I've got a question.
The secret is associated with calendar day. But there is no authority for date and time with bitcoin.
This gives some leeway to the service as to which secret the operator chooses.
For instance, at the beginning of each new day an evil operator could determine that one of the first transactions seen would end up a winner and thus instead treat it as if it were still under the previous day's secret, thus denying the prize the transaction should have deserved. Or at the end of a day it could ignore transactions that would win, and wait until the next day (and a new secret) to process them.

To bring bitcoins to the physical world, we need a system that is largely available and cheap (exit the smartphones) Smartphones are largely available and relatively cheap. As these are produced in massive quantities, unit prices are coming down. In parts of the developing world, sub-$100 androids are sold, for instance. When you wanna buy something, you insert the card into the vendor reader. This reader is connected to a computer on wich a special software is running. The software, when a wallet.dat in a memory card pops in, run a bitcoind instance with this wallet, to send the agreed amount.
For security, the user has to enter is passphrase (much like he would enter a PIN with a credit card).
You are missing the next step. The vendor's card reader was hacked by Bob. Minutes after the customer leaves the store, all of the keys from the wallet.dat were used to spend the reaming balance of the wallet. So that specific approach won't work. There have been a number of approaches. Here's some discussion on the topic: - http://bitcointalk.org/index.php?topic=7539.0 |

some of the players are volunteered to do the mining job but some other refused. and some of vlounteered one mining at faster speed but someone else slower. If the game players are start to competing with each other, will they start to "buy" mining power from GPUmax? These are games that charge for subscriptions and in-game currency already. So this is just another option of how to buy them. In addition to being able to buy using PayPal and other methods, they can now pay for purchases with bitcoin-powered credits through CoinLab. |

Or do you play BitLotto for the chance of getting the whole thing?
$1K USD worth of winnings gets into the "that would be nice" But larger numbers -- much larger, like in the $100K range, are more likely to be a topic of conversation and, for now, with bitcoin, would be the only way for someone to get a 10,000:1 or better payoff on a jackpot that pays out 99% of wagers. Having more winners means your chances of winning are higher. Are you considering adding pool teams? That would work if you had a kind of setup similar to how you have affiliates now, just call them pool teams. So I wager on one of the pool teams addresses. If there is any ticket from the pool that is a winner, then everyone in the pool gets paid proportionate to the amount wagered. |

What a coincidence. Dwolla CEO Ben Milne happened to (or still happens to?) also own an online car stereo shop (of which was paying high merchant credit card fees, and thus the catalyst for the Dwolla concept.) But I'm missing something. Mt. Gox fails to transfer money to your Dwolla account, but you are upset with Dwolla? |

I hardly see how another mining tool add any value to the bitcoin economy...
Why not focus on the SMS-payment service instead?
Intel invests in software companies that use lots of CPU cycles, increasing demand for its chips. Google invests in companies that do lots of big data computations, thus increasing demand for its cloud services. etc. So there may be the incentive for CoinLab to help get Bitcoin more widely accepted so that there is more demand for mined coins. Additionally, the article says that they will be hedging coins. I presume this is because as each days worth of bitcoins are earned they they give credit to the players in terms of USDs. So instead of selling daily, the can hedge -- like maybe sell PUT options, or perhaps enter an agreement where there is a payoff if future difficulty rises. This is a type of financial activity that adds to the bitcoin ecosystem. |

Just noticed that the session never expires. Any web-based account that stores funds (my account has a BTC balance) should probably logout when there is inactivity at some point?
Sessions definitely expire on my machines. I think the current expiration time is 2 weeks. Heh. Ok, I must have been thinking "more than 24 hours" and typed "never". Either way, isn't that too loose? This is a wallet where I have money, right? |

I'm a US citizen currently located in a smallish city in China. Cash is out of the question unless you know someone who sells BTC here.
Alipay was used for a short while to move funds into Bitcoinica. Unfortunately, after a bit they had to discontinue accepting that payment method. Here's a thread on discussing those wishing to cash out to CNY. Perhaps you can post a note there saying you would like to cash in. - http://bitcointalk.org/index.php?topic=67272.0And another you might wish to read / post on: - http://bitcointalk.org/index.php?topic=66580.0;all |

$ bitcoin -rescan I am a bit lost on exactly how to do this and what it does. Ya, that was assuming you were using the bitcoin.org client. With mutlibit, I'm going to have to defer to someone knowledgeable with that client. The Multibit thred would be the best place to ask. Are you still stuck in newbie jail or can you post there? MultiBit allows easy export of the keys, so worst case you should be able to import them elsewhere and do the transaction there. You could also try to reset (and re-download): - http://multibit.org/help_resetBlockchain.html |

Confirmed same symptom - Saturday withdraw to Dwolla still hasn't shown up. Note, there is nothing in "pending".
Does it show "pending" in Dwolla? the transfer will sit as "pending" in your Dwolla account until it does.
Right ... if it shows as Pending in Dwolla, then that means Mt. Gox has transferred the money and Dwolla must be holding it. The only time that's been reported is when a user doing the transaction manually picks the "from my bank account" as the source. From there, Dwolla has to do a normal ACH transactions. It has never been reported that Mt. Gox (or any exhange) has been doing withdrawals like this before. So if there are multiple reports of these "pendings", then that needs to be looked into further with Mt. Gox to verify that they wouldn't intentionally start doing that for withdrawals. If instead the problem is a Dwolla withdrawal at Mt. Gox never shows up in Dwolla, the problem then is likely that Mt. Gox didn't keep enough in their Dwolla account and then couldn't serve all the withdrawal requests it had pending. It's something that has been happening every weekend, several times in a row now. If that's a problem, then considering switching exchanges as there are other exchanges that don't have that problem. |

How do they not have the same problems with chargeback fraud that Bitcoin sellers have?
The difference is that for some reason PayPal gives purchases of Linden Labs different treatment than purchases of Bitcoins. Maybe it is because when VirWoX first started trading, purchases for Lindens (SLLs) occurred to be able to use them in-game. Now there is a certain amount of SLLs that are purchased, and immediately turned around sold for bitcoins. VirWoX probably gets fair treatment by PayPal as well. If the customer claims to not have received the SLLs, VirWoX can prove that the SLLs were truly delivered to the account and their disposition from there. So the only fraud that remains is the cardholder claiming the card was stolen / pruchase was not authorized which is probably more manageable. Alos, VirWoX probably has enough volume by legitimate purchases for Second Life users that the fraudulent charges for Bitcoin pruchases is not enough to derail their ability to accept PayPal (e.g, chargeback ratio stays below certain levels.) |
