this is sick. i've been wanting to learn how to obtain .onions tor addresses i too wouldn't mind throwing in

I've just edited the post; here's a donation address: 1E82DM9mxvvfMfVAwpDANbkwXc2uWvQD1. I hope the original authors of this thread show up at some point as well. I've just tested on a 5770 - about 600MH/s.
Heh, couldn't find the right vanity address then?
ist it possible to create a web service for this so one could attach FPGA and let them calculate?
or use fpga instead of GPU ?
or use fpga instead of GPU ?
nb - are there any simple tutorials that can light me the path to gpu coding easily?
I'm not sure if there are any good top to bottom tutorials. We learned it through projects and documentation. In general, we simplify the GPU code as much as possible, both to make it fast and to avoid branches, loops, etc. Pick your favorite language, find OpenCL bindings, and run some Hello World tutorial. Then pick a project that's embarrassingly parallel (hash searches, noise generation, etc) - each result has no dependence on its neighbor. Read the documentation and pay attention to the memory model. There are a lot of hidden gotchas that can dramatically reduce your performance if you miss them. 
hope you get your bounties.

thanks!

I'd like to announce Scallion, my OpenCL vanity .onion address generator. It gets around 600MH/s on a 6870, allowing it to generate an 8-character prefix in just 15 minutes on average. It's written in C# and runs in both Linux (on Mono) and Windows.
Features:
1) Blindingly fast - 600MH/s vs. 2MH/s for shallot
2) Performs PKCS #1 v2.1 sanity checks via openssl's RSA_check_key function
3) FOSS - MIT licence
4) Support for 1024, 2048, or 4096 bit keys
5) Estimates time required to generate a key (on average)
Check out the Github page: http://www.github.com/lachesis/scallion
or skip straight to the binaries: https://github.com/downloads/lachesis/scallion/scallion-v0.9.zip
If you have any problems, reply to this thread or open an issue on github.

Nice work on this! is there a donation address? I would like to send one.

@OP is the point of this so you can get the priv key to existing onion addresses?
This would be cool
they probably used an i7 six core 4ghz
I was able to hash an 8 character onion the other day with a AMD 3.6 Black Edition Quad Core in Under 48 hours - I have a feeling luck had a little bit to do with it though
and as far as a bounty I would donate 5 BTC to this
thanks
My offer still stands, does anyone else want to offer a bounty as well?
they probably used an i7 six core 4ghz
likely with a program named shallot and a really fast cpu and some patience
a vanity onion with 8 specific characters like silkroad take approximately 25 days to hash on a 1.5 ghz cpu
Time to Generate a .onion with a Given Number of Initial Characters on a 1.5Ghz Processor
|=======================================
|characters | time to generate (approx.)
| 1 | less than 1 second
| 2 | less than 1 second
| 3 | less than 1 second
| 4 | 2 seconds
| 5 | 1 minute
| 6 | 30 minutes
| 7 | 1 day
| 8 | 25 days
| 9 | 2.5 years
| 10 | 40 years
| 11 | 640 years
| 12 | 10 millenia
| 13 | 160 millenia
| 14 | 2.6 million years

cool idea, how did silk road make their onion address?
ive been looking for the same thing
shallot is awesome but its cpu only
so it takes like a month + to generate 8 characters of vanity
any longer than 8 is basically impossible (well implausible time wise)
again this is for generating vanity .onion addresses for the tor network not for bitcoin addresses

Perhaps I've misunderstood this post, I am interested in being able to generate vanity .onion domain hashes using a gpu - hence the modification to the shallot program.
yea it's exactly like vanitygen except it generates .onion addresses
iirc vanitygen is also cpu only based? it would be nice to see both of these ported to gpu based

I was under the impression that vanitygen already generated addresses using gpu's opposed to cpu's, and it still take forever to find a long name. If that's not the case, then how hard would it be for vanitygen to be gpu based?

I'll offer a 10 btc bounty for what the OP described, for a modification to the shallot program to take advantage of a gpu. Payable upfront to a trustworthy member of this forum.
