In deiner Wallet sind Zugriffsschlüssel gespeichert, nicht Bitcoins selbst.
Stell dir das wie Bankschließfächer vor - wenn du den Schlüssel verlierst, dann kommst du nicht mehr an die Bitcoins im Fach. Genauso kannst du deinen Schlüssel kopieren wie du willst, das Schließfach wird sich deswegen nicht verändern.

https://en.bitcoin.it/wiki/DifficultyThe difficulty is set such that the previous 2016 blocks would have been found at the rate of one every 10 minutes, so we were calculating (D * 2**48 / 0xffff) hashes in 600 seconds. That means the hash rate of the network was
D * 2**48 / 0xffff / 600
over the previous 2016 blocks. Can be further simplified to
D * 2**32 / 600
without much loss of accuracy.
That's what I meant - your numbers are off. Slightly off, but still, they are wrong. Considering that ASICs do cost (and hash) different magnitudes than CPUs back when this Wiki was written, this can amount to more than just a few fractions of a cent over time. Correct is: (2^48/65536) instead of 2^32 What might be helpful too is to help people come up with their real energy costs: I pay less than 10 EURcents per kWh for the energy itself, but that's only about a third of the actual price I pay (the other thirds are roughly: network fees like maintenance and so on as well as taxes for subsidizing green energy + the 20% flat tax). What might help is to let people enter the following data from their last electricity bill: "My last electricity bill total kWh used" "My last electricity bill total amount of currency paid" From that you can calculate the real costs (including taxes, fees, fixed costs and whatnot) of electricity for a user, which probably should serve as an upper bound (though some companies seem to charge more per kWh if you use more to incentivize saving) but at least as a more realistic projection than some numbers you might find on a web site of an electricity provider.

...besonders wenn die Konkurrenten von Facebook sind. OAuth (also Login mit Google/Facebook/...?) an sich finde ich sogar eher gut, da muss ich mir wenigstens nicht Gedanken drum machen, ob die ihre Passwörter verschlüsseln oder nicht. Interessant finde ich, dass die jetzt ihre eigene "Währung" pushen wollen: Zen Übersicht der Infrastruktur: http://www.zurker.eu/update-1-139Irgendwie komplett lächerlich in meinen Augen, da kann ich ja gleich PayPal verwenden! Entweder dezentralisiert (Bitcoin, eventuell in Zukunft Ripple) und losgelöst von Fiat oder rein Fiat. Die wollen da irgendwie ein zentralisiertes Mittelding ala LibertyReserve mit einer Korbwährung aufbauen - wie das in der Ralität aussieht, sieht man ja an LR. |

An easy "100 MH/s raw return per day at current prices + difficulty" with ~10-60 minute resolution would be nice.
Also please list the formulas you use when calculating your stuff, quite a few "mining calculators" are inaccurate.

Why use the exponent and not just the hash as passphrase?
Anyways, the resulting address is not usable for anything besides transferiing something there once and transferring it off again immediately, then forgetting it. Since commit-hashes are public information, these are far too insecure to use the resulting private key for anything else than timestamping.

Are you limiting this to amazon.com or do you also want to operate on amazon.de and amazon.co.uk?

" up to 27.25%" - what's the average return? Also, how often do loans default? This rate would be the equivalent to the risk of PMBs going down in value over time. Anyways, I'm definitely not going to bet on PMBs returning close to 30% APR...  Interesting and straightforward bet though. Might not be the right forum for that though? |

Hm, maybe a differently worded question: Which kind of games shall this business produce? Gambling aka. games of luck? Games based on skill? Feeding alpacas on your little farm with carrots that you bought for Bitcoins in a microtransaction and posting every fart of said animals on Facebook, Twitter, Google+, Diaspora, the hidden wiki and Bitmessage?
Games can reach from board games to the movie "Saw" or analyzing stock markets, so I would really like to see at least a bit more specifics, even if the business doesn't exist yet. I guess at least the idea for said business exists after all and I suspect/hope it is more concrete than "let's do something with games - first let's collect at least 1k BTC and then let's see what we do with it!"...
Just as a benchmark: Anyone raising more than 100k EUR in my country has to publish a prospectus (which is causing quite a few discussions atm. as businesses want to collect money without telling their investors what's going to happen with it) - your IPO is for ~1 million EUR and will even be considered failed if you "only" raise 100k EUR in BTC. Outlining the business plan and idea a bit more concretely is something that can be expected for these sums I guess.

"Game" can mean a lot - are there already some products in the pipepline that you can talk about?

Maybe take a look into the suggested payment standard from gavin iirc.

As far as I understand it, "anti-launderers" can only "un-mix" as many transactions as they themselves have initiated. To uncooperative launderers that doesn't change anything, they would only increase the volume, which might lead to more customers, both reporting and non-reporting ones...
In your example, 5 inputs (2 unknown, 3 known ones) lead to 5 outputs (in reality probably 6 (--> operator's cut) or even more (--> splitting into more smaller outputs)) of which again 3 are known and 2 unknown.
I don't really see the point other than you paying fees and maybe being able to find out an algorithm behind the outputs (though I guess that can be circumvented if the laundry operator is using enough randomness) - you have the same situation as with only 2 unknown inputs and 2 unknown outputs.
It is a problem with coin laundries though that there is no clear idea who the other participants are - if you can not be convinced that these are not in fact a single entity or (worse) multiple colluding entities as you suggest, there's a problem. The "best" way to launder coins is still buying mining capacity at slightly above returns and request that coins be mined to one of your addresses. This way you'll get vanilla coins that should be untraceable. If you feel risky, you could even spend dirty coins as fee to be mined, but if your miner hits a fork/stale block just at theat moment, you're potentially screwed as other miners then would take this juicy transaction from that block and mine it themselves.

Hello Sukrim, Things I want to see as lender:
Higher leverage of at least 1:5 on the internal exchange at least
Margin trade for ltc to make them borrow more money. I need to ask you something for this: are you ready to take a loss as a lender if there is not enough liquidity to liquidate a position before a trader's balance is negative? This is actually the biggest problem. April has shown us that when the market is volatile, bad things can happen. At the moment we have chosen the path of the safety, first to recover from April losses, secondly until we are sure of the risk appetite of lenders. Actually yes, as there is an insurance fund in place to cover for this. At the current rates I get for my loans (if at all) I rather have my money at my own bank than somewhere in HongKong, Slovenia or Japan. Higher lending interests would change this. Anyways I'm not suggesting you to let your traders run loose with huge margins, but I guess you can do better than 1:2.5. If you're so afraid of external factors, let them trade high margins only on the internal exchange. Also you can limit external exposure (e.g. MtGox) by just trading a couple thousand USD there and not potentially unlimited funds. Then withdraw these and as soon as they are credited on your bank account, rinse and repeat. (P.S. I hope you keep your Ruby runtime up-to-date, there are exploits roaming the net again...) If you are worried about volume, make sure you actually report it outside of bitfinex, e.g. on cryptocoincharts.info. nobody actually knows that you can also trade altcoins on your platform.
Also report your depth and volume to bitcoincharts to get more ppl interested who might also want to margin trade. Yep, will do. Fix the rounding issues, at least (!) in the history tab - my ledger is already about 0.0004 btc off from the account balance. If you calculate with 8 places precision, report somewhere with 8 places precision! Ok we'll show you full precision in history table  Thanks, much appreciated! If possible, a download in csv format for example would be great, I don't want to write html parsers...  |

As a lender it starts to get annoying: every time you announce a new feature, you announce it either only for traders or that it will be bad for lenders or you don't announce it at all, like indefinite halting of trading on mt gox.
That giancarlo is taking a lot of comments quite personally and seems to respond typically in a relatively defending and to me borderline insultive way (not quite mpoe-pr yet though) doesn't help either.

Finally: if you change something serious, like completely stopping trading on one exchange, decreasing leverage or increasing lender fees again (not half a year ago they were below 2%...) if it is not 100% threatening your whole business, allow for some limits or time to pass until this comes into effect.
I'm sure traders would have been much happier if they were allowed to trade 5k USD every day or until these 5k USD are back on your account from gox to limit your exposal to them. Having only 100% exposal or nothing at all is in my opinion (and as it seems like also in the opinion of traders if you look at the volumes borrowed) not a very good choice.

Also aus Wien hab ich noch nix gehört, ansonsten hat's ziemlich alles an der Donau und den Zuflüssen mal ordentlich durchgespült... Laut ORF scheint Wien auch recht gut gegen solche Hochwässer gewappnet zu sein: http://wien.orf.at/news/stories/2586912/ |

Mining bonds don't even have to be backed by mining at all, they are just dependent on difficulty.
Yes, it is good for the issuer (if he actually does mine) to have cheap electricity, but this doesn't influence the payout of the bond at all.

Repeating what I said (both XRP and BTC can be inflated, BTC risks loosing their miners, Opencoin risks loosing their customer base, both risk loosing trust which is the only thing that keeps both currencies afloat) and re-formatting it in bold doesn't change much.
I'll just ignore the ad-hominem attacks, also if you feel that my posts are stupid or that I lie about working for Opencoin (hm, actually I could contact them if people already think I do work for them...?) you're free to press that ignore button to the left of this post, kthxbye.
Back on topic:
I wonder why there are still so few highly trusted entities for cryptocurrency IOUs in Ripple, the ones I know of are:
TradeFortress(lol!)
Bitstamp
WeExchange (who think of removing Ripple functionality for some time/indefinitely until the server runs more stable)
DividendRippler
That's more or less all I know of, which is a little bit little so to say...
Where are actually the issues besides being trusted by the community when setting up a cryptocoin IOU gateway? Do you absolutely need a server? Is it too hard to code a client for this?
Cryptocurrencies should actually be one of the easiest things to get into Ripple, as there are probably also fewer regulations around them. Why are there so few gateways then? (yes, I know that there will be a handful of "hero members" who will now post again that's clear "because it is a scam"... if you think that there are other reasons besides that, please post them too)

Is funny that in 2013 a government wants to ban alcohol  ... or wants to have warrantless access to anyone's data because of ... ... ... ... ah, well, let's call it national security! |

On Ripple itself, it is after all an IOU exchange/market place.
