The Gini coefficient of the Lightning network capacity is a statistical measure of the distribution of Bitcoin capacity among the nodes on the Lightning Network. It is calculated by comparing the actual distribution of Bitcoin capacity among the nodes to a hypothetical uniform distribution. It ranges from 0 to 1, with 0 representing perfect equality and 1 representing maximum inequality. A higher Gini coefficient indicates a more unequal distribution of Bitcoin capacity among nodes, while a lower Gini coefficient indicates a more even distribution of Bitcoin capacity. The Gini coefficient of the Lightning network capacity can be used to monitor the degree of centralization and potential risks associated with a highly concentrated distribution of Bitcoin capacity.

This is the Point-in-Time (PiT) variant of Lightning Network Gini Capacity Distribution. PiT metrics are strictly append-only and their history is immutable. The historic data does not necessarily reflect the best current knowledge, but the information at the time when a data point was first computed. PiT metrics are ideal candidates for applications in model backtesting and related quantitative purposes. Read our article on PiT metrics for more information.
