BTQ and Danal Pioneer Quantum-Secure Payment Settlement—National-Scale PoC Goes Live
Largest Quantum-Ready Stablecoin Settlement Pilot Debuts in South Korea
BTQ Technologies has announced the launch of a large-scale proof-of-concept (PoC) of its Quantum-Secure Stablecoin Settlement Network (QSSN) with Danal, Korea’s leading mobile payment operator and the force behind Paycoin (PCI). This is the world’s first major trial to introduce quantum-resistant security and programmable compliance features to an established payment network that already reaches tens of millions of users.
Key Pilot Features: Quantum Security and Real-Time Compliance—With No Change for End Users
The trial aims to assess QSSN’s ability to deliver post-quantum security and programmable issuer controls, such as real-time compliance, velocity limits, and blacklist/whitelist support—all without altering the experience for consumers or merchants. By leveraging Danal’s wide digital footprint, this PoC will run across live payment rails spanning e-commerce, gaming, digital content, and retail. The table below summarizes the scope and technology being tested:
| Feature | Description |
|---|---|
| Quantum-Secure Settlement | Utilizes post-quantum cryptography for protection against emerging quantum computing threats |
| Issuer Controls | Programmable functions like mint/burn, velocity limits, blacklist/whitelist integration |
| Real-Time Compliance | Built-in regulatory hooks to support automated and rapid compliance processes |
| Preserved User Experience | No change for consumers or merchants—QSSN integrates behind the scenes |
Danal’s Market Reach Positions QSSN for Broad Adoption
Danal is a household name in Korea, leading the mobile carrier billing segment since its founding in 1997 and operating the widely-used Paycoin service. Its payment platform connects with telecom partners, online merchants, and retail outlets, serving a customer base of tens of millions. This makes Danal an ideal testbed for technology designed for seamless, national-scale deployment—demonstrating not only technical viability, but real-world scalability.
| Danal Snapshot | Details |
|---|---|
| Founded | 1997 (KOSDAQ: 064260) |
| Coverage | Tens of millions of users via telecom partnerships and e-commerce, gaming, content, retail |
| Notable Product | Paycoin (PCI) – among Korea’s first and most widely adopted crypto payment solutions |
| International Footprint | Subsidiaries and partners in US, China, and other regions |
Compliance and Security Standards Lead the Rollout—PoC Aligns with Global Initiatives
Global regulators are actively moving toward post-quantum cryptography to mitigate so-called "harvest-now, decrypt-later" risk. BTQ’s QSSN addresses this urgency and has already been referenced in international standardization efforts (including QUINSA and U.S. PQFIF), showing it can deliver regulatory compliance at scale—without disrupting operations for end users or payment processors. The deployment enables banks, regulators, and technology partners to gain confidence in large-scale, quantum-secure digital money systems.
A Step Toward Quantum-Resilient Finance
BTQ’s pilot with Danal is more than a tech trial—it’s a statement that large-scale financial networks can be secured against future quantum threats without sacrificing usability. By embedding advanced cryptography and compliance controls into a proven payment ecosystem, the companies demonstrate how quantum-resilient solutions can integrate seamlessly into real-world workflows. For anyone watching the intersection of fintech, compliance, and cybersecurity, this PoC offers a glimpse into what secure digital payments might look like in the near future.
