Integration of Blockchain or Distributed Ledger Technologies for Secure, Transparent Onboarding and Lending Workflows

In today’s financial landscape, customer onboarding and lending workflows are increasingly scrutinized for inefficiencies, security vulnerabilities, and compliance risks. Traditional processes rely heavily on centralized databases, manual verifications, and redundant Know Your Customer (KYC) checks, all of which contribute to high operational costs, delays, and susceptibility to fraud. As financial institutions seek more resilient and transparent systems, the integration of blockchain and distributed ledger technologies (DLT) emerges as a promising solution.
This paper explores how blockchain—particularly permissioned or consortium-based architectures—can transform onboarding and lending processes by introducing secure, tamper-proof, and auditable transaction records. We present a conceptual framework that leverages smart contracts, decentralized identity (DID), and verifiable credentials (VC) to automate and streamline key steps in customer verification, loan approval, and regulatory reporting. By enabling shared, real-time access to validated information among trusted parties, DLT can reduce duplication, enhance trust, and improve compliance with regulatory mandates such as AML/KYC and data protection laws.
The study also evaluates practical considerations, including system interoperability, privacy challenges, governance models, and legal implications. Case examples and pilot initiatives are reviewed to ground the theoretical model in real-world implementations. Ultimately, this paper aims to provide a comprehensive foundation for understanding and applying blockchain-based systems in the financial sector’s most sensitive workflows.
