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 a national scale with carrier-grade performance and without operational disruption.
BTQ Technologies Corp., a global quantum technology company focused on securing mission-critical networks that Danal Co., Ltd., 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.
