On April 16, 2025, the 2025 AWS Global Expansion Conference was in full swing, with the financial industry forum drawing the attention of numerous professionals in the field. Mr. Limin Zeng, General Manager of the Innovation Division at K-Tech, shared insights on blockchain applications in global supply chain finance, offering new ideas and directions for industry development.
K-Tech is backed by KASIKORNBANK, a bank with a history dating back to 1945. Over its 80-year journey, KASIKORNBANK has grown to employ nearly 19,000 staff members, with a group size exceeding 30,000 people. Its national-level wallet application, K Plus, boasts 23 million active users in Thailand, demonstrating significant influence. As the first fintech company established by a foreign bank to receive regulatory approval, K-Tech has made in-depth deployments in blockchain solutions, supply chain finance, risk control, mobile banking, and digital banking.
Mr. Limin Zeng highlighted that the global supply chain finance market has reached a scale of 1.3 trillion US dollars, with a compound annual growth rate of over 17% in the past five years. China is the largest and fastest-growing market in this sector. However, current supply chain finance faces challenges such as single financing channels, difficult approval and disbursement, high financing costs, information asymmetry, poor traceability, and delayed cross-border payments.
To address these challenges, K-Tech has proposed innovative solutions. In terms of technology integration, it combines regulatory-compliant blockchain technology with privacy protection and Layer 2 expansion. For example, its self-developed public chain emphasizes compliance, stabilizes transaction costs through a dual-token mechanism, builds in a global KYC scenario to ensure compliant operations, allows developers and operators to subsidize gas fees, grants regulatory chains veto power for upgrades, establishes a blacklist mechanism, and uses AI and manual auditing to ensure the security of smart contracts and DApps.
In the privacy protection plan, zero-knowledge proof technology is used to hide transaction information while meeting regulatory needs through a viewing key mechanism. This plan can be applied to scenarios such as privacy in accounts receivable financing, anonymous fund extraction by suppliers, and tiered financing for multi-level suppliers. It also explores compliant privacy payments that unify payment and information flows in countries and regions where regulations permit.
In Layer 2 integration, transaction packaging reduces costs and enhances performance, supporting the connection of information from IoT devices and other related systems. Moreover, K-Tech fully recognizes the convenience that cloud infrastructure brings to system development and deployment operations. AWS is a key cloud platform partner. By leveraging AWS, K-Tech utilizes its trusted execution environment, application group auto-scaling, and comprehensive key management supporting various elliptic curves to help quickly implement supply chain finance and blockchain scenarios.
K-Tech not only continuously innovates in technology but also actively promotes Chinese solution providers to expand into overseas markets. In the future, K-Tech will continue to focus on supply chain finance and blockchain, strengthen cooperation, inject new vitality into industry development, and look forward to working with more partners to create a new future for fintech.
