6 terms

post-quantum technical

"SEALSQ’s Post-Quantum chip, and SEALCOIN wallet directly onboard"

Post-quantum describes technology, especially encryption methods, designed to stay secure against powerful future quantum computers that could break today’s digital locks. For investors, it signals which products, services or suppliers are preparing for a major shift in cybersecurity risk—similar to choosing a safe built to resist a new kind of drill—affecting costs, liability, competitive advantage and regulatory compliance across industries.

root of trust technical

"embedding WISeKey’s trusted Root of Trust, with SEALSQ’s Post-Quantum chip"

A root of trust is a small, tamper-resistant component inside a device or system that serves as the secure anchor for identity and data protection—think of it as a locked safe that holds the master keys and proof that the system is genuine. It matters to investors because a strong root of trust reduces the risk of hacks, supports regulatory compliance and customer confidence, and therefore can protect a product’s value and a company’s reputation.

depin technical

"decentralized physical internet with DePIN technology and house the development"

Decentralized physical infrastructure networks (DePIN) are systems where many independent participants use digital tokens and open software to build, operate and maintain real-world hardware such as wireless hotspots, sensors, or storage nodes. For investors, DePINs matter because they create new ways to fund and earn from physical services without a single company in control—similar to a community-owned utility where contributors are rewarded for providing and maintaining equipment, which can affect token value, service adoption, and regulatory risk.

post-quantum cryptography technical

"architecture protected by post-quantum cryptography."

Post-quantum cryptography is a set of new methods for scrambling data so it stays secure even if powerful quantum computers exist; think of replacing today’s locks with designs that a future high‑speed lockpicker cannot open. For investors, it matters because companies must upgrade systems, meet regulations, and protect customer and trade data—creating costs, competitive advantages, or legal and reputational risks depending on how quickly and effectively they adopt these new security standards.

spac financial

"via a business combination with Columbus Acquisition Corp. (Nasdaq: COLA), a Cayman Islands–based public SPAC"

A special purpose acquisition company (SPAC) is a company formed specifically to raise money through an initial public offering (IPO) with the goal of buying or merging with an existing private company. For investors, a SPAC offers a way to invest in a potential future business without initially knowing which company it will acquire, making it a way to access new investment opportunities that might otherwise be difficult to invest in directly.

distributed ledger technology technical

"Built on Hedera’s Decentralized Ledger Technology, SEALCOIN tokens ensure secure"

A distributed ledger technology is a way of storing a shared digital record of transactions across many independent computers so no single party controls or can silently alter it — imagine the same accounting ledger kept in multiple filing cabinets that all must agree before any entry is changed. For investors it matters because it can reduce fraud, speed up settlement, cut middleman costs and enable new kinds of tradable assets, all of which can affect a company’s costs, revenue models and regulatory exposure.

WISeKey’s WISeSat Schedules Launch of Its 21^st LEO Satellite with SpaceX from California for March 2026

WISeSat Teams with SEALSQ and SEALCOIN.AI for an Exceptional Opportunity to Accelerate Its Vision for the Space Quantum Internet, Delivering Quantum-Secure, High-Speed, Low-Latency Broadband Directly to Users via a Constellation of LEO Satellites

Geneva, Switzerland, February 11, 2026 – WISeKey International Holding Ltd (“WISeKey”) (SIX: WIHN, NASDAQ: WKEY), a leading global cybersecurity, blockchain, and IoT company, today announces that its subsidiary WISeSat.Space Corp. (“WISeSat”) specialized in space-technology and secure satellite communications for IoT applications is preparing for the launch of its 21^st LEO satellite. The launch is currently scheduled for the end of March from California with SpaceX.

For this new launch, WISeSat is teaming with two other WISeKey subsidiaries: SEALSQ Corp (Nasdaq: LAES), which focuses on semiconductors, PKI, and post-quantum technology products and, SEALCOIN.AI which focuses on decentralized physical internet with DePIN technology and house the development of the SEALCOIN platform.

Together, all parties aim to extend previous Proofs of Concept by embedding WISeKey’s trusted Root of Trust, with SEALSQ’s Post-Quantum chip, and SEALCOIN wallet directly onboard the WISeSat platform, thus accelerating their vision for the space quantum internet, by delivering quantum-secure, high-speed, low-latency broadband via a via constellation of LEO satellites. The satellites also integrate incremental innovations derived from SEALSQ’s quantum roadmap, leveraging advances from its partner ecosystem and startup investment program to enhance security, performance, and operational efficiency.

This upcoming launch represents the first operational deployment of a new generation of WISeSat satellites, which will progressively populate and modernize its constellation. With an average satellite lifespan of approximately five years, continuous renewal is essential to integrate new technologies, improve performance, and introduce advanced functionalities.

The anticipated WISeSat listing on NASDAQ via a business combination with Columbus Acquisition Corp. (Nasdaq: COLA), a Cayman Islands–based public SPAC, will provide access to capital markets which is expected to significantly accelerate the deployment of the constellation, enabling global, device-to-device secure connectivity. This infrastructure will allow IoT devices equipped with WISeKey and SEALSQ microchips to securely transact tokens directly with Earth-based devices. Over time, quantum-enhanced capabilities will be gradually integrated into the satellite network.

WISeSat Satellite Deployment Strategy
As the satellite IoT communications division of WISeKey, WISeSat was created to address the growing demand for secure, real-time connectivity across critical sectors including logistics, agriculture, energy, and infrastructure management. Traditional IoT networks face increasing vulnerabilities, and WISeSat mitigates these risks through a global, satellite-based architecture protected by post-quantum cryptography.

Building on the success of previous missions, WISeKey is planning multiple WISeSat deployments throughout 2026, focused on expanding constellation coverage, increasing bandwidth and redundancy, integrating AI-driven analytics for enhanced security monitoring and real-time data processing, and developing hybrid terrestrial-satellite architectures.
