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

[BitcoinFX]

Is there a blockchain download for this anywhere?  I mined this when it first came out.  Saved the wallet but rebuilt the machine.  I have to sync from scratch. 

- https://gapcoin.club/linux-gapcoind-setup.php

- http://138.197.159.202/downloads/Gapcoin_blockchain.zip

This .zip will work OK in windows. However, you have reminded me that the current blockchain download link could use an upgrade. This chain is around 24hrs worth of syncing behind the current block count, depending on your network speed ofc.

New seed nodes and an updated blockchain download link ... soon.

OK. Back to basics then, anyone?

"... What is Gapcoin’s value backed by?

Gapcoin is valued for the things it can be exchanged to, just like all the traditional paper currencies are.

When the first user publicly announces that he will make a pizza for anyone who gives him enough Gapcoins, then he can use Gapcoins as payment to some extent - as much as people want pizza and trust his announcement. A pizza-eating hairdresser who trusts him as a friend might then announce that she starts accepting Gapcoins as payment for fancy haircuts, and the value of the Gapcoin would be higher - now it would be backed by pizzas "and" haircuts. When Gapcoins have become accepted widely enough, he could retire from his pizza business and still be able to use his Gapcoin-savings.

Currently, Gapcoin is in beta development stage, and some new features need to be implemented before the system is well suited for real use. The system already works on the basic level, though, and you can trade with it if you want to. ..."

As a Tor exit node operator (and contributor to tornull.org) I spend several hours a week responding to incidents of 'hate speech' being unfortunately perpetrated (by 'unknown' individuals) and whilst free speech is one thing these comments are most certainly deplorable.

I'll offer my hillbilly philosophical view on that.

Fiat has, as one of its main purposes, the managing of scarcity, trying to channel resources in a way that herds desperate people scratching for more resources.

Bitcoin has some improvements over fiat but does not actually produce anything, so even if its users are more progressive it still falls back to the fiat goal of managing scarcity.

Gapcoin and the other math and science coins though do actually produce a commodity through their use.

So even if it isn't apparent yet, coins like gapcoin will eventually be backed by the value of what they produce.

All that is left is for people to accurately value what coins produce, and then evaluate how what gapcoin, for example, produces compares to what a pizzeria or other group produces.

Indeed. Gapcoin's value is undoubtedly, backed by Math ...  

We can assert that all prime gap records attained by Gapcoin do add to the value of the entire blockchain.

However, this perceived relationship between proof-of-work and value is somewhat unquantifiable in reality.

In terms of Gapcoin, if we consider 'the block' which currently holds the record for the prime gap of maximum known merit - do said coins at this address hold a value above other coins on the chain? In reality, probably not. Things are only worth what someone is willing to exchange them for at any given time. Moreover, auctioning the private key / wallet for the address also carries 'risk' for the buyer, detracting from value or worth.

If we consider transfer of said coins, in this regard, then the only real claim of additional value is perhaps linked to the origin of the coins. It has been asserted already that Bitcoin's of a known questionable origin (or tainted coins) may carry an (actual or perceived) reduced value over coins produced by new blocks or those with a determined 'clean' origin. This concept was developed in Zcash where "All coins are created equal.", due to the ability to hide the origin of coins via shielded addresses.

TBH most folks considering or using Gapcoin as a currency probably won't really care a jot in this regard, in exactly the same way that most users don't know or don't care about the cryptography which underlies Bitcoin.

You are 100% correct though. Gapcoin has two products! Gapcoin's and Prime Gap records ...

Hi there,

first of all I’d like to thank you all for your great support over the years.
Second I want to confirm that Gapcoin indeed broke the World Record for the largest known prime gap of maximum merit:

NEW PRIME GAP OF MAXIMUM KNOWN MERIT
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).

World Record listed at: http://www.trnicely.net/#MaxMerit

@j0nn9 - An open question from the Gapcoin community ...

Do you now have plans to continue with Gapcoin's development and/or with the future release of updated software, now or in the future ?

Kindest Regards,

[BitcoinFX]

I wish you advance!
Plausible project, very nice results, excellence idea.

Welcome one! welcome all !?!

Let's recap ...

- Gapcoin launched in 2014 ...
- Fair launch. No Pre-mine. Based on Bitcoin Core code base.
- Not a token. Not an ICO. No pre-sale.
- Currently still operates on a fully decentralized basis and unlike Bitcoin you can still mine Gapcoin with a fairly standard PC using your CPU and the wallet (just like you could with Bitcoin in 2009-2010 before pooled mining was invented). Gapcoin had a pool at one time, but it closed down.
- Difficulty adjusts every block and increases logarithmically. Which means slightly more coins are produced, when more people are mining!
- Every new block (with increased mining difficulty) has the potential to be a new world record prime gap.
- As of December 2017, the largest known merit value (prime gap) and first with merit over 40, was discovered by the Gapcoin network. (quick - someone call Norris McWhirter).

Now that the Gapcoin network infrastructure is more stable, I'm going to start website promotion for gapcoin.club , across multiple traffic exchange platforms. This will hopefully grow interest in the project organically. Various traffic exchanges also accept web banners 468x60 , so in regards to your response above I've been working on a simple tag line which tries to be more new user friendly than  "...

Does anyone know who is actively updating the records list?  http://gapcoin.org/primegaps-length.php

It appears to be getting updated maybe once a month.  I've been targeting records in the larger shift ranges, 400-600 and sometimes close to 1024.  Would be nice to see it get updated more often.

If anyone wants to go after the 1020-1024 range here is my best customized sieve file.  Strange thing is gapcoin seems to not record about 15-20% of found blocks for these much higher shifts for some reason, not sure if it's a bug or something else.  Anyways if you're more interested in setting a bunch of new records than getting more coins and have the cpus available then this should do you well.

Thanks pdazzl. I will certainly give it a go.

I also notice a drop in the number of blocks found using the CRT miner, probably around that percentage. One wonders if anything in the standalone rpc miner is a miss? Anyhow, I'm still finding the 896 shift to be optimal for my set-up.

It must be j0nn9 who is again updating the records list at gapcoin.org - I don't have access there.

Good good!

[pdazzl]

@BitcoinFX

Here's some of my optimal 400-500 shift sieves.  Check the pps on these guys don't think you'll be disappointed  

I spent some time sieve searching/optimizing, think these are near the top end of CRT's throughput capability.  The 512 sieve I've set a couple of records with already, got some ~28-30 merits.

Nice one!

Something which I think is really essential for any new CPU mining software builds (and the wallet) would be the ability to set a % of CPU mining. My current work-around for this is to use cpulimit;

Code:

sudo apt-get install cpulimit screen

Run gapcoind;

Code:

cd gapcoin/src && ./gapcoind

Code:

cd

You then need to start a screen instance for top and run top;

Code:

screen -S top

Code:

top

This will display all of your systems process ID's - PID's.

You then need to find the process ID for gapcoind. It's most probably near the top of the list.

Then hold and press crtl + A + D to exit the screen session.

Note that if you want to re-enter the same screen session later to check % CPU mining is working then you need to do;

Code:

screen -r top

NOT

Code:

screen -S top

as this will just start another new screen session! You only need to do this after you have re-started your server!

Back at the prompt execute;

Code:

cpulimit -p PID -l 64 /dev/zero &

Where PID is your gapcoind numbered process ID and 64 (example) is the maximum CPU usage for gapcoind.

Note : I wouldn't recommend going much below 64% CPU usage or much above 74% CPU usage per single core instance - depending on what else your server is running.

Hit enter twice, first to confirm the process ID and second to action the CPU limit into effect.

Now we can start mining with gapcoind;

Code:

cd gapcoin/src && ./gapcoind setgenerate true 1

Code:

./gapcoind getprimespersec

Code:

./gapcoind getmininginfo

etc.,

Code:

cd

You can now confirm that the mining process (gapcoind) is using the set CPU limit by checking top again.

Code:

screen -r top

Then hold and press crtl + A + D to exit the screen session.

To exit the SSH connection with the server it's;

Code:

exit

and enter.

I will link to this post from https://gapcoin.club/linux-gapcoind-setup.php and also add more 'free' cloud server company options for mining in this regard.

Note that the server company may still open a ticket for 'high CPU usage / abuse' - you might explain to them that you are running a node for a mathematics / scientific research project and tell them you can further restrict the CPU usage, if necessary.

The flag for constant CPU usage varies. However, if your total system use remains on average below 85% to 90% then you will probably go undetected as a 'good egg' in this regard.

Good luck!

One coin which I know of which had this feature built-in to the miner is coin Magi (XMG).

Unfortunately, that codebase is authored in Javascript and would likely prove a challenging integration (I confess I've spared myself the chore of actually checking). OTOH, Dropcoin (https://bitbucket.org/nscrypto/dropcoin.git), (using a Core 0.10 base vs Gapcoin's Core 0.9 base, i.e. close but still non-trivial) has a "percentage of available hashpower" slider in a GUI "mining" tab which might suffice but the feature is incomplete because there is no corresponding parameter for the RPC-API setgenerate call. Rectifying this might be feasible/practicable.
