On January 21, 2026, at the Davos World Economic Forum, WISeKey International and its subsidiary SEALCOIN officially announced the world’s first space-based quantum-resistant cryptocurrency transaction conducted via a constellation of low-Earth orbit (LEO) satellites.
This development marks a shift from using satellites as mere “transponders” to turning them into active, autonomous economic participants in a global “machine economy”.
Security in the post-quantum era
The SEALCOIN platform leverages post-quantum-enabled cryptography to protect transactions from the future threats of quantum computing, risks that have long loomed over traditional blockchains. By generating and signing cryptographic signatures directly on the satellite, the system creates a resilient “execution layer” that is completely independent of terrestrial internet infrastructure, which is increasingly vulnerable to geopolitical sabotage and cyber warfare.
Powering the agent economy
In this presentation, we demonstrated how AI agents and IoT devices can use this orbital ledger to authenticate and exchange value autonomously. This is especially important for infrastructure in remote environments where ground connectivity is unreliable. SEALCOIN aims to provide a “sovereign” network for the tokenized economy by anchoring identity in a space-proof semiconductor and satellite-based PKI (Public Key Infrastructure).
As traditional networks face increased surveillance and centralization of regulation, the move toward space-based decentralization offers a glimpse into a censorship-proof future in which the “World Computer” literally orbits the Earth.
