Cpu mining
Traderman was asking about the status of the CPU Mining release (which does contain the heartbleed fix).

We've been working hard on the cpu miner version, focusing on testing it properly for the last 3 weeks, and we are running a little behind schedule due to a few technical problems.

However, I would like to announce this version is better than we expected, including new features that were only possible to be included while the body was on the O/R table.

For example, we added ASIC resistance, requiring GPU miners to post boinc CPIDs/RAC/Project Name/BoincAuthkeys along with getwork() requests, thereby forcing our miners to run boinc.  Also, we added in CPU PoB algo resistance to slow down the ability to port the Cpu miner code to a GPU.  We did that by adding in a brand new algo to the coin:  AES512 encrypted blockhashes.  Since each CPU hash must make a round trip after being skein hashed, then AES encrypted, it will be much harder to port AES to a GPU due to the large code footprint and business logic requirements to shift the RAC inside the Skeinhash to the proper positions in order to test the validity of the AES hash.

The code is now 95% tested, and we are in the burn-in phase.  I envision testing for a few more days, and then as we get closer to the weekend, announcing the exact block number for cutover and date to allow the exchanges to be ready to switch.  If I were to take a guess, I would say within 7 days.

Best Regards,
