This sounds interesting, but then the supply of yacoin would be unlimited, right? Why did Bitcoin restrict itself to 21 million?

Nice idea. What is the starting difficulty going to be?
I'm really confused here. People kicked up a big fuss about BitBar's starting difficulty (even though it was no different to a lot of other coin launches) and now a new coin is launching no-one cares about the starting difficulty? I notice Substrata isn't asking about this in this thread which is amusing to me since half of his 70 odd posts must be about BitBar's difficulty level lol |

Same principles apply - you have server farm and botnet owners waiting to unleash 1000s of CPUs on this thing. |

BitBar seems like it's unfairly enriching those who were poised to mine in the first hour or so, due to the extremely low (0?) starting difficulty. Same with Feathercoin and most other altcoins. If N is reasonable and difficulty is reasonable to start, everyone gets a similar chance of enjoying the kickoff. |

Generally yes but I'm not sure botnets will manage to make a damage GPU farms are able to do in minutes it's released. And as I sad earlier I'd rather them to make it than those that own 1000's bitcoins, litecoins and each other coin that appeared, few asics and yet jump on each new one. |

Hopefully though they all have those terrible cpu's that suck zero watts but have actually almost zero power. A few good oc i7 or i5 like most gamers have will be the equiv of 10 of those each at least. |

I'm clearly missing something here. Is it really that hard to increase the N in a gpu-miner source? as the opencl is compiled into gpu-edible bytecode by the client, shouldnt it just take few modifications in the code?
Or is the value of N so much bigger? If so, how are the CPUs going to take it? take a look at the scrypt whitepaper here [http://www.tarsnap.com/scrypt/scrypt.pdf] - looks like a upper bound of a for-loop and that's it?

scrypt(N,1,1) means no current miner software will work. Are you gonna release a patch miner? Are you gonna tweak it so your own version is so much better?

i assume he's gonna change N on the fly. No current miner have an adjustable N, let alone on the fly by some new field in getblock() scrypt(N,1,1) means no current miner software will work. Are you gonna release a patch miner? Are you gonna tweak it so your own version is so much better?

If no current miner software will work, how will we mine it? I'm excited by this, I like coins that offer something new. |

yeah, that was my question - isn't it like 5 rows to change? i hoped that the author or someone with more knowledge on the subject would chime in, i've never written anything in CUDA/CL and if the miner itself verifies the hash(es) returned from the gpu, the it would take a few tweaks there also. (actually, even if there is verification in application that deals with the data returned from GPU, i think there should be a miner with the possibility to skip the checks - if a win7 pc can host up to 8 GPUs, it should be easier to just submit the results than to recheck them before sending. maybe the miners don't do any kind of verification, i'm not familiar with the subject at hand)

I'm excited by this, I like coins that offer something new. i hear you will simply click mine inside the wallet, not sure if you even need to make a conf file for it or not. Hopefully at launch will say exactly what to do. If its just open wallet and click mine a lot more people will probably use it. |

Another thing to note is that changing N changes the amount of memory required. This will (eventually) make gpu mining not worthwhile and much less efficient than cpu mining. ASICs and FPGAs (in their current renditions) won't even come close. This will be a coin ruled by fast memory, and lots of it.

When the source code is posted, you can check what changed in the miner code and make the changes to the cgminer source yourself. |

how do we know he doesn't already have a GPU miner?

This is one of the reasons why I asked for a pre-release source code to check on release what has changed. The manic rush when this coin goes online will be about as transparent as lead. .b |

exactly. and you know what the best part is? if the N is smaller than 1024 as it is at the moment, the hashrate goes up -> 512 => 2x faster, 256 => 4x faster etc. be prepared for lightning-fast scrypt hashrates. (or slow. extremely slow  ) edit: tested it out, 512 gave 500khash on my 6870 (usually 250) on n=512. |
