Nope, it just goes to a blank page atm like it's stuck or something

Wow, that's the most annoying sig I've seen. Welcome to /ignore.

Ah thanks, but how can I add the 2 private keys together to get the one for 1PepsiCosowjScTRFjSUvpgnEeEfC5Xbi

Edit - Ah I see that you'll said you would fix that on your site, np & no rush, I'll do it then

I think that if you add the private keys, it should work fine. The problem only appears to affect that public key at the moment. If you combine the private keys, you should get a proper private key you can import and so forth.

opps, sorry I messed up, they are all fine - my mistake, just the 1PepsiCo one that is shown solved but the solution doesn't work, could you reenter it to be solved again, many thanks.

Actually, the solution works, it's just that my GoBitTest website appears to have some problems with it. Given the private key:
4876652DE4D45277999C7C02C5E8EB0CEF7A512CB4AE7EF51A85ED2D1996A629

it prints:
049322AA20CA83131F635C7ACBB05484E3FEDEAC699DF6FF34AEFDFEFEF4EEFFAEC10A698CC2DF6 DD9A9B95175C7C4416132F03771C21EC9DFF824FA5F7630B5

Using https://www.bitaddress.org/ we get:
049322AA20CA83131F635C7ACBB05484E3FEDEAC699DF6FF34AEFDFEFEF4EEFFAE00C10A698CC2DF6DD9A9B95175C7C4416132F03771C21EC9DFF824FA5F7630B5

So my test suite doesn't print that first zero byte for one of the points. I will look into fixing it soon.

Adding your public key, we get the solution of:
1PepsiCosowjScTRFjSUvpgnEeEfC5Xbi

Sorry about the inconvenience.

seems to be broken atm, I've received notification of another 2 solved but they don't work to retrieve the solution??

Hmm, so you have received confirmation emails, but the solutions are not present on the pool?

Also note that the sign was in fact wrong on one of those solutions that I posted the other day, I updated the post to have another correct example so they should be safe to check against.

Hmm, sounds promising. Can you point me to some specification of that format, so I can try implementing it?

https://en.bitcoin.it/wiki/Protocol_specification#Signatures gives the public key format.
https://www.bitaddress.org/ will give both uncompressed and compressed addresses on the wallet details tab (that's what I've been using to double-check my results)

It's not base58, it's the compressed address format that the bitcoin client started using in v0.6.  Been working on improving vanitygen performance and added compressed support to vanitypool.thruhere.net for testing but promptly solved all the remaining work there.  Seems you can improve the hash rate by 80-90% pretty easily by checking the compressed addresses as well but it effectively cuts all the bounties here in half if half the solutions get rejected.

ThePiachu, do you have any connection to the following website: http://www.haagediss.com

If not, I would like to let you know that someone is misusing your name.

Thanks for your concern. I have been developing various solutions for this person over the course of a couple months. The server side of this website was one of those. The frontend was done by him, as was the idea.

Yeah, the Pool accepts hex encoded solutions, not base58. I might add that feature in the next version.

Many of my bounties solved today, many thanks, just one that is reported solved but when I try to sum it to get the address & private key nothing happens - the page just goes blank??

The website appears to be working for me. However, my gobit test suite appears to be having some problems, as the private key

4876652DE4D45277999C7C02C5E8EB0CEF7A512CB4AE7EF51A85ED2D1996A629

encodes into

which appears to be one byte short for some odd reason...

However another "educated quest" may be provided for users. Pool can calculate "recommended bounty", which will make mining for this solution a bit more profitable than bitcoin mining. AFAIK there's some simple approximation between (vanity's) GKey and (bitcoin's) MHash, at least for some kind of hardware as ATI HD xxxx. Fizzists's calculator is useful, although it don't take bitcoin profitability in account.

I believe that providing bounties a bit higher than equivalent in bitcoin mining will attach much more attention to all this stuff...

I complete agree with this except I would like to suggest that the bounty forced to a value that will be GPU profitable allowing them to offer more than the minimum profitable bounty to get a higher priority.

Vanity address generation isn't like mining in the sence that some miners may be doing it at a loss simply because they believe strongly in the bitcoin idea and want to help secure the network. This incentive does not exist for vanity address generation so the bounty should be forced to a value that is profitable.

Calculations are a little difficult with highly variable energy costs but I think we could take a global average and use that. Also take an average of efficiency of the top 10 GPUs and use that in the calculations.

Even after GPU mining is not profitable, there is till going to be thousands of gamer enthusiasts which will mine for vanity addresses when they're not gaming. The end of GPU mining certainly does not mean the end of GPUs. I think I read that mining represents only 1% of AMD's sales.

I'm not sure how I can help but I would like to. I have some free time these days.

feedback:

I put a generation request (MoLeCuLaR) with a much too low bounty.
...

I'm sure you know that you can send additional bounty to the same bounty address if you wish to make it more attractive/realistic.

Even better, request another pattern with the same public key with a reasonable bounty and both will be worked on. You can pop in the pattern and your pubkey to my calculator and it will suggest one.

True, it doesn't make sure that this value will be higher than for bitcoin mining. The reason is that I'm still waiting for more data to figure out a reasonable hashrate/keyrate ratio that is valid for most GPUs.

As for estimating the total key/s for the pool, this will probably need some change to the protocol to allow the miner to occasionally report keys generated in the last N seconds. Then, the pool would be able to display this and make some estimates. Of course, this number should vary widely as more valuable work appears. For now, the best we can do is set a bounty that is higher than the rest.

Another option to get a crude estimate: on the completed work page, show timestamps of when the work and solutions were submitted! Also, make the solved work available in an API (JSON please).

I think maybe both these problems could be taken care of by informing the user about the results of some educated guess as to how high the bounty should be on the page where people enter the requests? Maybe a little table based on the given "difficulty" like this:

That would be great. Unfortunately it requires pool to know pool hashrate, which is not possible yet. And it might fluctuate a lot, depends on the highest bounty in the pool.
How about just saying an estimate for how many GKeyHours will be required for 50% probability?  You could also provide how many GKey are currently on the pool.  Is reporting like that currently in oclvanityminer?

Soon most GPUs will be useless for bitcoin mining, so I don't know if providing bounties "a bit higher" will last very long, but I agree that is a good idea for now.
