What I mean by "large" is "prepare to conquer the world and displace major existing asset classes, including the US$. And the existing architecture is not going to be able to do that. The lightning network might be able to do that, but we will have to see what happens in practice. At present the lightning network is still pie in the sky. The way it might work is that there are seven billion client wallets, a thousand important peer wallets, a hundred very important peer wallets, and ten very important peer wallets. Every client wallet has a lightning connection to a peer wallet, usually an important peer wallet. Every peer wallet has a lightning connection to an important peer wallet, and often two or three important peer wallets, Every important peer wallet has two or three lightning connections to very important peer wallets. Every very important peer wallet wallet has a lightning connection to every other very important peer wallet. Worst case money transfer is that your client wallet talks to an important peer wallet, the important peer wallet talks to a very important peer wallet, which talks to another very important peer wallet, which talks to an important peer wallet, which talks to the client wallet of the person you are paying. --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
