Will this actually be able to discover any new prime numbers? The paper suggests to me that it won't but I could be wrong. Since its proof-of-work is less secure than Bitcoin it's pretty pointless otherwise.

I'm curious about this myself... What is the scientific value eluded to in the paper and forum topic subject? I agree, it doesn't sound like this is doing any actual prime number discovery.

Here's the paper: http://ppcoin.org/static/primecoin-paper.pdf

@Philogus

Yes I know there is 1 block / minute on the network. I was interested in, if it would be possible to calculate the average time to find a block, with X primespersec, for single miners, not for the complete network

I see. I think that it would constantly change because the total network hashrate is constantly changing. However, we could calculate a formula that would give you your average time to find a block for one instant in time given your current primespersec. The formula would look something like this:

T = K(N/L)

T= the average time (in minutes) to find a block on our computer system for a given instant in time.
K = some constant.
N = the total network hashrate for a given instant in time.
L = your local hashrate for a given instant in time.

As more people mine for longer periods of time, the value of K should become apparent.

I see, so N would be something like the difficulty I guess

I have 40.78 XPM. How much do you have? DId I just get really lucky here? o_o

Got the same as you, on my laptop.

Looks like it's going to take 2-3 days for that first block to mature.

Is there anything I'm doing wrong?
I go into the debug console and type:
setgenerate true 1

then I type
getprimespersec
and it is 0

but typing getgenerate
outputs true

using "setgenerate true 1" means you're limited to a single CPU core, but if that's what you want it's fine. -1 instead of 1, or just leaving it blank altogether will use all CPU cores.

as for primespersec being 0... not sure, what sort of CPU are you mining on?

ill hopefully modify it to get the prime's network hash .etc just need to find out about the block structure

Color me incompetent, but how do I build the primecoin-qt client (on ubuntu linux)?
primecoind is all nice and dandy, but having a graphical client would be nice...

Onkel Paul

The file that you downloaded was primecoin-0.1.0-linux.tar.gz. When you extracted it, you got primecoin-0.1.0-linux. Inside that folder is a folder called "bin". Inside bin, there are two folders, "32" and "64". Pick the one that matches your cpu (32 bit or 64 bit). Inside that folder, you'll see primecoind and primecoin-qt. If you want to run the graphical client, just click on primecoin-qt. I hope that this helps! I'm running it now getting 31 primespersec on my Toshiba L675 laptop running Fedora 18.

block explorers up but i can already see its going to need some modifications.

Yea got some data out of it..

I mined the genesis block

is it worth more? Wink

It is already built. Just click on primecoin-qt in the primecoin folder.
