South Korea’s most populous province plans a blockchain-based proof-of-concept for regional currency, public subsidies and payments, with later testing set to expand into privacy, reserve verification and programmable transfers.
Gyeonggi Province in South Korea plans to launch the first phase of a blockchain-based stablecoin proof-of-concept in August 2026 as it explores use cases tied to regional currency, public subsidies and payments. The project, led by blockchain security company ZKrypto and previously cited by NexBlock, will first test issuance, circulation and settlement, then expand between October and December if progress is smooth. The later stage is set to evaluate programmable payments, zero-knowledge proofs and proof of reserves, alongside fraud prevention, privacy safeguards and possible deployment across public benefit programs. The eight-month initiative is scheduled to run through February 2027. The government-backed effort comes as private-sector groups also step up work on won-linked digital payment rails, with Toss signing a strategic agreement with Optimism and Sunnyside Labs for a three-month proof-of-concept on infrastructure for South Korean won-linked stablecoins, and KT outlining broader investment plans that include tokenization services and infrastructure for won-based stablecoins.
