BTQ Technologies has stepped into a pivotal role in South Korea’s evolving digital finance landscape, becoming the core post-quantum cryptography (PQC) provider for a new bank-led stablecoin initiative. The company is working alongside Finger Inc. and iM Bank in a proof-of-concept designed to test a Korean won stablecoin secured against future quantum computing threats.

Far from a routine pilot, the initiative reflects growing urgency among financial institutions to prepare for the next era of cybersecurity. BTQ is not only deploying its Quantum Secure Stablecoin Settlement Network (QSSN) but also coordinating strategy and implementation across the three partners.
Building a quantum-resilient payment framework
At the heart of the project is a system designed to ensure stability, transparency, and future-proof security. The pilot will test real-time reconciliation between bank reserves and blockchain-issued tokens while integrating a dual-signature structure that combines traditional cryptography with PQC standards.
This hybrid approach allows institutions to maintain current operations while gradually transitioning to quantum-resistant systems. It also addresses rising concerns about “harvest-now, decrypt-later” attacks, in which encrypted data could be compromised as quantum computing advances.
The infrastructure will run on the Kaia mainnet, a Layer 1 blockchain formed by the merger of the Klaytn and Finschia networks, both tied to major tech ecosystems in Asia. This positions the project within a broader regional push toward scalable and regulated digital asset systems.
From concept to commercial momentum
BTQ’s QSSN framework plays a central role by securing critical stablecoin functions such as issuance, transfers, and administrative controls without disrupting user experience. The company has aligned its technology with emerging global standards, including those developed by the U.S. National Institute of Standards and Technology.
Meanwhile, South Korea’s Ministry of Finance and Economy is preparing to launch a pilot program that will test the use of blockchain-based deposit tokens for official government expenses, marking a step toward modernizing public sector payments.
