        In order to run a P2Pool, we need to make a Python module. Step by step.

        So would that be the next step in the process of shifting algo’s?

          My opinion: build the pool module for neoscrypt and then build modules for cgminer and bfgminer, if it’s not posible to do all this in parallel.

          Then test the new versions on the testnet, as we did for the last hard fork.

          If we are really really sure, that everything works as expected make the fork on the prod net.

              The next step is Beta 2 with the near final C code and SSE2 assembly optimisations where necessary. AVX may improve the performance a bit more, but it isn’t of a key importance.

                    This! And I’m actually serious! :o They will ship my cute 1MH today so I will be able to mine the FIRST ftc myself if this algo hasn’t changed by the time it arrives.

                      Beta 1 is ready.

                      Two days later on Cryptsy…

                      1z5i7fk.jpg

                      As I see it, the announcement was enough to shake the market!

                      (sorry for the big pic don’t know how to resize the with the bbcode of the forum)

                              Just reading this: re: Potential flexibility of Scrypt ASICs to modification

                              ,https://bitcointalk.org/index.php?topic=494625.0

                              it seems the GridSeed GC3355 - (Scrypt) ASIC has GNU/Linux onboard, so is programmable anything but the SHA256 hashing algorithm will soon be ASIC mixable, able by adjusting the software… + you could probably even add other op systems.

                              1 - Start the controller in failsafe mode:

                              2 - Telnet into the device:

                              3 - Switch to the live partition:

                              4 - Change the root password:

                              5 - Enable SSH:

                              6 - Reboot the device:

                                Sooner or later, someone will code the other algorithms to run on them, hence why most only claim to be “asic resistant”

                                Nice article though, bookmarked, will have a read proper later :)

                                  Beta 2 is ready. All reference code is in place. 64-bit assembly code is also there, though it works well for the Intel CPUs only. The AMD CPUs are better with the reference code, though I have tested the K8 and K10 generations only. Working on the environment now.

                                    Can you create a p2p test pool ? We can test together. In addition, we need a new mining software.

                                      Ghost let me know if/when you want to test on GPUs, I don’t have any problems pointing my 30+ GPUs at a test coin so long as you have a linux build.

                                        P2pool test pool should be no problem ;)

                                        for the mining software, it’s probably ‘just’ a modification of an existing miner, e.g. cgminer or bfgminer for linux.

                                          If any of you wants to help with either Python code for P2Pool or PHP code for MPOS or OpenCL kernel for [cg,sg,bfg]miner, I have no problem of sharing the reference code with you. I’m going to finish CPUminer first.

                                          P.S. My notebook has blown up yesterday due to summer heat. Shouldn’t have purchased Alienware, lesson learnt.

                                            Probably I’ll be avaliable for MPOS in one week from now. After that I can jump into p2pool if no one else is interested :)
