My man  Do you read seoblackhat.com or did you just stumble across that post!? Quadszilla used to be a God to me. Until he stopped posting about 2 years ago. Yes, it is still relevant. Thousands of websites still use Alexa data and consider it useful. Yes toolbars are a scam meant to watch where you are going online, but alexa only wants to do that, and nothing else, so they can determine which websites are the most popular. Fairly innocent imho. Also it is quite easy to remove from any browser. Download & install the toolbar. Capture the traffic (with tcpdump, Wireshark,...). Uninstall the Toolbar. Write a script to send automated requests to Alexa featuring Bitcoin-related sites  Although it used to be possible, I am afraid it is not anymore. I am pretty sure I did this about 6 years ago. Or used somebody elses working script. Today however, I am 99% sure they use nonces in every url call and salted hashes to verify them. I was looking at their API calls just the other day through firefox's "live http headers" extension. |

As it stands - with my visa credit card and/or bank checking account... if a hacker/virus happens to "steal my identity" and then make fraudulent charges towards my account... the bank will pay me back.
Actually, bitcoin pretty much solves this problem. The reason there's so much fraud is because there is no private key with credit cards, bank accounts, etc. Whenever you use your credit card, anyone can take that number and use it again as much as they want. With bitcoin, I can make a payment to anyone, and no one will ever be able to use that address to take anything from me. Here, I'll show you. Here's my bitcoin address 1H8KtBi9tFtD2vKhNaY9NV5Tbe4rLm4267. Now you post your credit card number and let's see what happens. Either you didn't get my original question, or you created a straw man argument out of it. I'm talking about what happens when somebody's password is "phished" from an online bitcoin bank, and all of their money "withdrawn/stolen/etc"... As it stands, if am stupid enough to enter my username and password into a webpage that LOOKS LIKE my banks... as much money as possible will be withdrawn in as short as time as possible before they account is closed or the perpetrators caught. I'm just saying the idea that there will be free bitcoin banks out there charging 0% or next to 0% in fees is a fairy tale. Banks will always need to take in large amounts of money as a form of insurance against phishing/theft/fraud which are all possibilities when you use a central banking website. No matter what format you keep your money in, somebody will figure out a way to take it from you. |

We already have witcoin, this seems like exactly the same thing without the tiny fees.
Except for the tiny fact that stackexchange is already known, trusted and loved by millions of computer programmers. Plus it has an interface specifically designed for the task, such as badges and scoring that help new users immediately identify who knows what they're talking about. Actually, it wouldn't be a bad idea to have an official badge on the forums for "one of the core developers verifies that this person actually understands bitcoin", and maybe people's OTC web of trust rating. Exactly. I have always thought that even adding a "thanks" button to this forum would increase the ease with which I could read through this forum. Lots of trolls on here just saying whatever comes to mind. |

Is the network hash rate just an estimate?
Yes, and a very tough one to make. Ok thank god. I thought I was going nuts there for a second. I'm a man of logic. And the speed with which that number sways every few hours doesn't make sense given the nature of mining. |

Imagine Google can summon 5.4 TH/s of power. The current hashrate is .6 TH/s. For the sake of simplicity let's say difficulty adjusts every 2000 blocks.
Blocks 1-10000: Business as usual; network ends at .6 TH/s.
Block 10001: Difficulty resets. Google turns on their network; starts hashing.
Blocks 10001-12000: Google finds these blocks approximately 10 times faster than they should, or, approximately one per minute.
Block 12001: Difficulty spikes to approximately 10 times the last difficulty. Google shuts off their network; hashrates are now .6 TH/s again.
Block 12001-14000: The network finds these blocks approximately 10 times slower than they should; or, approximately, one block per hour. Instead of taking two weeks, the next difficulty reset takes five months.
Except that can't work. As I mentioned earlier, there is a difficulty adjustment parameter rule that prohibits the difficulty from adjusting up or down by more than a factor of four. So the max that can be expected is that the Google can do is move the difficulty by that factor of four, which may or may not actually be worthwhile, but if the attack cannot be repeated in consecutive cycles (maybe, but I would say that it would be very unlikely to work out that way) then it's probably not a worthwhile means of manipulation for profit motives alone. What kind of harm to the system itself could such an attack cause? If someone had access to 100 tera hashes per second... they could user 10 for the first 2016 blocks, 25 for the next, 50 for the next, and 100 for the next 2016 blocks... and then leave... placing us in a predicament that takes more than a few hours to allow a transaction through the network... |

Agreed. Creating our own stackexchange is crucial to our survival.
It's truly a great system. I use it regularly. Will sign up right now!

Wasn't Bitcoin created in big part to resist governament, big banks etc conspiracies?
That's what they want you to think, remember, just because you're paranoid, doesn't mean they're not after you. Trololololol |

Click here to download the alexa toolbar.It's easy to remove and will make bitcoin.org look like a behemoth of an online community if all of us install it! Which will lead to more press because the site will look more credible/etc..

The one I know of is the one that generated a few billion coins. That was a bug in the client, and the block was invalidated.
Can you expand on this? The one I am looking at is at the bottom of blockexplorer.com currently. It claims that 3 blocks all had different hash values and slightly different (albeit very low) number of BTC sent... What happened there? |

As seen in the top all black nav bar of http://bitcoincharts.com/markets/How do they determine the number of terahashes/second, currently at 0.735 Thash/s Isn't a hash only submit to the network once it has been deemed to be below the target value? Is the network hash rate just an estimate? |

Just saying, if you had bought bitcoins on Mt. Gox at 11 o-clock today and sold it now you would have made 10 cents per bitcoin. almost 20% gain for a 6 hour investment.
Try doing that with anything more than $1,000 though and you would probably lose money. |

Can Somebody Explain The "Strange Blocks" Found On BlockExplorer.com?

Good stuff. I didn't vote (because I did not contribute) - but I believe the video portrayed the message beautifully. I showed it to my somewhat tech savvy mother, and 3 of my friends, and they all "got it" by the end of the video. I say this is a job well done. Kudos to the creator of the bounty and the video. |

I'm not really familiar with the system yet, but do have a lot of questions running around in my head.
So, starting with this. Is there any way to estimate the possible ecological impact of people using their computers to calculate BitCoin cryptography? Is the actual processing power - and therefore the amount of energy - spent to calculate a particular amount of BitCoin currency the same regardless of the number of users in the system?
I'm not really sure whether or not this is a really stupid question, but, well... I presume other people have been wondering about it as well.
edit: btw, is there any way to get an email notification for new answers to a topic?
A good Mhash/watt ratio when mining is > 1.5... You mean < 1.5... don't you? God damn you write novels almost every post  Makes me look like a lightweight! |

...The power to withold my custom from providers I disaprove of, is extremely important to me.
Am I alone here?
No. Not at all. I (and the rest of north america) would instantly refuse (without question) to help fund any group labeled as a "terrorist". |

Today bitcoind locked up on my server and wasn't responding to errors.
Apart from saying 'bitcoin shouldn't crash', what kind of backup systems could exist to gracefully recover when Bitcoin locks up?
Not sure what can be done except calling an safety check hook which kills/restarts bitcoind. Ideally it'd be nice to run multiple nodes and switch between them freely (sharing the same wallets or having 'backup' nodes with a BTC store).
Are you OCing your CPU and/or GPU? If so, by what percentage? And what CPU/GPU? |
