Lightning Network
This section is growing. We only publish what we can source, so it starts lean.
Primary sources
Read the original draft: "The Bitcoin Lightning Network: Scalable Off-Chain Instant Payments" (lightning.network PDF).
Implementations interoperate through the Basis of Lightning Technology specifications (BOLTs on GitHub). Bitcoin Optech keeps a technical topic index (bitcoinops.org).
Coming next
Guides to Lightning wallets and their backup trade-offs are in progress. Until then, learn on-chain self-custody first.
