The total amount of BTC locked in the Lightning Network. The Bitcoin Lightning Network is a Layer 2 payment protocol built on top of the Bitcoin blockchain. It is designed to provide faster, cheaper, and more scalable transactions than traditional on-chain Bitcoin transactions.

This is the Point-in-Time (PiT) variant of Lightning Network Capacity. 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.
