That font has only uppercase letters, just as used in the movie.


Close but it looks a little different to me.  The R has a straight line while your sample has a curved one. The G's bottom is slightly different too.

It's not just that there are no numbers, but that it is upper case followed by all lower case like a person's name.

Yeah, roughly (24/58)^7 = 0.002 for an uppercase followed by any six lowercase, so its getting on for unlikely, but not wildly impossible.

As you all probably know more about this than me; what about with every second letter a vowel?

Eg  1Nakamo
not 1Stshnm

I think 20/58*6/58*19/58*6/58*19/58*6/58 = .000040965

That's CapitalConsonant + lowercasevowel + lowercaseconsonant + lowercasevowel + lowercaseconsonant + lowercasevowel

The 32-byte hex thing was me just trying to be funny because that's what a private key is.
That was not the OP.

I think from the public address it's obvious this is not a brain wallet.


Ah, sorry.  There's a small chance this is real but I agree the public address is unlikely to have come from brain wallet.

Not to belabor the point but you said...

It's a 32-byte hexadecimal string.

then you also said...

As soon as I typed the last word in thats how the address looked...


Are you saying you typed in words but are giving clues to the sha256 resulting hash (i.e. what brain wallet calls the 'secret exponent') and not the passphrase itself?

If so, then your clues would give hints to each nibble/byte or some other sequence of the sha256 hex string, not the passphrase. (Can you clarify?)

So, for example, clue #3 may refer to 'DEAF'.

That address looks like it was generated with a vanity gen.   Is the "1Natimo" prefix intentional?

If so, I'm skeptical.  The private keys generated by brain wallet are sha256 hashes of a passphrase.  I don't see how you could come up with a passphrase that would generate a 256 bit private key which in turn would generate a public address beginning with "1Natimo".  The pass phrase would just look like random characters and have no meaning.  


6  Bitcoin / Bitcoin Discussion / Re: The $1000 Bitcoin, yes it's worth at least that. on: April 18, 2013, 04:42:35 AM

Have you heard of financial instruments called options? If that's too cumbersome, have you heard of service providers like bitpay?

Bitpay turns bitcoin into a payment processor using the protocol aspect. It matters not what the price of bitcoin is then, does it?  Thanks for making my point.  Bitcoin has little value if not for the USD.  My point is that no vendor in their right mind is going to accept bitcoin as a currency.  It's too volatile.


The only reason gold is above $10 is pure speculation on future value which can't be sustained.


Wrong.  Gold is real, physical, shiny, pretty and has many uses in the real world that determines its price.  Once the world discovers bitcoins are only useful for gambling and illegal substances, it's true value will be discovered.  Which in my opinion is way below $1000.  Let's meet up again in 20 years and see who has won.
7  Bitcoin / Bitcoin Discussion / Re: The $1000 Bitcoin, yes it's worth at least that. on: April 16, 2013, 10:57:09 PM
Agree with tclo

Bitcoin's current utility does not justify a high valuation and volatility makes it a sucky currency. 

If you were a vendor, would you accept bitcoins in exchange for real goods knowing the value can drop 50% overnight?  I wouldn't.  Look at http://bitcoinstore.com.  Prices are simply USD converted to BTC every time you refresh the page.  So any orders taken when price was $270 robbed this vendor big time.

Current utility is based on gambling services, illegal products and a handful of legitimate uses.  The only reason we're above $10 is pure speculation on future value which can't be sustained. 

8  Bitcoin / Bitcoin Discussion / Re: Bitcoin is a “bubble” only if you think the rise of information is a “bubble” on: April 09, 2013, 06:34:22 PM
People..people.  We're talking about a distributed tamper proof transaction ledger.  It has some utility.  The free market will decide the price to get yourself an entry in that ledger in terms of USD, chickens, pigs or whatever.   It can't be compared to 'rise of information'.  Sheesh.

I personally feel the current valuation is not in line with the utility today and it will require more mainstream adoption before it does.  So I'm on the side of bubble.

I think the current price reflects the following components: 1) gambling addicts circumventing USD regulations, 2) legitimate exchange of goods and services, 3) pure speculation on future value.   My gut-feel weighting is 1: 20%, 2: 5%, 3: 75% = bubble.

This comparison to 'rise of information' is pointless.  Markets are bubbles when prices rise because prices are rising.  It never ends well.
9  Bitcoin / Bitcoin Technical Support / Re: Please help! My wallets are trapped on a corrupt HDD! on: April 08, 2013, 03:55:56 AM
Assuming you have only one computer, I'd remove the HD.  Replace it with a new HD and install Ubuntu again.  Now hook up the failing drive as a slave.  After you boot off the new Ubuntu installation, attempt to mount the slave drive's partition that used to hold your wallet under something like /mnt/recover

i.e.

sudo mkdir /mnt/recover
sudo mount -t ext4 /dev/sdb1 /mnt/recover

The parameters will depend on the file system type, drive letter of the slave (bad) drive and partition number.

(You could probably also just boot off of an Ubuntu 12.10 installation CD and then press Cntrl-Alt-F1 to get to a shell.  It's possible to do the above without installing Ubuntu again but since you're going to do it anyway, I'd just install fresh onto a new HD)

If the drive isn't too far gone, you may be able to navigate to the .bitcoin dir in your old home folder and recover the wallet.dat file.

If you don't remember which partition your home dir was on, you can use fdisk to see what's available and just try to mount them all to different dirs you create under /mnt

i.e.

sudo fdisk /dev/sdb
p <enter>

/dev/sda1   *        2048     1953791      975872   83  Linux
/dev/sda2         1953792   158318591    78182400   83  Linux
/dev/sda3       158318592   482537471   162109440   83  Linux
/dev/sda4       482537472   488396799     2929664   82  Linux swap / Solaris

For example, my /home partition is /dev/sda3

If you get failures attempting to mount partitions, you can try sending the raw drive bytes over to a file on your new HD.

i.e.
dd if=/dev/sdb -of /tmp/recover.img

It might be possible to sift through the data to find the wallet.dat header and then your private keys within it (unless it was encrypted)

I believe the price rise is due to the increasing popularity of gambling services.  Don't underestimate the power of the hopelessly addicted members of our society as they buy more and more bitcoins to chase their losses.  We are witnessing the effects of a growing pool of internet gamblers buying into bitcoin to satisfy their addiction.   As long as the pool is growing, the price will keep rising.

I got it working by installing pyopencl from source rather than the apt-package.  The apt-packages are broken on 12.10.

Have you heard about levelling (I'm not sure if that's the correct word, not a native English speaker).

I think the English term for this is 'Dollar cost averaging'. 
14  Other / Beginners & Help / Re: Butterfly Labs on: March 20, 2013, 09:25:25 PM
I don't know if Butterfly Labs is a scam or not but I find it irresponsible to accept so many pre-orders for such a long period of time without actually having a product to ship.  I believe the pictures you see on their website are nothing more than concept art.

Hi.  I am glad to have joined the forum.  I am a sotware engineer working in the San Francisco Bay area.  I mined bitcoins for a while about a year ago and am getting back into it again.  I'm thinking of purchasing an ASIC miner but sounds like it will take months to acquire.
