World’s First Large-Scale Trial of Quantum-Secure Stablecoin Settlement Network
Danal, Korea’s #1 mobile carrier billing provider and operator of Paycoin (PCI), has begun a Proof-of-Concept of BTQ’s Quantum-Secure Stablecoin Settlement Network (QSSN) across select payment rails, the world’s first large-scale trial of quantum-secure settlement on real infrastructure.
What’s being tested: QSSN adds post-quantum security, programmable issuer controls (mint/burn, velocity limits, lists), and real-time compliance hooks while preserving today’s consumer and merchant UX, leveraging Danal’s reach to tens of millions of users across e-commerce, gaming, digital content, and offline retail.
Why now (reg + standards): The PoC addresses “harvest-now, decrypt-later” risk and aligns with global standardization efforts (e.g., QUINSA, U.S. PQFIF), demonstrating that PQC can be deployed at national scale with carrier-grade performance and without operational disruption.
VANCOUVER, BC, Sept. 29, 2025 /PRNewswire/ – BTQ Technologies Corp. (“BTQ” or the “Company”) (Nasdaq: BTQ) (CBOE CA: BTQ) (FSE: NG3), a global quantum technology company focused on securing mission-critical networks that Danal Co., Ltd. (“Danal“), Korea’s market leader in mobile carrier billing and operator of the Paycoin (PCI) payment service, has begun a Proof-of-Concept (“PoC”) deployment of BTQ’s Quantum Secure Stablecoin Settlement Network (“QSSN”) across select components of its payment infrastructure.
The PoC will evaluate how QSSN can add quantum-secure settlement, programmable issuer controls, and real-time compliance features to Danal’s existing rails while maintaining today’s user experience for consumers and merchants.

Regulation, PQC Readiness, and Standards Alignment
Regulators and market infrastructures are moving to post-quantum cryptography to mitigate “harvest-now, decrypt-later” risk, creating clear urgency for quantum secure settlement. QSSN is leading global standardization efforts for quantum-secure digital money, including initiatives advanced through QUINSA, and has been highlighted by the U.S. PQFIF for its regulator-friendly architecture. By adding cryptographically enforced issuer controls and compliance-ready integrations while preserving existing user and merchant workflows, this PoC demonstrates that PQC can be deployed at national scale with carrier-grade performance and without operational disruption.
“Danal’s reach and track record make it the ideal environment to validate QSSN at real-world scale,” said Olivier Roussy Newton, CEO of BTQ. “This PoC is about delivering quantum-secure settlement and modern issuer controls without changing what users do at checkout. It is a major step toward bringing global standardization and post-quantum readiness to everyday payments.”
“Our priority is to enhance trust, efficiency, and compliance across our payment network while keeping the experience simple for users and merchants,” said a Danal Official. “QSSN’s design fits that mandate: add security and control where it counts, keep everything else familiar.”
