Bump.
82  Economy / Auctions / Auction - Domain bitcoinmegabucks.com starting at 0.01 BTC! on: June 23, 2014, 11:29:21 AM
I registered this domain name back in 2011 with the intention of eventually starting a Bitcoin related game or lottery. I've since taken on a lot more projects and don't see myself ever using this domain.

Bidding starts at 0.01 BTC with minimum bidding increments of 0.01 BTC.

Auction ends four days from today:

It was from a website.

As others mentioned, if the private keys were generated by someone else, they have the option of keeping a copy and retaining the ability to access them.

I hope you didn't give anyone money for these.

I agree that finding private keys via brute force is not possible  Grin

But what if an agency such as the NSA simply goes ahead and reserves all 1,461,501,637,330,902,918,203,684,832,716,283,019,655,932,542,976 addresses for themselves? That would kill BTC wouldn't it?  Huh

There's a difference between knowing the number of possible combinations and actually doing anything with them. We've established that even just generating them, a process that takes just a fraction of a second for each, would require more time than we have before the heat death of the universe.
87  Bitcoin / Project Development / Re: [SUPPORT] www.Btc-Embassy.com -- CHECK OUR BLOCKCHAIN.INFO GUIDE and ATM !!!! on: June 17, 2014, 11:24:50 PM
Hi roslin, first of all i'm glad that you're continuing to support the embassy as promised in the beginning of the project. Do you think that it can be hard to implement an internal bitcoin payment system for buying services or virtual products during the visit?

Well, if there will be anything to buy in our Embassy it will be something connected to someones service - like an exchange or an online shop.

So we don't have to implement an internal bitcoin payment system, as this would be very hard indeed.

Well there are some ideas about it but I don't want to tell all of the secrets Smiley

As for now developing is focused on guides, ATMs, other cool components, multiplayer etc.

Cheers!

I've been corresponding with roslin and I believe the intention is to keep the focus on being more of a resource for Bitcoin newbies than becoming a money making machine, at least for now. I've made some suggestions as to how this project might support itself and roslin has been very receptive but things are still very malleable. In any case, there's nothing stopping users from conducting business within the environment and displaying their own BTC addresses generated elsewhere.
88  Alternate cryptocurrencies / Altcoin Discussion / Re: Cryptocurrency Scam Trading cards - the world needs them. on: June 17, 2014, 02:11:04 PM
I like the idea but why not go further and create a crypto card game of some sort. Loads of crypto freaks are also geeky table top gamers who love card games.

Maybe an open source crypto card game. With all the proper files and instructions you can print at home or take to a local or Internet print store. Your cards will only look as good as you make them.

I really like this idea. Anyone who wanted could submit illustrations and rule variations and even expansion packs.

Would you trust a "no name" retailer holding your money for you while you shopped (for much smaller businesses)?

If a shop is processing many large ticket transactions per hour, they've probably already established themselves as reputable.

I had an idea like this about a year ago and have been creating cards and a game based on them in my head since then. I have a graphic designer whom I've worked with in the past also who would be perfect to do this. To do it right, however, will take a little more capital than I have available, not much, maybe 10 BTC to get a few dozen starter sets printed. If anyone wants to partner up, I'm happy to discuss some possibilities via PM.

If bitcoin were to catch on enough then it would be possible for there to be 5 or 10 people in a row for example to be issued a claim ticket waiting for transactions to confirm.

A semi centralized service like greenaddress, circle or coinbase could solve the issue, as the store could advise customers to send their bitcoin to their account at one of the above services when they enter, then TX gets confirmed by the network while they shop, then the customer pays for their merchandise via their account at one of the above, then withdraws their coins back to their wallet that they did not spend.

It still wouldn't be necessary to involve a third party. Businesses could require their own pre-paid gift cards for  big ticket items. Simply load it with bitcoins before you leave the house and they're confirmed by the time you get to the store. Unspent funds can be refunded by the cashier.

- Wonder how Coinbase instantly validates?
 

Because you would be paying with your coinbase account, so they are really controlling
the funds.  They are the trusted third party.   This is another LAYER.  Essentially, you are telling
coinbase to pay them, and the merchant is assuming coinbase won't double spend.  Hope that
makes sense.   



Both coinbase and greenaddress would be good to be sure that payment will be received with dealing with high value items.

If you are only selling low value items (a few dollars) you should not worry about double spending attacks as they are generally expensive to execute.

But that would require both consumer and merchant to have accounts with the same service.

In any case, if it was a high value item, why would you mind waiting for one confirmation?

You should not mind, in general.

The issue would come into play when you are selling high volume items in masse. Say for example someone is buying  a computer at Best Buy, the buyer would not mind waiting 10 minutes for the TX to confirm, but the seller (Best Buy) likely would. Now a transaction that could take 30 seconds to a minute will take, on average 10 minutes (if it gets confirmed in the next block), meanwhile everyone in line will need to wait, making their employees less efficient.

For a transaction like that, I imagine the clerk would put your purchased items to the side, issue a claim ticket and move on to the next customer. Once the first confirmation goes through, the items are released.

Alternatively, the cashier can verify an adequate transaction fee was included (to minimize the risk) and obtain ID so that, in the event of a (still very unlikely) successful double spend at least the perpetrator can be prosecuted.

Brick and mortar businesses already accept a certain amount of risk with current payment methods. IMO, bitcoins are still less likely to be spent fraudulently and a few precautions practically eliminates the possibility of falling victim to a double spend without inconveniencing customers more than they already are.


Anyway, I believe the OP wishes to operate a site that somehow will allow users to conduct business with high values of BTC extremely quickly and possibly anonymously without any risk whatsoever. I think that's asking a little too much of Bitcoin this early in the game. We're still in beta, remember?  Wink

Would not surprise me if someone working for the FBI claims their silk road bitcoins got hacked, after sending it to themselves  Grin

Reminds me of this:

Why would the gov need to do housekeeping on a btc wallet??

You'd have to ask them.  I'm sure there was some sort of paper work involved and probably some bureaucratic nonsense.

Could be any number of reasons. For example, control of the coins could have been turned over to another department/office/individual and he/she/they wished to eliminate the possibility that the previous guardian could still access them.
98  Bitcoin / Bitcoin Discussion / Re: Do you USE your BTC? on: June 08, 2014, 07:11:48 AM
I don't worry about Bitcoin adoption anymore. I sincerely believe we've hit critical mass. The number of businesses that are accepting bitcoins is growing every day and the network has withstood quite a few issues over the last few years. In addition, while your average Joe may not really understand Bitcoin, he's probably heard of it and might even be curious about it.

When I started BitBrew, I wanted to encourage Bitcoin hodlers to participate in this economy and there weren't many places to do it. Now, if there's a niche still waiting to be filled, I can almost guarantee someone's about to fill it. What's needed now are more ways for people to earn BTC and that's one of the reasons I teamed up with the Bees Brothers to start the Bitcoin General Store; I'm always on the lookout for producers of quality goods willing to accept bitcoins so that we might offer them a spot on our virtual shelves.

There are plenty of sites that give you the option of paying with PayPal, CC or bitcoins. PayPal only disallows buying or selling bitcoins directly using their service.

Using new addresses for all Bitcoin transactions is the best way to track payments. I generate a few thousand at a time and load them into a database to be presented at checkout. Why re-use addresses when it cost nothing to get a new one and avoid all possibility of confusion?

The part about PayPal, could you pretty much guarantee that? I am dying to set-up a 'pay with Bitcoin' option on his site as I redesign it. There would Definitely be no buying or selling of BTC on this site. Just 'Pay with PayPal' and 'Pay with BTC'. If you could pretty much promise me we would be alright doing both it would make my day. He gave me full creative control over it, and is down to start with BTC. The only thing is, PP is currently the Only option he has on there of receiving payment. If somehow things got fucked up and his site got "kicked out" of using PayPal, I could never regain the trust and respect I would lose.

As for the second part, is this what I need to do: Set-up a MySQL database with a bunch of different generated BTC addresses, then when they click "Pay with BTC" some php returns a new, unused BTC address from the database?

That is just what I'm thinking would need to be done. Thanks for the help.

I can't speak for PayPal.  I suggest reading their TOS.
