Explain the Concept of a “Sybil Attack” in the Context of Oracle Networks.
A Sybil attack occurs when a single malicious entity creates and operates numerous fake identities (Sybil nodes) within the oracle network. The goal is to gain a disproportionately large influence over the aggregated price feed, allowing the attacker to manipulate the final reported price.
Robust identity verification and high staking requirements are used to defend against this.
