Sealsq plans to release the QS7001 chip before the end of 2025. The company says blockchain platforms like Hedera and WeCan are currently integrating its post-quantum security stack into their core infrastructure.

Sealsq says its chip uses post-quantum cryptographic (PQC) algorithms to ensure long-term data reliability and transaction integrity.

PQC refers to security measures that are secure against attacks from quantum computers. The effectiveness of existing cryptographic measures, such as SHA-256, RSA, and elliptic curve cryptography (ECC), has increasingly been a subject of debate as quantum computers get more powerful each year.

Chinese researchers using D-Wave Systems (QBTS) have already broken RSA encryption, sparking security concerns.

“With the QS7001 Chip, SEALSQ provides blockchain platforms with the tools to transition to post-quantum cryptography seamlessly, defending their users and data against tomorrow’s threats today,” said CEO Carlos Moreira.

Retail sentiment on Stocktwits around Sealsq took a dive despite the company’s announcement, hovering in the ‘bearish’ territory.
