Fine talk for those doing comparisons of Monero vs the Zcash family regarding privacy etc... ---------- Forwarded message ---------- From: Tom Mitchell <mitch(a)niftyegg.com> Date: Mon, Sep 25, 2017 at 7:29 PM Subject: [Cryptography] Zerocash: Addressing Bitcoin's Privacy Problem GoogleTechTalks To: cryptography <cryptography(a)metzdowd.com> A google tech talk on YouTube. https://youtu.be/uEdx-pqJg4I "...Google TechTalk, 8/28/17, presented by Alessandro Chiesa Abstract: In Bitcoin, a payment's details are broadcast in the clear, so that anyone can verify its validity. Unfortunately, this violates user privacy and sacrifices coin fungibility. I will describe the Zerocash protocol, which uses zero knowledge proofs to achieve privacy-preserving payments in a Bitcoin-like system. This protocol was recently deployed in the wild, as part of the cryptocurrency Zcash. "About the Speaker: Alessandro Chiesa is an assistant professor in the Department of Electrical Engineering and Computer Science at UC Berkeley. His research spans the areas of complexity theory, cryptography, and security, and focuses on the theoretical foundations and practical implementations of cryptographic proof systems such as zero knowledge proofs. He is a co-inventor of Zerocash and co-founder of Zcash. He is an author of libsnark, the leading open-source library for succinct zero knowledge proofs. He has received a Ph.D. in computer science from MIT in 2014, and B.S. degrees in computer science and in mathematics from MIT in 2009." ========== Zerocash is not the only one looking at this. Laws that apply to banks protect a lot from all except governments. Will governments balk if this gets too good? -- T o m M i t c h e l l _______________________________________________ The cryptography mailing list cryptography(a)metzdowd.com http://www.metzdowd.com/mailman/listinfo/cryptography

[WAR] [RUS] -- correction, Russia failed to invade Europe ... again
by Zenaan Harkness 26 Sep '17

Sorry folks, strangely, this one seems like just a false alarm it seems - sadly for the war porn enthusiasts, but thankfully for the EU, the Baltics and especially Poland (‼¡‼), Russia has once again failed to attack Europe under the guise of a military exercise. Oh well, another day, another possibility for Russia to invade Europe ... ** NATO Slitting Wrists After Russian Exercise Ends Without Anticipated Invasion of Europe http://russia-insider.us9.list-manage.com/track/click?u=fa2faf7034c3c3c413c… ------------------------------------------------------------ by RI Staff on Thu, Sep 21, 2017 After conclusion of the Zapad 2017 military exercises the Russian units participating are packing up and returning to their barracks: Russian troops have started to routinely return to their home bases after the end of the joint Russia-Belarus Zapad 2017 exercises that earlier provoked large-scale hysteria in the West over their nature, numbers and purpose. Units of the Russian Air Force were first to set off for home following the end of the drills, according to the Russian Defense Ministry. BBC, CNN and the Jew York Times all covering this fantastic day for the USA secret services in Syria (... <ahem> ... not) - NO gloating now folks, it's very unbecoming and just not nice!: ** ‘US Secret Services' Tried to Nab 29 Russian Troops in Syria ... and Got Their Butts Kicked - Russian Military http://russia-insider.us9.list-manage1.com/track/click?u=fa2faf7034c3c3c413… ------------------------------------------------------------ by Justin Huebner on Wed, Sep 20, 2017 Now this is something you won't see on NBC nightly news. The Russian military spokesman in this briefing, General Sergei Rudskoi, in a matter-of-fact deadpan, explains that 'US Secret Services’, and their Al Qaeda proxies, had a very, very bad day yesterday. Americans love bombing small, defenseless countries into the stone age, it’s part of their culture like baseball, apple pie, and morbid obesity. One of the things they never do, however, is pick on a country that can fight back. <echoes of James Clapper mumbling "but but, I was told Russians are --easy-- targets"> <"That's where you're wrong, kiddo‼">

https://juliareda.eu/2017/09/secret-copyright-infringement-study/ https://juliareda.eu/wp-content/uploads/2017/09/displacement_study.pdf The European Commission paid €360,000 (about $428,000) for a study on how piracy impacts the sales of copyrighted music, books, video games, and movies. But the EU never shared the report—possibly because it determined that there is no evidence that piracy is a major problem.

Just switch on your computer and twitter, post, troll, and hate away. Boss is base. Self-entitlement worldwide: that has been the credo of the virtual space riders of the artichoke cult since day one. Their enemies are evil dictators and inhuman regimes; their friends are the artichoke community and supporters. Their motto: make the internet great again. But what happens if the artichokes start attacking one another? If their compass is no longer calibrated? To make a pile of ashes from a forest, it only takes only a cigarette. To make the internet burn it takes only a tweet. No matter if fake, if fact, or fiction? Irrelevant, out in the open it goes! Hugh, I spoke. I don’t require counter arguments. I am already a democrat. Fuck the facts, you’re not my dad! May the enemy scorch in the purgatory of my projections. Burn, baby, burn! As an artist collective we contemplate the value of facts within our society. Our fictional narrative is (also) set in the middle of Berlin. Informed by a true incident of messianic hope for salvation and tribal justice inside the global village. We ask: who speaks out there for the privatized court of the internet. Who are the self-proclaimed cyber sheriffs? And why have they brought a giant wooden horse?

Re: new idea for random number generation
by Ryan Carboni 24 Sep '17

24 Sep '17

I am reminded of an anecdote (of which, our entire history books are made up of): https://unicornjelly.com/urulesmystories.html I have played a lot of Dungeons and Dragons, and related, games in my life. Rolling dice are an intrinsic part of such games, because they allow unusual things to happen, unusual results that surprise and amaze. Dice also give people the illusion of control over Fate...dice are random, yet people often feel like they are able to 'control' the probabilities, in a kind of real magick, some unexplained ability. When highly improbable events with dice occur, it is easy to believe such nonsense. Or perhaps we humans can affect probability...I will let you be the judge, for yourself. One time, during my days as a paid, professional DM, I had been running a free game for some people I was involved with at the time, and the brother of the person I was most involved with at the time came up to me and made a rather incredible statement. His friend was visiting, had heard of what fame I had back in those days, and wanted to meet me...and by the way, this friend could ALWAYS roll within one number of any target on a 20 sided die. Without fail. On any die. Any time. Sheah, my ass! Still, since the fellow was visiting, and since it really would not take any time to see for myself, and since he was a big fan of mine, I agreed to put up with whatever farce would be tossed to me. The first five or six rolls, each on a different die from my personal collection were all perfect and exact. The value '20', time after time. Then I borrowed the dice collection of an observing friend, doubting my own dice, despite the fact that I had painted them myself (you had to in those days) and knew my own dice inside and out (I have an enormous collection of polyhedral dice). The next five or six rolled I called at random....just picking numbers out of the blue. Whether it was an 18, or a 3, or a 12, or 20 again....this young man always, and without fail, on any die I gave him, (so long as it was a twenty-sided die, he could not do it on any other die) he could roll within one number. When I called 18, as I remember, he rolled 17, for instance. He never missed, not even once, and I must have tested him several dozen times. I wanted more, but he was getting bored, besides, I had run out of fresh, new d20's to use. We used every d20 anyone had. I would not repeat using the same die, trying to see if somehow the dice were rigged. He did not know how he did this trick. He just noticed, one day, that he could do it. He was not that amazed by it anymore. He had been doing it for several years. Adults could not care less, or refused to even bother to look. I was almost so skeptical myself, that I nearly shunned him as well. I am glad I did not, in retrospect. To this day I have no explanation whatsoever for what I saw. I tested the lads claim as carefully as I could, given the situation, and there was no shortage of witnesses from every angle. He did not palm the die, or do anything odd....several times I asked him to simply hold out his hand, palm up, where I deposited a d20, and had him just roll the die off of his palm, without closing his fingers. Just let the die fall off and hit the table. It made no difference. I have no idea what ever became of the boy, but I will always remember whatever it was that he could do.

new idea for random number generation
by \0xDynamite 24 Sep '17

24 Sep '17

Speaking of cryptography (harhar), I was contemplating an idea to generate random streams of random numbers using chaos theory (not the first), specifically the logistic equation [3.5x(1-x)], when I came across the argument (http://www.cs.utsa.edu/~wagner/laws/chaos.html) that such generators are "psuedo-random", but I don't think is true. The equation is capable of producing an infinite stream of numbers that get more random as you continue to use the equation. The amount of true randomness approaches the depth of your word size, but in theory you can create an implementation with arbitrary depth (say 10000 bits). Is this interesting to anyone? Marxos
