WISeKey International Holding Ltd. is set to redefine cryptocurrency security with the unveiling of SEALCOIN at Davos 2026 on January 21st. The company, a leader in cybersecurity and IoT, will demonstrate a new crypto and machine-economy infrastructure extending transactions into orbit using its WISeSat.Space satellite constellation. This platform moves beyond terrestrial networks, leveraging space-based hardware and “post-quantum-ready cryptography” to secure blockchain transactions. WISeKey is pioneering a world-first by integrating quantum-resistant cryptographic signatures generated directly onboard satellites, addressing future threats and establishing a resilient foundation for AI, IoT, and critical infrastructure—a system where “satellites can securely store data, validate transaction outcomes, enforce access policies, and deliver encrypted payloads.”
WISeSat Space Constellation Enables Quantum-Resistant Transactions
A new approach to securing digital transactions is emerging, extending beyond terrestrial networks and into low-Earth orbit via the WISeSat constellation. WISeKey International Holding Ltd is unveiling the SEALCOIN platform at Davos 2026, designed to execute and enforce blockchain-based transactions utilizing space infrastructure. This isn’t simply about relaying signals; the system envisions satellites as “active economic participants,” capable of far more than passive connectivity. The SEALCOIN ecosystem allows satellites to perform critical functions including secure data storage, transaction validation, access policy enforcement, and the delivery of encrypted payloads directly to devices on Earth. This distributed architecture addresses vulnerabilities inherent in ground-based systems, particularly in environments with limited or unreliable connectivity. WISeSat’s hardware-rooted trust and post-quantum-ready cryptography are central to this resilience, moving beyond existing capabilities to establish satellites as secure anchors for the machine economy. “Infrastructure for the machine economy,” is how WISeKey describes the platform, built on quantum-resistant semiconductors, satellites, and distributed ledgers. A key advancement is the integration of quantum-resistant cryptographic signatures generated onboard the satellites themselves. This capability, described as a “world-first,” will allow satellites to sign transactions using post-quantum algorithms at the hardware level. This addresses the long-term threat of “harvest-now-decrypt-later” attacks, recognizing the need for orbital systems to remain secure for years without requiring cryptographic updates. The QAIT token serves as the native utility and payment instrument within the SEALCOIN network, used for machine authentication, transaction settlement, and coordination of activity across both terrestrial and space-based systems. The platform’s rollout is linked to revenue-driven demand, leveraging an existing client base within the WISeKey Group. “As these customers use SEALCOIN-enabled services for device authentication, data exchange, and space-to-ground transactions, the revenues generated from these services create direct transactional demand for QAIT,” the company states. A Token Generation Event (TGE) for QAIT is planned for Q1 2026, with listings on tier-one exchanges.
SEALCOIN Platform Integrates Semiconductors, Satellites, and Ledgers
WISeKey is pioneering a novel infrastructure marrying hardware security with orbital assets through the SEALCOIN platform, unveiled at Davos 2026. This system transcends traditional terrestrial blockchain networks, establishing a distributed ledger system bolstered by a low-Earth-orbit satellite constellation operated by WISeSat.Space. Leveraging WISeSat’s capabilities, SEALCOIN isn’t merely relaying data; it’s enabling satellites to actively participate in economic transactions, securely storing data, validating outcomes, and enforcing access policies directly from orbit. The platform’s architecture is built on a tri-fold foundation: certified semiconductor security employing PKI-based digital identities, distributed ledger settlement, and crucially, post-quantum-ready cryptographic foundations. This combination allows for autonomous machine-to-machine value exchange, even in environments lacking reliable terrestrial connectivity. “Infrastructure for the machine economy,” describes WISeKey, highlighting the platform’s ambition to facilitate a future of interconnected, self-governing devices. This next phase of collaboration aims to create a “world-first quantum-resistant signature issued from space,” addressing the long-term security threats posed by potential “harvest-now-decrypt-later” attacks. By generating signatures at the hardware level within the satellite, the system aims to maintain security for years without requiring potentially disruptive cryptographic retrofits. Importantly, SEALCOIN is grounded in existing client relationships within the WISeKey Group, with revenue generated from services directly driving demand for the QAIT token, creating a network fueled by real-world usage.
QAIT Token Fuels Machine Economy & Network Access
The emergence of a truly decentralized machine economy hinges on secure, reliable transaction infrastructure – and WISeKey is positioning the QAIT token as a key component. Unlike many cryptocurrencies focused on human-to-human exchange, QAIT is specifically designed for “machine-scale usage,” though accessibility for investors seeking exposure to this infrastructure is planned through listings with tier-one exchanges. This isn’t merely about creating another digital currency; it’s about establishing a system where devices can autonomously coordinate and exchange value. The architecture is intended to function “wherever machines operate, including in space,” addressing limitations of traditional, ground-based networks. Crucially, the demand for QAIT is being directly linked to real-world service usage. WISeKey leverages an existing client base within its group of subsidiaries—deploying secure semiconductors, digital identity, IoT and space infrastructure—to drive revenue.
Davos 2026 Launch: Infrastructure for Durable Crypto Networks
The company, in cooperation with subsidiaries SEALCOIN and WISeSat.Space, will demonstrate a platform where crypto transactions, identity verification, and security protocols extend into Earth orbit. This isn’t merely about improving signal transmission; the system actively utilizes satellites as “active economic participants,” fundamentally altering the landscape of blockchain technology. Leveraging WISeSat’s low-Earth-orbit satellite constellation, secured with hardware-rooted trust and post-quantum-ready cryptography, the SEALCOIN platform facilitates blockchain transactions executed and enforced via space infrastructure. This builds upon previously established satellite-based transaction capabilities, extending them into the realm of post-quantum security, designed to combat long-term threats like harvest-now-decrypt-later attacks. WISeKey positions SEALCOIN as a response to a “structural shift underway in global technology markets,” converging semiconductors, space infrastructure, and quantum-resistant security.
Leveraging WISeSat’s operational low-Earth-orbit satellite constellation, secured with hardware-rooted trust and post-quantum-ready cryptography, SEALCOIN platform enables blockchain-based transactions to be executed and enforced using space infrastructure rather than relying solely on terrestrial networks.
