Thanks for the kind words. In a sense, it's an alternate form of Proof-of-Stake. As Section 8.4 explains, the conventional wisdom is that Proof-of-Stake's flaw is that it's circular. We've proved that actually it's

Yes, hard to find anything more rewarding than that. Here is the prior HN story on it, if you're interested: https://news.ycombinator.com/item?id=12010760 I wrote about it for the Washington Post, as well: https:&#x2F

Thanks for giving me an excuse to discuss Sherdog on HN! They're the two places I hang out most. Somehow, I suspect the intersection of their user bases is pretty tiny...

Sherdog has suffered a lot from losing traffic to Reddit. The main forum still has enough users that it superficially seems similar to how it was 10+ years ago, but the subforums are dying. F12, the grappling forum, used to be one of my fav

Funny, I posted this today specifically because HN prompted me to. Not sure what led to my submission of the BBC article from 10 months ago being targeted for a re-post. But thanks for the link to the earlier discussion!

As an American who spent a year as a visiting researcher inside Russia's Foreign Ministry, I can confirm that these differences in decorum are very real. They are common knowledge in Russian society, and Russian diplomats are trained t

Howdy Scott, Is anyone in your field working on the implications of computational complexity for normative ethics? Hume's guillotine relies on the impossibility of any evidence for or against moral facts, but one could stipulate to tha

These are great questions, but I feel awkward hijacking a thread that isn't really about my experience. The Dateline NBC episode does a great job telling the whole story, including how I got involved. My Washington Post article explain

I find this to be an eminently reasonable perspective, which did not deserve to be downvoted. Existential anxiety can be extremely debilitating. If one plausible interpretation of time brings you comfort, there's no harm in focusing on
