I want to say a little bit about retail payments. This is pretty important info and I don't know why Brainbot team doesn't discover this aspect. And nobody talking about that.
Everybody thinking that bitcoin + lightning will be good when you want to buy coffe at Starbucks or couple donuts.
It's only a half true. Let's dream bitcoin lightning working nice and everybody want start to use in retail payments. But they cannot do this, because bitcoin layer 1 in unscalable and have only 7tps. Always when you need open a payment channel you need to make onchain transaction this is make lightning network in bitcoin economically terrible.
Layer 1 in etherium is scalable! Brainbot team contribute code in sharding implementations, because they realize that fast layer 1 make layer 2 ( raiden ) more efficient. U can connect to payment channels fast and cheap anytime.
This is a big info scam over bitcoin in retail payments thru lightning. Etherium with raiden will be a king in retail payments. In near future your coffe at Starbucks will be paid by etherium thru raiden.
