I will be glad to answer any questions, just go ahead and ask.
It shows that you can purchase a $25,000 car which is a replica of the Project X vehicle. But everywhere else on the page it shows how Wikispeed's strength is in its agile development and the fact that the car gets better each week. So, will the $25k car be the same as the Project X vehicle or will it be an updated version based upon all of the new development? |

Ok, that clears it up quite well.
I suppose that I was able to see the exact transaction because I was using an address that I had not sent anything from before, and was the only address in use in my wallet (was using an Android Bitcoin Wallet app).

It depends on how the transactions that do the spending are constructed. With the Satoshi client, your change is always send to a new address (for maximum privacy) so a typical transaction looks like: Spend:
20 BTC from a transaction using address:ABC123 (I am simplifying here)
To:
10 BTC to address XYZ111
10 BTC to address JKL222 Here XYZ111 is where you want to send your BTC to and JKL222 is your address for the change. With transations like this you do not know (reliably) where your BTC are coming from. The next transaction will probably spend from JKL222 as ABC123 is all spent. This in intentional in the Satoshi client so that it jumbles up the change and the sendee's addresses. Different code bases do things different. For instance by default the bitcoinj code sends change to the first of your addresses used (I do not think there is a particularly deep rationale for this - it is simply the easiest to implement). So for bitcoinj code a transaction looks like: Spend:
20 BTC from a transaction using address: ABC123
To:
10 BTC to address XYZ111
10 BTC to address ABC123 You could then reuse the change on BTC on ABC123 For blockchain.info I believe you can specify explicitly the change address to that you can pop your change back to wherever you like. TL;DR With the right transaction structure you can send from a predictable, repeatable address but you lose privacy doing this. Ok, then it is the concept of "change" that I am not understanding. If you have 20 BTC in address ABC123, why not just send 10 BTC to XYZ111? Instead of sending 20 and getting 10 back? |

I asked here earlier if a Bitcoin sender could tell a receiver what address that it will be coming from. I was told that the user would not know the address it was coming from. Thread: https://bitcointalk.org/index.php?topic=89093.msg982559But I ran a test transaction. I have address: 1KFxTa9tLiM9YayFkdtZ1QvoJs4f7aQhjT and I sent to address: 1ELWAR1qFQbfmpMhcsTaBniFRLewrYqGo2 It shows up here as 1KFxTa9tLiM9YayFkdtZ1QvoJs4f7aQhjT to 1ELWAR1qFQbfmpMhcsTaBniFRLewrYqGo2 http://blockchain.info/address/1ELWAR1qFQbfmpMhcsTaBniFRLewrYqGo2So, if I have the address 1KFxTa9tLiM9YayFkdtZ1QvoJs4f7aQhjT and I told the receiver to associate a transaction from that address with my information, would the receiver not be able to verify that any amount sent from that address is from that user? I am thinking about this not only for merchant transactions but for a voting system I am developing where only people within a group can vote by sending BTC to a single address. The site would verify the source address as someone in that group and everyone would be able to view the vote counts via the blockchain to a "Yes" or "No" address. The reason you would want to know the source address is so that someone does not just pop up several addresses and send in false votes. Any clarification would be helpful, I am digging deeper into the mechanisms of how things work and how to put it to use. EDIT: Ok, I understand now. Clarification needed in my last post. |

I am surprised you are allowed to be on this website.
I call for a ban!

Speaking of...
I set up the Android Bitcoin app on my touch pad and was looking for the file last night. I searched the directory for wallet and found nothing.
Also, if I just write down the PrivKey I should be able to load that up at some point in the future to send BTC right?
Which app was it? Bitcoin Wallet for Android |

Or you could say...
"If bread ends up costing $100 per loaf, how the hell do we cash out if we choose to?"

I just got my Raspberry Pi yesterday.
I did not actually purchase the power chord with it. Is that something I can buy at Radio Shack or will I need to order it?
I was considering using it as a streaming device for my TV.

Nightly Bitcoin training and exchange.
Interesting Could you elaborate what kind of training would go on? Maybe like a projector or perhaps everyone brings their own laptops and can follow along or something like that? Everyone bringing their own laptops would certainly be helpful. The training would basically be...how to set up a Bitcoin wallet and get some bitcoins (the exchange part being useful for them getting their first Bitcoins). From there you could show people some websites of places that they can spend their bitcoins. You could have a separate training session for Bitcoin merchants, showing them how to set up Bitcoin payments on their webpage or using bit-pay for POS transactions or other ways of accepting BTC. If they bring their laptops, they can set up their wallet securely right there. Or you could have a computer there and show them how to create a wallet and put it on disk or thumb drive, then let them keep the disk (letting them know that they should transfer the BTC to a new wallet when they get home). You could also show the basic steps on how to get BTC through MtGox or Bitinstant or others. There is much to learn, most likely the basics will be a good start. The exchange would be key. It could also help with funding. |

Here's a mathematically, cryptographically proven process for recovering bitcoins sent to a valid but otherwise unintended address. A vanity address generator can be used to reverse-engineer the private key from the (public) address. Take the Bitcoin address you accidentally mistyped (which now owns your bitcoins) and put it into a vanity address generator. The generator will create and test private keys until it finds one that produces a public address matching the one you're looking for, at which point you have the private key to reclaim your funds. Of course, you may need to wait several thousand years to find a match. The upside is that, by that time, Bitcoin will surely be the dominant currency in the local extra-solar economy, and your small sum today will certainly be worth quite a bit more due to deflation (only 21 million bitcoins being spread over a multi-planetary market).
Hope this helps.
This. You may want to get started now. |

It would only boost the bitcoin market if the retailer were large enough. My wife's shop offering 30% off for using Bitcoins would get 1, maybe 2 people to buy with Bitcoins based on such a sale.
The key to such a strategy would be knowing that there would be an influx of consumers by doing such a promotion. This is currently not the case.
If you were to get a pool of Bitcoin users to start pledging a certain amount of BTC, then once they have accumulated enough BTC pledged then certain retailers may bid to be the retailer of choice. Then those pledged spenders spend their pledged money at that retailer.
If you could get a couple thousand BTC pledged and spend it all at one place, then it could make some headlines.

This is a decent idea. It would be more like joining a club. You join clubs for certain benefits, you vote on fees, dues and rules and what to do with those fees.
It would be interesting if such a club/country were to grow to the point where it can pay for its own military and go in and protect its "citizens" from tyranny. A virtual world fighting against oppressive nations...interesting to think about.
I have always considered the best method of "taxation" as an up front fee from new members. That way you have a full understanding of costs as well as a full understanding of the current rules. If the rules change then you are not forced to pay more into it and you are coming in knowing how rules are made and changed. And if you do not like such a system, you are not forced to join.

I have always said that if I were to mint gold or silver coins for distribution I would just offer advertising on part of the coin to pay for the minting costs. That way, people could get the coins at the cost of the metal.
It would not work so well with this application as the paper is going to be thrown away and will not be widely circulated.

The bad thing about this is if the market tanks before people withdraw and convert to USD... well you get the idea. But if the market skyrockets then WHOOO!!! No complaints here  Fortunately there has not been that huge of a fluctuation over the span of a month for quite a while. But the price fluctuations would not be too big of a deal as most of the money spent will be within days or weeks or receiving it in your account. As most people live paycheck to paycheck. |
