Buy on blockchain? You can not buy anything on blockchain, are you maybe thinking blockchain.info which can show you the price in USD? Its in the lower right corner.

Wo man am meisten mit BTC zahlt glaub Silkroad oder wo anders ?
Ich geh mal davon aus das Du am häufigsten meinst... Vermutlich Dell, dieser Amazon Gutschein Service (effektiv: mit BTC bei Amazon zahlen) oder bitpay bzw. der andere ähnlich Dienst auf dessen Namen ich grad nicht kommt. |

CoinPiler is full for below Senior
Do you think you should move primedice to closed for new participants (maybe with an asterisk) as they are only accepting staff and legendary members. Alternatively you could keep it as "open" and asterisk it with the same.
I won't change it, because some people cannot join anymore. Haven't done that in the past, won't do it in the future. It's too much work to keep track of all campaigns and change it if a certain rang cannot join anymore. |

Where to begin.....
Lets start with your own math, You say that list is complete and made on the fly, the last page of it has been xxxxxxxxwhatever ending in 75 for a long time now. with 128 keys per page, when calculated to the total number of valid private keys, it barley scratches a few percent.
You are indeed correct, its only 1.15*10 34 of 1.46*10 48 possible keys. I didnt check that. If in fact it were a complete list, then the host of that website would have to have had to invent the worlds largest, and most super efficient hard drive to ever exist, forget the multiplier. 10 to the 25th power YoBiByte's of storage is about 2 to the 118th power more storage than exists on this planet as of january of this year the entire worlds stored data was around 6.8 zettabytes.
Yes, that was the point. Not enough space to store the list, thus impossible to search. Btw each page there is ~60KB in size, with 904625697166532776746648320380374280100293470930272690489102837043110636675 pages thats 5.42*10 33 bytes or ~4.7*10 15 YiB as you allready said yourself thats more than currently is available worldwide. To finish your reply, i guess you missed the HUGE RED FONT where i said this was all a hypothetical and where i also pointed out that "it wont work" which pretty much falls right in line with " its not possible " is an implied state in this scenario
Hence my: "I know you dont want to hear "not possible"," Anyway, Ill leave your thread to you, enjoy your butthurt. |

HUH? TL;
and of all of that i didnt see a single reply to the question.
tl;dr : you ask the wrong questions. To verify "ownership" (does not exist in a physical sense) of an address you need the private key that belongs to it, so this imaginary database is useless. I know you dont want to hear "not possible", but what else is there to say if there is no other way? -snip-
Well first off, that is far from a complete list, if even 5% of every bitcoin address out there.
It is complete, its just not a database. Second, it is not indexed to be searchable,
No because that would require an actual database in the background where all the keys are stored. Its generated on the fly. 2 160 possible different private keys, each needs 32 bytes, so "just" ~4.676 * 10 49 bytes or ~3.868 * 10 25 YoBiByte. |

Just simply put, if you post at least 1 post every 14 days you'll get 14 activity, if you post 1 time in 2 periods (28 days) you'll still get 14 activity and not 28 so you must post 1 post every 14 days to get your activity. It doesn't matter when you post in that period, you can post at the end of the period and next day at the beginning for the new period and you'll still get 28 activity for 2 periods.
You get 14 "time" which in turn is used when activity is calculated, but the number of posts is still a cap on your activity. Thus 1 post in 14 days will result in 1 activity unless you previously had # posts > activity. |

But that link doesn't show post timings at different activity levels?
Please elaborate.
read the faq https://bitcointalk.org/index.php?topic=703657.0read the followup links The thing is the same question gets asked 5 times a week and the most you can expect now is a link. |

anständiges Miningtool z.B. ?
Hab eins von Bitminter .
Is das nich n pool? Wenn die ne eigene Software anbieten probiers aus, hatte eher an CGMiner bzw. BFGMiner gedacht. |

|

naja nun , aber zurück zu meiner frage bitte .
ausserdem verbraucht meiner so etwa 1,2 watt^^
Stromverbrauch: 2,95W bei 2GH/s
http://www.amazon.de/gp/product/B00IRKMO90Wie hastn das gemacht? Aber ist eigentlich auch egal. Selbst wenn Du von ~0,875 Watt ausgehst (ca. 1/4 von dem was ich angenommen hab) machst Du 0,015 € / Tag bis zur nächsten Difficulty Steigerung. Danach musst Du dann noch n Dummen finden der dir das Ding abnimmt damit sich das gelohnt hat. Ich weiß nicht. Alleine der Aufwand an Zeit. Einfach mal ne Überstunde schieben (wahlweise 10€ weniger rauchen/saufen/Süßigkeiten kaufen) und BTC von kaufen, da machste zur Zeit mehr Profit mit. Ich geh davon aus das der Kurs weiter steigt nach dem Tief grad. Dein Profit von minen ist ja eh abhängig vom Kurs. Ansonsten, ja kannste zusammen betreiben sind beides USB Sticks, anständige Miningtools kommen damit problemlos klar. Der eine macht halt nur 330MH/s ~ 0.33Gh/s der andere 2GH/s. Der Blockerupter ist die erste Generation ASIC soweit ich weiß. |

If you report the PM the mods can verify if you indeed got that PM or not.

klar wirft der etwas ab ein 2 gh/s miner ca. 0,02 €/Tag wenn er 24h/Tag läuft.
Hast Du mehr als 1,50 € dafür bezahlt bekommst Du das geld nie wieder zurück.
Bis zur nächsten Steigerung der Difficulty  Sicher hab ich mehr ausgegeben . Und das geld bekomm ich spätestens am verkauftstag zurück Nein, Du zahlst Stromkosten für das kleine Ding, glaub so 3,5 Watt brauchen die. Das sind bei 20cent/kwh genau 0,02 € / Tag[1]. Lustig, bringt genau 0 gerade Naja vielleicht sind noch ein paar µCent drin. Wenn Dich das interessiert dann hau rein, wenn Du damit Geld verdienen willst, vergiss es.

No i whant to split them so if i get hacked the lost of coins is not so big!
You want to keep your wallets split so its harder to hack you, but still keep them all on your phone? I'm guessing he wants to be able to control all wallets at the same time on his phone. Are you using the blockchain.info app? Yes, I know, but that does not make it any harder to get access to the wallets. They are all on the same phone, thus if the phone is corrupted, all wallets are corrupted. |

Danke für deine Hilfe  ...ich hab eben einen Mac Computer ...das komische ist ich wollte 0.001 an eine Adresse senden Dan in der gleichen Sekunde war alles weg und hat alles bis auf den letzten sathoci alles abgebucht ....geht normal gar nicht ...sehr sehr komisch ... In dem Moment wo Du Deine Wallet entsperrst hat ein Trojaner drauf Zugriff und kann eine Transaktion fertig machen. Die muss dann natürlich noch bestätigt werden, aber das lässt sich in der Regel eh nicht aufhalten. |

Does anyone know how I can achieve this? briefly had a look through blockchain but not sure where to start...
Its not possible for wallets*, but for addresses. I made a little java tool [1] a while back (sadly for an idiot, but maybe it can help you) that takes a list of addresses, checks blockchain.info's API for the balance and writes it into a file. You could use that to get the balances for each of your addresses and make a sum of the result to know how much BTC is in your wallet. But honestly, why does your wallet client not show the amount of BTC you have? *wallets do not exist on a protocol level, but are an abstraction to help humans handle multiple addresses and keys.

Did everything! -reindex a couple of times, replaced the wallet.dat with a backup and then rescanned! But nothing  The coins are probably lost forever! Wasn't a big amount but it is a big question mark on the software! Hopefully someone here will be able to tell me what really happened! Did you dump the private keys and reimported them into a new wallet? |

Danke für die rasche andwort ..multibit mit Passwort ..aber wie kann man das so einfach stehlen ? BTC sind doch normaler weiße sicher nicht ? Nein wieso sollten sie es sein? Kryptographie schützt leider nicht vor Unwissen. Wenn du einen Keylogger auf deinem PC hattest, könnte der Dieb dein Passwort wissen und dein Wallet leer räumen. Bei Multibit mit Passwort würd ich auch von nem Trojaner ausgehen. Am besten System runterfahren und von extern scannen z.B. mit desinfec't [1]. [1] http://www.heise.de/download/desinfect.html |

Any ideas?
Since they are aware of the problem Id say wait. What else is there to do? |
|

Thanks for your ideas So first I have to tell you I'm an economics student and really not a programmer. I'm very excited about a financial system that is built on an algorithm, instead of the reputation of certain institutions. However I'm rather new to the actual mechanisms of the trasnactions. So with bitcoin @ 500 USD/BTC you are talking about 2mBTC to 10 mBTC Id think the fee of 0.1mBTC could be a problem as its 1-5% of the coins transfered each time and you also want to profit. How would you solve this? So when I want to do a small transaction, I have to pay extra miner fees? Do I understand it right, that the system is designed to give miner incentives to confirm bigger transactions first and to rather avoid small (or spam) transactions? The fee is not determined by the size of the TX in value but by the size of the TX in bytes. A TX is made off at least one input and at least one output. Each input and output need space and the miners fee that is currenly considered appropriate (by the miners!*) is 0.0001 BTC per started KByte. So every TX would have at least 0.1mBTC in fees if you want it to confirm fast. The way I understand your idea, the moment you broadcast the TX you want it to be in the next block. To ensure this you would have to pay the above fee. But since you also want to transfer very little value in comparison to the fee a very big part of the transfered value would go to you and the miners. In short: it makes your service very expensive. Microtransactions are currently a bit problematic with bitcoin because of the way to fee works. To avoid spam there is a limit how big an output can be, its ~5432 satoshi. That way its not possible to send spam TX worth 1 satoshi each. Can I see somewhere what's the likelyhood that a transaction is confirmed very fast, with a given miner fee and the assumption of profit maximizing miners, based on empirical results?
Blockchain.info shows a "priority" for each TX, but thats often not correct. I usually have very fast confirmations (within the next block) when paying 0.1mBTC fee, yet there have been some posts recently that took a while even though they paid an appropriate fee. There is also the factor of aged coins [2] which gives older inputs a higher priority. Here is a strange one: https://bitcointalk.org/index.php?topic=741046.0and here is one that had no fee and took 1 day: https://bitcointalk.org/index.php?topic=741152.0There is also this statistic [3] that shows the average time for a confirmation, but I dont know if there is something like that for mean times and for TX without/with low fees. How can you time in advance when the TX will be confirmed? Or could your customer only determine when the TX will be broadcasted? They could determine when the TX will be broadcasted. Is it possible to guarantee that for example in 95% of the time the TX will be confirmed within the next hour? This would lower the uncertainty for the customer. The way the network is designed the average time for the next block (and thus the first confirmation) would be 10 minutes. Again blockchain.info [1] (as well as other block explorers) have plenty of data on that. Since you are apprently looking for a high TX volume, maybe you can make a deal with one of the pools to include your TX even with a lower/no fee. Blocknotify and walletnotify are features of the bitcoin-core client. If you set them up the bitcoin-core client will notify (hence the name) another programm that a new block (blocknotify) or transactions for one of the wallets addresses (walletnotify) has been noticed. This other programm would be started and handed over data to know which is the new block/tx. Since this can happen very oftern and bitcoin core will start a new programm every time, it makes sense to keep this programm very small and fast. You can use this to feed a database of sorts or any other tool that you use in the background that is not actually the wallet itself. It can also be used to resend incomming transactions to a central cold wallet once a certain amount has been reached. Not actually little child level, but I hope it still helps Make the payment arrive at cold storrage and since you have a timetable when you need to send coins you can manually fill a hot wallet that automatically handles the timed TX from you to the destiny. E.g. do not allow times less than 8 hours in advance so you know how much you need in the hot wallet for the next 8 hours and can fill it in 3 shifts each day. That makes sense thank you! * There are discussions whether the fee is currenly way to high and should be a tenth of that, but it is very hard to force miners to change that policy. Mining is securing the network and its expensive, so its hard to blame miners for greedy fee practices.

First the dumbass tries to blackmail a gambling business, and then when he's called out on it he tries to punish me with negative feedback.
This guy's about as trustworthy as Kenneth Lay and Jeffrey Skilling. I'd trust Bernard Madoff with my money before I'd trust Timmy with even a penny.
Yes, but its not like its going to make a difference is it?  |
