But if you legal have the money (no fear of government taking it) ...

one word: inflation.
via inflation, government takes your money (reduces purchasing power of your money). regardless of whether your money is squeaky clean, or dirty as dirt, government will take some of it via inflation on a continuous basis.

Here's an interesting and perhaps non-intuitive consequence of the way generation works. If the difficulty increases, your rate of generation drops. If the increase in difficulty causes some people to drop out of generating, your rate of generation doesn't go up again. When other people drop out, it makes it take longer until the next difficulty adjustment, but you can still expect to generate the same number of coins per day until then, no matter what other people do.

Would it be possible for the clients, and thus the network, to determine that no blocks have been generated in X time, and to decrease the difficulty by Y amount?

it is possible in theory, but there are problems as far as determining "the time", and it would require all (or majority) of clients to be upgraded to the new version.

could also try for json instead of xml. json seems to be easier to work with, and is also the accepted standard for representing various bitcoin data structures on output by the various tools currently in existence.

207  Economy / Marketplace / Re: Are you willing to pay for a psychological experment? on: February 13, 2011, 08:09:55 PM
Full marks for trying! :-)

There's no way to force the bitcoin client to spend a generated coin rather than a traded coin, by the way. And if there was, people would keep their generated coins for when they absolutely need the maximum anonymity.

well, if you keep a separate wallet for your generation, you could. Smiley

try #bitcoin-otc, maybe. Smiley (link in sig)

mndrix: a suggestion for you
you should also offer to buy bitcoin in exchange for paypal.
no risk for you, plus way to refill your bitcoin stock.

there has been some talk on #bitcoin-otc about demand for ability to sell bitcoins at a fixed price without having to deal with forex trading on the markets.

oscon proposal deadline almost here
curious if anyone has done anything about this?

Almost everyone had transactions from "united". It does NOT mean that your account was compromised. It does mean that the attacker has your username. It was just them using the merchant API to send you 0 BTC.

There were only two accounts that had money stolen from them as far as I can tell.

It was a dictionary attack since I saw it happening.

I plugged the vulnerability that allowed them to run the attack so your weak passwords will be safe again.

I'm still working out with cryptofo if/how to reimburse him.

Ideally Liberty Reserve would help us since they can easily fix the issue. But they don't seem to be cooperating. Anyone have ideas there?


libertyreserve doesn't ever reverse transactions. they're trying to be a 'hard currency'. so you're pretty much SOL there.
213  Bitcoin / Development & Technical Discussion / Re: [RFC] Testnet reset on: February 01, 2011, 06:43:09 AM
Yea, that's nice, but will we reset the main network the day someone pulls the same trick on it ?

No, if necessary we'd change the difficulty adjustment rules and make the code:

if (current block is > some_number)
  ... new rules for adjusting difficulty
else
  ... old rules for adjusting difficulty

I could have done that and kept the testnet block chain, but it is cleaner to just reset it with new rules.

And "pulling the same trick" means throwing an overwhelmingly massive amount of hashing power at the main network (like 16 times the current overall hashing power) for a significant amount of time, which is getting increasingly hard to do.


i for one would prefer this approach to completely restarting the chain.

suggestion:
henceforth, 1e-8 bitcoins will be called "a bitcoin".
all bitcoin amounts will henceforth be integers.
sending 1 "oldbtc" to someone? just send 10million 'newbtc'.

solves all problems very neatly.
and also removes any psychological barriers around having "1 btc = 100usd"

EDIT: that said, i essentially like gavin's proposal, except for the cosmetics. Smiley

I strongly disagree.

<snip>

An other, yet compatible possibility is to start from bottom :

1 coin = 10^-8 BTC
10^3 coins = 1 kilocoin = 10^-5 BTC
10^6 coins = 1 megacoin = 10^-2 BTC
10^9 coins = 1 gigacoin = 10 BTC

So one bitcoin would actually be 0.1 gigacoin, or 100 megacoins


so in other words... you agree. ok. Smiley

You might want to try #bitcoin-otc, but note that not many would trust you based on your posting.

since he's the one with the hard currency (lrusd), should be easy to get ~ 1:1 exchange for ppusd or some such, on bitcoin-otc.
217  Economy / Marketplace / Re: New game =)) on: January 31, 2011, 04:29:45 AM
yea how do we know if you yourself didn't send out the 50 btc before posting it. Tongue
218  Bitcoin / Development & Technical Discussion / Re: Bitcoin suddenly failing on start on: January 24, 2011, 06:51:23 PM
IMHO, most "average users" should be using a website, rather than bitcoin software.

bitcoin software is mainly for highly technical people, or people very interested in privacy (ie. they might run bitcoin over Tor).

or people interested in not losing their bitcoins due to some site either (a) absconding with people's bitcoins or (b) getting compromised and having its bitcoins stolen...

until there are real corps out there, with real account insurance and everything (think SIPC), i can't really recommend anyone to stick all their bitcoin wealth onto $randomsite.

220  Other / Obsolete (selling) / Re: selling contracts for performing 30 petahash calculations in bitcoin network. on: January 21, 2011, 07:30:07 AM
nice service, and i wish you best of luck with it.

but for your information:

190*12+1600 gbp = 3880 gbp = 6176 usd

at 6176 usd, at a price of .4 usd, you can get 15440 btc

at 1 ghps, with current difficulty, avg time per block is about 1 day. so you can generate 365 blocks per year with this, or 365*50 = 18250 btc

however, difficulty will almost certainly go up from where it is now. in fact, at the next estimated difficulty of 22037.22945411, your expected yearly generation at 1ghps is already down to 16590 btc or so.

so, it seems a better deal, if you have the 3880 gbp to spend on this, to just buy bitcoins on the marketplace at current market price.
