This is not meant as a heavy technical discussion. That's why I posted it here.
Since there is a lot of talk about 'The Lightning Network' at the moment, and a lot of confusion about
how it actually might be implemented in the real world, I thought a layman's description would be useful.
I'll start, and then some one, please correct me..
As I understand it, and from other lively discussions, LN allows Bitcoin users to go into a private room, transact amongst themselves with
100% security off the main chain, and then when all is said and done, they leave the room, and post a TXN on the main-chain that is the culmination / sum of all the private TXNs.
So - we can all play poker in private, with bitcoins, off chain, and then at the end of the night send out 1 TXN, on chain, with everybody getting their final chip stack. Very nice.
What I don't understand is how this works when I want to transact with someone on the street, or in a coffee shop ?
If I'm only really going to be sending them some BTC once, how does LN help in that scenario ?
