## Node Centrality

Node centrality is a metric used to determine the relative importance of a participant or protocol within a larger network. In blockchain networks, this can refer to the concentration of mining power, validator stake, or the volume of assets locked in a specific smart contract.

High centrality indicates that a node is a critical hub; if it fails or acts maliciously, the entire network may experience severe disruption or loss of trust. This concept is vital for evaluating the decentralization of a protocol and its resistance to censorship or technical failure.

Analysts use centrality measures to identify potential points of control where regulators or attackers might exert undue influence. Balancing node centrality is a core challenge in protocol design, as it involves a trade-off between network efficiency and distributed resilience.
