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: 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: 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: "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: 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 ?
mircea_popescu: he wants me to boycott "us bitcoin companies" meanwhile his blog runs on google. just that...
mircea_popescu: how they manage to write five pages of nothing that keeps changing every three months but somehow manages to miss that basic point i will never know.
mircea_popescu: the delightful ignorance of these two week old bloggers.
mircea_popescu: nubbins` send Namworld a tshirt with "other people get hotwives and all i have is this lousy hotmail"
mircea_popescu: i wonder if in a coupla years wikileaks type sites will have degenerated to posting unflattering shower pics of elected officials
mircea_popescu: i don't see who can be bothered to read the 5000000 pages of crap governments write
mircea_popescu: kakobrekla ironically, i would guess by now nobody cares anymore
mircea_popescu: basically it's 10x a year, 2012 was an error, shoulda been 30
mircea_popescu: monk takes a sip... sloshes it around, takes another sip and goes
mircea_popescu: so in order to pull a prank on him, some doods get him a glass fulla piss
mircea_popescu: this monk is famous for being able to identify any wine, by the vineyard, even by the vintage in most cases.
mircea_popescu: ya well, then you get slightly better or equal to chance
mircea_popescu: you try and pass contraband by a customs agent with 30 years in the field and tell me.
mircea_popescu: ThickAsThieves it's also bs. humans get close to 100%, provided they're not idiots.
mircea_popescu: once, the center of the world. nowadays, not even worth writing spam for.
mircea_popescu: wow. i just realised that at a population of 2mn, you could probably personally meet each girl that turns 17 during a year.
mircea_popescu: lol bitcointalk mods filled a post of mpoe-pr's with [expletive deleted]
mircea_popescu: kakobrekla tractors ? what, you drag the country further west if in danger ?
mircea_popescu: even if the bangladeshis decide to only fight with 17 yo women taller than 170
mircea_popescu: Namworld im pretty sure bangladesh flattens slovenia on headcount
mircea_popescu: fun fact of the day : slovenia spends on defense 500 mn a year. bangladesh, 1500.
mircea_popescu: because this was a thing, at some point people had trouble groking the concept that funny internet butts are intrinsically worth more than any fiat.
mircea_popescu: i recall distinctly ppl going "oh , it's wayt too late now that it attained parity"
mircea_popescu: lurkwingduck it's a living. not as good as stripping, but what's a boy to do.
mircea_popescu: Namworld notrly. great way for businesses run by idiots to sink themselves.
mircea_popescu: they just know vcs are retarded and are trying to milk it while it's good.
mircea_popescu: Namworld no, more like "if you say avalon is pretty scammy we will write down your address on our list of things we hate"
mircea_popescu: whatever was that dork's name that had a gambling list where he blacklisted everything (except scams) ?
mircea_popescu: ThickAsThieves basically this is a lot of pretense around the reputation scam people try to run on the forum
mircea_popescu: sometimes it's like they have a stupid competition going and we never fouind out.
mircea_popescu: well if you work for the press 10k is > your lifetime income.
