Title: Can someone write me this program? Post by: Remember remember the 5th of November on September 08, 2011, 01:58:07 AM I am willing to pay 1 bitcoin(max) to someone who writes me a program which will read the blockchain and export ALL the bitcoin wallet addresses ever used in the blockchain to a text file.
When i say every bitcoin address i mean the unique ones I.E no dupes at all. The program must be able to dump addresses to a new file once the other has reached X size in megabytes. Anyone up to the task? Program can be anything, python blah blah, but it must work on windows and source must be provided so i can verify there is no..malicious code in there.

Let me know if that's ever in your price range. Title: Re: Can someone write me this program?

I'm tempted... Title: Re: Can someone write me this program? Post by: Richard Rahl on September 08, 2011, 03:38:44 AM so i can pretend to verify there is no..malicious code in there. Fixed that for you. Raise it to 5 BTC and you might get some serious offers, since this is not a hard program to create at all. $7 isn't even worth opening Notepad.

Raise it to 5 BTC and you might get some serious offers, since this is not a hard program to create at all. $7 isn't even worth opening Notepad. Especially since it can be in some pretty easy languages, hardest part is hooking up the database reading. I agree though, gotta be 5-10 to even get a decent offer on it, 10+ to get a higher quality one thats more efficient in a reasonable time. Title: Re: Can someone write me this program? Post by: etotheipi on September 09, 2011, 03:37:07 AM You want addresses, as in "1Gffm7LKXcNFPrtxy6yF4JBoe5rVka4sn1"? Public keys too? I can give you (BtcAddr, PubKeyIfItExists).
I already have a script that extracts every Block and Tx hash in the blk0001.dat file, so it shouldn't be too hard to do this. But I agree, it's worth more than 1 BTC. I'll do it for 3. Title: Re: Can someone write me this program? Post by: etotheipi on September 09, 2011, 03:45:32 AM P.S. -- I forgot to mention that, to extract all the Tx/Block hashes takes about 5 minutes, so I would expect about the same for pulling out the addresses.
What I have done, though, is to save the blk0001.dat location in a separate file, and then only scan whatever parts of the blockchain have changed since you last ran the script. It takes 5 minutes on the first run, and runs instantaneously after that. If this isn't sufficient, let me know so I can stop here. It's python... so there's not a good way to speed it up.

i'm sure there must be one, i just can't figure out what it is yet. Title: Re: Can someone write me this program?

Title: Re: Can someone write me this program? Post by: etotheipi on September 11, 2011, 01:47:55 PM I got this working in Python, tested on a blockchain file that was about 1 week old. The script took 5.8 minutes to run, and output a 53 MB file with 1,510,680 addresses. I have verified that all addresses in the file are unique. You can download the list from my Dropbox at this link (http://dl.dropbox.com/u/1139081/addrlist.txt).
So I am providing the address list for free, but I request a 3 BTC bounty for the script that generated it. If you want a "smart" script, that only searches the parts of the blockchain that have been added since last time, I'll have to do a little extra work, and ask another 4 BTC for that. I didn't do it already, because it's extra work, and I suspect that a 6-min runtime is probably, actually okay. -Eto EDIT: I just noticed that clicking the link above causes it to load the 1.5 million addresses in the browser.
