coverage and a public ledger. Each layer supports secure machine interaction across boundaries. Hedera acts as a layer of trust, as confirmed in the statement
Hedera is not for speculation; Hedera is for machine trust.
