      Step by Step ,

      I had compily cgminer 3.6.6 with neoscrypt on MinGW. I set --enable-neoscrypt , Compile support for neoscrypt feathercoin mining.

      I get cgminer-neoscrypt.o and cgminer.exe .

      Next, there is still a very large number of hard work. Wish me good luck.

          We have not an OpenCL kernel, there is still a very hard work.

              Is there someone official behind the ccminer? That’s also a viable option for nvidia and perhaps he/she/they have more time to add NS? :)

              yes ccminer is the second miner for NVIDIA cards.

              I have no contact there, but will check on Github, if there is a contact email. Otherwise I’l lcreate a feature request.

              Question: can we provide neoscrypt code to the programmer of ccminer and cudaminer, or should it remain private for the time beeing?

              -------Edit--------

              The owner of the ccminer repository on Github is the same than for Cudaminer.

              I think the answer ill be the same: yes, but not very soon…

                Yes if they agree to keep it confidential until the official public release. On the other hand, if they say “yes, but not very soon”, they get the code after the public release anyway.

                  Sorry for the post, but are there any links to what Neo is about or are you guys trying to develop it from a bastardisation of blake or something?

                  What are the main benefits we can look forward too for GPU mining or not 100% on stats yet? (other than maybe lower power and asic _resistance _short term)

                    It is what Scrypt has been used to be: memory intensive, ASIC resistant, more secure. It isn’t a bastardisation of anything. The complete specification will be in the press release.

                      I will hold back the code until the official public release

                        Time is running out. We need to be completed within 10 days.

                          There is a small yet annoying bug left in the switch process. Once eliminated, I set up a testnet with a couple of P2Pools. NeoScrypt itself is fine.

                            Which profile will be used?

                            Or is that not finally defined?

                                  After launching NeoScrypt, a marketing campaign is necessary to get the world know.

                                  Reshuffling the webpage can be considered as a great progress.

                                  Here are some good examples–

                                  http://www.nxt.org/

                                    Profile zero. The other ones are for testing or compatibility.

                                        I think the website already looks pretty slick. I think we will get a lot of exposure from the launch of the new algo!

                                          The bug I’ve spotted recently is that CreateNewBlock() may segfault client under certain circumstances which can be reproduced. While it may be unrelated to NeoScrypt in general as I haven’t changed anything related to block structure, it is an important security issue which needs to be tracked down.

                                            This is a great thread and completely nessecary discussion.

                                            I worry that the whole thing could be controlled by a handful of big farms and that somehow the big money players forsaw this all along? Even planned it? If it is not decentralized then I am back to real commodities I can hold in my hand.

                                            With that said I think it needs to be kept in mind that ASIC mining is way more energy efficient. If we fight ASIC we kill the efficiency level of mining, large scale or small, it still requires electricity. I was mining using (2) 7950 GPU’s burning 550 watts at the wall to produce 1.2Mhs, switched to a ASIC for Scrypt miner burning 12 watts and producing the same or greater hashing power with way less space, heat, cost, noise, and setup hassles.

                                            The focus needs to be on decentralization for sure, but effeciency needs to be a high priority or people won’t add miners to the network.

                                            My two cents worth
