Questions about BitCoin
I started implementing a marketplace feature earlier that facilitates offering things for sale and taking orders, it's only half done though. A bit like e-bay but without auctions, just "buy now". Among other things, it would make it easy…

Re: Bitcoin
That's a good point that since you know how many coins exist and how fast new ones are created, you could set a support price based on the amount of legacy currency you have and be sure you'll have enough to meet all demands. I had…

Re: Setup, Autorun, v0.1.6
Thanks for that. I'm still merging in some changes I had that need to go in before any next release. Some things based on questions and feedback I've received that'll reduce confusion. I'll probably enable multi-proc generating support,…

Re: \[bitcoin-list\] Does Bitcoin Crash in Windows?

Linux build ready for testing
The Linux build is ready for testing on the network. It seems solid. I sent the executable as an attachment in the previous e-mail, but if the mail server didn't let it through (it's 12MB), you can download it here:…

Re: Linux build ready for testing
In the debug.log, it requests the block list, receives the block list, then begins uploading the list of blocks requested. It doesn't receive the blocks, but it didn't run long enough for me to be sure it would have had time yet.…

Re: Linux build ready for testing
Thanks for that, I see what happened. Because the first one was slow, it ended up requesting the blocks from everybody else, which only bogged everything down. I can fix this, I just need to think a while about the right way. There's no…

Re: Linux build ready for testing
You really don't want to keep running in Wine, you're getting database errors (db.log). You probably developed these rituals of transferring to a fresh install to cope with database corruption. If there is a way to lose unconfirmed…

Re: Linux - dead sockets problem
I see what happened. All your sockets went dead somehow. You had no communication with the network, but because you had 8 zombie connections, it thought it was still online and kept generating blocks. You can tell this is happening when…

Re: Linux - linux-0.1.6-test2
I fixed a few places I found where it was possible for a socket to get an error and not get disconnected. If your connections go dead again, it should disconnect and reconnect them. I also implemented an inactivity timeout as a fallback.…

Right now (04:50 GMT) my node is connecting to yours and getting zombie connections each time. The socket isn't returning an error, just zombie without notice. If you're running the linux build right now, it would be interesting to see…

linux-0.1.6-test5 fix for zombie sockets

Re: Db::open/Db::close "Bad file descriptor" exception
I have an idea for a workaround, but it depends on what files the errors are on. If you've accumulated several errors in db.log, could you send it to me? (even if it's rather simple and boring) Is the file listed always blkindex.dat, or…

Re: linux-0.1.6-test7
Finally an easy one. I see a way that could happen on a long operation such as the initial download. The TryLock bug is unrelated to the db stuff. Fix will be in test8. I've been able to reproduce the db::open/close exception 3 times now…

Exchange options
Don't rush ahead and get yourself rejected from all the payment options before you've had time to see if there's a better approach. I suggest you wait before contacting any more payment processors. You may get ideas from things other…

Exchange ideas
You could always exchange for Liberty Reserve. It's an online currency similar to e-Bullion, Pecunix or Webmoney that allows exchanges no questions asked and with privacy. LR and the others are hard to buy but easy to cash out. Hard to…
- Private email (Martti Malmi)
Re: Exchange options
Maybe the current difficulty of buying LR is already the limit of how easy it can get in that direction. Every conventional payment method has refutability as their way to cope with their lack of passwords and crypto. The system is wide…

Re: Repost: Request: Make this anonymous?
True, sending by IP through Tor trades one problem for another. The Tor exit node can see the text of your message and potentially MITM you. Best to only send to bitcoin addresses then. Payments by bitcoin address are broadcast over the…

Re: Current Bitcoin economic model is unsustainable
Excellent analysis, xc. A rational market price for something that is expected to increase in value will already reflect the present value of the expected future increases. In your head, you do a probability estimate balancing the odds…

Re: Money Transfer Regulations
When there's enough scale, maybe there can be an exchange site that doesn't do transfers, just matches up buyers and sellers to exchange with each other directly, similar to how e-bay works. To make it safer, the exchange site could act…

Re: Exchange Methods
LR and Pecunix have many established exchanges to paper currencies by various payment methods, and a number of vendors accept them as payment, so an exchange link between Bitcoin and LR/Pecunix would give us 2nd-hop access to all that.…

Re: We accept Bitcoins
Almost but not quite. Bitcoin uses EC-DSA, which can only do digital signing, not encryption. RSA can do both, but I didn't use it because it's an order of magnitude bigger and would have been impractical.

Re: BTC Vulnerability? (Massive Attack against BTC system. Is it really?)
What the OP described is called "cornering the market". When someone tries to buy all the world's supply of a scarce asset, the more they buy the higher the price goes. At some point, it gets too expensive for them to buy any more. It's…

Re: Bitcoin minting is thermodynamically perverse
It's the same situation as gold and gold mining. The marginal cost of gold mining tends to stay near the price of gold. Gold mining is a waste, but that waste is far less than the utility of having gold available as a medium of exchange.…

Re: BitDNS and Generalizing Bitcoin

Right, the exchange rate between domains and bitcoins would float. A longer interval than 10 minutes would be appropriate for BitDNS. So far in this discussion there's already a lot of housekeeping data required. It will be much easier if…
