...snip...

Somewhat obviously, while the Gapcoin network remains predominantly hosted on 0.9 clients, there is no point in me pursuing any upgrade of Gapcoin to 0.20/0.21.

Cheers

Graham


New club nodes running Gapcoin Core v0.16.3 will go 'live' before the end of next week.

Some existing nodes will be upgraded to v0.16.3 before 15th of July 2021.

This will be the lions share of the network nodes.

Cheers!

P.S. Continuing lack of community interest in this project is still shameful. Oh well ...

It's summer so ppl have other things in their minds but it's sad that they are not trying to use different shifts,

It's hot here now so I have reducet the speed off my computer. I'm still trying to make some new records.

They have a placeholder for us so maybe they will be a little easier on us when they see that there is activity here.
The community is overwhelmingly comprised of pseudonymous individuals but CMC won’t respond without an email address - I can't resolve that contradiction without giving them my email address, which I'm not prepared to do.

Gapcoin is listed on Coingecko so that's good. No need for coinnarketcap.

Need to fill in a rquest form.
Need to assess whether it's worth the effort.

Stumbling blocks in terms of assumptions of centralized organisation that are inappropriate to a decentralized cryptocurrency:

Quote
(SECTION B) Guidelines for 'Tracked Listings'

Note that these are just guidelines and meeting them does not guarantee a listing.

(1) Cryptoassets

For a cryptoasset to be considered for a tracked listing, it should meet the following guidelines:
    ...
    Must be traded publicly, and actively traded on at least one (1) exchange (with material volume) that has tracked listing status on CoinMarketCap.
    Provide a representative from the project with whom we can establish open lines of communication for any clarifications.

(SECTION C) Evaluation Framework

Beyond the guidelines, we perform our evaluation holistically and pay close attention to a multitude of factors (both quantitative and qualitative). Getting listed is therefore not simply a matter of ticking off a checklist or hitting predefined thresholds, as we benchmark submissions against others in the cohort. These factors include but are not limited to:

Community Interest & Engagement

A project’s usefulness is largely a function of adoption and its ability to foster meaningful interactions with its community and user base.

Team

The personnel, investors, and advisors are integral to the success of any given project, especially if there are transferable skills/experience/networks that can be leveraged. The conduct of the team (e.g. transparency and professionalism) will also factor into our assessment.


Circulating Supply is verified by our team through communication with the project’s team. We ask for details including but not limited to the initial distribution, private allocations, locked addresses, team-controlled addresses, and addresses containing portions of the supply allocated for future use.

We define Total Supply as the total amount of coins in existence right now, minus any coins that have been verifiably burned.


Cheers

Graham



It's not easy to deal with companies like Coinmarketcap. I did not like them much and when Binance bought them I have more things against them.

There is one more projekt that have taken GAP and maybe there will be a good one that overtakes the GAP.
They should not list other projekts with the same 3 letters. That maybe is easier for them to take care of. They have a placeholder for us so maybe they will be a little easier on us when they see that there is activity here. GTAP is not premined so that is a very good thing.
'It's a advertising platform to get more computers to this network and protect GAP as I see it.

I agree that they are not good.

record type:       


This Record is a good example of randomness in the blockchain!  (This Shift was lightly mined for a couple days only using 32 Core Threadripper, but the generated waves from surrounding shifts made it score a direct battleship hit) Generating Random using Backdoored Encryption is nearly impossible except to play the real world drama outside!

I propose a future Hard-Fork Gapcoin Blockchain using a Dash Coin Gapcoin Clone but using the X16 Algo all different Gapcoin Mining Shifts 16 different combinations using 16 RANDOM Rounds of encryption layers

You need to improve your Russian before you run it through Google translate. It's hard to understand.

A hardfork is just needed if something is broken or needed for future upgrades. There are not any benefits to clone broken code.

I read on mersenneforum that some off the members there dislikes crypto very much. It did not matter to them that they did not understand the concept. That means that we can't expect them to respect the boundaries of this coin. They are not happy over how ETH have made a shortage of graphic cards and they fear that a new token also will make a shortage of hard drives. So we could also exppect a targeting of this area.

THE good news is that it takes time to find all records in this area and their metod finds records faster but not all off them.

There have been a lack of upgrades of the miners and if we can make them better so we find more records maybe they don't find it so interesting to target this range anymore. There are still a lot of records to be found.

Boom !

My biggest, and the biggest Gapcoin's Gap.  Grin (length, not merit)

28168,C??,31.767181,Gapcoin,04-05-2021,386,1228769885602...

The previous one was a gap of 27666 @shift 896.

Agreed, well done Wizz.

That Craig Loizides is making things more difficult - https://www.mersenneforum.org/showpost.php?p=576044&postcount=239
Quote
Craig also improved the record for 15122, so there are now only two gaps under 25,000 with merit < 25.

For those that aren't neck-deep in it, a 386-digit prime means Wizz used a shift of 1024 to get that seriously-improved merit.

The existing-soon-to-be-previous holder of that record was Dana Jacobsen and the gap was between primes of 502 digits in length - which is why Wizz' merit is higher, it's the same gap size but it's larger in relation to the digit length of the surrounding primes.

INSERT INTO gaps VALUES(28168,0,'C','?','C','Jacobsen',2014,24.3700,502,'637*1201#/18390 - 23308');

One slight thing that nags at me is that we're always submitting 'P' (probable primes) and it would be nice to upgrade them to 'C' (confirmed primes). I have asked about this and I'll probably get a response in due course. I used Dana Jacobsen's eccp-dj to do the checking, as well as PRIMO (just to find out what prime certificates look like).

As for the Mersenne Forum's Prime Gap Search group, they seem to be heading into a different space entirely: “I've got two 3M+ gaps in the offing.” - those have to be some seriously large surrounding primes.

Cheers

Graham



Proving numbers are primes are not hard in this limited range. Proving that there is no primes in that gap is more work.

It would be good to have confirmed prime gaps.

Gapcoin has a very limited range to work with and other groups have improved their algos. The pow is limiting what range and how it's done., Frey did a good work to create this coin but it needs some improvements.

Mersenne group finds new nice gaps in a day and we do the same in a month. I changed to search in p88 for a record and so far I just have found one 25+ merit gap. To find a 30+ gap is hard.

Well done. Nice merit to that gap. Gaps gets bigger and bigger with higher shifts but to find a good gap with a nice merit needs a lot of efforts. There is most likely merits over 40 at that shift so you can improve it but that will take a lot of computer hours I think. I'm still testing some settings to improve my search for records. I'm also waiting for a good graphic card to improve speed.

This is for the build in miner.

"primespersec" : 2363506,
"testspersec" : 807895,

When I'm optimizing the settings I get 100000-150000 less primespersec but 30 000 - 35 000 more testspersec.


I don't know if I'm thinking it right but that's what I'm aiming for.

Yeah, I have seen that. That's why I'm aiming at the shifts that are not been targeted. I know the miner is a little optimized at thoose settings and you get a little less gap on the others. I hope I can get more inputs on that list. Thanks for your good work.

I don't like this. The problem with adding to much mining power without proper testing is that false primes can be accepted.Then network can run into problems. Instable.

Hey,

not sure what you mean by 'false primes'.

The only change in the fermat.cl is :
-  uint4 q[2] = {0, 0}; this is for amd
+ uint4 q[2] = {0, 0, 0, 0}; this nvidia

This is the exact same miner as before.
And how much is "too much" ? It seems to be kind of subjective.
As I tried to say, 1000M PPS would be 'only' a difficulty of ~24.5 .. Gapcoin was designed to reach 35 or 40.

I just doing this for puting my name on a finding and not for the coins. I know there is better ways to find the records.

And the Gapcoin community thanks you !  Smiley (at least me, ahah)


Can you please link to the miner you are using, cos the one i use, i get cpp:420 opencl errors

Hum, curious. Tested on linux, windows and for several cards.
We are talking about the rev4 or rev4.1 of the gpuminer.
https://gapcoin-project.github.io/downloads/
Not the oldest releases. It should works just by replacing the file.
Here is my miner, rezipped. (temporary)
What start line are you using ?

It was not an attack on you.

It don't work on my old laptop for some reasons. I have to check it out later. I can't update the blockchain on that one at the moment. Warning about some miners have problems.

Your record (shift 27) is :
6186,C??,31.594989,Gapcoin,28-04-2021,86,10733691..
The current record (shift 64) is :
6186,0,'C','?','P','Loizides',2021,27.9727,97,'20062693329181*211#/30-3044'

Congrats !
Any settings recommendations? or just default?

If you post an address (or PM me), I would be happy to send you something !

Don't forget to try the NVIDIA miner Smiley

I usually just tweak a little to gain a procent more. i don't know if the reported numbers are true or not. His record is with a lower merit. Maybe comparing with merits is better. Still I have far to reach the record.

Thanks for the offer but I don't need them. Thanks also for paying for the blockexplorer.

I don't have a graphic card to run it on. That old laptop will probably die fast if I would mine on it. I was just using it to make a working miner for the rest of you to use. No need now for that.

Okay.

How to say that.... ping @Everyone


HE DID IT !
The current GPUminer now works with NVIDIA cards. All you have to do is to replace the current fermat.cl file by the 'new' one.
This new file still seems to work with AMD cards.


We can properly thank benxy031 for his solution to make the current miner work, with the NVIDIA cards.


How To :
You just have to use this fermat.cl instead of the default one. That's all !! Shocked
This is not an Update. This is a Fix.

(in the gpuminer's "gpu" directory, no need to (re)compile)
(Temporary link, before integrating it properly into the project and releases.)


Obviously, that doesn't change the problem of a new miner or an evolution of the current miner.
But after so long without a working NVIDIA miner, it's still Awesome !


Enjoy, Plug in whatever you have  Cheesy, and don't forget benxy031 !


I'll run a GTX660 ?(not plugged yet?), GTX970 with 13 CUs (1.6M PPS), 750ti with 5 CUs (700K PPS).
I've tested a Quadro 410 512mb, it gives me 200K PPS for 1 CUs  Cheesy  That's the low limit.

Good Luck & Have Fun Smiley
2021 smells good.
