+1

I'm actively using this feature and I would love to give out qr-codes (sealed) of privkeys to friends. Actually I gave one to a friend, but he's not supposed to open it before 6/17/2012. So I'd really love to have the feature in default client by that time Otherwise I'd have to compile bitcoin for windows, which I really would like to avoid.

Most "normal" users don't even know they can use RPC commands. I think compiling a branch is too high a barrier.

This is also needed for bitbills, btw, which is a pretty cool project as I think.

part 2 and 3 are out:

I just go my yubikey from mtgox. It's awesome.

I wanted to use it with online password store lastpass.com, but they want USD 12 / year to become premium member.

I suggested they should accept bitcoin payments. Would be a nice fit, since they're already heavily into crypto and they could really grab up some security-aware bitcoiners with yubikeys.

Not expecting any bounty.

If you can prove the merchant showed you a certain address, you can easily prove you sent money to that address by showing the transaction id.

The first part might be a problem, though, maybe a good merchant should sign a bill including the payment address so customers have proof?

Calculate with +3% lower rate, then, right after payment, automatically try to cash in the money at mtgox. If success: all is good, ship order, if unsuccessfull: tell user you can't sell at that price any more, offer new price or to abort order or return the BTC.

Does this mean I might've generated invalid addresses?

I imported one (the one that had "molec" in it correctly) using importprivkey. If that works, does it mean the address is ok?

I didn't say anyone stopped mining. Mining is still profitable, even at an exchange rate of $5. I said many miners must sell their mined coins.

Just 3-4 months ago, one could mine 20 BTC per day with a €700 EUR machine. You need something like 20 GHash/s for that nowadays, that'll cost you $10.000, and if you look in this thread (watch out, hardware/cable porn): http://forum.bitcoin.org/index.php?topic=7216.msg321184#msg321184, you can see that people are doing this.

I don't think they make such an investment with some "spare fiat money" they have laying around and then just keep the coins, they sell them.

I must object. High supply is a problem if you want the price not to drop (which is implied by OP). A lot of miners decided to join when the price was at $30. They mostly joined for a quick buck, not because of bitcoin and it's features (see troll post above). These people have to throw their mined coins to the market, to recoup their investment and pay utility bills.

according to falkvinge:

1.) unlawfull trade
2.) international trade
3.) merchant trade
4.) investment (not yet released)

in that order

maybe I found a bug, or maybe I'm using regex wrongly:

"./vanitygen/vanitygen -r [Mm]oL[Ee][Cc]" gave me 1H3fttgZCe89zhViCRmk7DX8JmoLJ2mvTV (missing "ec")

found 1BYYdM3vfndwmoLec6tQjcx7sAeLRxTvTq with the same command

try "vanitygen -r [Ww]iLL"

(no need to use [Ii] and/or [Ll] because l (small L) and I are not in base58, I think.

EDIT: found one in seconds: 1NZED7AR8hbwiLLkTWwXgZvM89FZqFiXnj

There's (at least) two ways to change this assertion in order to make it true (instead of false, which it is):

• 1.) higher difficulty => lower price
• 2.) higher price => higher difficulty

1.) is easy to argue: difficulty rises when people freshly investd in mining hardware. They want to recover their investment so they put the bitcoins on the market => higher supply => less value

2.) is also pretty clear: a high price creates incentive to mine and makes mining more profitable => people invest in mining hardware => difficulty rises

I never understood how higher difficulty would drive the price up.

awesome! thanks!

Shhh, silence!

Testcoins are the new bitcoins, but don't tell anyone until I have hoarded enough of them.

Dude, wait! Being responsible for all the friggin' computers and everything that ever happens to them is troubling enough already and I'm more than glad I quit that job a long time ago. Being responsible for my families money being safely stored in some opensource wallet? No thanks!

Rewind a couple of centuries: we have gold, but it's too hard to be used by "normal people" (divisibility, safe storage), so we store the gold safely for them and write down in our books who owns how much gold. Additionally we hand out slips of paper (notes) representing certain amount of gold that can be used by people to trade much more easily than gold.

We can also start a bank and lend this new money to people so they can start businesses. (Of course we will demand interest to cover the risks)
We can even lend out more money than we have bitcoins for, because only a fraction of people will demand to have their bitcoins at any given time (why would they want them anyhow, since you cannot conveniently buy anything with them)
This also gives us a great tool we can offer to people who wish to stimulate (certain parts of) the bitcoin economy: we simply increase the money supply and lend out the fresh money by lowering interest rate and therefore pump more money into the economy. Of course they will also have to pay us back at some point.

Well, "history repeats itself".

It is clear we have currently a problem with adoption of bitcoin and it is unclear wether or not bitcoin can make it without help of sub-currencies.

I sure hope it can: bitcoin is more promising than gold, because

• it's easily divisible
• it's easily countable
• it's easily transferrable

I would really like to avoid the problems that would come with such a solution (and are actually overcome by bitcoin):

• accountability (privacy issues, taxability, need for money laundering)
• trust requirements, security issues
• possibility of fractional reserve banking

I'm not saying you shouldn't go that route, Atlas, but I'm still hoping for naked bitcoin adoption... it'll take a lot more time and effort, though (mobile clients, wallet security, shared keys,...).

I'll be patient.

I made a simple trading client for the mtgox trading api a while back: https://github.com/molecular/traidor

I gave it an overhaul and I thought I'd share it, maybe someone likes it. Features:

• display market depth and recent trades
• display mtgox balances (BTC, USD)
• manage own orders (view, buy, sell, cancel)

To get started, first checkout the code:


then prepare config-file and start traidor:


The most important commands:

Note: you must use a decimal point (".") when entering the <price> of an order. If you dont, <price> is interpreted as an index in the depth table (1st column "[IDX]") and the order is placed just above/below the price at that index.

Some value in mtgox's database are counterfeit coins now? I just wrote "$ 1.000.000" on a piece of paper, arrest me! I just "faked Dollars"!

If bitcoin taught me one thing, it's that (most) journalists are lazy, weak and possibly corrupt opportunists with no self-respect - not to be trusted.
