Abstract

This research introduces the Decentralized Finance (DeFi) TrustBoost Framework, which combines blockchain technology and Explainable AI to address challenges faced by lenders underwriting small business loan applications from low-wealth households. The framework is designed with a strong emphasis on fulfilling four crucial requirements of blockchain and AI systems: confidentiality, compliance with data protection laws, resistance to adversarial attacks, and compliance with regulatory audits. It presents a technique for tamper-proof auditing of automated AI decisions and a strategy for on-chain (inside-blockchain) and off-chain data storage to facilitate collaboration within and across financial organizations.

Keywords: DeFi, Explainable AI (XAI), Blockchain Auditing, Small Business Lending, DeFi

Complexity vs Empirical Score

• Math Complexity: 2.5/10
• Empirical Rigor: 4.0/10
• Quadrant: Philosophers
• Why: The paper is conceptually focused on a framework integrating blockchain and AI for financial decisions, with minimal advanced mathematical derivations or heavy statistical modeling. While it outlines a system architecture and mentions technical components like hashing and deep neural networks, it lacks detailed implementation specifics, backtest results, code, or datasets typical of high empirical rigor.
