South Korea Develops Quantum-Safe Stablecoin Infrastructure

South Korea's financial sector is taking steps to mitigate the threat of quantum computing to its digital currency infrastructure. iM Bank has partnered with BTQ Technologies and Finger Inc. to develop a proof-of-concept for a Korean won (KRW) stablecoin that incorporates post-quantum security measures.

The pilot program, which was announced on Wednesday by BTQ Technologies, will use the company's Quantum Secure Stablecoin Settlement Network to enable real-time reconciliation between bank reserves and on-chain supply. This is a critical aspect of digital currency infrastructure, as it ensures that the amount of digital currency in circulation accurately reflects the underlying assets.

The project also aims to test a standardized smart contract design and connectivity for overseas distribution. BTQ Technologies will provide strategic advisory support throughout the partnership with iM Bank and Finger Inc.

By embedding post-quantum cryptography into its stablecoin, iM Bank can maintain operational continuity while preparing for future quantum threats. This is particularly important as eight Korean banks advance plans to issue a joint KRW stablecoin, signaling a competitive build-out of regulated digital won infrastructure ahead of expected legislation.
