mircea_popescu: this will be our debate all through the rest of this decade.

mircea_popescu: confucius says, as bitcoin transitions from 1k to 1mn usd per it will be impossibel to discern whether usg idiocy or bitcoin coolness is pushing the change

mircea_popescu: well, whoever was left after they hired among libertards for website coding skills.

mircea_popescu: you think it is fake, and you'd think it'd have to be fake.

mircea_popescu: i dunno why people are so butthurt over how stupid they are. of course they're stupid, nobody smart voted for the guy.

mircea_popescu: ;;later tell smickles any idea why mpexbot chokes on $vwap ^OIX ? everything else works

mircea_popescu: "enjoy the luxury of living alone"

mircea_popescu: but i can envision when we finally get ai that'll be how s.ai will sell it :

mircea_popescu: even if they live in a sort of gay house, with a house mother, it still takes > 3

mircea_popescu: this, incidentally, is why i see no future for the family of two. by the time all is said and done, living in new york today requires the pooled resources, chiefly intellectual, of about six average kids

mircea_popescu: this is true. merely being retarded is a bar constantly moving up.

mircea_popescu: and it's nowhere nearly as important a thing.

mircea_popescu: i guess we will likely live to see the best part of it anyway.

mircea_popescu: gravity, fire, these are things that beat so many cavemen across the skull it's ancestral memory

mircea_popescu: no see, because the mains have good precedent in the fire.

mircea_popescu: i doubt the girl's story will actually come i nthat form to the fore.

mircea_popescu: a lot harder to digest.

mircea_popescu: not any harder to implement

mircea_popescu: i suppose going forward this universal subservience of all people, institutions, mechanisms and consjiderations to bitcoin will be the hardest thing for the population to digest.

mircea_popescu: NOT for academia to tell it how to do bitcoin

mircea_popescu: yes asciilifeform , but bitcoin is here to tell academia how to do academia,

mircea_popescu: there must be urgently implemented a pillory system in academia. the top 10% get funding, AND the bottom 10% get tgo spend a day nude with their necks in the thing.

mircea_popescu: "your asics won't be useful anyway by the time anyone gets around to getting changes in that brick it"

mircea_popescu: asciilifeform the latter.

mircea_popescu: anyway. this article should be condensed into a two page job application with an asic producer and ditch all the "research" presumptiousness and otherwise opining.

mircea_popescu: perhaps that call was based on the mistaken belief that asics are more durable goods than toilet paper, which has been proven not to hold.

mircea_popescu: this actually was rejected by everyone on the grounds that it makes the stuff so easily brickable by even the slightest cosmetic changes in the "spec" (ie, code) that it's not worth it.

mircea_popescu: Overall we see that we can save 18 additions: 16 additions have a constant equal equal to zero, and 2 more additions with 0x80000000 which can be replaced by flipping one bit, the cost of which is very small (in hardware) when compared to the cost of one addition.

mircea_popescu: anyway, the c oncept of amortised cost of hashes used in efficiency of computation calculations is a sound way to go about things.

mircea_popescu: still the improvements are slight. save 2.x rounds out of 64, that's a 3% gain

mircea_popescu: tho in fairness maybne they were braindamaged/didn't have the time to do it properly

mircea_popescu: because it came out that all the logic needed to do this would actually increased cost and lowered efficiency of the chips

mircea_popescu: this actually has been discussed but not included by at least two asic developers

mircea_popescu: and we can early reject most cases. Only in 1/232 of cases we need to compute 62 rounds in the third compression function. Then only in some 1/260 of cases where we have actually obtained at least 60 zeros, we would need compute the full 64 rounds.

mircea_popescu: We basically want to force values created at rounds t = 60 and 61 to two fixed constants which come from the SHA-256 IV constants, and which would produce zeros at the output. For this most of the time we just need to compute the first 61 rounds out of 64

mircea_popescu: afaik this has been done since the fpga days right ?

mircea_popescu: We can reduce the cost factor from 3.0 to 2.0 almost instantly by making the following observation. In the process of bitcoin mining the first compression function does not depend on the random nonce on 32 bits. Therefore we can compute it once every 232 nonces. On average we need

mircea_popescu: statistically speaking it's likely to increase its meaningfullness

mircea_popescu: who ARE these people.

mircea_popescu: yea you dorks. totally "excessive". herp.

mircea_popescu: An interesting peculiarity in Bitcoin specification and source code is that hashing with full SHA-256 is applied twice. This may seem as excessive: one “secure” hash function should be sufficient. It also makes our job of optimizing bitcoin mining substantially more difficult.

mircea_popescu: these aren't the same rthings omfgbbq

mircea_popescu: "We recall from Section 6.2 that new bitcoins can be created when the miner succeeds to hash some data from the bitcoin network together with a 32-bit random nonce and"

mircea_popescu: dude who the fuck writes like this, this is not highschool yet.

mircea_popescu: i'm half way through

mircea_popescu: Back then it was 256 million times easier than today to solve CISO puzzles. Many early adopters of bitcoin have made a lot of money. One of the well-known problems of bitcoin is the problem of hoarding: a substantial proportion of bitcoins in circulation is not used.

mircea_popescu: i'm sorry, this isn't a paper. i'm not sure theverge would publish this muck.

mircea_popescu: "The energy efficiency of bitcoin miners have already been improved by a factor of about 10,000 since bitcoin have been invented, and we claim that further improvements are inevitable. Better technology is bound to be invented, would it be quantum bitcoin miners."

mircea_popescu: "In this paper we point out that there are fundamental incertitudes which depend very strongly on the bitcoin specification and that this is specification is NOT written in stone, it is likely to change"

mircea_popescu: why show bias in the first para when you're trying to play the researcher ?
