Daily Observation of Cryptography Technology: Toss Partners with the Korea Minting and Security Printing Corporation to Validate OP Stack, Local Gift Vouchers Move Towards a New Era of "Instant Settlement for Single Transactions"
Released on September 22, 2026. The Ethereum Layer 2 scaling solution has undergone a significant experiment in national-level public payment scenarios. Toss, the operator of a South Korean fintech super app, and KOMSCO, the official minting and printing company of South Korea, jointly announced that they have successfully completed a proof of concept (PoC) for blockchain payment of the "Local Love Voucher" on the OP Stack, a modular architecture under Optimism. By compressing the recharge, consumption, and final merchant settlement into a single on-chain transaction, it has completely broken the traditional financial interbank settlement barriers that last for several days, setting a benchmark for low-cost and high-efficiency blockchain implementation in the digital transformation of public finance.
