The key concept: Lightning works by opening a private "payment channel" between two parties, and transactions happen off-chain until one of them wants to settle to Bitcoin proper. Think of it like running a tab at a bar all night and settling up at the end. π§ Inbound Liquidity What it is: The amount of Bitcoin that other people have available to send TO YOU through your Lightning channel β your capacity to receive payments. Think of it like: The number of lanes on the highway leading INTO your city. If there are no lanes, no one can get in β even if they want to. Why it matters: If you have ZERO inbound liquidity, you literally cannot receive any Lightning payments. Period. For anyone running a merchant node, a creator tip page, or any "Zappable" content, this is the FIRST thing that needs to be set up. Watch out for: β οΈ New Lightning nodes start with ZERO inbound liquidity. You have to actively acquire it β either by spending Bitcoin first (which flips liquidity to your side) or by leasing a channel from a service provider.
