Node Decentralization Index

The Node Decentralization Index is a mathematical framework used to evaluate the geographic and structural distribution of validators within a blockchain network. It measures how resistant the network is to censorship, localized outages, or coordinated attacks by malicious actors.

A high index indicates that nodes are distributed across diverse jurisdictions, hardware environments, and network providers, reducing the risk of a single point of failure. This metric is critical for assessing the protocol physics of consensus mechanisms, particularly in proof-of-stake systems where stake concentration can undermine security.

Financial derivatives and institutional products often rely on this index to price the systemic risk associated with a specific underlying asset. It acts as a barometer for the network's resilience against regulatory and technical interference.
