The Lightning journey begins

I like Bitcoin. I came across it for the first time many years ago while paying for a coffee in Paralelní Polis. Over time it became too expensive to pay for a coffee by Bitcoin itself. To solve it I installed Breez wallet to be able to pay small amounts using Lightning network and a bit later I made the first payment. Where else than in Paralelní Polis.

Last week a friend of Honzík came up with the ideas of selling home-made lemonade on a street to make some money and to have some fun. To give you a context, Honzík is my 7 years old son. We immediately started supporting the idea and proposed help with all the necessary arrangements like a stand, a product which will be sold, how to make some PR and I proposed to support the idea by allowing their customers to pay by BTC and LTC. But based on my own experience, I knew that BTC blockchain itself is not the way how to pay 10 CZK (~900 sats today). I needed a cheaper way how to pay 10 CZK using BTC.

My very first idea was to create a payment request in Breez wallet, print the related QR code on a sheet of paper and done. I started evaluating the idea and found some shortcomings:

  • Breez wants me to keep the application opened until the payment is finished.
  • It’s not a good idea to re-use the generated lightning invoice if you do not want to lose your money.

So I decided to have some fun as well and started installing my own “lemonade” Lightning node to be able to generate my own Lightning invoices. Today my node is live for the 3rd day and I am going to share my Lightning journey here.

And BTW the guys‘ lemonade stand was a great success even without the BTC payments. So imagine how it could have done if they had it!
