On January 21, 2026, at the Davos World Economic Forum, WISeKey International and its subsidiary SEALCOIN officially unveiled a world-first space-based, quantum-resistant cryptocurrency transactions executed via a low-Earth-orbit (LEO) satellite constellation.
This development marks a shift from using satellites as mere “relays” to turning them into active, autonomous economic participants in the global “Machine Economy.”
Security in the post-quantum era
The SEALCOIN platform utilizes post-quantum-ready cryptography to secure transactions against the future threat of quantum computing — a risk that has loomed over traditional blockchains for years. By generating and signing cryptographic signatures directly on-board the satellites, the system creates a resilient “execution layer” that is entirely independent of terrestrial internet infrastructure, which is increasingly vulnerable to geopolitical sabotage and cyber warfare.
Empowering the agentic economy
The unveiling demonstrated how AI agents and IoT devices can authenticate and exchange value autonomously using this orbital ledger. This is particularly critical for infrastructure in remote environments where terrestrial connectivity is unreliable. By anchoring identity in space-hardened semiconductors and satellite-based PKI (Public Key Infrastructure), SEALCOIN aims to provide a “sovereign” network for the tokenized economy.
As traditional networks face increased scrutiny and centralizing regulations, the move toward space-based decentralization offers a glimpse into a censorship-resistant future where the “World Computer” literally orbits the planet.
