381  Bitcoin / Mining speculation / Re: Does anyone have estimates of the cost of a 51% attack at various times? on: August 21, 2013, 02:55:00 AM
Even if you had the money, nobody is producing enough equipment for you to buy it.

Exactly.  Unless the attacker created an ASIC or has had 50% of the orders in with the existing manufacturers there's simply no amount of money that will yield enough hardware to get 50% of the hashing capacity out there.   Perhaps a globally coordinated seizure of output from all the ASIC vendors might get the attacker that much hardware but then the chance of a "surprise" (necessary for executing a successful 51% for the purpose of double spending) drops to zero.

As far as i understand each type of goods has an issuer. Who is the issuer of Bitcoins in that system? Or would i issue Bitcoins by claiming i have some?

A Bitcoin voting pool is described in the Auditing page on the OT wiki.  As is auditing for physical:

there is a need for a different taxation system than we currently have.

Cash is a payment method that too can be used anonymously.  The use of cash hasn't caused the current taxation system to be abandoned.
388  Bitcoin / Technical Support / Re: Double-spending vs Double-spending on: August 20, 2013, 05:48:52 PM
Obviously 1. != 2. so I think we should use another word for describing 2.
I've never seen anybody using another word, did you?

A spend with Bitcoin is a "confirmed" transaction.   Most services do not credit a transaction as confirmed until there are six block that have confirmed the transaction.  

So 1 == 2 in that context (with the exception of systemic failure like what happened with the March 2013 hard fork in which even a confirmed transaction got double spent).

I'm not talking about these (which deserve their names) but rather about things like this: https://bitcointalk.org/index.php?topic=232979.0 or https://bitcointalk.org/index.php?topic=231309.0 (ie rebroadcasting the same tx with more fees for example, nothing malicious)

But the term double spending is never used (as far as I've seen) when referring to "replace by fee" capability:

They also had a bank account in Deleware in which funds were seized if I remember correctly.

Update: Wells Fargo, a/c# 7657841313

Quote
On May 9, 2013, the Honorable Stephanie A. Gallagher issued a seizure warrant for the
contents of the Mutum Sigillurn LLC account at Wells Fargo, based on the foregoing
information. Bank records also show that nearly all of the activity in that Wells Fargo account
consists of wires between that account and Dwolla, which represent bitcoin transactions for
customers. The other transactions in this account are not significant in number or amounts.

my client says "Seen by 1 node".

What client?

If you are using the Bitcoin-Qt/bitcoind client make sure it is left running and has established connections so that it can re-broadcast the transaction.

396  Bitcoin / Bitcoin Discussion / Re: using tails OS on usb as a secure hardware wallet? on: August 18, 2013, 02:45:31 AM
can this be used as a safe secure hardware wallet?
for example store the private key along on the tails usb
boot, create a simple new blockchain.info wallet,
add private key sign transactions, sweep private key from blockchain.info wallet that was just created,
eject usb reboot system,

can something other then blockchain.info be used with tails to sign transactions?

397  Bitcoin / Press / Re: 2013-08-17 Coindesk.com - Bitcoin Law: What US businesses need to know on: August 18, 2013, 02:25:23 AM
Basically, everywhere except for the United States.

Speeding is illegal on the roads within the U.S. yet the average speeds often exceed the posted limit.  Marijuana is illegal to possess, per federal law, yet a visitor to a city could likely find a source and acquire some in a matter of minutes.

But few people would go thirty miles over the speed limit without expecting a run-in with the law.

The point is, bitcoin has a future in the U.S. even if exchanges are regulated out of existence.

Bitcoin Law: What US businesses need to know
by Marco Santori  [Chairman of the Bitcoin Foundation’s Regulatory Affairs Committee]

This is a basic primer on the state of US law as it applies to digital currency entrepreneurs.

Quote
If the last few months have taught us anything, it is that there will soon exist a new and evolving body of law: The Law of Digital Currency, or, as some would prefer it: Bitcoin Law.
-
[...] 'virtual currency' is something of a loaded term, and bitcoin may not even be best described as a currency at all.
-
[In addition to regulators FinCEN and the SEC, the] consensus among legal professionals is that two more government agencies might soon have a hand in the market as well: the Commodity Futures Trading Commission (CFTC) and the Consumer Financial Protection Bureau (CFPB).
-
Some have called [FinCEN's issuance of guidance] bitcoin’s 'watershed moment' because of its clear, unequivocal positive message: bitcoin is not illegal. The negative consequence, though, was just as obvious: Many bitcoin businesses models are illegal.
-
In effect, the [Bank Secrecy Act (BSA)] deputizes financial institutions, requiring them to act as the government’s foot soldiers in its war on money laundering.
