FWIW, Yelp advertising has no effect on reviews. Allegedly some sales reps claimed that they could manipulate reviews, but such claims would have been empty threats/promises. This has been tested in court several times; see e.g. the 9t

Ethereum could use SNARKs to verify certain computations more efficiently, but the purpose of PoW miners isn't really to verify computations, it's to make a 51% attack expensive. CODA protocol uses SNARKs to verify the entire bloc

That's not an inherent limitation of PoS; PoS systems can be either AP or CP. Most PoS designs go with CP, but NXT and Ouroboros are examples of AP PoS systems. They use Nakamoto consensus, much like Bitcoin. It's true that Ethere

In most PoS designs, registering a new validator account takes some fixed amount of time, just as a measure to prevent grinding attacks. If registration takes an hour, and I can't predict the random seed an hour in advance, then I can&

Or double spend. E.g. you could send coins to an exchange, cash out, then mine off an old block to get your coins back.

It sounds like the money is going through the NIST and NSF, so presumably any resulting research will become public. If the government wanted to keep the research secret, I would expect the money to go to the CIA or somewhere else.

I think it can be rational for an investor to forgo productive assets, even if they have no opinions about market timing. They might look at a company, estimate its lifespan, estimate its total inflation-adjusted earnings over that period,

That's also true of fiat currencies though, yet Berkshire Hathaway is holding seething like $130b of cash equivalents. Granted, fiat has some major advantages: momentum, required for taxes, no capital gains tax, etc. But neither is a p

Is your concern that the algorithms involved in schemes like Shasper might not be correct, or that their economic assumptions about attacks might fail? I think it's very unlikely that any of the theoretical ideas behind Shasper are inc

There might be some constant factor penalty, but we can shard BFT systems much like we do with Paxos etc. See Shasper for example -- it won't have any practical limits on throughput.
