Insights

Cybersecurity Expert

SEALSQ's new post-quantum cryptography product protects Bitcoin from quantum computing threats, positioning them at cybersecurity's cutting edge.

SEALSQ's launch of the QS7001 secure element represents a significant technological breakthrough in blockchain security. The company is addressing a critical vulnerability in Bitcoin's infrastructure—the susceptibility of elliptic curve cryptography to quantum computing attacks. This isn't theoretical; as quantum computing advances, Bitcoin's $1+ trillion market could become increasingly vulnerable.

The implementation of CRYSTALS-Kyber and CRYSTALS-Dilithium algorithms is particularly noteworthy. These aren't experimental cryptographic protocols but NIST-standardized algorithms (FIPS 203 and ML-DSA), giving SEALSQ's solution substantial credibility. The QS7001's hardware-based approach provides superior security compared to software-only solutions, as quantum-resistant private keys are stored in tamper-resistant silicon.

What's strategically intelligent is their hybrid implementation approach. Rather than forcing an immediate transition that might disrupt the ecosystem, SEALSQ enables a dual-stack approach supporting both traditional ECDSA and new quantum-resistant signatures. This creates a practical migration path for the vast Bitcoin infrastructure—a critical factor for adoption.

The market implications are substantial. As quantum computing advances accelerate, cryptocurrency custodians, hardware wallet manufacturers, and institutional investors will face growing pressure to implement quantum-resistant security. SEALSQ is positioning itself at the forefront of this inevitable transition, potentially creating a first-mover advantage in securing the approximately $900 billion Bitcoin market from what could otherwise be an existential threat.

SEALSQ Unveils Quantum-Resistant Cryptography with QS7001 to Secure Bitcoin Wallets Against Quantum Threat

SEALSQ Corp (NASDAQ: LAES) ("SEALSQ" or "Company"), a company that focuses on developing and selling Semiconductors, PKI, and Post-Quantum technology hardware and software products, today announced the deployment of its advanced post-quantum cryptographic (PQC) technology to protect Bitcoin wallets from future quantum computer attacks. Integrated into the cutting-edge QS7001 secure element, this solution marks a significant step in ensuring the long-term security of blockchain assets in a quantum era.

The Quantum Risk to Bitcoin Wallets
Bitcoin wallets rely on elliptic curve cryptography (ECC), specifically the secp256k1 curve, to generate public-private key pairs. While secure against classical attacks, quantum computers using Shor’s algorithm could potentially derive private keys from exposed public keys, compromising wallets when addresses are reused or transactions are broadcasted. This vulnerability threatens the integrity of decentralized finance as quantum computing advances.

SEALSQ’s Quantum-Resistant Solution
SEALSQ addresses the threat with a robust PQC stack based on CRYSTALS-Kyber and CRYSTALS-Dilithium, NIST-standardized algorithms (FIPS 203 and ML-DSA) designed to withstand quantum attacks. These lattice-based algorithms ensure security against Shor’s and Grover’s algorithms, offering forward secrecy and unforgeable signatures.

Key Features:

• CRYSTALS-Kyber (Key Encapsulation Mechanism): Enables quantum-secure key exchanges between wallets and blockchain nodes, replacing vulnerable ECC-based protocols.
• CRYSTALS-Dilithium (Digital Signature Algorithm): Provides quantum-resistant digital signatures, ensuring transaction authenticity and integrity.

QS7001 Secure Element: Hardware-Backed Security
SEALSQ’s PQC algorithms are embedded in the QS7001 secure element, a tamper-resistant chip optimized for resource-constrained environments like hardware wallets and IoT devices. The QS7001 enables:

• Secure storage of post-quantum private keys.
• Efficient quantum-resistant signing and key exchange operations.
• Hardware-rooted trust with low power consumption, ideal for cold wallets and embedded systems.
  
  

Migration Framework for Blockchain Developers
SEALSQ offers a practical migration path for Bitcoin wallet developers and custodians:

• Hybrid Cryptography: Supports a dual-stack approach (ECDSA + Dilithium) for backward compatibility during the transition to PQC.
• Quantum-Safe Addresses: Introduces a new address format for quantum-resistant wallets, ensuring future-proof security.
• Key Rotation Tools: Facilitates secure migration of legacy keys to PQC-protected keys, minimizing exposure risks.
  
  

Strategic Vision
“Quantum computing poses a real threat to blockchain security, but SEALSQ is ahead of the curve,” said Carlos Moreira, CEO of SEALSQ. “Our QS7001 secure element, optimized for running both traditional and NIST-standardized PQC algorithms, empowers the blockchain ecosystem to stay secure in a post-quantum world, reinforcing SEALSQ’s leadership in semiconductor-driven cybersecurity.”

Mr. Moreira added, “Without trusted roots, no cryptography can be truly secure. Without post-quantum cryptography, no blockchain can be future-proof. The convergence of SEALSQ’s post-quantum secure microcontrollers and WISeKey’s Quantum RootKey infrastructure provides the only practical, scalable, and hardware-enforceable solution to defend Bitcoin from quantum threats. As the world transitions from classical to quantum computing, Bitcoin must evolve too. This evolution begins at the cryptographic root—trust anchored in post-quantum resilience. If Bitcoin is to remain a trusted store of value in the quantum era, its future may very well depend on what SEALSQ and WISeKey are building today.”
