Its too bad this coin ends up like this when it offers so much more than 99% of the coins out there.

can you tell us how to do it?

What OS? Here is a guide: http://gapcoin.grn.cc/  Just skip the part about VPS... Generally speaking you download the qt, you run it and it downloads the blockchain, you download the latest miner, you start the miner pointing at the daemon...

Its too bad this coin ends up like this when it offers so much more than 99% of the coins out there.

Well it doesnt have the wow such coin much profit advertisement the other shitcoin have...


I had an idea lately. Let us select a random day in a month or so from now and call it "Gapcoin BreakTheRecordDay" (rename it however you like it). The idea will be that on that day we are calling miners from other coins too help us break the world record. Just a day trying... Then we spam(well some positive spamming, not too ugly) a bit the forums and social media and ask for help specific for that day. We could try to contact some crypto related news sites too. We gonna need someone to build a nice pool that can accept that traffic. Maybe we can talk with someone well known about this.  Someone should make a few images about that event. Finally we throw all the bounties that we have already gathered, plus we put a few more. I can add a few thousand gapcoins plus a few monero. The bounty will be given to whoever break the record. If a pool breaks the record i guess it can give according to shares of the spcific block. I believe we can gather a nice big bounty that can persuade people to mine gapcoin for a day. I dont know if we can succeed to break the record in a day. But a try wont be bad.

What are your thoughts? I am not sure about the technicalities. For example maybe we are going to fork the coin or whatever. But i dont think that anyone would like to destroy the coin...

Share your thoughts. If you find the idea okay lets start discussing for a few days. And then start organising it. Keep in mind that the whole thing shouldnt be utopically perfect. At least we can give it a try...

Folks who are transitioning to solo mining now that the pool is closed, don't forget to get the new Chinese remainder theorem miner (rev5).

If all the pool users transitioned to solo in the shift 500-600 range I'll bet we could find the overall merit world record fairly quickly.  Seems easier to find bigger merits in the higher ranges.

Are you noticed that gapcoin has been forked i guess? I mean blockchain.

Sorry guys, it's a false alarm of my wallet.

Can anyone who speaks Chinese reach out those most popular Chinese exchanges like btc38.com, bter.com, jubi.com?

@j0nn9 - Are you going to submit the next batch of new records?

There's a thread on mersenneforum where gapcoin is starting to get noticed by other gap hunters and number theorists.  There's a lot of cpu resources with folks who follow that forum, getting involvement from that community would benefit gapcoin.

Yes, I'll do it within the next few days.

Thanks for the hint!

CTR GapMiner Update

New Feature: Creating custom ctr files

The ctr algorithm is divided into 2 parts. The first part,
is a simple greedy algorithm which ties to find offsets
for each involved prime, so that the desired number range
has at least prime candidates as possible.

The second part is an evolutionary algorithm, which tries to improve the
results form the greedy algorithm. Therefor the greedy algorithm
will be executed several times with slightly different parameters, to produce
ctrs which differs in quality, which than can be used by the evolutionary algorithm.

The output is a text file which can be used by gapminer as an input for ctr sieving.

Parameter description:

Code:
--calc-ctr          Indicates that we want to calculate a ctr file.

--ctr-strength      This is used to variate the computing time spend
                    within the greedy algorithm. Higher strength
                    can yield better results.

--ctr-primes        The number of primes to use in the ctr file. The more
                    primes the better the ctr result, but the shift
                    also increases. Minimum shift can be calculated as
                    the binary logarithm of the product of all primes:
                    log2(p1 * p2 * ... *pn).

--ctr-evolution     Whether to use the evolutionary algorithm or not.

--ctr-fixed         This number indicates the number of starting primes
                    which wound get touched by the evolutionary algorithm
                    the offsets for the primes 2,3,5,7,11... are mostly
                    perfect computed by the greedy algorithm, and changing
                    them only declines the result.

--ctr-ivs           The number of individuals used in the evolutionary algorithm.
                    More increases computing time but mostly also the
                    result quality.

--ctr-range         Percent deviation from the number of primes.
                    Useful if you don't want to look for a specific number
                    of primes.

--ctr-bits          The shift value you later use for sieving has to be greater
                    than log2(p1*p2*..*pn). With this flag you can fine tune a specific
                    shift by setting this to shift - log2(p1*p2*..*pn).

--ctr-merit         The target merit (while testing the ctr it seamed that
                    sieving for target-merit - 1 yields the best results)

--ctr-file          The target ctr output file. You can open this with a
                    text editor. Look for the n_candidates value, the smaller
                    it is the better the ctr file.

Trying the new miner and generating a new crt file.  Can you post an example command to mine after the ctr file is generated?  Do we still use --sieve-primes?  Is ctr-evolution used in the ctr generation and the mining command?

ctr-evolution and ctr-primes are only necessary for generating the ctr file.  --sieve-primes will still be used for mining.


Mining still works the same way as in the previous ctr-miner version:

Code:
./gapminer-cpu localhost -p 31397 -u <rpc-user> -x <rpc-password> --shift 1024 --crt my-ctr-file.txt --threads 4 --fermat-threads 1

nscythe, same one that has all the cpu power?  If you're still mining on shift 25 you may mine faster on the higher shifts (400-600).

It's still solo mining but the second release of the chinese remainder theorem, this latest release let's you build custom crt files.
