I'm surprised that there is not a single significant thread discussing mimblewimble in detail, or even a healthy debate going on.
Considering how this feature brings many functionalities that Bitcoin desires for a long time, I was hoping for a wider discussions going on the forum. Instead I just found a few one-page thread and a couple of press releases.
I read the link on coindesk - confess it's also the first time I've heard of MW. Apart from the rather odd essay on why women should be more involved in Bitcoin development (what's stopping them, men?), it's one of the more well-cited articles.
I venture that MW's never been properly discussed because it's a sidechain and from what little I understand about this idea... there hasn't been a solution for incentivising sidechain miners (how do you call them?). Are they going to want to maintain it for pennies (rancourous boos ensue)? Or do they settle for huge block rewards that mutate MW into an altcoin (hisses ensue from "core")?
