WISeKey plans space-based quantum-resistant crypto platform reveal

WISeKey International Holding Ltd (NASDAQ: WKEY) announced plans to unveil SEALCOIN, a space-based cryptocurrency transaction platform, at an event in Davos on January 21, 2026.

The platform uses WISeSat's low-Earth-orbit satellite constellation to execute blockchain transactions through space infrastructure rather than terrestrial networks. The system incorporates post-quantum cryptographic signatures generated directly onboard satellites, according to the company's press release.

SEALCOIN enables satellites to store data, validate transactions, enforce access policies, and deliver encrypted payloads to authenticated devices on Earth. The platform targets AI agents, IoT devices, and critical infrastructure systems operating in areas with limited terrestrial connectivity.

The company stated that satellites within the SEALCOIN ecosystem will generate quantum-resistant signatures using post-quantum algorithms at the hardware level. This addresses potential harvest-now-decrypt-later attacks and provides security for orbital systems that cannot receive cryptographic updates.

The platform operates using the QAIT token as its native utility and payment instrument for machine authentication, transaction settlement, and economic coordination across terrestrial and space-based systems. QAIT plans a Token Generation Event in Q1 2026 with listings on tier-one exchanges.

WISeKey's subsidiaries include SEALSQ Corp (NASDAQ: LAES) for semiconductors and post-quantum technology, WISeSat AG for space technology, and SEALCOIN AG for decentralized internet infrastructure development.

The cybersecurity and IoT company reports having deployed over 1.6 billion microchips across various sectors and operates through multiple subsidiaries specializing in digital identity, blockchain, and space communication technologies.
