Framedragger: heh, speaking of 'provably fair' and location in question (tallinn), they've been doing e-voting (for all major elections etc) for a few years now. iirc code audits showed weak spots, multiple sek0rity expert teams, advisory bodies etc recommended to shut it down because it was unsafe, but proud estonia knows better.. :p

asciilifeform: (in the case of 'provably fair', he can be shown the seed for the prng, but there is NO way for the casino to demonstrate that NO ONE ELSE KNEW it. hence -- just as promisetronic, and now on top of it all braindamage of using prng)
asciilifeform: the cryptographic mega-puzzler would be re how 'ck coin' could be 'provably fair' (i.e. the ciphertexts provably represent privkeys containing the entire monetary base, in aggregate )
mircea_popescu: not that expensive to make it provably fair though.
danielpbarron: the poker thing need not be "provably fair" it only needs to have WoT integration -- not unlike Eulora
asciilifeform: mats, mircea_popescu, et al : just about any game can be played 'over bitcoin blockchain' and be 'provably fair', this is not the problem, but that ~nobody wants to pay the cost (in time and coin both) of playing over btc telegraph.
mircea_popescu: nice font o.O. who's scws. where's the provably fair link ? why would i play roulette, i don't want to give you 5% or w/e the fuck the edge was. 1% is generous, this is not 1750.

asciilifeform: the whole 'provably fair' thing
dr_love: is there any value in a provably fair bitcoin lottery?
mircea_popescu: i mean what's the advantage to rolling this dice as opposed to roling a proper, provably fair dice ?
asciilifeform: 'provably fair' ?
mircea_popescu: right. specifically because it's not provably fair :)
mircea_popescu: benkay this has the advantage that it's a provably fair stochastic process.
asciilifeform: idea being 'provably fair exchange'

assbot: Flawed Provably Fair Systems

mircea_popescu: 1. Client changes the seed after each new server seed, before every bet. He doesn't know server seed, so seed he provides should give a random number. (Painfully tedious, few actually do it, but for those who do, provably fair.) << prolly a bot that does this would be useful.
punkman: I want to make a nice provably fair baccarat game. Get all those chinese bitcoins.
assbot: Provably Fair System - Pastebin.com
Namworld: Re what I was talking about the other day concerning provably fair systems. To be fair, most casinos do the same thing re providing new server seeds after user's seed.
BingoBoingo: Essentially all provably fair schemes come down to an evaluation of the implementor's reliability.
assbot: Is PrimeDice really (provably)fair? Well, it isn't.
Namworld: I think he mentioned at some point the provably fair system for PrimeDice would be modified for a 4th version of the website, but eh
BingoBoingo: Namworld: Well, a casino operator could "take a gamble" by offering a player a result to the player's detriment that is not provably fair
BingoBoingo: "Provably fair" is a tool to mitigate the risk.
BingoBoingo: The thing about "provably fair" is that like all other transactions it is an offer from one party to another.
Namworld: Provably fair should imply that any cheating possible under any scenario is possible to catch.
BingoBoingo: Well, "provably fair" offers some room to choose particulars, but... Can have problems
BingoBoingo: Provably fair should be so far below the minimum.
BingoBoingo: Provably fair ought to be the bare minimum. It is a shame people consider themselvesserious without it.
Namworld: Yeah, as I said, a properly done provably fair system doesn't prevent cheating/stealing. It just makes it impossible to do without the possibility of getting caught.
BingoBoingo remembers TradeFortress constantly advocating beautiful provably fair systems and just... Running with the money...
Namworld: It's more the implementation of their provably fair system.
Namworld: A true provably fair system doesn't need EVERYONE to check and doesn't allow any scenario where a cheated bet is impossible to notice.
Namworld: because you can still change the client seed before each bet, making it provably fair. The problem is if you don't, you can be cheated and it's impossible to get caught.
pankkake: lol, people are betting on a non provably fair site?!
Namworld: So, PrimeDice still isn't provably fair... Should I bother calling Stunna on it until he fixes it?
pankkake: so investors would have to chose between less volume yet provably fair, vs. more volume but maybe some stealth stealing
mike_c: bam, provably fair
ThickAsThieves: for example, if "state lottery" takes up "provably" fair
ThickAsThieves: design a provably fair casino that cant steal from anyone
ThickAsThieves: the topic is whether provably fair is provably a fiat gambling killer
mircea_popescu: ThickAsThieves actually that's a valid approach, mike_c's. i'd just like to explore the provably fair angle, from bettors prespective
fluffypony: thus as it stands right now provably fair is "provably making payments", not provably fair in the absolute sense
fluffypony: I agree with ThickAsThieves - I think "provably fair" often means "proving that there are winners and losers"
ThickAsThieves: this may allow some forms of provably fair, but many creative ways to game that otherwise
mircea_popescu: the provably fair thing will sink fiat gambling, only, they don't know it yet.

pankkake: "the first Bitcoin-only gaming establishment to offer unique, provably-fair games" is true if you account for "unique"
mircea_popescu: "CasinoBitco.in (CBTC) was the first Bitcoin-only gaming establishment to offer unique, provably-fair games along with a full Sportsbook. Operating successfully since May 2013"
asciilifeform: always seemed to be like 'provably fair' dice is inherently at odds with sane rng.
mircea_popescu: "Their roulette is technically provably fair and they are publishing complete results from previous day. But they are cheating in such naive way that they simply change outcome of roulette game when needed and later in published results from previous day they show different outcome, which is correct one but was not used."
jurov: even better if it is provably fair
davout: what we need is a provably fair ponzi
benkay: got some trash to talk on someone's provably fair gambling setup, nubbins` ?
nubbins`: are casinos provably fair with 1% house edge, tho?
pankkake: is gribble provably fair?
mikaeldice: I'm not too worried about this one.. "How Does Dicelead Proof Us Each Roll Is Legitimate? dicelead is provably fair which mean you can verfiy each roll is absolutely fair ,so we are only run dicelead.com for fair purpose and no way to change any result of it" ah, well, okay then
mircea_popescu: provably fair gambling is so far the most notable practical use of the blockchain.
lyspooner: or how about a more general questions for the group here: are there any bitcoin companies that use the blockchain in unique ways and produce revenue, other than provably fair casinos or notarial services?
casinobitcoin: a2: the provably fair? if so let me know
mircea_popescu: nubbins` was the hat provably fair ?
mircea_popescu: http://media.oglaf.com/comic/bugfuck.jpg << provably fair odds.
mircea_popescu: in fact, a blog dedicated to random-weekly audits of provably fair betting sites would be interesting
benkay_: seems like nobody's auditing these "provably fair" operators
pankkake: it's provably fair technically
mircea_popescu: the provably fair thing can be as subtle as good cryptography.
pankkake: they have the usual provably fair thing
parseval: The differentiator would be the technology being used and provable fairness.. HeroEngine, for example, is what SWTOR is built on. Build on that platform and other sites like Dragon's Tale would fold up as their players move to the modern, provably fair game
parseval: A group of developers could pool together the licensing fee and develop the game with provably fair methods at a 5% house advantage, then crowdsource the betting pool ala just-dice, keeping 2% for themselves for management and maintenance
kingofsports: his games are not provably fair just the general audited RNG bullshit, i dont play but its funny cause i so want to prove over a sample of 100,000 rolls that his game is -EV
ThickAsThieves: provably fair?
noaccess: "we have winklevoss" means that people used to talk about the possibilities afforded by bitcoin. provably fair being one. smart contracts. other stuff I read about. now it's all gimmicks.
ThickAsThieves: so far my assets are all "provably fair" at least ;)
Namworld: These new dice games require only a single payment, and retain the provably fair element. Then people can spam the bet button 10 times a second. Quite addictive.
fiat500: by being provably fair
mircea_popescu: with dice it's provably fair.
Bowjob: Mhm, is the free button provably fair
mircea_popescu: it makes prices be provably fair
