Oracles in Decentralized Finance: The Infrastructure of Pricing

Abstract

Blockchain oracles combine, within a single arrangement, activities that traditional finance assigns to distinct and in part regulated entities. We develop a four-stage oracle data lifecycle framework, covering sourcing, collection and reporting, aggregation, and delivery and consumption, and compare each stage with its counterpart in traditional wholesale data markets. In traditional markets, safeguards attach at the regulated start and end points of that lifecycle, and liability for mispricing rests on identifiable contractual parties. In DeFi, no regulated end-point exists: smart contracts execute on oracle prices automatically and irreversibly, and end-users bear mispricing risk without redress. Distinguishing control-based from supply-based regulatory hooks, we classify oracles as suppliers to DeFi arrangements. Because the risks accompanying the same activities differ, transplanting benchmark regulation would be disproportionate. We identify three paths forward: DeFi literacy, public-permissioned oracle networks, and regulated benchmark administrators publishing on-chain.
