A smart electricity meter charges you by the hour: $0.03/kWh. Using a bank wire to pay $0.36 for 12 hours of electricity would cost more in fees than the electricity itself. Why does Lightning enable this 'machine-to-machine' payment future?

Lightning's fee structure (~0.001% of transaction value) makes paying for electricity by the hour viable. A device could autonomously negotiate and pay for resources without human intervention. This unlocks IoT and programmable money ecosystems.

Machine‑to‑machine payments are…
