$100 available to assist with transaction ID problem

Hi,

We're in the final stages of implementing X11 mining in our system, which will allow us to mine and pay out in DASH. Unfortunately, we're run into a problem where the transaction IDs the DASH client is generating don't match the ones our software is generating, and 70 hours of investigation has yet to reveal a solution.

Unfortunately, I can't post a link here, since it states that you need to have 3 posts in order to do so. A full description of the problem and how to claim payment for anyone who might know the answer is available in the "development" section of the Prohashing forums, which can be found by searching on Google.

Thanks for anyone who can help!

Updated: the issue has been resolved. No further help is needed and the reward has been claimed.

Wow, that was fast! I spent days on this and thought I might be stuck for another two weekends. This may be the best money I've ever spent.

I need to go to sleep right now, but when I get up in about eight hours, I'll try this out and make sure you get paid once I get the server working. Talk to you tomorrow!

Thanks! This is the correct answer, and I resolved the issue.

I posted what caused this problem in the linked thread, thanked everyone for their help, and described how you can get paid for your work. I also made a suggestion as to how DASH can be improved to prevent this from happening in the future.

This is amazing service here.
