The Lightning Network: High-Velocity Global Settlement on the Bitcoin Base Layer

While Bitcoin's base layer functions as a global settlement ledger with deliberate block confirmation times, the Lightning Network executes peer-to-peer micropayments near the speed of light at negligible cost.

By establishing bidirectional payment channels verified through multi-signature script opcodes, nodes route transactions without congesting the main blockchain. Remittance operators and international merchants increasingly utilize this rail for instantaneous fiat-to-Bitcoin-to-fiat transfers.

Channel capacity growth and improved node management software have bolstered reliability, paving the way for scalable global micro-transactions.
