Is there any indication how long it should take to get soime coins? I.e. after mining x hours at 20000 primespersec you should find a block?
Or is it just totally random? There are people in the richlist that have 100+ coins. How did they manage to do that?

Theoretically you will find a gap with merit m (~difficulty) within e^m prime gaps:

e^20.45 = 760890487, so you will need to calculate about 760890487 primes to find a new block.

If your primes per second are 25000 then you will need 760890487/25000 = 30435 seconds, which are about 8:30 hours.
So you will finde ~ 2.8 blocks per day.

The rpc-call getmininginfo has a new value called gapsperday, which is calculated using the above formula.

I uploaded the Windows wallet to Google Drive for anyone who is experiencing issues downloading or extracting the wallet files. No password is required, just unzip/extract the files and run "gapcoin-qt.exe" !

Almost forgot to mention, Gapcoin has two new RPC calls:

Code:

listbestprimes amount (min merit)

Returns a sorted list of the best prime gap merits.

Arguments:
1. amount        (numeric). number of prime gaps to display
2. merit         (numeric, default = 16). minimum merit to display

Code:

listprimerecords merit

Returns a list of all prime gaps with the given integer merit.

Arguments:
1. merit        (numeric 1,2,3..) the prime gap merit.

Note: The above rpc-calls can take a long time to respond.

Hey j0nn9. I am using some computers mining with gapminer on another computer and it seems to work. So i got 'share found' which as far as i can understand it shoud be block found on the daemon of the other pc. But it seems that i didnt found anything.

So my question is, can gapminer indeed mine on another computer's daemon or i am doing something wrong and i am just wasting the miners power? They seem to get work and mining... Could it just be an orphaned?

Yes, it should be possible to mine with gapminer on another computer.
If gapcoind accepted the block, you should see something like this: "Found Share 20.798565 => accepted"
otherwise: "Found Share 20.798565 => stale!"

When your share (block) was accepted, it can still be orphan.

Hey guys,

First off, this is an awesome coin! I'm having fun trying to find blocks (found 2 so far!)

Question,

Is there any way to tweak the sievesize and sieveprimes from the command line or the config file?

And if there is, what would be some good values to test ?

thanks

You can use the setgenerate rpc call:

Code:

setgenerate generate ( genproclimit ) ( sievesize ) ( sieveprimes ) ( shift )

Set 'generate' true or false to turn generation on or off.
Generation is limited to 'genproclimit' processors, -1 is unlimited.
See the getgenerate call for the current setting.

Arguments:
1. generate         (boolean, required) Set to true to turn on generation, off to turn off.
2. genproclimit     (numeric, optional) Set the processor limit for when generation is on. Can be -1 for unlimited.
                    Note: in -regtest mode, genproclimit controls how many blocks are generated immediately.
3. sievesize        (numeric, optional) Sets the size of the prime sieve.
4. sieveprimes      (numeric, optional) Sets the amount of primes used in the sieve.
5. shift            (numeric, optional) Sets the header shift.
                    Note: sieve size can only have 2^shift size.

Note: shift also should be in range [14, 512]

Shift, should be the most sensitive parameter, because it controls the bit size of the primes.
Second would be sieve primes.

First of all, Gapcoin follows Riecoin's way and uses enough Miller-Rabin tests with random bases to avoid composite numbers being accepted as Prove of Work, like Primecoin mistakenly could.

In Primecoin a fermat liar could be accepted as PoW.

PoW.cpp:

Code:

130   /* start has to be a prime */                                                 
131   if (!mpz_probab_prime_p(mpz_start, 25)) {                                     
132                                                                                 
133     mpz_clear(mpz_start);                                                       
134     return false;                                                               
135   }                                                                             
136                                                                                 
137   mpz_init(mpz_end);                                                            
138   mpz_nextprime(mpz_end, mpz_start);

mpz_nextprime also uses 25 miller rabin test:

mpz/nextprime.c:

Code:

107     /* Miller-Rabin test */                                                     
108     if (mpz_millerrabin (p, 25))                                                
109       goto done;

Every client uses 25 miller rabin test with random bases, to prove the primality of a prime gap.
That should ensure that pseudo primes gets detected by the network.

I'm doing some reading on the three links I found on your website.

Also, looking forward to difficulty 35.4245 Cheesy

Do you have any expectations of what kind of hardware would need to be involved with this in order to get the difficulty to that level?

Probably GPU and/or FPGA miners.

Looking to setup a pool for this, was wondering how to setup the stratum support.

Dev, are you working on any source code for stratum pool support?

Essentially I saw in the original post and on official website that a pool is more friendly to setup for this coin as oppose to RIC or XPM. I thought I read it to be as easy as scrypt, however, being that this coin has its own algo, I doubt the stratum support is there just yet. Just curious how one would go about this.

Thanks in advance!

Yes, a stratum-mining implementation for MPOS pools is in progress.
I will inform you once it's finished.

Thanks, so to start mining with the wallet all we have to do is add setgenerate true?

Yes

Trying to get the RPC miner on to my BAMT miner and am getting this when trying the make all:

Code:

src/PoWCore/src/PoWUtils.h:296: warning: integer constant is too large for ‘long’ type

Uhh, that was a bug within the 32 bit compatibility.
It is fixed now, use git pull.

Code:

src/Miner.cpp: In static member function ‘static void* Miner::miner(void*)’:
src/Miner.cpp:171: error: ‘SCHED_IDLE’ was not declared in this scope
make: *** [src/Miner.o] Error 1

Any idea how to fix this?

you could delete Miner.cpp:170-172

Sorry for that, GapMiner still has alpha qualities!

I'm running the qt, and get this in terminal:

Code:

(gapcoin-qt:11481): Gtk-CRITICAL **: IA__gtk_widget_get_direction: assertion 'GTK_IS_WIDGET (widget)' failed

What's that mean?

QT seems to run fine, but it gives that

Could be a GTK bug?

lol at the block size, 0.07, no point for early adopter...

no surprise mining is dead

lol
I found a block with 0.009 GAP Tongue

Don't worry it will become more, reward is increasing quadratically within the first 1152 blocks.

Source code updated do:

Code:

git pull

if submodule PoWCore doesn't update, try:

Code:

git submodule foreach git pull -u origin master

or:

Code:

git submodule update

Is there GPU miner for that coin .
quiting from official website
"Gapcoin will only be CPU mined until someone releases an GPU or maybe even an FPGA miner. This site will contain detailed instructions to mine Gapcoin, including descriptions for cloud mining. "

Pls inform if someone got GPU miner for GAP coin

Thanks in advance

No, there are currently no GPU miner for Gapcoin.

Hi!

I get error while configure:

Will i be able to mine this coin from wallet itself or i must use the mining software??

Both are possible.

Quote from: Jacksp on October 20, 2014, 08:03:43 AM

What is more profitable, solo mining or RPC mining?

It should theoretically be equal, because Gapcoin and GapMinder using the same PoW / mining code base.
At the end it will depend on your system.
