Empowering the Gaming Frontier: Microtransactions with Lightning Network
summary
Prototype integrates Bitcoin Lightning microtransactions into Unity using BTC Pay Server, LND, LNURL and gRPC with Dockerized nodes; invoices and withdrawals appear as QR codes scanned by a phone and confirm near‑instantly. LND provides automatic channel management and pathfinding, backend funds initial channels (company covers bootstrap liquidity), and LNURL can authenticate users. Built demo shows in‑game QR payment flow working, SDK still in development, main tradeoffs are channel funding, node maintenance and a fiddly phone‑scan UX.
