Lightning is an open-source payment layer that rides on top of Bitcoin, built to move money at high speed and low cost. Instead of waiting minutes for an on-chain confirmation, Lightning routes payments in seconds, usually for less than a fraction of a cent, while leaning on Bitcoin’s proven security underneath.

Why Lightning?

• Speed: Payments confirm in seconds, perfect for checkout lines and live online experiences.

• Tiny Fees: Typically just a sliver of a cent, so everyday spending stays affordable.

• Security: Every transaction ultimately settles on the Bitcoin blockchain, keeping the same rock-solid protection.

• Micro-Payments: Send amounts as small as one ten-thousandth of a cent, ideal for pay-per-click, streaming payments, or tipping creators.

In short, Lightning turns Bitcoin into a practical, retail-ready payment system—fast, cheap, and reliable for everything from coffee runs to micro-transactions online.
