At some point there will be some instances where the escrow partners will need to perform dispute resolution. Like right now, I'ld be hard pressed to know how using escrow would help a seller where the buyer makes a false claim (e.g., the buyer claims the box that arrived had a brick in it instead of the expensive item the seller had shipped out.) How does the escrow know if the seller is not lying, or if the buyer is not lying, or both are not lying as in the scenario where the box did indeed come with only a brick, but someone at the package delivery service was responsible for the switch. Heh, or this situation -- FedEx says it was delivered. Buyer says it wasn't: - http://www.digitaltrends.com/apple/ups-man-steals-ipad-miniWe know how PayPal deals with it (the seller is presumed to be guilty unless the seller has done hundreds of transactions and does not have a history of getting customer complaints). - http://codenerdz.com/blog/2012/12/05/post-mortem-outcry-of-the-crowdAs bitcoins start to be used for transactions involving higher dollar amounts, I can see there being the need for an escrow partner who is local and will provide the personal services sometimes necessary with certain types of transactions. For instance, if the escrow partner personally inspects the shipment and the terms are FOB origin, for instance, the seller can be paid before waiting for the items to reach the buyer. Or the escrow partner meets with the domain name seller and observes the transfer real-time to ensure it was assigned properly. Or maybe provide additional services as well (e.g., visiting the seller to pick up the item because the buyer will be traveling to complete the transaction and won't arrive until after business hours.) I came to this realization that this really is the essense of these P2P startups (AirBNB, TaskRabbit, RelayRides, etc.). They are escrow and payment providers each for a specific niche of service provider. Those startups get a nice cut even though the provider plus an escrow partner with no other intermediary might be a good substitute. |

Regarding this "Master Key" business. From Wikipedia: Two-factor authentication (TFA, T-FA or 2FA) is an approach to authentication which requires the presentation of two or more of the three authentication factors: a knowledge factor ("something the user knows"), a possession factor ("something the user has"), and an inherence factor ("something the user is"). - http://en.wikipedia.org/wiki/Two-factor_authenticationA "Master Key" is simply an additional password. Passwords are extremely vulnerable to a replay attack. Please consider adding true 2FA such as OTP / Google Authenticator. If you do add 2FA, please implement it properly -- i.e., always require the OTP for each and every withdrawal request. A plea to exchanges ... lets do 2 factor right! - http://bitcointalk.org/index.php?topic=109424.0Also, there mgiht be a better resolution than "oops, all your coins belong to us" in the case where the OTP is lost. For instance, allowing me to specify an exit address would allow for withdrawal should something happen, like let's say my house burns down and both my phone and the backup copy of my OTP secret are lost. - http://en.bitcoin.it/wiki/Exit_Address |

updated the 2-factor authentication to production. Works with google authenticator.
From the site: Important notice
Always write down your authentication key! You will not be able to log in to your account in case you lose your mobile device.
So let's say I didn't print (or write down) the secret/authentication key and did lose my phone. Is the loss of access to the account permanent (i.e., funds gone forever)? Please consider offering the ability to give an exit address where there is a sane method of recovery if both my phone and the securely-stored authentication code is lost. - http://en.bitcoin.it/wiki/Exit_Address |

Just built this site for tracking lending data and I wanted to test it out.
Forces me to use www. You might want to do a redirect for naked domain requests. |

Pesa is Swahili for money.
And Bel Cibo Italiano is Italian for "good italian food" but it was anything but that. Their menu was only in English, the staff spoke only Spanish and if you wanted more authentic Italian than what they served your options include opening yourself a can of Chef Boyardee. My point was, I didn't think they offered a version of M-PESA in Swahili. Apparently they do: Language: Choose to display your M-PESA menu in either English or Swahili. - http://www.vodacom.co.tz/vodacom-m-pesa/vodacom-m-pesa-customers/m-pesa-customer |

This is the only thing that stopping me from changing all my savings into Bitcoin
LOL, ... put down that glass and step back away from the pitcher of kool aid. If it was clear that Bitcoin would be free from interference from government and banks then you wouldn't be given the opportunity today to buy bitcoin at $13.40 or whatever it is at, as the exchange rate for a millibit would probably already be at parity with the dollar. Recently Phillip Zimmerman was on Adam Vs. The Man: AVTM End of the World Crypto-Party! Phil Zimmerman, Alan Reiner, John Light - http://www.youtube.com/watch?v=bwGu5k6R--oHe was describing how he was under investigation for several years for his work in exporting encryption (considered "munitions"). But they never even charged him with anything. Here's a podcast of a panel with Zimmerman explaining further that period: History of the Cypherpunks - http://www.bitcoinmoney.com/post/6136537609We know various agencies and individuals in governments and banks around the world are aware of bitcoin: List of court cases, complaints, regulatory actions, etc. - http://bitcointalk.org/index.php?topic=96118.0There has not been a single action, to-date, that might be interpreted as the government coming down on Bitcoin. To be fair, Doug Jackson had no indication they would be coming down on e-Gold either, ... until they did. But Bitcoin is not centralized like e-Gold. I'm not saying Bitcoin's exchange rate wouldn't get pounded if there was a move towards outlawing bitcoin trading or commerce, but the technology it uses is such that it will likely survive and continue functioning even if that were to happen. |

It'd be useful for the site to be mirrored or at least some content in Swahili/Kiswahili.
I'm curious if M-PESA (in Kenya) started out with any language other than English. (Or if they even support it today). |

I'll fill any amount of order at gox rates as long as your funds are to me prior to Saturday the 5th.
At what point is the rate determined? Is it the market rate at Mt. Gox when I notify you that I want to buy and am ready to send funds, or the market rate when you receive the funds (or possibly even worse, the currently unknowable market rate on Jan 5, 2013)? |

Common Misconceptions About Bitcoin – A Guide for Journalists by Vitalik Buterin Here are two of the five: The Bitcoin price did NOT fall to $0.01 in June 2011. [...] The root cause was a security mishap at a third party service. Aside from the attacker, no human being was, at any point, willing to sell bitcoins at anything close to $0.01.
Bitcoin is NOT (yet) seeing massive growth in usage to evade trade sanctions in Iran. [...] The media took a single story of an Iranian earning bitcoins by selling music on CoinDL and wrongly extrapolated to a story about Iranians switching to Bitcoin en masse.

- What resources are rigs hungry for eg power, gpu
GPU mining is on its last legs. About the only ones left mining profitably on GPUs are those whose cost of electricity is below average (i.e., they are paying under $0.10 per kWh). The final nail in the GPU mining coffin will be ASICs. Here's the first ASIC:  - https://mineforeman.com/2012/12/28/asicminer-the-dark-horse-in-the-bitcoin-asic-race-may-have-just-come-in-first/If they are successful then it is just a matter of weeks before even those paying two cents per kWh will be kvetching about the rise in the difficulty. |

If I did want to try running a full node on the linux machine, can I simply transfer the blk00xx.dat and index.dat files and not have to re-download the whole thing before it will sync?
Yup, though you will need to do a "-detachdb=1" from the command line once after the move. |

As subject line above read, looking at some units which are rated at GH/s and would like to know what they work out in the more popular MHash/sec.
All GPUs are under 1,000 Mhash/s (for bitcoin mining) so the unit for describing their performance is in Mhash/s. There are FPGA units which perform at better than 1,000 Mhash/s so their performance might be rated in terms of Ghash/s. 1 Ghash/s = 1,000 Mhash/s. ASICs also are above 1,000 Mhash/s (well above) so they too are rated in terms of Ghash/s as well. Now this is just for Bitcoin mining. Other alternative crypto currencies might use a different algorithm and thus a card that performs a certain level for Bitcoin mining can have a completely different rating for the alt chain mining. Litecoin, for instance, uses the Scrypt algorithm. So an AMD 5970 that might do 700 Mhash/s when mining Bitcoin might do under 100 10 [Edited] Mhash when mining Litecoin. The difference would be on a per-model basis versus there being a simple X:Y ratio for comparing how one model might perform versus another. |

Hi EMC support,
At which service are you having this problem? |
|
|
|
How can VirWoX do this without getting scammed? Do people not abuse this service?
Well, the rate is well above spot rate, especially after you complete both trades and have your bitcoins, so they can absorb some fraud that occurs. They also take other measures to reduce risk. If I remember correctly, a request to withdraw bitcoins is delayed for about a day if the account is new, for instance. They might perform other tactics to lessen the fraud that occurs as well. |
