How Does a DON Mitigate the Risk of a Sybil Attack?

A Sybil attack is where a single malicious actor operates multiple oracle nodes to corrupt the data feed. DONs mitigate this through economic incentives and penalties, primarily staking.

Nodes are required to stake collateral, which is slashed if they provide incorrect or malicious data. Additionally, node operators must undergo reputation and identity verification processes to ensure a diverse and credible network.
