Definition. Lightning Network Gini Coefficient (Channel Distribution) is a statistical measure of how channel counts are distributed across nodes on the Lightning Network, used to monitor the degree of centralization and the potential risks associated with highly concentrated node influence.

Technical. The coefficient is computed by comparing the actual distribution of channels across nodes to a hypothetical uniform distribution. It ranges from 0 to 1, with 0 representing perfect equality and 1 representing maximum inequality.

Interpretation. A higher Gini coefficient indicates a more unequal distribution of channel counts across nodes, while a lower coefficient indicates a more even distribution.
