Geneva, Switzerland, January 17, 2025 -- WISeKey International Holding Ltd (“WISeKey”), a leading global cybersecurity, blockchain, and IoT company, today announces the groundbreaking integration of its SEALCOIN with the WISeSAT satellite platform. This innovative development allows secure, decentralized cryptocurrency transactions to be processed via low-orbit satellites, marking a significant leap in global financial inclusion and blockchain infrastructure. Of note, both entities are subsidiaries of WISeKey: SEALCOIN AG focuses on decentralized physical internet with DePIN technology and house the development of the SEALCOIN platform, while WISeSat AG focuses on space technology for secure satellite communication, specifically for IoT applications.

The integration leverages WISeSAT satellites secured by SEALSQ’s VIC-408 secure semiconductor technology, allowing them to function as blockchain nodes in orbit to validate, store, and secure SEALCOIN transactions. Users can initiate transactions through secure wallets or IoT-enabled devices. These transactions are securely transmitted to WISeSAT satellites using ground stations or IoT protocols, where they are validated using blockchain consensus mechanisms. The satellites then broadcast the validated transactions to the global blockchain network, ensuring rapid and secure updates to the distributed ledger.

This technology is especially impactful in remote regions without traditional internet access, where WISeSAT’s satellite coverage provides reliable connectivity. Additionally, the platform enables IoT devices to autonomously execute microtransactions, supporting applications such as smart agriculture, industrial automation, and logistics. In disaster scenarios, WISeSAT ensures financial transaction capabilities remain operational, even when terrestrial infrastructure is compromised.

SEALCOIN transactions processed through WISeSAT benefit from WISeKey’s advanced cybersecurity technologies, including post-quantum cryptographic which ensures protection against emerging cyber threats. This integration not only enhances transaction security but also promotes decentralization, resilience, and global accessibility in the financial ecosystem.

Carlos Moreira, Founder and CEO of WISeKey, noted, “Our integration of SEALCOIN with WISeSAT demonstrates WISeKey’s commitment to driving innovation in blockchain, cybersecurity, and satellite communications. This synergy addresses critical challenges in secure financial transactions, enabling unprecedented global access to cryptocurrency services.”
