SEALSQ Quantum-Resistant Technology Tackles Potential Bitcoin's Quantum Vulnerabilities

Geneva, Switzerland, July 02, 2025 (GLOBE NEWSWIRE) --

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 reaffirmed its commitment to a quantum-secure future by announcing new advancements in post-quantum cryptography (PQC) aimed at mitigating existential threats to Bitcoin and blockchain networks.

Several months ago, SEALSQ raised alarms about the looming risk posed by quantum computing to existing cryptographic frameworks https://thequantuminsider.com/2024/12/24/sealsq-quantum-resistant-technology-tackles-potential-bitcoins-quantum-vulnerabilities/. Through its QUASARS (Quantum Resistant Authentication Security and Robustness for Systems) project, SEALSQ is pioneering hybrid cryptographic solutions and quantum-resistant hardware designed to protect mission-critical infrastructures, such as IoT devices, secure communications, and blockchain protocols, from quantum-powered cyberattacks.

Recent industry analyses, including insights from prominent digital asset commentators such as @AltcoinGordon and IBM Quantum’s Jay Gambetta, the severity of the threat. Quantum computing is rapidly approaching the capability to break the elliptic curve cryptography (ECC) that underpins Bitcoin and Ethereum. According to cybersecurity researchers, over 4 million BTC, approximately 25% of the usable supply, are stored in addresses with exposed public keys, making them prime targets once a cryptographically relevant quantum computer arrives.

BlackRock, the world’s largest asset manager, has formally recognized this risk by listing quantum computing as a material threat in its Bitcoin ETF filings. The threat is not hypothetical: Harvest Now, Decrypt Later attacks are already underway, as nation-states siphon encrypte blockchain data in anticipation of breaking it post-Q-Day.

SEALSQ: Delivering Quantum Resilience Now
SEALSQ is at the forefront of solving this challenge. The Company’s PQC-enabled microcontrollers and secure elements offer drop-in hardware upgrades for existing digital systems. These components are designed to:

• Protect against quantum decryption attacks in real time.
• Enable hybrid cryptographic architectures combining classical and quantum-resistant algorithms.
• Secure the blockchain ledger and wallet infrastructure without requiring prolonged network downtime.
  
  
  

“Our mission is to provide the building blocks for a quantum-secure digital economy,” said Carlos Moreira, CEO of SEALSQ. “The threats are not on the horizon, they are here. SEALSQ's post-quantum innovations are designed to future-proof blockchain ecosystems and uphold the core values of decentralization, privacy, and individual sovereignty.”

SEALSQ’s Commitment to a Quantum-Secure Future
