Neil: http://bitbet.us/bet/596/btc-difficulty-to-increase-by-less-than-10/ << Time for the difficulty bulls to get worried?
Neil: <mircea_popescu> Neil since you mentioned jtd, you ever read the original mpoe prospectus ? << I have, probably twice. What's the connection?
Neil: Damn these blocks getting scarce
dub: fuck you bitcoin, fuck you in the goat ass
nubbins`: almost too perfect to ruin
nubbins`: so there's this escrow guy on the forums, saltyspitoon
dub: I tell you
dub: every time
davout: ;;later tell mircea_popescu deposits pl0x
MisterE: looks like Stamp is the new king
BingoBoingo: Like Blockchain.info when from being useful, cultured manure to straight up salmonella liquishits
MisterE: when their news was poop
MisterE: the start of this down trend
MisterE: last week they were the big news on Bloomberg
VanCleef: i'll remember that for next time mats
Mats_cd03: whatever the tx fee in the ref client is, double it, problem solved
kakobrekla: meh, blockchain buys rtbtc, everything goes to shit.
VanCleef: ok, not a test network
cads: VanCleef: a test network holds no market value so it'll confirm quick but mean zip
Mats_cd03: pay a higher tx fee then scrub
VanCleef: i sat with a guy for 8 hours at starbucks once and i ran out of things to talk about about an hour
VanCleef: its just awkward when doing a face trade with someone and they ask if they can sleep over while waiting for it to confirm
VanCleef: i think so?
cads: VanCleef: sounds like you want to set up a kind of test network?
cads: whatever that means :)
cads: I want to see a cryptocurrency backed in automated service provider contracts
Duffer1: riecoin's pow attempts to find prime sextuplets to generate absurdly long prime numbers
VanCleef: is it possible to have a alt coin that doesn't require any miners to verify it? once its sent its instantly confirmed?
BingoBoingo: NMC was thought to do useful shit, but miners won't commit transactions with useful data
cads: same here but I have to say it's intriguing
Duffer1: ya, i must disagree with that position
cads: MP's conjecture is that it must trade off utility between Pow and the secondary function
MisterE: NMC does useful stuff too
Duffer1: primecoin has already proven that hashing can produce utility beyond PoW
cads: for a really weaksauce example, say I take the square of a number x. In the result I've also computed the square of the number -x, and this for 'free'.
cads: Duffer1: I do feel like we're arguing more from philosophical/economical principle that computation shouldn't give us two things for free - but this seems false.
Duffer1: cads read the Reicoin whitepaper you'd like it ^.^
Duffer1: MP read the Primecoin whitepapaer you'd like it
mircea_popescu: anyway, im wiped. we'll have to continue this tomorro
cads: mircea_popescu: we'll have an epsilon for each target problem, and maybe the cost of solving al the target problems starting from A must be greater than or equal to solving B, C, D... seperately.
MisterE: not that I have ever done that to a cat
MisterE: Whale is swinging it around like a cat by its tail
cads: suppose we have algorithm A, and we have that a solution of A reduces polynomially solutions B, C, D, E, F, G...
mircea_popescu: "turn this wheel and an egg will fall out every revolution, then look if any eggs have feathers attached" is not okay
mircea_popescu: "turn this wheel and an egg will fall out every revolution and also a feather every ten revolutions" is okay, whereas
mircea_popescu: byt the idea here is that we promise some sort of result in the future.
mircea_popescu: you can in principle sift through the history and find convenient cases for any particular problem
mircea_popescu: and importantly, this is looking forward in time.
cads: that's the only place for the e to come from, isn't it?
mircea_popescu: well wait, that's hiding the ε ?
cads: mircea_popescu: to formalize this completely we'll have to assume something like a polynomial time algorithm that converts the output of algorithm A into a solution for problem B.
mircea_popescu: cads something like that
cads: "Hypothesis: if an algorithm's output provides proof of 1 unit of work, and that output is also usable to provide the equivalent of epsilon units of useful work for another problem, then the energy expenditure of the algorithm must be greater or equal to 1 + epsilon units of work."
mircea_popescu: i suppose actually my lemma may end up the equivalent of quantum indeterminacy, but for maths.
Duffer1: afaik the outcome of either cannot be guaranteed to yield a useful result beyond PoW
BingoBoingo: mircea_popescu: Well, most minds have their head splints set to promote that nowadays.
Duffer1: Riecoin is the one for large primes
BingoBoingo: cads: Primecoin isn't even that cool at finding useful primes
cads: mircea_popescu: I feel the same here, for the opposite side
mircea_popescu: cads but would we be able to trust the results
BingoBoingo: mircea_popescu: Your lemma is sensical so long as it is restricted to hard POW's
cads: mircea_popescu: I think we should be able to test the hypothesis directly against the primecoin if we try hard enough
mircea_popescu: to me it's quite straightforwardly obvious but im much too wasted to be able to show it.
BingoBoingo: In a world with Auroa coin and Mazacoin... THere is a good chance random graphs might mine better in tard efforts at implementation
cads: mircea_popescu: I don't feel it mathematically yet but I feel why we'd like this to hold, economically
mircea_popescu: ie, if on average your useless-pow block costs 1, the useful-pow will cost 1+ε, where ε >= the useful
BingoBoingo: I mean for the first set you could probably encode information much as RSA does. I don't have enough vodka on hand to speculate if that would be a good idea. Most of Elliptic curve cryptography works on spaces that can be played with in graph theory world though.
mircea_popescu: should an algorithm exist to resolve the problem of ts on randomly distributed graphs, an application of that algorithm on a selected set of graphs with a useful application will cost more than the normal by an ammount at least equal to the cost of computing the useful application.
BingoBoingo: For most naive attempts at implementations the second set would likely be simpler and cheaper than the first
cads: BingoBoingo: right, I'm to tired to do that rigorously or even tell if why I said even makes sense.
mircea_popescu: cads not at all. my lemma is more general, in your proposed terms it would be :
BingoBoingo: Also ironic, how pissed would the whales be if they knew we used the same word for our losers and their dicks.
cads: well lets see a better example. Problem 1 makes us solve the travelling salesman problem on random graphs. Problem 2 makes us solve travelling salesman on maps that appear indistinguishable from the first ones, but in fact encode valuable information in their solutions. For your hypothesis to be true, it should be impossible for the second problem to cost less energy than the first?
BingoBoingo: Indeed. Most of the really big breaks in computational theory cam from the women before the dorks realized they could make their own fantasy worlds.
mircea_popescu: a bit ironic because the poor woman suffered plenty through being a woman. ended up teaching under hilbert's name because the sort of boneheads roaming about end of 19th century couldn't have a woman colleague
BingoBoingo: mircea_popescu: Once they hit the crystal... It's just safest to assign them the pronoun that inspires the least sexual interest.
mircea_popescu: possibly the smartest woman that ever lived.
mircea_popescu: cause really to work as advertised or is no good
mircea_popescu: cads no but the key is your "or". turn it to "and" and see.
cads: i don't see it because regardless of the supposed usefullness, the algorithm still uses 2^k energy.
BingoBoingo: The rejected hashes might already contain that play.
cads: mircea_popescu: it's without question that anyone can look at the outputs of the two algorithms and verify that ~2^k energy was expended. Perhaps the problem happens when we require the second algorithm to also guarantee a useful output relative to the third party.
mircea_popescu: i imagine after enough btc blocks, we'll actually get shakespeare's merchant of venice in the hashes, so why not
mircea_popescu: cads but if it's purely coincidental then you don't have a pow that does protein folding, you just have a pow that occasionally folds a protein
mircea_popescu: anyway, it's clearly interesting. or as the romanian expression goes, "un prostovan arunca o piatra in apa si zece filosofi se chinuie s-o scoata"
cads: I feel the value supposition must be completely independent and coincidental to the energy requirements. You could even suppose it is pure coincidence the output of the second algorithm is structured such that it's useful to the third party.
cads: Now suppose both solutions are verifiably by a third party in polynomial time. But suppose additionally that the answer for the second problem also has a value of $100 to the third party. The question is should the second process take more energy to compute?
mircea_popescu: BingoBoingo no we want like emmy noether for this shit
cads: let me offer a counter "you can solve a partial hash collision problem (something like an O(2^k) expected running time), or you can solve a np-complete problem requiring brute searching a binary tree of height k (assume similar expected chance of success)."
mircea_popescu: something like the 2+2 = 4 2*2 = 4 sorta thing.
BingoBoingo: Shame Erdos and his bog bag of meth are out of the picture
mircea_popescu: and actually this could probably be expanded into interesting results for ppl trying to understand various higher level maths. "define a comutative algebra in which a ring can exist for which any addition also calculates a multiplication and vice-versa"
mircea_popescu: im probably restating well known and anciently established mathematical fact, but here, mp's lemma : any computation of two results can be reduced to two computations of the respective results, and the sum of the energy consumed by the latter will be at most equal to the energy consumed by the former process.
mircea_popescu: now. does this mean your key will simply have to be twice as long for equal security ?
cads: this would be neat to model, and may well be true in a very theormodynamic sense
cads: mircea_popescu> this could be understood on a macro level as "if there are outside constraints on your pow process, you'll need that many more iterations"
mircea_popescu: no but you're math-literate, how would this work ? you compute two things with the same stone ? what's the idea here ?
mircea_popescu: im not debating whether it's interesting, it's definitely interesting. i'm just saying it;'s stupid. stupid things are usually interesting, at least as amusements
cads: the author does provide me with say 30 bits of novel information (I had not known of prime coin - the paper is interesting)
mircea_popescu: this could be understood on a macro level as "if there are outside constraints on your pow process, you'll need that many more iterations"
