Developer ist the only one with GPU-Miner from the start (just joking hopefully)

Will keep an eye on it

Good luck

hm......thats a serious problem and  the coin would definitely be dead if it occurs

ppl will lose trust about the cpu-coin......

Hi Guy,
I want to consult with all of you about N-factor.

I have tried with N-factor = 14, N = 32768 in Intel(R) Core(TM) i5-3320M CPU @ 2.60GHz. Result is segmentation fault.
I tried to change it to N-factor = 4, N = 32. it is working normally.

My question is what is begining of N-factor should we pickup for Vertcoin. I want to prevent GPUs and ASICs, but when I choose N = 32768, it prevents CPUs too.

Nfactor   N   Memory
4           32   4 kB
5           64   8 kB
6           128   16 kB
7           256   32 kB
8           512   64 kB
9           1024   128 kB <--- Current Litecoin using.
10           2048   256 kB
11           4096   512 kB
12           8192   1 MB
13           16384   2 MB
14           32768   4 MB <-- My Core i5 cannot mine already.
15           65536   8 MB
16           131072   16 MB

Sounds great.

Don't aim to prevent GPU mining..  If you can keep out the ASICs you've still done us all a great service, and it'll take time for the GPU miners to catch up since cgminer is unsupported for scrypt.

I'm still thinking about that. Or Should I just start at N = 2048, then let's change N every 8 - 12 months for preventing ASICs but still give opportunities for GPUs to catch up ?

Does this use scrypt-jane?

Nope, I'm using scrypt like Litecoin but change N from 1024 to (... don't know yet .. please vote ...) and the N will change base on timestamp like Feb 2015 will go up, Augest 2015 will go up again. Not scrypt-jane.

How much physical memory do you have on the i-5 that segmentation faulted?

Does N-Factor=12 or N-Factor=13 work properly?

I tested with N-Factor=4, 9 and 10. it works normally. Right now still testing with N-Factor = 12.

I am testing on VM. My VM has RAM 8 GB. My laptop has 16 GB.

I say start with 11.  Don't set a specific date for moving to 12+, just do a forced update for the client at a specific block when it looks like ASICs are going to catch up.

YACoin is at an N-factor of 14 already and they don't have any problems with scrypt-jane.

I would guess there is something else wrong, as an i5 should be able to manage 4MB of ram without problems.  Don't know what Scrypt-Adaptive-Nfactor is though.

Try one of the YAC miners from here, and see if it works:  http://yacointalk.com/index.php?topic=264.0

ready for a botnet attack? it will almost kill da cpu-coin

We have 3 servers located in LA, NY, and Amsterdam. Hope, that's will be enough to handle otherwise we need to seek funding for other servers.
