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

[minerja]

...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 ...

Regarding your last comment....
Unfortunately i think the vast majority of miners are now only in the game to turn a quick profit....
Perhaps, the project needs moving along to a different platform / audience, such as "folding@home", or the "boinc" crowds.
I have to say, for me personally much as i love mining rarer algos, overall if i am spending significantly more on power than i am earning (unless the coin is in its infancy) then i struggle to keep mining.
Thing is GAP is not a new coin, and hasn't really taken off (on this forum), so like i say, for it to grow, perhaps it simple needs pushing in other circles.
I hope so, cos whilst i have no issue leaving my wallet open, to act as a node, i can't continue to mine this coin, but also don't want to see it die....
Perhaps it needs aiming at a bunch of students, who might run with it ...

Nothing crazy, I've stopped to mine with the CRT miner for 6 months.
2 cpus and 1 gpu are back to Gapcoin, for now.

The Gapcoin Network / gapcoin.club nodes and infrastructure are in the process of being upgraded.

It is therefore recommended for Gapcoin node / wallets to add the following addnodes asap:

gapcoin.conf ...

addnode=jp.gapcoin.network:31469
addnode=gb.gapcoin.network:31469
addnode=sg.gapcoin.network:31469
addnode=nl.gapcoin.network:31469

In wallet ...

Help > Debug window > Console (Tab) and enter the following lines at the prompt:

addnode jp.gapcoin.network:31469 add

addnode gb.gapcoin.network:31469 add

addnode sg.gapcoin.network:31469 add

addnode nl.gapcoin.network:31469 add

...

Note: Additional addnode IP list can be found here: https://chainz.cryptoid.info/gap/#!network and clicking on [node list]

There are lots more gapcoin nodes running (and CPU mining in-wallet) than the block explorer currently shows!

...

If you don't have a Gapcoin wallet yet you can download the latest release here (and start CPU mining for gapcoins in your own wallet!):

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

- https://gapcoin-project.github.io/

...

For the extended GUI release on ubuntu / linux, open a new terminal window with Ctrl + Alt + T

wget https://github.com/gapcoin-project/gapcoin-core/releases/download/0.16.3.1.X/gapcoin-0.16.3-x86_64-linux-gnu.tar.gz

tar xvf gapcoin-0.16.3-x86_64-linux-gnu.tar.gz

cd gapcoin-0.16.3 && ./bin/gapcoin-qt

...

Cheers!

Thanks for your continued support BayAreaCoins!

Your exchange is seemingly running very well and you appear to be an honest broker.  

Just wish that you would de-list BCH and BSV though, as Bitcoin is and always was BTC.

I notice that someone kindly refilled your gapcoin faucet:

P.S. Riecoin RIC (another prime number based altcoin) should be worthy of a listing!

I like to give people a safe place to sell their free forks

We are however delisting Bitcoin SV because we can't even get it to sync...

I notice that someone kindly refilled your gapcoin faucet:

Very nice, thank you kindly whom ever did that!

The lack of interest for RIC and GAP sure is depressing... To think that while both projects reunited have maybe a hundred of miners, thousands many more are wasting resources in CPU/GPU hash coins just because they are popular, profitable, and had the luck to have someone with a lot of resources at their side to spread the word and build a true and supportive community. Our records would be so much more interesting if we had that many miners! Not counting the network effect that would put us in a virtuous circle and bring us developers and scientists to improve existing software and make the findings even more interesting and maybe expand the useful PoWs to more fields.
Really discouraging to see that all the interest we gather is from people like the dude currently spreading FUD on Riecoin and harassing me, or the other infamous #7 user.
And now some politics are wanting to ban PoW coins, of course they have no clue that PoW can produce valuable scientific data.

Minerja said some valid points... Our projects are already 8 years old so if there is no interest after all these years, why would there be suddenly some interest later. People are just discarding the projects thinking that they are dead or have no chance to get some traction anyway. Prices are remaining very low so we are in a vicious circle where miners are reluctant to stay for the reasons mentioned and we lose even more interest, and it becomes easy for some malicious people like the one I mentioned to destroy all our hard work.

Honestly as a Riecoin developer since several years, I don't have much hope anymore to see our projects get the attention they deserve while we are drowning under thousands of Shibs, Doges and silly NFTs and Defi that get all the attention. We might have more chances if we launched ourselves some joke coin on April 1.

By the way, while BitcoinFx and me are in good contact and support each other, Gapcoin and Riecoin developers still work pretty independently despite following very similar goals, so usually one coin would benefit from some development but not the other, and that work would have to be duplicated to benefit both coins, which is a real waste. Riecoin Core 22.03, based on Bitcoin Core 22.0, was recently released, but Gapcoin is still yet at 0.16.3 and not sure that SegWit is even activated... Let alone TapRoot/Schnorr Signatures.
Same for exchanges as they will often list one coin but not the other (or we have to pay the listing several times). And pools.
There are certainly things that could be done in this direction to make both projects stronger, reduce the work division, and have an opportunity to organize a "rebirth" of math coins that may be the key to gather some fresh interest.

Riecoin Core 22.03, based on Bitcoin Core 22.0, was recently released, but Gapcoin is still yet at 0.16.3 and not sure that SegWit is even activated... Let alone TapRoot/Schnorr Signatures.

No, segwit is not enabled for the Gapcoin chain, there's a handful of inveterate 0.9 holdouts - https://chainz.cryptoid.info/gap/#!network and we've been disinclined to force the issue (the Riecoin community seems rather more coherent). However, I take your point about the disproportionate negative impact of unnecessarily-duplicated effort. There is one unfortunate difference in the mining aspect, the "unreconstructed" GapMiner code still depends on the getwork RPC-API call and so that has to be re-implemented for each Gapcoin upgrade.

AIUI, 0.16 is the last Bitcoin version that enables versionbit "soft fork" upgrades, after 0.16 the segwit starting block height is hard-coded and (again AIUI) migrating to a more recent version would entail a hardfork - so that's why Gapcoin is frozen at 0.16. I did get an 0.20 version working but didn't take it to production. However, looking through the Riecoin release history it appears you folks successfully managed a hard fork from 16 to 20, which is encouraging.

I have some ideas that I'm working on with respect to mapping the blockchain into RDF (e.g. https://github.com/gapcoin-project/gapcoin-core/blob/6828bdebf2f07367799e41b04e081de24e322057/src/rpc/blockchain.cpp#L2186) and I'm doing some groundwork atm.

Cheers,

Graham

i try to mining, and i give this error  


Why?

[Hermes Mercury]

Hi, There any bootstrap for GAP?

[wizz13150]

Hi, There any bootstrap for GAP?

Hey, yes.
You can find it here, the first line :
Release & Bootstrap

And to quote M. Higgins :
'You just need to copy bootstrap.dat into your (empty apart from gapcoin.conf)  datadir folder, the client will detect it and import it - creates the blocks and chainstate files.'
 

This one is almost one year old now, but it's better than nothing (:

Here are some active peers for your gapcoin.conf file.

New Highest Gap found (not merit) for the Gapcoin network!
Gap of 28470 @shift 1024 (Merit 32.12)
The previous one was a gap of 28168 @shift 1024 (Merit 31.76)

Btw, the current hashrate is not bad :


 

[wizz13150]

Why?

Hey, hum, what graphic card is that ?
Is it the first run ? It's not even compiling or loading any kernel.bin  

EDIT: Okay, I can reproduce this error (but not the last line) using -d 1 instead of -d 0 (only one card on the computer)
You're probably just using the wrong device.
It can't load the buffer to nothing. I don't remember seeing the last line before, but -33 & -34 is about -d.
