I'd just first like to say that I love reading your work. I'm always delighted when I see an update on Shtetl-Optimized and I admire how you are both simultaneously rigorous and funny in your papers and posts. Your PnP survey stands out in my mind as a truly fun and insightful read in particular.
Two questions:
1. Any meaningful updates you'd make to the PnP survey today?
2. As a total aside, I'm curious for your thoughts on blockchains. Not specifically proof of work as a BFT system per se, but more broadly curious to what degree you think "trustless" transactions and data processing might or might not be transformative.
Apologies in advance if you've recently provided thoughts on either of these topics and I've sadly missed them!
