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.

j0nn9,

can you 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 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.

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

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 Huh

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 Cheesy

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...

Thanks!!

300 min / 60= 5 hours

Is it possible to make gapminer mining on port 80? I tried starting daemon with port 80 but it says that it finds no headers no data.

The wallet can create a new address for each new generated block.

Anybody working on a windows based RPC miner? I'd like to hijack some of the other machines in my office without setting up the wallet on each of them.
