SEALSQ Launches Quantum-Resistant Crypto Chip QS7001 to Secure Bitcoin Wallets
SEALSQ Corp. has deployed their QS7001 secure element, which uses post-quantum cryptography (PQC) technology, to protect Bitcoin wallets against future quantum computers. This upgrade improves blockchain security and fixes a major Bitcoin architecture flaw.
Modern Bitcoin wallets generate public-private key pairs and protect transactions using elliptic curve cryptography (ECC), notably the secp256k1 curve. Even without classical assaults, Shor's technique may allow quantum computers to derive secret keys from exposed public keys. Address reuse and broadcast transactions threaten decentralised banking as quantum computing advances.
SEALSQ prevents this vulnerability by embedding a hardware-based PQC solution into the QS7001 secure element. A sophisticated device called the QS7001 protects cryptographic keys and operations. The system uses NIST-standardized quantum-resistant algorithms CRYSTALS-Kyber for key encapsulation and CRYSTALS-Dilithium for digital signatures. Lattice-based algorithms provide forward secrecy and unforgeable signatures to protect against Shor and Grover. The implementation of these strategies lends credibility to the solution.
QS7001 secure element hardware supports quantum-resistant signature, key exchange, and post-quantum private key storage. The chip is tamper-resistant, low-power, and developed for hardware wallets and Internet of Things devices. Software-only solutions may be weaker, whereas SEALSQ emphasises hardware-rooted trust. The protection is strengthened by WISeKey's Quantum RootKey architecture.
SEALSQ provides a migration architecture for blockchain developers and custodians that addresses real-world challenges of migrating cryptographic standards. The purpose of this incremental technique is to minimise infrastructure disruption. The architecture allows hybrid cryptography, combining the post-quantum Dilithium method with the Elliptic Curve Digital Signature method. This allows older system compatibility and gradual deployment. Key rotation allows the secure transition of traditional keys to PQC-protected keys, and quantum-safe addresses unambiguously identify transactions using post-quantum cryptography, ensuring future-proof security.
SEALSQ CEO Carlos Moreira said the company is “ahead of the curve” but quantum computing threatens blockchain security. Without post-quantum cryptography and trusted roots, no blockchain is future-proof. He believes WISeKey's Quantum RootKey architecture and SEALSQ's post-quantum secure microcontrollers can safeguard Bitcoin from quantum threats in a hardware-enforceable fashion. SEALSQ is working with developers and others to enhance PQC standards to create a blockchain post-quantum security ecosystem.
As quantum computing advances, bitcoin custodians, hardware wallet makers, and institutional investors may demand quantum-resistant security, which might have major market effects. SEALSQ may get an early advantage by leading this transformation.
The QS7001 launch is a big step, but existing Bitcoin wallets are vulnerable until the switch to PQC happens, the transition requires major infrastructure changes, and forward-looking statements suggest uncertainty. The rapid growth of quantum computing may need continual technological improvements.
SEALSQ Corp develops and sells semiconductor, PKI, and post-quantum hardware and software. They are developing Post-Quantum Semiconductors to protect sensitive data in other applications like Multi-Factor Authentication tokens, Smart Energy, Medical and Healthcare Systems, Defence, IT Network Infrastructure, Automotive, and Industrial Automation and Control Systems.
