BTQ Technologies Corp. (NASDAQ:BTQ) saw its stock climb 7% in pre-market trading Thursday after announcing a successful demonstration of a quantum-resistant Bitcoin implementation using National Institute of Standards and Technology (NIST)-standardized post-quantum cryptography.
The company’s Bitcoin Quantum Core Release 0.2 replaces Bitcoin’s ECDSA signatures with the NIST-approved ML-DSA (Module-Lattice Digital Signature Algorithm). BTQ says this upgrade can protect against future quantum computing threats that could compromise Bitcoin’s $2.4 trillion market capitalization.
The demonstration showed a full transaction lifecycle secured with post-quantum cryptography, including wallet creation, transaction signing, verification, and mining. By using FIPS 204 standardized ML-DSA, the implementation delivers 128-bit post-quantum security, effectively replacing vulnerable signature schemes.
“The quantum threat to Bitcoin is an existential risk to the entire $2.4 trillion Bitcoin economy,” said Olivier Roussy Newton, CEO of BTQ Technologies. “Once quantum computers can break ECDSA signatures, every single transaction becomes vulnerable to interception and theft. While the developer community debates response strategies, we’ve built and demonstrated a working, NIST-compliant solution that can protect Bitcoin’s full market value today.”
BTQ also pointed out that around 6.65 million Bitcoin currently have permanently exposed public keys, leaving them open to “long-range attacks” that quantum computers could exploit in the future.
To coordinate broader security efforts, the company announced the launch of the BTQ Foundation, aimed at fostering industry-wide collaboration on quantum defense.
BTQ’s roadmap includes:
- Testnet launch and security auditing in Q4 2025
- Enterprise pilot programs in Q1 2026
- Mainnet launch with migration tools in Q2 2026
- Integration with major exchanges and wallet providers through 2026–2027.
- BTQ Technologies stock price
