SEALSQ Launches Quantum-Resistant Chip to Secure Bitcoin Wallets Against Future Quantum Threats
May 21, 2025
Quantum-Si reported a productive quarter with advancements in product development and an expansion of its international channel partner network, despite facing challenges in the U.S. life sciences market.
To aid developers, SEALSQ has established a migration framework that supports hybrid cryptography, allowing for a smooth transition to quantum-safe methods while maintaining compatibility with existing systems.
SEALSQ Corp has unveiled the QS7001 secure element, a post-quantum cryptographic solution specifically designed to protect Bitcoin wallets from the emerging threats posed by quantum computing.
This innovative chip integrates the NIST-standardized CRYSTALS-Kyber and CRYSTALS-Dilithium algorithms, which facilitate secure key exchanges and provide quantum-resistant digital signatures to ensure transaction integrity.
The introduction of this technology is critical as quantum computing advances, potentially compromising the integrity of Bitcoin's $1 trillion market.
Carlos Moreira, CEO of SEALSQ, emphasized the urgent need for post-quantum cryptography to future-proof blockchain security, highlighting the necessity for Bitcoin to evolve alongside quantum computing advancements.
Currently, Bitcoin wallets rely on elliptic curve cryptography (ECC), which is susceptible to quantum attacks, particularly through algorithms like Shor’s that can derive private keys from public keys.
This dual-stack approach enables developers to utilize both traditional ECDSA and new quantum-resistant signatures during the transition, ensuring a seamless upgrade path.
D-Wave Quantum has announced the general availability of its Advantage2 quantum computing system, which is designed to tackle complex problems that exceed the capabilities of classical computing.
At the 'Quantum Days 2025' event in France, SEALSQ showcased live demonstrations of its post-quantum cryptography solutions, reinforcing its commitment to providing quantum-resistant security.
In a related development, Nvidia has launched the Global Research and Development Center for Business by Quantum-AI Technology (G-QuAT), featuring the ABCI-Q supercomputer, the largest dedicated to quantum computing.
Meanwhile, IonQ has partnered with Einride to explore quantum computing applications aimed at optimizing fleet logistics, enhancing efficiency and sustainability in the freight industry.
