Design and Deployment of a Multi-Party Distributed Ledger Technology for Loan Management Using R3 Corda

Abstract

This paper introduces a robust, scalable, and flexible workflow architecture designed to overcome longstanding challenges in the financial services sector. Financial institutions often face operational bottlenecks due to fragmented legacy systems, redundant Know Your Customer (KYC) procedures, and manual, error-prone processes. To address these inefficiencies, we propose a secure, distributed architecture leveraging the Distributed Ledger Technology (DLT) of R3 Corda to ensure immutable, auditable, and tamper-resistant records. The system integrates RESTful APIs to abstract the underlying blockchain complexity, providing seamless interoperability between banking systems and third-party services. Key modules include automated KYC verification, loan processing, and document authentication, which collectively reduce processing times, lower operational risk, and enhance regulatory compliance. To ensure user accessibility, the system features an intuitive graphical user interface (GUI) developed with Bubble.io, creating a seamless and efficient mechanism for end-to-end loan life cycle management. The system's modular architecture is validated through extensive testing, including Cypress-based automation, and is designed for future scalability, positioning it as a forward-thinking solution for broader adoption of blockchain in digital financial services.
