How Do Decentralized Oracle Networks (DONs) Differ from Centralized Oracles in the Context of Financial Derivatives?

A centralized oracle is a single entity providing data, creating a single point of failure. If it is hacked, compromised, or simply makes an error, the financial derivative smart contract it feeds will fail.

A decentralized oracle network (DON) mitigates this risk by sourcing data from numerous independent, geographically dispersed nodes. The DON aggregates this data, often taking a median or average, to arrive at a more reliable and tamper-resistant value.

This decentralization makes it significantly harder and more expensive for any single party to manipulate the data feed for a financial derivative.
