The world’s first publicly available quantum proof-of-work simulator, revealed by BTQ Technologies, demonstrates the quantum advantage of blockchain consensus.
The world’s first publicly available Quantum Proof-of-Work (QPoW) Simulator has been formally released by BTQ Technologies Corp., a multinational quantum technology business dedicated to protecting mission-critical networks. This innovative platform represents a major breakthrough in protecting digital assets from new quantum risks by showcasing a completely quantum-native mining algorithm that can still be verified on conventional hardware. The QPoW Simulator provides a quantum counterpart of the SHA-256 proof-of-work algorithm used in Bitcoin.
The purpose of the QPoW Simulator is to provide the market with a measurable, useful quantum advantage. It substitutes a boson sampling work that can be executed on today’s tiny photonic quantum devices for conventional hashing challenges. Energy-efficient mining that is resistant to quantum attacks is made possible by this novel technique. “Quantum Proof-of-Work demonstrates that quantum hardware can secure, not threaten, the next generation of digital money,” said Olivier Roussy Newton, CEO of BTQ Technologies. He went on to say, “For the first time, the digital-asset ecosystem can interact with a quantum-secure, energy-efficient consensus mechanism, one that aligns with global regulatory momentum and keeps critical infrastructure resilient in the quantum era” .

Key Highlights of the QPoW Simulator:
- Coarse-grained boson sampling in live, real-time mining cycles with quantifiable quantum advantage.
- By adjusting variables like photon count, optical modes, and measurement bins, users can investigate trade-offs between security and performance.
- Utilize interactive analytics to visualize network information, compare miner outputs, and verify submissions using peak-bin-percentage (PBP) and total-variation-distance (TVD) checks.
- energy-efficient approach that relies on the quality of photonic hardware instead of brute-force hashing, separating difficulty from power consumption.
- By switching the work function from hash inversion to provably hard quantum sampling, post-quantum resilience removes weaknesses to Grover-style attacks.
Implications for Digital Assets and Regulatory Alignment:
The growing energy demands of ASIC mining and the potential for quadratic speed-ups due to quantum assaults are two convergent stresses on current proof-of-work systems. These pressures are directly addressed by BTQ’s QPoW Simulator. By altering the photon count and optical modes, network operators can increase or decrease the difficulty, enhancing security against quantum adversaries without using more resources.
The task’s quantum nature ensures that no single quantum device will have a disproportionate advantage in producing blocks over others, even as quantum devices become more proficient at generating valid samples as the boson sampling problem becomes more challenging. Because of this, QPoW Simulator is a workable solution for digital asset networks to preserve security and efficiency in the quantum era.

This invention supports a global regulatory movement that aims to make quantum resilience necessary. On June 23, 2025, the European Commission released its Coordinated Implementation Roadmap for the Transition to Post-Quantum Cryptography, which calls on all EU member states to safeguard vital infrastructure by 2030 and start the PQC migration by 2026. The shift from recommendation to implementation was also marked in the US by NIST’s March 2025 designation of the HQC algorithm as a fifth post-quantum standard. These significant events highlight the vital necessity of consensus layers, such as BTQ’s QPoW Simulator, whose security presumptions hold true in the age of quantum computing.
Earlier this year, at the Bank for International Settlements’ (BIS) Quantum-Readiness for Central Banks and Supervisors meeting, the central bank perspective emphasized the systemic significance of quantum-secure settlement. 39 central banks concurred at this conference that next-generation ledgers need to be resistant to quantum attacks. In line with the BIS mandate, the QPoW’s classically verifiable yet quantum-native design provides a workable approach for wholesale Central Bank Digital Currency (CBDC) pilots and other high-value payment rails to become quantum-ready without having to replace their current node infrastructure.
Ecosystem Momentum and BTQ’s Roadmap:
The Quantum Industrial Standard Association (QuINSA) has accepted the QPoW protocol as its first consensus work item. Additionally, QPoW Simulator is now positioned as a top candidate for future ISO-style standards for quantum-secure blockchain technologies, with BTQ’s appointment as chair of the alliance’s quantum communications working group.
A component of BTQ’s larger strategic plan is the QPoW Simulator. In addition to establishing a strategic alliance with QPerfect to verify QPoW on neutral-atom quantum processors, BTQ launched the Quantum Stablecoin Settlement Network (QSSN) last month, which would expand quantum security to tokenized dollars. These efforts highlight BTQ’s primary goal of accelerating the commercial adoption of quantum-secure banking and other quantum-grade solutions while bringing a useful quantum advantage to market via a full-stack platform.
