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

Not a ready implementation yet but the mimblewimble protocol solves a lot of the scalability issues plagued in other blockchains.

Maybe I am understanding this imperfectly, but this hides how much you are paying, and thus how much you have, but does not hide whom you pay it to. Suppose HHitler create an evil fascist website, and requests donations in mimblewimble coins. Let us call the public key advertised on that evil fascist website HHitler. Ann buys mimblewimble coins on an exchange, using US$, and has to give her true name and an image of her true face. Won't the mimblewimble blockchain show that Ann gave an unknown amount to HHitler, whereupon antifa goes around and kills some girl whose face superficially resembles that of Ann, and then the judge lets them off as well intentioned good guys? As the judge recently let off a black man who killed a white man and then took his wallet, and subsequently claimed, without racist inconvenience of actually needing to produce any evidence, that the white man had called him a n****r --- This email has been checked for viruses by Avast antivirus software. https://www.avast.com/antivirus
