Trust, Governance, and Risk in Financial Intermediation - A Comparative Analysis of Decentralized and Centralized Finance

Abstract

Decentralized finance has disrupted the lending process by transferring the intermediary role from institutionally-led balance sheets into a public ledger framework of smart contracts, pooled liquidity, and tokenized governance. The relevance of such a change in the lending paradigm is more of a question of different trust mechanisms, where the solvency of actors can be maintained through the imposition of collateral and automated processing [1][3]. A qualitative comparison is made below through a literature-constrained synthesis of five sources on DeFi architecture, flash loan exploits, lending protocol structure, decentralized governance flaws, and extractable value [1]-[5]. The two protocols of Aave and Compound have been selected for being representative DeFi lending cases, as per the allowed literature that points them out to be the top loanable funds protocols, having liquidity pools and variable rates [1][3]. This comparison is made against CeFi as an institution-driven reference point rather than other DeFi lending protocols owing to the asymmetry of the evidence base. Three conclusions are drawn.Second, the risk architecture of DeFi lending is structurally different from other financial institutions in that flash loans, dependence on oracle feeds, smart contract weakness, composable nature, extractable value, and governance capture are not mere flaws in DeFi but inherent aspects of open and highly coupled financial systems [2][4][5]. Third, governance in DeFi is an additional security mechanism, as the governance of protocol control, parameters and responses to emergencies rests on the robustness of token-based decision-making mechanisms [4].
