[ANN][GAP] Gapcoin - Prime Gap Search - New Math Algo - CPU / GPU - Zero Premine

What is the reward now? Is it profitable to use a vps or should one wait for the new reward?

It should be full block in about 120 blocks from now...

hi@all,
my wallet showed up a found block, coins were added. now, a few minutes later, this block isn't in the statistic anymore and the amount of coins decreased?!? it had an amount of 16.xxx gap, now its gone. where are they now???
maybe somebody can explain that to me...

thanks for any answers and good mining

300 min / 60= 5 hours

Probably you were unlucky and mined an orphaned block?

hmm, it's possible. i don't know how an orphaned block "acts" in the wallet  it left not a single trace, just gone. i thought, orphaned blocks have to be confirmed first before they show their ugly face. in this case, time was to short to get confirmed. (last found block ist still pending). thx for your answer, bro! i don't like things like this

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!

j0nn9,

can you please elaborate on this:

With Gapcoin, you will be able to anonymously send money around the globe in no time.

Can you also please elaborate on this:

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.

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

Also, looking forward to difficulty 35.4245

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?

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

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

j0nn9,

Anonymously as in Bitcoin "anonymously" 

Can you also please elaborate on this:

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

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.

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.

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.

Unfortunately i deleted the logs but i will check it next time. Thanks!

http://coinia.net/gapcoin/getbalance.php?top=100 fixed. It showed the balance in 2 times more.

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.

[GreekBitcoin]

btw it would help me a lot if you could compile a binary of gapminer and uploaded on github too

[coinfusion]

I got the miner to build on mingw64, but it crashes after submitting a share but before the share message is placed in the log. It looks like something with the line

    info_msg("Found Share: %0.10F  =>  %s\n",
             ((double) cur->get_pow().difficulty()) / TWO_POW48,
             (accepted ? "accepted" : "stale!"));

in shareprocessor.cpp causes the crash, since it stopped crashing (on testnet at least) once i turned it into just
info_msg("found share\n");

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?
