Node Diversity
Node Diversity refers to the geographic, institutional, and technical variety of participants running an oracle network. By ensuring that nodes are not concentrated in a single location or controlled by a single entity, the network reduces the risk of coordinated attacks or localized outages.
High diversity means that an adversary must overcome a wide range of hurdles to compromise the consensus, making the system significantly more secure. This is a key requirement for decentralized infrastructure, as it prevents systemic vulnerabilities that arise from homogeneity.
It supports the principle of decentralization by ensuring that the data reporting process is truly distributed and resistant to censorship or manipulation. Maintaining this diversity is an ongoing effort that requires incentivizing a broad base of independent node operators.
