BitcoinWorld GIWA Chain Partnership: Dunamu, Hana Financial, and POSCO International Build Blockchain Remittance System to Replace SWIFT In a landmark move for blockchain adoption in traditional finance, Dunamu has signed a memorandum of understanding (MOU) with Hana Financial Group and POSCO International to build a real-time overseas remittance service on the GIWA Chain . This partnership aims to replace the decades-old SWIFT network with a faster, more efficient blockchain-based system. GIWA Chain: The Layer 2 Blockchain for Global Finance The core of this agreement revolves around Dunamu’s Layer 2 blockchain , GIWA Chain . The three companies will connect this blockchain with Hana Financial Group’s extensive foreign exchange network and POSCO International’s global supply chain. This integration allows for real-world fund flows to be processed on-chain, bypassing traditional intermediaries. Dunamu, the operator of South Korea’s largest cryptocurrency exchange, Upbit, designed GIWA Chain specifically for high-volume, low-cost transactions. The blockchain uses an Ethereum-compatible architecture, making it easy for existing financial systems to adopt. By leveraging this technology, the partnership seeks to reduce remittance times from days to seconds. Replacing the SWIFT Network with Blockchain Technology The three companies plan to continue technical verification for transitioning from the existing Society for Worldwide Interbank Financial Telecommunication (SWIFT) network to the GIWA Chain blockchain. SWIFT, established in 1973, processes over 40 million messages daily but suffers from slow settlement times and high fees, especially for cross-border payments. Blockchain technology offers a transparent, immutable, and near-instantaneous alternative. The GIWA Chain initiative targets a specific pain point: international remittances. According to the World Bank, global remittance flows reached over $800 billion in 2023, with average fees exceeding 6%. Blockchain-based systems can reduce these fees to under 1%. Technical Verification and Pilot Testing The MOU outlines a phased approach. First, the partners will conduct technical verification of GIWA Chain’s ability to handle real-time gross settlement (RTGS) requirements. This involves stress-testing the network for high throughput, security, and compliance with South Korean financial regulations. Second, a pilot service for overseas remittances will launch, initially targeting POSCO International’s supply chain partners. POSCO International, a global trading and energy company, processes thousands of cross-border payments monthly. Using GIWA Chain, these payments can be settled in stablecoins or central bank digital currencies (CBDCs) pegged to the Korean won. Hana Financial Group’s Role in Digital Finance Hana Financial Group brings its extensive foreign exchange network to the table. As one of South Korea’s largest financial holding companies, Hana operates branches in over 20 countries. Its expertise in currency conversion and regulatory compliance is critical for the project’s success. The partnership also aims to establish financial infrastructure for efficient global fund management and payment settlements. This includes developing smart contracts that automate currency hedging and settlement, reducing operational risks for businesses. Real-World Applications: From Supply Chains to Remittances The GIWA Chain initiative has immediate practical applications. For example, POSCO International’s supply chain involves multiple currencies and jurisdictions. By using GIWA Chain, the company can settle invoices in real-time, improving cash flow and reducing reliance on costly bank intermediaries. For individual remittances, the service could benefit millions of overseas Korean workers. According to the Bank of Korea, outward remittances from South Korea exceeded $20 billion in 2023. A blockchain-based system could save these workers hundreds of millions in fees annually. Comparison: SWIFT vs. GIWA Chain Feature SWIFT Network GIWA Chain (Blockchain) Settlement Time 1-3 business days Seconds to minutes Transaction Fee 3-7% of amount Transparency Limited (bank-controlled) Full (public ledger) Accessibility Banks only Any entity with internet Operating Hours Business days only 24/7/365 Expert Perspectives on Blockchain Remittance Financial technology analysts view this partnership as a significant step toward mainstream blockchain adoption. Dr. Kim Soo-hyun, a professor of fintech at Seoul National University, notes that “the involvement of a major financial group and a global trading company validates blockchain’s utility beyond cryptocurrency speculation.” However, challenges remain. Regulatory hurdles, particularly around anti-money laundering (AML) and know-your-customer (KYC) compliance, require careful navigation. The partners plan to work closely with South Korea’s Financial Services Commission (FSC) to ensure the service meets all legal requirements. Timeline and Future Outlook The MOU covers an initial 12-month period for technical verification and pilot testing. If successful, a full commercial launch could follow in 2026. The partners have not disclosed the exact investment amount, but industry estimates suggest the project will require significant capital for blockchain infrastructure and regulatory compliance. This development aligns with global trends. Central banks worldwide, including the Bank of Korea, are exploring CBDCs for cross-border payments. The GIWA Chain could serve as a bridge between traditional finance and digital assets, potentially integrating with future CBDC systems. Conclusion The partnership between Dunamu , Hana Financial, and POSCO International to build a remittance service on the GIWA Chain represents a pivotal moment for blockchain in finance. By targeting the inefficient SWIFT network, this initiative promises faster, cheaper, and more transparent international payments. As technical verification progresses, the success of this project could pave the way for widespread blockchain adoption in global finance. FAQs Q1: What is GIWA Chain?
