- WISeSat.Space satellite launch adds post-quantum identity support for IoT devices worldwide.
- Hedera provides proof audit logs and low-cost transfers for automated device activity.
SEALSQcorp, a subsidiary of WISeKey, is gearing up to launch an enhanced WISeSat.Space satellite on November 19 through SpaceX. The initiative advances machine identity for connected devices globally by combining space-based transmissions with hardware-level identification.
Hedera Hashgraph acts as the trust layer anchoring identity states for large-scale automated interactions across networks.
SEALSQ deploys the QS1 chip to establish device identity at the silicon level. The chip generates unforgeable identifiers, secures keys within a protected element, and supports algorithms designed to withstand post-quantum threats. This hardware-centric identity approach prevents tampering and safeguards connected devices on a global scale.
Public verification can be achieved through decentralized identifiers (DIDs) and verifiable credentials (VCs). These standards enable identity verification without exposing private keys, offering a unified method for authenticating connected devices across regions and establishing a consistent, secure way to validate trust within networks.
SpaceX Launches Post-Quantum IoT Identity — and #Hedera Is the Trust Layer Behind It

WISeSat.Space Connecting Devices Across Earth
WISeSat.Space extends identity delivery beyond ground networks, broadcasting updates across continents, facilitating device enrollment in remote areas, and enabling continuous state synchronization. The network offers global availability for connected equipment with limited terrestrial connectivity.
Satellite links enable secure machine-to-machine communication, allowing industrial operators, public agencies, and energy systems to verify device identity in real-time. With billions of connected devices joining communication networks, the need for robust identification is on the rise.
Following verification, devices initiate automated exchanges for data transfers, access permissions, supply chain synchronization, and energy distribution. Usage-based services and bandwidth payments rely on identity records stored in immutable audit layers.
Hedera’s Role in Machine-Driven Transactions
Hedera Hashgraph plays a vital role in machine communication, serving as the distributed verification layer that anchors all identity states and audit trails. Its consensus service produces time-stamped proofs, ensuring verifiability, immutability, and cost-effectiveness in every machine transaction.
SEALCOIN, a digital transaction layer built on Hedera, facilitates exchanges between devices, supporting automated payments, data access controls, supply chain notifications, and pay-per-use services. With Hedera’s high throughput and minimal transaction fees, machine-to-machine payments can occur securely and instantly at scale.
The collaboration integrates secure identity, satellite coverage, and a public ledger, fostering safe machine interactions across borders. Hedera functions as the trust layer, as emphasized in the statement
Hedera is not for speculation —Hedera is for machine trust.
