In What Ways Do Oracle Services Introduce New Intermediary Risks in Decentralized Finance?

Oracles, while essential for connecting smart contracts to real-world data, reintroduce a form of centralized trust in a decentralized system. This creates a single point of failure; if an oracle is compromised, hacked, or simply provides incorrect data, it can trigger incorrect smart contract executions, leading to significant financial losses.

This dependency means users are not just trusting the blockchain's code, but also the reliability and security of the off-chain oracle provider. This reintroduces counterparty risk, the very problem disintermediation aims to solve.
