201  Bitcoin / Bitcoin Discussion / Re: Playing with Public Keys on: July 24, 2012, 03:39:36 AM
This concept is usually known as "brain wallets".

I recently played around with this myself and found that SHA-256("test") has been used: http://blockchain.info/address/1HKqKTMpBTZZ8H5zcqYEWYBaaWELrDEXeE

BTW, the variable you named "sha_pubkey" actually contains the Bitcoin private key, so you should rename that one. Smiley
202  Bitcoin / Development & Technical Discussion / Re: Proposal 1:10 split, every block reward halves. on: July 22, 2012, 05:19:05 AM
We are already seeing millibits (mBTCs) being used as the unit more and more.

e.g., http://Bitzino.com and http://www.Ogrr.com both use mBTC exclusively.    Others will follow.

Seals with Clubs also uses mBTC (referred to as "chips").

Is there any reason Blockchain.info should continue displaying a QR code that contains a broken URI?

Because bitcoin: would not work with some of the social media share links, I think Facebook and G+ would accept bitcoin:// links but not bitcoin:

Why on earth would you share a naked bitcoin: URI on Facebook? Surely it would be the web page containg the payment link that would be shared. Anyway, I don't think you should output broken URIs because of this. Remember Postel's law: "be conservative in what you send, liberal in what you accept".

If Facebook is broken then a bug report should be sent to them, we shouldn't break the rest of the Internet because of it.

Version 0.19 seems to always crash when using the -X option.

Code:
% ./vanitygen -X
Segmentation fault

Looks like something's wrong... "Time Since Last Block: 5 Hours 42 Minutes", and the shares stats aren't updating.
207  Economy / Web Wallets / Re: Blockchain.info - Bitcoin Block explorer & Currency Statistics on: July 11, 2012, 01:55:59 PM
I noticed a bug in the balance graphs, the balance goes to zero after the last transaction. Example: https://blockchain.info/charts/balance?address=1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa

Also, when I hover over the "archive address" icon, half of the popup text is outside the window and can't be read. (Browser: Google Chrome.)

Anyway, My Wallet is great, and the speed of development is quite fantastic. Keep up the good work! Grin
208  Bitcoin / Bitcoin Discussion / Re: FirstBits.com - remember and share Bitcoin addresses on: July 10, 2012, 01:48:17 PM
A couple of bug reports for firstbits.com:

1.

The email address listed on the site doesn't work:

Quote
<webmaster@firstbits.com>: connect to firstbits.com[108.171.201.215]:25: Connection refused

2. (What I tried to email to you.)

When I enter the address from the genesis block (1A1zP1eP5QGefi2DMPTfTL5SLmv7DivfNa), firstbits.com prints:

Quote
Your firstbits address: %s

The threads in "Alternate cryptocurrencies" are now about 75% Litecoin. Is it time to create a dedicated child board?

211  Bitcoin / Bitcoin Discussion / Re: How Do I Encrypt a Paper Wallet from bitaddress.org? on: July 09, 2012, 05:21:23 PM
Using GPG is clunky because it is intended for asynchronous encryption.  It can be used but if you lose the key then you lose the coins.  You could print the key and store it with the cipher text but then your security becomes only the passphrase. 

Uh, no. gpg -c does symmetric encryption. It does not use a private key.

I would use AES.

gpg -ac --cipher-algo aes
212  Bitcoin / Bitcoin Discussion / Re: Coin generation participation survey on: July 03, 2012, 03:05:55 PM
1) Have you been using bitcoin for more than two months?
Yes, almost 3 months now.
This confused me greatly until I noticed the date... Smiley
Holy thread necrophilia, Batman!
213  Bitcoin / Bitcoin Discussion / Re: Why not adjust the block reward on every retarget? on: July 01, 2012, 02:07:31 AM
A right bit-shift always guarantees that the output is smaller than the input.  Because of this, when the reward is 1 satoshi:

0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0001

and it is time to lower it further, the code will perform a right bit-shift on that value, which will result in a reward of zero:

0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000 0000

Thus, no more Bitcoins will ever be generated. This is no mistake. Satoshi knew what he was doing.

...and in case anyone is wondering, this will happen approximately in the year 2140.

So I tried this out today. I bet, won, and got half my stake back. WTF!? Angry

http://satoshidice.com/full.php?tx=c32408f4fd9b54722d44ceb030e8439ef015730e8bcddcf9396d396e6399f7c6


Bet Amount: 0.00100000
Win multiplier: 1.009
TX Fee: 0.0005
Final amount: 0.000509

And then there is the tx fee you paid to send the bet.

We really need to raise the min bet.  With the transaction fees they don't make much sense for anyone.
Oh, so the customer has to pay your transaction fees? It would be nice if you would disclose this on your web page...
Also, the tx fee is not mentioned at all on the details page (full.php).

Nice uptick in downloads: http://sourceforge.net/projects/bitcoin/files/stats/timeline

It's only 7 am in the Pacific timezone and today is already the best day this year for downloads
217  Economy / Speculation / Re: $6 today?! on: January 05, 2012, 01:53:53 AM
I think we will hit 100 in the middle of the year and then another correction that make the media say that bitcoin died...

If we extrapolate today's data, we should be at $371, this time next year.  Wink
218  Bitcoin / Bitcoin Discussion / Happy birthday! on: January 04, 2012, 12:35:31 AM
The genesis block was created January 3rd, 2009, so the Bitcoin block chain is now 3 years old! Happy birthday! Grin

You can't do the second hash with a string as input, you need to use a number. In this case the number is 0x2cf24dba5fb0a30e26e83b2ac5b9e29e1b161e5c1fa7425e73043362938b9824.

Just noticed, a quick credit edit



I am not sure why someone would want to advertise using a quote from Wikipedia as the source for anything, when the actual source is better.

This "Part" is aimed to change with time, also, while I agree that BitcoinCharts is a nice choice as well, Wikipedia is here used for its "neutrality" toward Bitcoin.
Wikipedia is not a reliable source. Quoting it on the front page looks very unprofessional.
If someone edits the article and adds "Mt. Gox sucks balls", will you quote that too? Tongue
