Re: Multisig Escrow Manager - helping users use advanced transactions
I took a quick look. Users that have a single address (web wallet usually) will get an error message if they try to do a repeated escrow transaction with the same buyer/seller pair because you will generate the same escrow address. Good thing you have an error for this , otherwise the release code would already be known to one party. Notify users to use a fresh address when doing escrow with the same buyer/seller.
Ooh, possibility to notice. Though I'm actually planning on having the server generate a fresh address and private key for the arbitrator to use, so there wouldn't be a chance of a multsig address repeats. (I have the server generate the arbitrator's key and give it to him so that the server can immediately sign the failsafe transaction with the arbitrator's signature. Then the seller would have no reason not to sign the failsafe transaction, so his signature is guaranteed. This means that the failsafe transaction will work even if the buyer and arbitrator refuse to sign any further transactions. It does mean that a malicious server could act as the arbitrator, but I think that's a small acceptable amount of risk. If enough people found this too debatable, I could add an option to allow the arbitrator to provide his own address, and I'll make sure that the arbitrator's address isn't already in the system in order to address the possibility you bring up.)Couldn't you have developed that a few days earlier?

Ha, funny thing is I've been implementing this on a coincidentally similar (even to the price) bounty given by someone else.I had set up a bounty for something like this

(Bit of criticism of knowitnothing's solution: in his, the server generates the private key that the payment goes to. It's just a regular single-key address, not a multisig address. The users have to trust the site to not run away with the funds. The server then splits the private key that it knows with a secret-splitting algorithm allowing any two users to create a copy of the private key. There's no way for the users to verify that the split-key values that they get from the server are valid until after the funds have been sent and they attempt to recombine the key to claim its funds.)
Multisig Escrow Manager - helping users use advanced transactions
I've been fascinated for a while by how Bitcoin is programmable money, and at the many protocol-enforced possibilities such as those on the Bitcoin wiki's Contracts page, but I've been disappointed how even years later most of those special transactions are still very theoretical not used much besides by a few tinkerers here and there. Even if you were in a situation where one of those types of contacts could be useful, you would have to spend most of your time explaining it to the other would-be parties and trying to convince them that you're not just trying to trick them somehow. It's a shame because a lot of those systems done right drastically reduce the possible risks by allowing the Bitcoin protocol to enforce rules. We need better tools and/or tutorials for this stuff.
I've recently been working on the Multisig Escrow Manager, a web application for managing Escrow transactions that will provide a communications platform for Bitcoin Escrow transactions, not too unlike other sites that I'm sure exist, but with the twist that you never have to fully trust any money to the site or the arbitrator. Instead, participants in an Escrow transaction give their addresses, the site generates a 2-of-3 multisig address (with a description showing how it can be verified) that the buyer sends his funds to, the site provides a simple communications platform for them to discuss the progress of the transaction and raise disputes in a way they can each see, and instructs them on how they can resolve the Escrow transaction by signing transactions for the funds in the multisig address. Any partially-signed transactions are displayed on the Escrow transaction page so other participants can easily find them and finish signing them. A failsafe transaction sending the funds from the multisig address to the seller with a lock_time set to a pre-agreed time is also generated, so if no disputes are raised during the time and/or several of the participants stop participating, the transaction can still automatically complete.
We've seen a lot of Bitcoin sites shut down with their users' bitcoins; a different type of site where that's not possible is surely valuable.
The Multisig Escrow Manager is live, though currently very much still under development. Most of the actual bitcoin/multisig stuff is incomplete right now. The system for organizing Escrow transactions and inviting other people to participate them is working. Feel free to test it out! (You can even act as multiple roles within the same Escrow transaction to test it out.) All of the source code is released on github under a permissive MIT license for anyone to use. It's not even too hard to install and run locally on your own machine (though some of the dependencies might not currently play nicely under Windows; I'll look into that sometime). Feedback is appreciated.

If only the recipient (and sender) can read a transaction, how can you verify that the transaction is valid and based on previous unspent transactions (that you can't read)? You then have to be able to verify those previous unspent transactions are valid by checking the previously unspent transactions they depend on too.
I can't imagine how any sort of anonymous system could work besides one that abused BIP 32 or used Zerocoin's innovations.

Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency
logarithmic scale on the difficulty chart might be interesting
Not really, just makes everything look more flat.
Yes, as a previous poster mentioned the difficulty isn't a linear measurement, so my hope with the logarithmic scale was to compensate for that. I guess that would be a natural log scale (base e, not 10).
If the data is already a sort of log-measurement, then doing another log-scale would just be doubling it up.
Why homosexuals would be more likely to rape little boys than heterosexuals raping little girls?
Call me crazy but there's no club called man girl love association but there is a 1 million strong man boy love association club which is getting serious funds and is growing very fast.
Why? If I had to guess I'd say that heterosexual males see perverts while homosexual makes tend to be sickos. I mean, you're walking around with shit on your dick all day, right, your ass is torn and bleeding and you're one ass pounding away from sizing up to a size 12 ass-cork before your shit falls out - that's pretty sick the way I see it compared to heterosexual men.
who the hell even things about that shit? i couldn't give a more of a shit what a homosexual does in the privacy of his own home. long as a gay person respects me i'll respect them right back, cause that's what Jesus would do.
Asshole, there's 1 million men right now in America paying big money to pass laws to allow men to fuck young children and call it consent.
Is this stupid night or something? Why the fuck would you not care about such a disturbing trend?
Where do you get your news from? Where are these laws being passed? What does it have to do with gay people?
Is there any topic we haven't covered yet? What about fluoridation? Surely there's some angle we can work that into this thread with.
You have any idea how bad fluoride is and idiot doctors actually prescribed it to my kids in pill form.
20 years ago I'd get it but today, with all the massive peer reviewed studies and so many countries in Europe banning it? Are doctors stupid?
You know an interesting fact about that is that besides dropping your IQ and hardening parts of your brain via some weird plaque - this hardening effect, one of the major side effects oddly enough is it inhibits your ability to feel an emotional response towards God or whatever it is you worship.
There's tons of studies out there now about this so it's not even a point arguing about if anyone can read. It's especially harmful to a child's developing brain but like 90% of Americans and even doctors as really stupid and clueless.
There, I hope that's a good enough angle on fluoridation and now I think we have covered every topic on the planet.
Sources please. Also, do you make sure to avoid fluoridated water? It's in all of the water already. How can I trust you if you're already taken over by the fluoridation?

LOL at the bolded part, how is that "when you square a number it still carries the same properties, nothing is lost"? Care to explain that?
From a math point of view that's BS. Two quick examples:
3 is a Fibonacci number; 9 is NOT
3 is a prime number; 9 is NOT
Or maybe we just digressed from math to mysticism? What kind of mysticism? Does the bible says "when you square a number it still carries the same properties, nothing is lost"?

There is some reality behind mysticism but what I'm talking about is hard science - but most don't get it cause you don't start exploring it until you get to classes like Quantum Physics which I never needed - although I did take other lower (200 and 300 level) physics classes.
It gets much more complex than I can explain. I never got farther than calculus but what I'm referring to is true - you're comparing these numbers on the surface. For example it's like saying violet is not red and ignoring all the inherent properties inside that higher and much hotter frequency (violet - the hottest stars are violet not red, yet there is red inside of their physical properties which you cannot easily observe).
With numbers it's much more complex and like I said it gets into really complex Quantum Physics theories. I've read some papers on these theories and I only understand some parts. Enough to comprehend numbers matter more than most people could possibly imagine.
If you're good at math and curious about just how deep simple numbers go just read up on something like the ABC Conjecture. You'd think the simple Linear Algebra equation a + b = c is very straight forward - exactly as you tried to explain. Spend just an hour reading on how deep that goes and how much physics is actually involved and number properties which the human eye cannot see nor fathom and you'll get an idea what I'm referring to.
Coincidentally The ABC Conjecture was just supposedly solved and some think the Genius behind it was non other than Satoshi. So I'm surprised you Bitcoin experts (lecturing me) don't know more about what I've been saying. His (supposedly Satoshi) solution is so complex that not even teams of PhD mathematicians are able to figure out how he did it or what any of it means.
But researching it for yourself (if you took at least stats and calculus) will give you a much deeper meaning in the infinite nature of numbers and how they do carry their properties as you square them, multiply them etc. There are changes within that new number but the fundamental properties of say 7 or 3, they're still existent and functioning in the new number.
Numbers carry real physical properties (as real as gravity) which is something most people don't understand which is why I tried hard to use the "right" numbers.
What sorts of physical properties do numbers have? Do they have mass?
(Also, the theory that Satoshi is the guy who solved the ABC conjecture is just based on the fact they both published their papers online instead of through academic channels. That's it. Not even any links to the cypherpunks. There are tons of better candidates.)
Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency
I'm sure this was answered somewhere already, but what does the chainsperday value represent? Is it the predicted value of how many chains of some specific length will be found in a day? (What length? I hope it's not based on the current difficulty, or else that would mean that you can't use it as a performance metric for comparison at different points in time.)
why so many people discussing but no many people mining?
why ?
why ?
Have you read the thread at all? The thread is hilarious, and the coin is a bad idea badly executed.
No, it will not die, ever.... Unless we find out that there is an end prime, a prime with no larger prime. If such a thing even exists it could take ~100,000 years of technological advancement .
It's easily provable that there is no largest prime, and besides, Primecoin isn't trying to search for the largest prime. It searches for large prime chains.
Once again, of course not premined is better than premined in general, but do you expect a group of highly skilled developers sit and create a new innovative coin (copycat coins are total shit no matter premined or not premined and excluded from my argument) without any profit or return for their work, so the coin get released to the prey of the above-mentioned type of miners who are ready there at the gate to receive, pump-dump and then kill it??!
Uh, yes I do expect developers to make it without a scam. Namecoin, ppcoin, and primecoin didn't have any premine drama. Some people say bitcoin had "premining", but that's mainly just because it took a long time for anyone to even notice bitcoin after it was released.
Incorrect, programmers can be bought from India for /10th the price and or course they'll pay Americsn programmers their $70K, that's not big money.
With programmers, you get what you pay for. (Surely you've learned that very recently!)
To make money you have to understand money not the way the printing press works. That's absurd. You guys are calling me a fool cause I have no idea how Bitcoin's printing press works. I say who gives an F. Can I change it? Does it matter? No. No. So why waste effort end memory space on useless info when I know I'll pick up the idea of it eventually.
You tried to launch your own coin, and you even specified the parameters for how it ought to work. Both of those being attempted by someone without a clue is hilarious.
Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency
song like this scam going to die... but I buy 2 XPM for my colection (after close to full month can't find block...)
It's a scam and dying just because you're failing to mine blocks? I assume Bitcoin is a scam too?
You need to know why things are done. Just like my toothpaste example, you need to know what toothpaste is and what it is for if you're going to found a toothpaste company, and the same is with creating a coin.
That's easy, toothpaste is a ponzi scheme that is going to explode after the toothpaste ETF and everyone is going to want their own tooth paste brand, so we need to get into the market now.
That's absurd. No economics school ever offers a course on how a stock market exchange itself structurally functions. It's absurd. Yet you can go get an MBA and work on a major exchange. This whole idea that i need to understand the actual trading structure of a financial instrument when there's no way for me to change it or alter it is ridiculous.
It doesn't fit with any courses taught for finance or economics. ZERO. You need to understand the theory, the mechanics and what makes an instrument a success and how to value it which in this case it's near to impossible. But how It works, when that is set in stone, who gives an F? That's why banks hire programmers and IT managers and shove them in a room out of the way, cause they do ZERO actual money making for the banks.
I'm not sure how any of that relates to my post, but that last sentence is full of errors. The financial industry pays extremely well for good programmers as far as I've heard. And financial institutions pretty much entirely rely on computers these days, so to say they "do ZERO actual money making for the banks" seems to show a huge lack of understanding. (If that were true, why would banks even hire programmers?)
So GoDaddy charges about $10/yr for domain registration. So you spent $1400 in domains alone? This is absurd.
Yes, and I believe he had mentioned it somewhere before.Hmm, I hold double that for a single online business, it's not uncommon.
Do you mean you own 280 domains for a single online business? If you're in the domain squatting business, I just hope you at least have better taste in names than Vlad.
Re: [ANN] GAS Coin is now dead. r3wt snuck in a premine and scammed the community
I know there are a lot of naive people in the world, but ~$40 to make a client and launch a coin? I know the ONLY way I'd ask that little is if all I had to do was take the existing source code and then search and replace the names and maybe do 1 or 2 tweaks.
Well yeah, did you think Gas Coin was something other than a quick copy job?

Why stop there? This is an unfair world, please disable everyone mining faster than me.
(I love the implication that GPU mining is something that can be "disabled" for the whole network by someone on a whim. Or that it's desirable to do so. Or that it's even happening profitably yet. The difficulty has been dropping over the last few days!)

Re: [XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency
So I discovered the hidden -dedication parameter, and encoded a short message into block 86043 which I mined. I've verified the message is in the blockchain by grepping through the primecoin blockchain files on a few other machines. Is there any proper way to view these messages (such as to check for more in other blocks)? Or do I need to build my own blockchain parser for this?
(EDIT: I tried the linux strings utility. I only see the original block's message, and my own's message. Guess no one else has done this.)
(EDIT2: I tried the strings utility on Bitcoin's blockchain. Doesn't look like stuffing information into a blockchain is that unique of a prank, drat.)

What happened?
I put messages inside two of the blocks I mined. Sunny King's primecoin genesis block and a block by XertoV also had messages in them. You can see them in the blockchain by running "strings -n 16 ~/.primecoin/blocks/blk00000.dat" on a Linux machine for example. (You also get a few lines of gibberish, which I'm not sure if they are intentional.) I don't think there currently exists an easy way to inspect the messages further, such as to find what block they're in.
