. 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 encrypted blockchain data in anticipation of breaking it post-Q-Day.
