For many years now we have been accepting Bitcoin (with zero confirmations and directly, not through Bitpay) at our bar/restaurant in Berlin. Today we have deployed a testnet lightning node and accept testnet coins via the lightning network from a few customers to get a glimpse into the future. And that future looks shining bright!

- No more waiting for the customer's transaction being broadcasted, transactions arrive in milliseconds, not seconds (or sometimes minutes in case the customer uses coinbase or another bank wallet).
- No more looking out for double spend attacks. Not even Peter Todd is going to RBF us on LN.
- No more confusion during times of malleabillity attacks. Transaction malleabillity is a thing of the past.
- Massively advanced privacy for us as well as our customers as only we can see the transactions on our payment channel.
- And we will finally be able to offer free-of-cost payments to our customers.

As a merchant I can tell you that every merchant on the planet wants this stuff. It is like after all these years Bitcoin shows that with LN it can live up to its promises in regards to efficiency, speed, irreversibility and privacy no matter how many people will use it.

Thanks to all the developers making this possible!

Hmm,

Did you record your Customers Names & Address when you accepted Zero Confirmations, in case they ever used a DoubleSpend trick on you?
(It is quite easy to doublespend on a Zero Confirmation.)

LN is not safe at all until segwit is activated, so you have to trust all of your LN Clients Completely.
Counterfeiting and stealing BTC thru LN is not only a possibility but a probability.

Little word of warning , not waiting the required confirmations, is like playing Russian roulette , it is not a matter of if but When!

Smarter move on your Part would be using a Gift Card System , that people can fund with BTC instead of taking BTC directly.

Cool
