Was ist Lightning Network?
A network of payment channels built on Bitcoin that settles small payments off-chain, using the base layer only to open and close channels.
Two parties lock funds in a channel and then update the balance between them by exchanging signed states. Only the opening and closing transactions touch the chain, so payments are near-instant and cost a fraction of a cent.
Lightning changes the cost and speed of payments. It does not change the supply schedule or the base layer's security model, and it introduces its own considerations: channel liquidity, routing, and the need to be online to defend against an old-state broadcast.
Lightning is not a separate coin and not a sidechain. The bitcoin in a channel is real bitcoin, encumbered by a contract.
