[XPM] [ANN] Primecoin Release - First Scientific Computing Cryptocurrency

[Zalfrin]

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?

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

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

Got the same as you, on my laptop.

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.

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'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

Still at 0 XPM

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

Ok I see that's what I get for trying to build from the github source... As you explained later, the tar file contains a pre-built binary, so I'll probably switch to that.
With the sources, I managed to build the primecoind and get it running (it's mining, but no luck yet).
I probably need to perform some qmake trickery to build the GUI...

Yes, N should be directly proportional to difficulty. You could also use the total network hashrate (this might be the wrong term, I guess it would be the total network primerate). The only diffence between using the two would the the units that the constant is represented in.

Holy crap, mining for 2,5 hours on 4-core phenom = 0 coins.

[ReCat]

Very dependant on luck it seems. A pool would distribute this luck more evenly/fairly.

[Remember remember the 5th of November]

Holy crap, mining for 2,5 hours on 4-core phenom = 0 coins.

Same man...nothing on my Phenom II 955 x4 and nothing even with all cores for hours.

[PoolMinor]

Holy crap, mining for 2,5 hours on 4-core phenom = 0 coins.

Same here only FX8120 = 0 coins.

This coin is going to be really rough on the 1 CPU owners. No non-client miner so no pools. =/

@irritant...This proves that the average time to find a block really is almost completely random. It is very much like a lottery, you could find a block in 10 seconds or 10 years. We could calculate the most probable amount of time that it would take you to find a block for given network conditions, but that time could be VERY far off from what you actually get.

Mining since launch with my i7-3820 and still nothing...

I will buy your xpm, if you want to sell shoot me a pm with how much so I can offer you a price in ltc.

[craslovell]

got my first block - an AMD CPU did it
