I don`t understand this "commitment" thing those guys are talking about.What is this?
Two guys are sending each other a bunch of code.It isn`t very user-friendly, i think.
By the way,i don`t see the coffee purchased with this transaction delivered.
Many people have concenrns about offchain transactions security and double spending issues.
Are offchain transactions secure enough?
