Quick Breakdown:
- BTQ and Danal begin a proof-of-concept for a quantum-secure stablecoin settlement network.
- QSSN adds post-quantum cryptography, issuer controls, and compliance features without altering user experience.
- Trial aligns with global PQC standards as regulators push for quantum-ready financial systems.
Vancouver-based BTQ Technologies has partnered with Korea’s leading mobile payments provider Danal to pilot the world’s first large-scale quantum-secure stablecoin settlement network (QSSN). The proof-of-concept (PoC) will test post-quantum cryptography and compliance-ready features across select Danal payment rails, including its Paycoin (PCI) crypto payment service.

Quantum security meets real-world payments
The QSSN pilot introduces post-quantum cryptography to guard against “harvest-now, decrypt-later” threats while preserving the user experience for merchants and consumers. The network supports programmable issuer controls—such as mint/burn permissions, velocity limits, and blacklist or whitelist rules—and integrates real-time compliance hooks. By leveraging Danal’s vast infrastructure, which reaches tens of millions of users across e-commerce, gaming, and offline retail, the trial aims to show that national-scale quantum security can be deployed without disrupting everyday transactions.
Aligning with global standards
The initiative arrives as regulators worldwide push for post-quantum security standards. QSSN’s architecture aligns with ongoing efforts from organizations such as QUINSA and the U.S. PQFIF, offering a carrier-grade framework for stablecoins and tokenized deposits. Danal, a KOSDAQ-listed company with long-standing ties to Korean telecom operators and banks, provides an ideal testing ground thanks to its established Paycoin service and broad merchant network.
BTQ CEO Olivier Roussy Newton said the trial demonstrates how quantum-secure settlement can be integrated seamlessly into existing payment systems. Danal executives added that the project strengthens trust and compliance while keeping the consumer checkout process unchanged.
The PoC marks a significant step toward merging next-generation cryptography with mainstream digital payments, positioning Korea as a frontrunner in quantum-secure blockchain adoption.
In a related development, Canadian fintech Paytrie has joined the Circle Payments Network (CPN) to expand stablecoin payment capabilities and accelerate the adoption of regulated digital assets like USDC, further underscoring the rapid evolution of secure, compliant crypto payments worldwide. The initiative aims to reduce transaction costs, increase settlement speed, and enhance transparency while operating within a regulated framework.
