Optiminer did a lot of work incorporating his optimizations in the wallet. Unfortunately the wallet with his optimizations crashes on Windows at the outset of mining and I don't have any reports of it working on Linux.

Optiminer appears to have abandoned the attempt. So unless Optiminer objects, if anybody wants to try building on his work, I think it would be fair to split the bounty (20,000 HODL). I think getting it working on Linux 64 bit and Windows 64 platforms would be sufficient.

Here's the pull request -
https://github.com/HOdlcoin/HOdlcoin/pull/84

and the repo with the optimizations -
https://github.com/Optiminer/HOdlcoin/tree/2.0

Actually, the correct repo to use if someone would like to build upon optiminers work is https://github.com/Fuzzbawls/HOdlcoin/tree/2016_Miner_Improvements

His original work was based off some older code and I had to do a lot of rebasing to bring it up to current
