I'd like to thank SgtSpike for finding that block.
I shall accept said thanks.  Did you get your BFL's yet? |

I'd like to downsize my mining operations a bit, and am selling one 60GH/s BFL SC Single for 70 BTC. I've had it for about 3 weeks, and it's been mining perfectly. I've been using a computer PSU, as a BFL PSU was not included. PSU is not included in the 70 BTC price, but I can provide one to you if necessary - just PM me to work out the details. Included shipping will be via Priority Mail.

This rash of extreme delays between blocks, both BTC and NMC, seems like it's starting to become a statistical anomaly. A "that-guy-just-won-the-lottery-for-the-5th-time" level anomaly.
Anyone done the math as to the chances of going this long while putting out these CDF numbers? If it continues for much longer, it's going to be a very bad sign.
Until it gets to about 1000%, it's not really that unlikely. When you are finding hundreds of blocks a month, you'll hit really slow ones as well as really quick ones. i.e. at a pool doing 20TH/s, if you get to 22hrs then yeah you are into rare territory for slow block finding. Rare, but not impossible. It's the Namecoin delays that make me suspicious. Namecoin blocks are pretty much solved independently of Bitcoin blocks. So sure, a single long delay, even approaching a day, for a Bitcoin block, or only a few Bitcoin blocks in a couple days, I can understand. But to have no Bitcoin block for that long a period, and simultaneously have multiple long stretches between Namecoin blocks, which hit 50% for us in about an hour? I'm not saying something IS wrong, just that statistically, that adds another level of improbability. Currently... Bitcoin: 12h:09m (97.44% CDF) Namecoin: 3h:39m (91.40% CDF, and that follows 8 blocks where the lowest CDF was 69.65%, average of 83.07%) No need to panic, of course... time will tell if there's a problem or not. But this warrants watching. Are you also going to get concerned about the 2 weeks of above-average block finding we've had just before this 3-day dry stretch? |

Interested in a Windows 8 key... 64-bit? Where/how did you get them?

This looks like it'll make it possible to actually memorize an address. Cool!  It is very possible! I have three of my addresses memorized so that I can easily send to any one of them any time. Problem is, there's no way to look up firstbits right now, and piuk doesn't seem to care that it isn't working on blockchain.info. |

I have the blockchain.info app installed on my Android device, but I am sure that I never created a new address within it and I'm also sure that I never created a transaction on that device. Basically the app only acted as a way to check the wallet balance and transaction history (i.e. read-only actions).
Are my private keys and transactions at risk if I don't do a key rotation? With the many small and non-mature inputs I have on my many addresses, I am heading for maybe over 0.02 btc for transaction fees... last time I did a key sweep it was something like 0.01 btc, and to be honest I think my wallet is even more fragmented now.
I don't think the app ever had any reason to request random numbers unless it is creating addresses without user intervention.
On a related thought: many online wallets generate private keys client side with JavaScript. How secure is the PRNG used by JS, or is it not used in a direct way (are there other sources of entropy)?
My understanding is that if you sent Bitcoins from any of the addresses in your blockchain.info wallet more than once, it could reveal the private key of said addresses to anyone clever enough looking at the blockchain. If you didn't generate any addresses or send any Bitcoins from it, then you should be fine. |

Bitminter is about 20TH. Network is 400TH. 400 / 20 = 20. Therefore Bitminter has a 1/20 chance of finding a block. Statistically, BM should find 5% of 124, or about 6.2 Blocks/Day (currently).
Isn't it 144 blocks/day (at 6 per hour)? I calculated it differently. 20 TH/s at the current difficulty calculates out to 268 BTC/day using this web calculator: http://www.alloscomp.com/bitcoin/calculatorTherefore, we should be finding, on average, 10-11 blocks per day. |

There was a minirig for sale for $50,000 on the forum here... I'd buy that.
I'd buy from Bitfury and HorseRider if I had 50k. HorseRider is selling 100+ Ghash/second units for 100 btc and shipping right now. Bitfury...well I already ordered 5 units. I'd put some Money in btc when it hits $50-75/btc price. Bitfury I don't really trust. HorseRider is selling less efficient units at the same price/GHash. The minirig for sale on the forum would also ship now. |

It was AVG, had to uninstall it sadly.
Thanks guys!
Do I have to do anything to start using it or do I just press start and log in?
Also, what rates are average for a decent laptop? I'm getting ~350KHPS with 4 of 8 cores.
I'm getting 60,000,000 KHPS with one dedicated Bitcoin miner. In other words, it's not worth it to run on your laptop. But, it is fine to use to play around with and get to know how Bitcoin mining works...! You will make 0.0002 BTC per month mining 24/7 at that rate. |

Do you have AVG antivirus? If so, disable or uninstall it, and use something else. I had trouble starting up BitMinter when AVG was enabled, and other people have reported the same.

Ummm.... correlation, please.
The reason that the hashrate is going up like it is and that difficulty is about to make its biggest jump ever is because of BFL units hitting the market.
I know that's what they're telling their forum members, but you've seen the pictures of hundreds of thousands of Avalon chips sitting in boxes, right? Millions of them have been made and it's unlikely they're all sitting in customs. Additionally, Bitfury chips have also started shipping. Some of the network growth is BFL. But claiming that it's ALL BFL is completely wishful thinking on the part of BFL users. Yea, BFL users must be living under a rock if they believe the diff increase is primarily due to BFL. Sure they take part but give me a break. Look around, there are other ASIC companies releasing chips and units at a much higher rate than the public BFL information. Sure, BFL could be mining the crap out of the network but that is not due to the ones they have shipped. Who? Who else is shipping all these TH/s of devices? BitMinter has grown from ~8 TH/s to 19 TH/s in a matter of a few weeks. A large number of top players in that pool are running BFL machinery. WhitePhantom, cloudhashing, fefox, mralbi, fpga1, SgtSpike, forabit... and those are just the names I recognize. The top 50 could all be running on BFL miners for all I know - ask them, if you want! But certainly, if there are other companies releasing chips and units at a much higher rate than BFL, then why do we not see users running those other company's miners at the top of the list? Why are all the top users at BitMinter running BFL machines? Everyone loves to bash on BFL without any proof to back it up. |

Could the OP be updated to include a list of apps that have been updated against this bug? I don't want to read through the whole 8 pages to find out which apps have and have not been updated, and I'm sure it'd be helpful to other people as well.

Hey, I actually finally found a block! Yay me!
was it you who broke our 6-hour drought?  I just joined the pool yesterday after plugging in my 4 module Batch 3 Avalon... let's mint some coins. d No, but I broke a 3hr 33min drought. It was about 22 hrs ago. |

I'd put wifi packet sniffing as the culprit at a very low possibility.
But how was his email compromised originally? That's the point I was trying to make. While he was at another location, he was likely asked to re-sign into his Gmail account. It could be at that point the password would have been sniffed through some form of MITM attack. Later on, the hacker would just sign into the compromised account, read the emails he sent to himself with all the details, then take the coin using any of those other alternatives. I guess what I'm trying to do is not just gloss-over the "gmail was compromised" part. Phishing or malware seems more likely, but you're right. I consider wifi to be unlikely because you're assuming that: - OP visited a compromised wifi - OP logged in to his email using a compromised wifi and not using https - Attacker knows about Bitcoin If the attacker's purpose was to steal Bitcoins, he'd be much more likely to do it by targeting people he knows use Bitcoin. Targeting random passerbys as they utilize the wifi would mean he'd probably have to search through thousands of email accounts before finding a single one that has a blockchain.info account, much less one who stores a significant amount in BTC. By targeting, say, the MtGox list of email addresses with a phishing email, he'd be likely to get access to dozens of emails, all owned by people who use (or have used) BTC. |

Thanks for the clarification. However, would this sort of attack still trigger Blockchain to send me the SMS code like they did 3 minutes before funds were transfered.
I'll make some assumptions here. Specifically: - You had a backup of your wallet sent to your email account.
- You had your identifier sent to your email account.
- You had your password sent to your email account.
- The thief has access to everything all of the above
- The thief knew how to avoid being identified
Given those assumptions, when the thief saw the identifier and password, they may have tried just logging into your blockchain.info account rather than mess with the backup. When they discovered that you have 2FA (which would trigger the SMS code to you), they could move on to the backup from your email. Once they have the backup, they no longer need 2FA. They can use the information in the backup to send the bitcoins without ever accessing your account on blockchain.info. Assuming the thief was intelligent, they would use a proxy (perhaps TOR?), so the IP address you have would be a proxy exit, and not the IP of the thief themselves. This sounds like, by far, the likely course of action by the thief. All they need to do is compromise your email address, and they have all the information they need right there. And email addresses are compromised all the time, for a variety of reasons. I'd put wifi packet sniffing as the culprit at a very low possibility. |

http://bflfraud.com/The text does not lie. The Skype chat does not lie. The images do not lie. VERBUM SAT SAPIENTI EST!* *A Latin phrase meaning: "A word to the wise is sufficient!" I dont have the time to read all that. What is the smoking gun two sentence exec summary? Right here: Essentially what went down in this deal is that Cloudhashing had managed to get a BFL 1500 G/hs Minirig removed from the delivery queue and needed someone to verify its existence and quality before sending an amount someplace in the area of $100,000.00 to BFL for the purchase. If this is true, and BFL is allowing people to skip the queue by paying more, without making this a published option for purchase, then I completely agree this is fraud. |

Why are some addresses harder to find than others when you change only 1 characters case. For example at the vanitypool there's work for a 1bitpoin, and my computer says it will find one for it in ~10 days, but when I search for 1Bitpoin it can find it in 5 minutes...?
The answer is exactly two pages back (again). That's called dedication to not looking for the answer before asking... How could he have known that without reading 70 pages of posts? |
