Vancouver-based BTQ Technologies Tests a Quantum Safe Version of Bitcoin
On October 16, 2025, Canadian company BTQ Technologies announced the first public demonstration of a quantum safe Bitcoin network using post quantum cryptography approved by the US National Institute of Standards and Technology. BTQ says its new Bitcoin software replaces current encryption with ML DSA, a stronger digital signature designed to resist future quantum attacks that meets NIST’s new post quantum security standards. The firm believes this advance could protect the $2.4 trillion dollar Bitcoin market from quantum attacks expected later this decade.
Quantum Risk and What's at Stake
Quantum computing promises huge advances, but with it comes the threat to current cryptography, including what bitcoin's network is secured by. Researchers aim for million qubit systems before 2030, a level that could make today’s digital signatures vulnerable. The Federal Reserve study on harvest now decrypt later risks explains how attackers can store blockchain data for future decryption once quantum computers mature. BTQ is raising alarm bells that more than 6.5 million Bitcoin already expose public keys, worth hundreds of billions of dollars, and could be stolen if quantum systems gain that capability.
BTQ and Its Technical Demo
BTQ is pushing quantum security for digital assets. Earlier in 2025 it launched the Quantum Stablecoin Settlement Network (QSSN) to protect stablecoins under quantum threats. The company also leads standard efforts and was recently appointed chair of the QuINSA standards group to help create quantum-safe blockchain policies.
In its demo, BTQ built a version of Bitcoin where every signature uses ML DSA, a NIST-standardized post quantum algorithm. Their prototype supports wallet creation, transaction signing, mining, and verification under the new scheme. To accommodate larger signatures they increased script limits and block structure. The company released details in its Quantum Safe Bitcoin press release.

Despite the excitement experts are cautious as no independent cryptographic audit or open repository has confirmed BTQ’s claims. Changing the signature scheme that secures Bitcoin would require widespread agreement among miners, developers, and exchanges, a process that historically takes years. The firm describes its system as a demonstration, not a replacement. Until peer review validates its performance and compatibility, BTQ’s project is more like a promising proof of concept rather than a verified production network.
What It Means for Fintech and Policy
Quantum readiness is already entering regulatory planning. The National Security Memorandum on quantum computing directs federal agencies to prepare for migration to NIST approved cryptographic standards. If BTQ’s model scales, it could guide how institutions and regulators protect digital assets. For investors this is an early look at how future value may depend on verified quantum resilience.
Outlook
BTQ plans to launch its test network before the end of 2025, followed by enterprise pilots and a main network rollout in 2026. Whether Bitcoin developers adopt these standards is still uncertain, yet the announcement places Canada at the center of the conversation about safeguarding global digital wealth. The rise of quantum safe assets is evolving into a critical piece of tech that will protect and propel the next decade of digital finance.
