Topic: [ANN][GAP] Gapcoin - Prime Gap Search - New Math Algo - CPU / GPU - Zero Premine - page 16. (Read 287669 times)

At the moment, I do seem to be the only one interested in curating the codebase for this altcoin but it's open source and so that could change at any point.

In the context of a cryptocurrency, that holds true for compiled binaries from any source. Bitcoin has evolved a "gitian build" process which produces binaries with reproducible hashes that can be cross-checked against a recognised value (see this write-up for a narrative description of the approach). That'd be the best bet for commissioning the creation of a compiled binary.

(Oh, and the contemporary Bitcoin repos has a suggestively-titled directory build_msvc directory ... https://github.com/bitcoin/bitcoin/tree/master/build_msvc but I suspect that's not of immediate use on a vintage 0.9.x codebase).

Open source

gjhiggins Thanks for the detailed answer!
As I understand it, you are the only person who has continued to develop the gapcoin.
I could find a person who could compile the gui-wallet 0.9.4 for Windows, but there is a question of trust, you need a trusted person so that there are no unpleasant surprises.

On behalf of the members of this group, welcome.

Since the advent of VMs and Windows Subsystem for Linux, they certainly do but most Windows users seem to have become habituated to the convenience of leaving it to someone else to provide cross-compiled binaries.

The existing Windows binaries were (probably) cross-compiled from (what is now) the legacy codebase (0.9.2 - https://github.com/gapcoin/gapcoin/releases) back in 2015 when the code was contemporary with OSes of the time. Unfortunately, despite considerable effort, I haven't been able to successfully cross-compile a Windows binary from the "updated" 0.9.4 version - note that the term is slightly misleading, it's hardly updated, just adjusted to cater for backwards-incompatible changes in the newer boost libraries that are compatible with contemporary Linux versions - just in order to get it to compile. The 0.9.4 additions are merely cosmetic, the underlying engine remains unchanged. Back in 2015, the "build-msw" documentation (https://github.com/gapcoin/gapcoin/blob/v0.9.2-gap/doc/build-msw.md) only dealt with building the headless daemon (i.e. the non-GUI version) and so altcoin devs were left to their own devices as regards Windows GUI binaries.

I tried back-porting the "depends" cross-compilation solution that was introduced in a later version of Bitcoin (0.10, I think it was)  but the solution is tailored to specific versions of the support packages and in particular the specific Qt packages referenced are simply no longer available so I was obliged to work with contemporary versions of the packages as available in Bitcoin Core 0.18.

The above-refefenced work has been done in a separate branch (https://github.com/gapcoin-project/gapcoin/tree/v0.9.4-gap-mingw/depends) It sort of works - the headless daemon builds but I haven't been able to successfully use it to cross-compile the Windows GUI version. In principle, the depends solution is relatively easy to use, in the depends directory, type make HOST=x86_64-w64-mingw32 -j4 to create the cross-compiled packages and then, in the top-level folder ./configure --prefix=`pwd`/depends/x86_64-w64-mingw32 will cross-compile the coin and link against the cross-compiled packages. Qt is persistently cranky, though.

As an alternative approach, Windows users could d/l the QtCreator package and try use that as a platform for compiling natively on Windows (after first compiling the boost, gmp, mpfr, ssl, miniupnpc, qrencode, zlib, zmq, etc dependencies) but aiui, it's something of a nightmarish process.

As regards regards the platform preferences of the group, I'll leave you to draw your own inferences from the fact that the chainz explorer reports:

Client Version	number	percent	total
Satoshi:0.9.2	16	84.2 %	84.2 %
Satinki:0.16.3	1	5.3 %	89.5 %
Satoshi Gapcoin Clan:0.9.3	1	5.3 %	94.7 %
Satoshi:0.9.4	1	5.3 %	100.0 %

(The 0.16.3 version is mine and is undergoing trials).

Cheers

Methinks this coin features a very high percentage of Linux folks.

I was interested in this project, I read this thread and admire the people who support this non-commercial coin.
I would also like to make my own contribution.
I have a question - I downloaded a wallet for Windows, version 0.9.2.0-unk-beta
I read the thread found a description branch v0.9.4-gap
I loved this advanced wallet. but there is no compiled version.
Why is that?
Not everyone has the ability to independently compile for Windows.

@PrimeObsession - perhaps you can shed some more light on this?

I agree it is most certainly an anomaly. However, even the original PoWCore seems to point to John Allen Frey being involved here ...


...

We are of course assuming that some unknown others took the project reigns for sometime ...

perhaps Dr Thomas Nicely or someone else close to Frey ... ?

See: https://bitcointalksearch.org/topic/m.53120640

It remains a mystery as to who, briefly, updated the gapcoin.org records, who is continually paying for the domain name and hosting (if it isn't long-term paid for on auto renewal!?) and exactly which genius(es) actually contributed and conceived building and launching Gapcoin / PoWCore.

Several requests have been made in this thread and elsewhere for the original developers (or anyone associated with them) to come forward, yet to-date, no one has come forward and/or contested my/our (community) assertions.

Kind Regards,

Thanks (again) Graham ^


@miner_brown

If your using MS Windows you might try following this guide to sync. the Gapcoin blockchain and then start mining GAP ...

- https://gapcoin.club/windows-gui-setup.php

...

TBH Gapcoin has been in a state of flux for a good number of years now and we hope to combine community efforts more fully in the near future to give this project the recognition it deserves.

An upgraded wallet for Windows will be part of that. However, the existing release remains functional for now.

Cheers!

Welcome to the group.

Yes it is still possible to mine (see the chainz block explorer on https://chainz.cryptoid.info/gap/).

From your description of the client's behaviour it sounds like it's not finding any currently-connected nodes on the network, i.e. it's failing to sync. This can happen with elderly binaries in which the original hard-coded initial connection nodes (called "syncnodes") have long since gone away. In order to enable your client to sync to the network, you need to add the following list of node IP addresses to the Gapcoin config file, any of which should enable the client to start syncing:


Alternatively, if you are uncertain about how to change the config file, you can use the "Debug Window" menu selection to bring up a dialog box, select the "Console" tab to get a console in which to  enter the command: addnode 37.139.15.251 add followed by addnode 37.139.15.251 onetry. If your client doesn't report that it is connecting to the network, try another IP address from the list (if necessary, repeat until successful. If ultimately unsuccessful, report back here).

All the above nodes are Gapcoin nodes configured to accept incoming sync connections (the chainz list of connections includes nodes which aren't serving/listening and while those nodes do support the network, new clients can only sync from nodes configured with listen=1, described in the command-line help as "Accept connections from outside"). The reason there are so few clients that accept incoming connections is that for most home setups behind a router, enabling connections from the outside will only actually work if the router connects the client internally via UPNP).

Finally, if you prefer not to wait the several hours that it will take the client to sync, you can download a zipped current snapshot of the indexed Gapcoin blockchain (4.2Gb in size) which I have made available, to be unzipped in the Gapcoin data directory. When starting the client, it should then take just a few moments to sync up completely.


Cheers,
Graham

I am new to the forum and came to this project, could you give me more information about whether it is still possible to mine or the project is already dead. I downloaded the wallet waiting for advanced / mining to come and it tells me that the last block was created 6 years ago I do not understand why the web has remained from 2014 to 2020. Some summary information about what is happening with the project.

Indeed. Big changes are afoot!

Happy bday gap!

Gapcoin Launched Tue Oct. 21 2014 - 18:00:00 UTC

Happy Birthday Gapcoin, it's really been six years! Glad someone remembered.

Perhaps it's also time for a new roadmap!

Happy 6th Birthday, Gapcoin!

Thank you Jonny, and all the Gapcoin's contributers, supporters, enthusiasts and sympathizers.

New records await us ahead!

Asked the following in C-Patex (exchange) thread topic ...

as well as emailing support @ c-patex . com from the Gapcoin Club email address.

... something something covid-!? *shrugs*

...

2nd block explorer well underway, so we just need an active 3rd exchange and then it will be almost time for a new forum announcement and a fancy new website !? A 2nd or 3rd pool !?

Anymore for anymore ? Gapcoin's not going anywhere folks, so time to wake up !

That thing is a 32-bit single core ARM Cortex-A9 666MHz SOC. It isn't an FPGA. It runs some kind of Linux kernel most likely and can be programmed just like any ARM chip. A Gapcoin miner can be integrated probably, but it will serve no practical purpose performance wise.

Out of curiosity do you think GAP should look to FPGA tech?

I have a idea that could be very interesting for those who mine bitcoin with ASIC's the controller boards seem to have embedded a Xilinx. XC7Z007S-1CLG225C ZYNQ chip (CLG225ABX1801) <-- Data sheet ref.

https://www.digikey.my/product-detail/en/xilinx-inc/XC7Z007S-1CLG225C/122-2002-ND/6593125

What is there was a way to flash the controller boards with a Bitstream and have them work on GAP coin as a dual miner the ASIC part still mining bitcoin and the FPGA on the controller board used to connect to the gap network?



Surly if 10000's of these boards were flashed and run as a kind of merged miner in the sense then the gap network would really start to grow.

Just a thought but would be pretty epic if possible.

Willing to donate boards for development if people were interested.

Please excuse the dust in the photo!

Money and "Internet" fame are what makes everyone drunk and to kill their own friends while drunk.


Excluding participants due to different perceptions of reality is wrong. 


I can guarantee everyone involved here.  Sinbad Gutherie is not stupid nor is he trolling. 


To ignore the absolute treacherous path that Alt-Coin markets have displayed everyone running for the money drunk with fame for the moment hoping to dump their bags to Goldman Sachs and company ect......


I know most don't nor could understand the intricate nature of financial chicanery, but their is an extensive history of it beyond the internet age, but which has invaded internet land with full force. 


I know this, there is no successful Bitcoin Code Clone that has ever been successful, and that is a FACT!


Even Namecoin which has everything on a golden platter, merge mining with Bitcoin, NO ONE CARES!  FACT!


Everyone wants the CIA approved Drug Coin a.k.a. Bitcoin.  Because Goldman Sachs and the Printing Press dictates the winners and losers.

It is a double edged sword.  Bitcoin has generated some good things and bad.  But it's foundation the so called Satoshi Vision was Good.  But his vision was quickly hijacked.  Bitcoin without Silk Road or Wikileaks is basically nothing. Bitcoin has had so many VAST thefts let alone the lack of understanding of most how to back up wallets ect....

It's fine, I don't care about dying without servants in the cold?  Why worry about worthless things?  Death will come eventually? 

Do you imagine fighting over simple things will bring about wealth? 

Wealth for the most part has ever come about by the Victorious Army.  With each Victorious Army, dictating the new terms.  Each until their fall.

Sheesh Mate, this was a good forum till you turned up....looks like most people don't want to know your opinions, and no-one seems to want your websites, so why not either do all this yourself, or leave it as it was....
Thing is, if i was a newbie to this forum, and saw all your "speeches" i'd simply click "next"...if you honestly think having a go at everyone when this coin is trying to compete with over 2500 other coins, well, enuff said.
Might be best for you to just take the open source code and develop your own "math" coin, cos clearly this one isnt't for you...oh and before you accuse me of being a "bag holder" i don't even think i have 1000 coins, i just throw a few threads at it now and again

WTF with you ? Please respect your words and Shut Up definitely, troll.
It's Not a question.

Thanks, Wizz.
