We are all thinking about people keeping their coins on their own devices, but people may use web services too.
If both customer and retailer use MyBitcoin for ex., transaction confirmation could be instantaneous. In the future probably there will be many sites like mybitcoin, and they will have ways to integrate their transfers. Mostly like the banking system, "only" without the central bank.

One weekend that I stay away from the net and there are more than 300 messages unread from this forum... I can't keep your pace anymore! 

So, an account balance doesn't always equal the summed balance of all address that belong to this account, that's right?

Bitcoins are not pegged to anything, if that's what you're asking. Their price floats freely.
There's no institution behind bitcoins, it's a P2P currency.

hehe, peter, at least read the FAQ...

They remain down... it's bad, they are the most practical exchange for those who have euros.

You don't know what you're talking about.

Ah, I hadn't understand your question at first, now I see the problem.

Hum, you could try to make some sort of dependent transaction... Something that only gets accepted by the network after some other transaction takes place in the main chain...
Like, the generator adds a transaction, with a sort of message: only valid after bitcoin address A receives X bitcoins.... if the address never receives the money, a future block generator could add again the same transaction but asking less...

It would be better if there could be some sort of bargain between the sender of the transaction and the generator, but I can't see how.

The way I thought, you wouldn't be doing any real extra work to generate for the dependent chain. Your hashing is just for the main bitcoin chain. Once you generate a block there, you use that block private key to sign something that gives you the right to create a block on the dependent chain. There's no hashing for it.

You get the bitcoin reward for the block you produced in the main chain and only that, since you didn't do much more than that anyway.

And for a long time they have been poorer than the western European countries. By the way, most poor countries, if not all, do have a large portion of their economy in the "dark side".

Black markets are not equivalent to free markets. The results aren't the same.
I hope these so called agorists find a way to make them be, but I'm a bit skeptical, at least for the short run. I think most governments will keep growing until their size make their ruled society so miserable that the state's own legitimacy gets threatened. At this moment, they might back off and allow more freedom, because they wouldn't have much other choices.

I agree with jgarzik, the chain should not be used as storage.

If you want to create your own proof-of-work chain but would like to avoid double-work, you could make your parallel chain "dependent" on the bitcoin chain. Like, for creating a block in a dependent chain, you first have to create a block on the bitcoin chain and then use the private key you used to create that block to sign your new block on the dependent chain.

I agree on the premise that we can't expect anything from the political process.

But in your conclusion is complicated. If people just start running away from the state, that'll make it more intrusive and aggressive. Living in the "black market" is always difficult. By black market I mean anything not official, like undeclared labor, ambulant sellers who don't pay taxes etc.
Don't fool yourself to think that a black market is just like a free market. It is not. The simple fact that people have to hide from the state limit them a lot, there are lots of things capitalism can provide that they cannot use because of their hidden condition. Trust becomes much more complicated as you have no means of pursuing some one, at least not in a "civilized" manner. When you can't trust anyone like this, your circle of relations gets much smaller, what limits the benefits of capitalism.
If you ever had the chance of reading the book The Mistery of Capital, you get an idea of what I'm talking. Or, if you grew up in a third world country like me, you probably already know it. My country has something like 40% of the economy in the "dark side", and that doesn't seem to help people, on the contrary... those working on the black market are mostly the poorest.

I hope the internet (and bitcoins ) provide the means to people to escape government and also avoid all the problems unofficial markets have today... let's see.
(also, I hope the seasteading project becomes a reality soon )

I find it a bit dangerous to give the final decision to the buyer.... at least in retail, it's the seller who has a reputation to care for. Buyers have less to lose in cheating.

Not complaining about your site though, it's a good initiative.

What's a non-standard transaction?

It has to store both, you can't deduce the public key from the private key...

This is another reason to have a more modularized bitcoin software... someone could make a wallet-management module that uses a database instead of a file, to better scale...

Is the wallet.dat file indexed?

Have you tried to announce your service on Tor-users forums?

It's a delicate dilemma I'd say.
Is a slave that accepts a gift from his mater accepting his slave condition, or being hypocrite?
Even when you know that the gift was produced with the stolen labor of other slaves, it's complicated to condemn the one that accepts it...

While I was a student here in France, I benefited from their rent-aid program. I think such program should be extinguished, as many others, but anyway, I did get money from it.
Now that I have a job they have already taken much more money from me than what they gave me before, so I don't regret at all.

The idea is nice.
But the image doesn't make me think of money... maybe inside of a coin?

Did the value of gold drop sharply after the ban in 1933? (I really don't know)

If the value kept, it means that people kept "hoarding" it as a "store of value". Maybe even if all exchanges are outlawed, people will still keep bitcoins just to protect their money against Bernake's gang.

And, by the way, bitcoin is international... such ban would have to be orchestrated by most governments of the world to be that serious, otherwise it would be just "free advertising" as someone just said.

I didn't know about this, that the protocol was "hard-wired" to the default client.
Your suggestion is really important. Client software and protocol should be separate.
It would help to have a protocol specification for this. The protocol version would only change when changes to the specification are made, not at every release of the client.
