The ( @Plasma ) PlasmaBFT sub-second settlement close doesn't care if you're ready.
Lagos shop. QR taped to glass, peeling. Customer scans, USDT flashes, that soft beep. Gasless. Actually zero. The Plasma's paymaster ate the fee before she looked up.
She's used to lag. Old POS, Tron congestion, Ethereum's "are you sure" screen. Plasma looks familiar... EVM wallet, same buttons, but the physics are wrong. Bitcoin-anchored finality. Sub-second. No pending. No speed-up.
First scan didn't vibrate. Muscle memory: hit again when uncertain. So she did.
Both landed. Same timestamp. Plasma One shows them like duplicates are normal. Reth execution, Fast HotStuff consensus, already stamped. Irreversible.
Printer kept going. That's how they knew.
Manager leans over. "Which one do I refund?"
She stares. Holds no $XPL . Pays fees in USDT, not gas tokens. Stablecoin-first infrastructure means nothing here. The chain processed thousands of TPS that second. Her mistake: two of them.
Customer already left. Probably checking Plasma One now, wondering why double for a phone case.
The Send button still looks harmless.
