Thanks for your response and links.
I think the
difference is that those proposals all shard the mining work, whereas
what I wrote in my post shards the coin itself. In other words different
parts of the coin space are forever segregated, never ending up in the
same block. It's a big difference conceptually because I could spend
money and a fraction of it makes it into a block in ten minutes and the
rest two hours later.
And I think that's where the
potential for the scalability comes in. I am not really scaling
Bitcoin's present requirements, I am relaxing the requirements in a way
that leaves the users and the miners happy, but that could provoke
resistance by the part of of all of us that doesn't want digital cash as
much as it wants to make history.
All the best,
Akiva
P.S. Thanks for pointing out that I hit "reply" instead of "reply all" earlier ...
