Request: If you have some free CPU power then try mining Gapcoin

[BitcoinFX]

As the thread title requests - If you have some free CPU power then try mining Gapcoin !

Gapcoin is a prime number based p2p cryptocurrency and the largest, decentralized prime gap search.

The original developer has sadly passed away, however the project is ongoing at: https://gapcoin.club

With increased hashing power (and continued development) the Gapcoin network will discover new Prime Gaps.

See: https://gapcoin.club/primegaps.php

Lets try to get cryptocurrency back in the news for all the right reasons again. Do it for the math and not just for the money.  

Gapcoin thread here at bitcointalk.org - see: https://bitcointalk.org/index.php?topic=822498

Thank you.

Or try Riecoin holder of world record  

Indeed. Riecoin (and ofc Primecoin) have already achieved some new records relating to Prime Numbers.

Gapcoin is specifically searching for Prime Gaps - see: https://wikipedia.org/wiki/Prime_gap - which is quite different to both Riecoin and Primecoin.

"But how are prime gaps useful?

Prime numbers are interesting for lots of mathematicians around the globe, and they're also important to every day cryptography (see RSA ).

Researches about prime gaps could not only lead to new breakthroughs in the bounded gap, it may also help proving the Twin Prime Conjecture and maybe even the millennium problem, the Riemann hypothesis. Who knows?"

 

[BitcoinFX]

Many alt. coins have come and gone, but Gapcoin remains resilient and is perhaps moving towards a resurgence.

Although, the developer is awol development is continuing. Thus, the request remains ...

If you have some free CPU power then try mining Gapcoin!

NEW PRIME GAP OF MAXIMUM KNOWN MERIT
- http://gapcoin.club/new-prime-gap-of-maximum-known-merit-press-release.php

The Gapcoin network (Jonnie Frey, developer), a Bitcoin derivative which employs a hashing algorithm to search for prime gaps of high merit, has discovered a new prime gap of maximum known merit, a gap of G=8350 following the 87-digit prime P1=293703234068022590158723766104419463425709075574811762098588798217895728858676728143227. The merit M=G/ln(P1) of this gap is M=41.93878373153988, the largest merit of any known prime gap, and the first prime gap to be discovered with a merit exceeding 40. The endpoints of the gap have been certified as primes deterministically, using the Akiyama-Kida-O'Hara UBASIC implementation (1988-1992) of the APRCL2 test, due to Adleman, Pomerance, Rumely, Cohen, H. W. Lenstra, and A. K. Lenstra (1984-1987).

GPU solo mining is also available, but here be dragons! So, test with older cards / rigs first or until new miners are released.

Pool operators and software developers welcome!

IMHO the gapcoin project deserves a higher market cap than say Litecoin.

Both Bitcoin's and Litecoin's PoW are totally 'useless', although we may not fully understand currently if it might have some use later on for finding 'patterns' or discovering 'weak keys' etc.,

Gapcoins PoW is useful now.

Herewith, New Pool and (basic) Mining guide (however, the relative difficulty is still low enough to mine in the wallet with your CPU, just like original BTC) ...

...snip...

CPU Pool mining set-up guide:

Pool: https://gap.suprnova.cc

Linux:

The optimal 'working' binary release for CPU mining in the pool is currently gapminer-rev4. I've tested this release on Ubuntu 18.04 LTS and the dependencies are met and it's very stable.

- https://github.com/gapcoin-project/GapMiner/releases

At present, I will suggest set-up as follows:

Code:

wget github.com/gapcoin/GapMiner/releases/download/gapminer-rev4/linux.zip

Code:

sudo apt-get install p7zip-full

Code:

7z x linux.zip

Running gapminer-cpu (requires pool registration and worker set-up):

Code:

linux/64/cpu/gapminer-cpu -o gap.suprnova.cc -p 2433 -u YOURusername.YOURworker -x YOURpassword --retries -1 -t 1 --stratum

N.B. Where -t is the number of CPU cores (threads) to mine with.

DONE !

IMPORTANT : Please read how to action a CPU limit of upto 75% max. before you start Mining on a cloud server! (also useful for desktop mining upto say 97-99% max. to help preserve your hardware and/or productivity!) ...

- https://bitcointalk.org/index.php?topic=822498.msg40934201#msg40934201

N.B. No requirement to run gapcoind for pool mining here of course ... however the PID your looking for instead in top is: gapminer-cpu

...

Windows Desktop:

See: https://github.com/gapcoin/GapMiner/releases/

Download: https://github.com/gapcoin/GapMiner/releases/download/gapminer-rev4/windows.zip

"GapMiner revision 4: supports CPU / GPU mining.
Changes: rewrote stratum network stuff to remove boost dependencies and to fix windows support."

Currently untested. If someone would like to confim that cpu mining on windows is still working in the pool with gapminer-rev4 that would be great!

TBH I see absolutely no reason why it wouldn't ...

Simply unpack the windows.zip , then navigate to locate gapminer-cpu.exe , move it to an appropriate folder on your drive, second mouse button click > Send to (create shortcut) to create a shortcut on your desktop (or drop and drag). Now second mouse button click the shortcut link > Properties and append to the Target: line ...

Code:

 -o gap.suprnova.cc -p 2433 -u YOURusername.YOURworker -x YOURpassword --retries -1 -t 1 --stratum

Apply and run gapminer-cpu.exe via the Shortcut.

N.B. Again, where -t is the number of CPU cores (threads) to mine with.

DONE !

N.B. or alternatively the .bat method should work just fine!

Good luck!

Gapcoin now has a community-led Github repository of its own: https://github.com/gapcoin-project which is now host to all the associated Gapcoin repos (i.e. Gapcoin, Gapminer and the submodules Gapcoin-PoWCore, Evolution and C-Utils). I strongly recommend that you sign up for a (free) Github account, at least so you can be automatically informed by email of changes to the Gapcoin project resources even if you don't wish to contribute to the project directly (e.g. by helping to maintain the project web site, see below).

On behalf of the project, I have taken advantage of Github's free static website maintenance and hosting facility (GitHub Pages) to create a community-led web site for the project - https://gapcoin-project.github.io/. The reason it's "community-led" is that the source code for the web site is maintained in a dedicated Github repository - https://github.com/gapcoin-project/gapcoin-project.github.io and can be maintained/extended/edited by any member of the project that wishes to do so. The advantage of a community-led and community-maintained approach is that the resources are no longer the responsibility of just one person but the onus is shared across the group.

In order to get things moving, I've used the Opentheme Jekyll site template (the same one I used for the mersenne forum's prime gap search group) to provide structure and functionality, it's now a matter of re-branding and adapting the example content provided. This approach has the advantage that the site can be hosted locally, edited/changed as convenient. The final changes can be committed and pushed back to the Github repos and they will then be automatically published to the project web site. It's a popular approach and all aspects are well-documented (search for "Github pages" and also "Jekyll").

I have upgraded the Gapcoin codebase to Core 0.9.4 (see the branch v0.9.4-gap) (use git clone -b v0.9.4-gap https://github.com/gapcoin-project/gapcoin.git) and have added some functionality.

The client now has a built-in "block explorer" (aka a GUI presentation of data otherwise accessible via the JSON-RPC API or console)

Block display:



Transaction display:



The client now offers a dialog box showing a list of Gapcoin-held prime gap records along with the information recorded in the block data - with the aim of casting a little more illumination on mining settings:



I have edited the contents of the "About Gapcoin Core" dialog box to have two tabs, one showing the standard copyright credits (and some other stuff) and a second tab commemorating/crediting John Frey:



I've added a "Mining" tab with fields for setting values for shift, sieve size and number of primes in the sieve:



and a "Notary" tab, easing Gapcoin's (inherited-from-Bitcoin) utility to act as a blockchain-preserved notary.



I've also committed a "dumpbootstrap" command to the JSON RPC API command set - it dumps a file of linearized blocks (bootstrap.dat) which can be read back in (takes a couple of days, even on my fast-ish laptop).

I have updated the pnSeeds entries (the IP addresses first consulted by a syncing-from-zero client) so no need to hand around lists of addnode IPs, there's also a fresh working testnet and a testnet pnSeed, so clients started with -testnet should sync up very quickly.

I have added a download-and-build script for BerkeleyDB 4.8 for convenience when compiling a Gapcoin client with full wallet portability.

With respect to integrating GapCoin-PoWCore into the code, it is also a submodule for GapMiner, so rather than have to maintain two copies of the same code, I simply updated the submodule references for both Gapcoin and GapMiner.

Gapcoin is a prime number based p2p cryptocurrency and the largest, decentralized prime gap search.

How come nobody give two shits about that? How do you think is what you say reflected in its valuation? Literally no one gives a salamander about what gapcoin is because the space is on the brink of decay and the more weeks pass the higher the chance that even leading crypto echelons like ETH will never recover. Its over. Stop paying attention to crypto trends and shelve back to your normal crud routine.

Hah! You are this guy:

I think I would hook an asic to it. With it, I will put bitcoinfx punk on his knees. He swanks being a solo guy, well good for him. Maybe your a soloist in every other aspect of your life, namely self-stimulation of ur genitals and fulfillment of other needs, but Im not that guy. I know that no one dared to put an asic on it heretofore. I will be the first humming internet guy to end this coins life cycle.

Makes total sense because very few people take poetic liberties when formulating a response in the bowels of the Altcoin ANN section. I would reward your peculiar wordsmithing with a merit but as I consider BitcoinFX a friend (in the loose, internet-driven sense of the term) that would be impolite, albeit not as much as your response.

Instead, be happy that your accomplishments have been memorialized in one of the greatest tribute threads to ever caress the forum and let that serve as motivation to continue with your cryptic buggery.


Sorry BitcoinFX for hijacking your thread for a moment. I will use my bump power to bump it to the top of the ANN section to make up for my intrusion.

Gapcoin should be listed (re-listed) on additional markets in the future.

At one time this genuine altcoin was listed on coinmarketcap and traded with relatively high volumes on Cryptopia, Poloniex and other exchanges.

Gapcoin was de-listed mainly due to a lack of continuing development and perhaps some uncertainty and clarity in regards to the project being stalled and/or future proof etc.,

Useful proof of work (finding prime gaps) helps to ensure that Gapcoin has a practical purpose and a longevity above its market (monetary) functions.

[Balladtony77]

Since 2015 this gapcoin is only listed on two very low exchanges that probably 80% of crypto users haven't heard about before, this is not so good, it shows nothing but lack of good development so far, it's been way too long already

"If it ain't broke, don't fix it" ?

The gapcoin blockchain holds and discovers new Prime Gaps through useful proof-of-work, it works!

No such thing as an economic point of no return here ... just hard math and a sound Bitcoin based crypto-currency project.

Unlike fake tokens, BS ICO's and pump 'n' dump schemes we have not paid for exchange listings.

Gapcoin is testament to the ridiculousness nature of the entire crypto industry and a world ignorant to its true potential.
