Bitcoin can already pay to an IP address. It wouldn't be a big deal to add DNS support. Maybe an address in a TXT record could be used as a fallback if the IP address isn't accepting payments.

DNS and IP transactions aren't secure, though. (DNS will be perfect for this once DNSSEC is available everywhere.)

The number issued is hard coded to the width of a certain crypto key.

BitCoin is based on several important aspects of cryptography, I guess BC uses symmetric and asymmetric cryptography at the same time.

LOL. These people have no idea what they're talking about.

Bitcoins aren't infinitely divisible. The smallest amount is 0.00000001. Once the halving would make a subsidy lower than this, the amount will go to 0 because the calculation is done as a bitwise right shift (of an integer holding the number of nanocoins). It just so happens that the total number of coins in this scheme ends up being very near 21 million (20,999,999.9769)

Even if the precision is greatly increased, the number of BTC in existence would never go above 21 million. See:
http://theymos.ath.cx:64150/btcstat.php?q=changeparams&precision=200
(Changes precision to 200 instead of 8.)

We are currently using the address: 1MCwBbhNGp5hRm5rC1Aims2YFRe2SXPYKt, however the market site states, "CAUTION: ALL BITCOIN ADDRESSES FOR DEPOSITS HAVE CHANGED" and I'm not certain what that means. What am I missing?

Tell them that this is only relevant for people who had BCM's receiving address saved. BCM regenerated everyone's unique address for deposits into BCM.

The warnings at the top of bitcoin.org, bitcoin.org/smf/, and BCM don't look good to outsiders... It makes the system look unstable.

And yes, since the documentation for the "lose all yer bitcoins" behavior is found only in threads like this, that's a bug and a damn big one.

A warning about this was in the very first revision of the wiki's "backup" page (from July).

An elegant and anonymous solution will be implemented at some point (a list of queued addresses will be included in wallet.dat for use with change). Until then, deal with the fact that this beta software requires more frequent backups.
7666  Bitcoin / Bitcoin Discussion / Re: Bitcoin in RALLY mode on: October 08, 2010, 02:49:44 AM
I don't see how this can last. 100,000 BTC in bids+asks on MtGox, but 7,200 BTC are created every day. The market just can't absorb it.

Of course, I've been bearish about the market since I was selling (below the normal market rate) at 0.003.

If you give the user a machine that can decrypt something, and then you give them the key and the ciphertext, then they can decrypt it. You can make it difficult if you make them use special hardware with the key/ciphertext/encryption embedded, but you're still giving the information to them, and it's still possible to reverse-engineer.

I played the demo. It's an interesting casino game. The odds are certainly against you, but it's possible to make a profit. There's one 2-player game (so far), and if you're good at it you could clean everyone out.

I saw two slot machines, a unique multi-player/community game, a coin-flip doubler type of game, and a two-player bluffing game. Also, nearly every plant in the game is a gambling device with different odds. There are tons of opportunities to gamble.

What it comes down to is that only the program itself "knows" the bitcoin private keys and the code inside the cointainer.  They would never be revealed to the host.  I don't mean security by obscurity like spaghetti code, what I mean is that no amount of reverse engineering would reveal the contents of the container.

This is impossible. The CPU needs to know the encryption key to decrypt the container; there's no way around this.

What will you do if the major governments make Bitcoin illegal and actively try to shut it down? Will you resist them?

If Bitcoin becomes bigger than PayPal, how do you see the organization of the project? Will you continue to develop it more-or-less alone, will there be a secret group of developers like TrueCrypt, will it be a massive community-driven project like Firefox, or what?
7671  Bitcoin / Development & Technical Discussion / Re: Tor connections not working reliably, many seednodes offline on: October 06, 2010, 05:56:18 PM
How long did it take to get connected with TOR the first time, having to use the seed nodes?

I gave up and used -addnode after 10-15 minutes.

I definitely was unlucky in exit node selection, since I've been able to connect to IRC with Tor a few times since them.
7672  Bitcoin / Development & Technical Discussion / Tor connections not working reliably, many seednodes offline on: October 06, 2010, 01:59:38 AM
While I was trying out Bitcoin with Tor a while ago, I found that it was impossible to get connected in a reasonable amount of time. See the debug.log excerpt below.

I know that the guy who operates irc.lfnet.org is around here. Maybe he can remove that hostname limitation, since it's blocking some users.

Also, most of the seednodes are gone. Only 37 out of 230 are accepting connections on port 8333. This makes connecting without IRC very slow. The offline ones should be removed. A list of online seednodes is attached.

That might be the case with SHA-1 and RSA/DSA-1024 (used by default in old versions of PGP), but the SHA-256 and ECDSA-256 algorithms used in Bitcoin can't be cracked in any reasonable time with current technologies. NIST believes that these algorithms/keylengths will be strong past 2030.

The Bitcoin genesis block contains a newspaper headline, which is supposed to anchor the start of the chain in real time. The choice of headline gives some insight into the project's purpose, I think:

Neither can you "owe" a Bitcoin. Sending someone a bitcoin does not oblige the payee to do anything in return.  Reciprocity is based purely on reputation. There is no enforcement of reciprocity.

If we have a contract where I provide the service of creating a valid Bitcoin transaction of a certain value in return for a good, and you fail to deliver the good, then you have breached the contract and must return the current market value of the service (bitcoins) I provided.
7676  Bitcoin / Bitcoin Discussion / Re: Prioritized transactions, and tx fees on: October 03, 2010, 09:32:08 PM
Is there a technical limit beyond this artificial one?  Would it just be the bandwidth available to the weakest (in terms of bandwidth) nodes, or are there any inherent limitations of the p2p network itself?

If there are any technical limits (from data types or whatever), they can be eliminated in the same way that MAX_BLOCK_SIZE can be increased.

Storage is the main issue, I think: an attacker could create huge blocks that every full network node has to store forever. With just 1 BTC you can create a block of 15+ GB by splitting it into 100,000,000 "nanocoins".

In the future most people will run Bitcoin in a "simple" mode that doesn't require downloading full blocks or transactions. At that point MAX_BLOCK_SIZE can be increased a lot.

Block 83018 (00000000002bba570c3) cleared out a bunch of them. Last I heard nanotube still had one that's unconfirmed, though.

Edit: Nanotube's transaction cleared recently. I don't know why it was delayed, since it wasn't relying on a sub-0.01 transaction.

Dwdollar moved all Bitcoin Market deposits to a new wallet. That could be it.

Applying this patch will make you incompatible with other Bitcoin clients.
7680  Economy / Trading Discussion / Re: Selling information with bitcoins on: October 03, 2010, 08:25:54 PM
This could be used in a modified BitTorrent client where the initial seed charges 0.1 BTC per piece or whatever. Every peer just has to load up their client with 50 BTC and start downloading from the seed and those peers that will share. Maybe the peers could charge a small amount, too.
