And now there's a peer-reviewed paper about designing machines with error tolerance so that everyone can mine butts 30% more efficiently:

Why not keep this to yourself and capture 30% more butt profit?

edit: it also relies on making GBS threads up the blockchain and having everyone else figure it out to reject the bad entries during validation.

I once jokingly told a co-worker it was easier for me to make him look worse than it was for me to improve my own performance while we were going over yearly reviews.

I guess the same applies here when you deliberatly shoot your competition in the foot and run off ahead.

Buttcoins encompass all the worst aspects of capitalism. Can't wait to see what happens when half of everyones computing power is now dedicated to loving over the other guy.

This contains such brilliant and incisive quotes as "...any reduced hash rate leads to a lower hash rate" and is basically buttcoiners.txt like you said. Instead of error checking any positives to see if they're false positive the newer more efficient designs discussed skip all that stuff, say "looks close enough to me, poo poo it out on the network as fast as you can" and if it's wrong let someone else figure out what to do with it.

Of course it's more efficient if you put your processing power towards just finding the next hash and force the rest of the network to do your error correction for you. They don't say that though, instead of saying it directly they dress it up with fancy words like it's a revolutionary new form of computing going to be the next big thing. Prisoner's dilemma all over again like so much of buttcoin. All the individual cares about is most efficiently grabbing the butts for themselves, so for them specifically it is most advantageous to spend their time/computing power figuring out another false positive instead and just hope that one's right while off-shoring the process of error detection. What happens when the entire network is composed of people making GBS threads out false positives constantly? Eh gently caress that who cares, gotta get more butts.

quote:

Butterfly Labs has a long and horrible history with their mining rigs. They started taking pre-orders over a year ago, with a ship time sometime in late July. After numerous delays in production, shipping problems and general incompetence, the only thing they’ve managed to get out the door are some of their tiniest miners, the Jalapenos. And those mainly ended up in the hands of reviewers and blogs in order to keep pumping the Butterfly Labs hype train and securing millions of dollars of pre-orders still in limbo.

Lucky BFL forums user Luke-JR however scored a sweet Mini Rig from Butterfly Labs (it’s just a coincidence he’s a driver developer for them I’m sure). This rig was originally promised to produce 1500 GH/s hashing power at 1500 watts for $30,000, but has since seen it’s hashing power slashed to a third of what was promised and it’s power consumption increased 75%, now just offer 500 GH/s at 2400 watts. They’ve promised to make good on pre-order buy sending out 3 rigs to match the initial hashing rate, so now it’s only 1500 GH/s at 6900 watts, a reduction in GH/Watt by a factor of 5.

That's cool as hell. I mean in theory not in practice, kind of like bitcoin in that way.

Uhhh, having the resources and/or connections to set up a third world humancoin farm would be a pretty huge advantage. Like way bigger than the ability to buy some GPUs.

The whole idea of "proof of work" only makes sense if it's work that has some value. Make a CancerCoin where you have to prove you have done work for a project like Folding@Home or something. The HumanCoin is just a dumber combination of something like ReCAPTCHA except the work done has no value, and the buzzword of the day.

I would love to see the sloppy mining practice become mainstream. If enough people do it (read: the two pools adopt the practice) then there's a solid chance some actual garbage will end up as canon in the blockchain. Depending on the sloppiness, maybe a lot. And then somewhere down the line, it becomes accepted that the blockchain is basically 50% invalid hashes or whatever. The hand-waving needed to address the problem at that point will be enough to power a small wind farm, which in turn will power more sloppy miners.

There was a Bitcoin startup that had the idea to run a fantasy stock exchange for companies that have yet to make an IPO and start trading on the market, like Snapchat or Uber, based on their estimated valuation. They were still in beta but had the brilliant idea of doing their beta testing by inviting friends, family, etc. to participate using bitcoin. Which immediately placed them under the scrutiny of the SEC for using real money (in the sense that exchanging bitcoins is a taxable event, similar to paying someone with stock shares) to gamble on non-existent securities.

Anyway, after the SEC reached out to them one of the engineers had the brilliant idea to post some data analytics on their blog.

No, they were purposely trying to give a big middle finger to the SEC after they were told what they were doing was illegal. I think they ended up with a $50,000 fine, which is pretty light.

They wrote some pissy blog posts too, I think, but I don't know where to find those.

If you have two big primes you can put them together in a way that's hard to figure out what numbers you started with and somehow cryptography comes out the other end.

Amazingly enough there sort of is such a guarantee. This famous theorem tells us approximately how many prime numbers are to be found when searching a given region. I don't know whether this approximation is good enough to want to trust your economy to (actual number theorists might or might not be able to tell you how likely it is to hit hyperinflation by running into an unexpectedly dense region of primes) but if you're running a Bitcoin variant, I imagine it'd be among the least of your problems.

That's actually almost entirely wrong. Testing if something is a prime is hard (it's in co-NP). Coming up with a reasonable guess of a prime is comparatively easy; guess a number and perform a cheap probabilistic check and if that fails add two and try again (doing this yields pseudo-primes which is what is used for encryption). That means the "worker" can just make cheap guesses while anybody proving they didn't cheat have to do more work.

But you're on the right track; something like butts might be a good way of solving NPC problems. That is basically any interesting problem; solving the problem is (most likely) exponential (slow!) in the size of the input while checking it is polynomial (fast-ish).

Primality test is in co-NP; proving that a number is composite is in NP; it is easy to prove that a given number is not prime: give me a prime factor; coming up with that factor is hard but checking is easy (integer division is fast).

Most optimization problems are in NP (compute shortest route, best packing of boxes in a car, mathematical proofs, ...)
