According to Newsis, BNK Busan Bank and the K-STAR consortium have completed a proof of concept for a blockchain-powered digital won on the Kaia blockchain mainnet, achieving a 100% transaction success rate and sub-one-second settlement processing.
The consortium comprised BNK Busan Bank, AhnLab Blockchain Company, OpenAsset, Kaia, and Lambda256. The pilot covered the full payment cycle from currency issuance and wallet loading to customer payments and merchant settlements, with the system enabling policy-based controls such as spending restrictions to approved merchants and automatic expiration of unused balances.
