Topic: [ANN][GAP] Gapcoin - Prime Gap Search - New Math Algo - CPU / GPU - Zero Premine - page 16. (Read 287931 times)

Yoh, i can't answer in a technical way.
But as I know, CRT will be used to mine higher Shifts and for 'huge' cpu/gpu power (~1,5M+ pps).
I don't use CRT miner... I'm waiting for a gpu developer to fall from the sky to try higher ranges.

Did you add known nodes ?!
--extra-verbose doesn't give you additionnal infos on the init failure ?

Wallet launch (~1 minutes) is op for me.
Usually with a 500k pps cpu, i'll find several blocks a day. Eventually 1-5blocks/3hours.
________________
Starting pool miner ~500K pps cpu :

Found share at 22.4628 merit is a valid block after a few minutes.

________________
If you're here to mine at high shift range and for high merit gaps you'll need a lot of cpu power.
And if you're here just to mine without 'mathematical goal' or low cpu power, go for standard miner at a standard shift range (25-32) and connect to the pool

I leave the technical approach for others ! Sry
And someone to invite you on Discord.
They will probably need to know you miner's launch command, with options. If you mine at shift 1024 [...] with 200K pps, good luck.
Miners probably need a lot more optimizations (mathematicals/gpu dev) to maximise mining power.

To optimize your mining range with CRT miner:
cf.
https://bitcointalksearch.org/topic/m.54565947
https://bitcointalksearch.org/topic/m.54575759

There are more questions about wallet and solo mining.
The wallet opens for a very long time, Windows 7, you need to wait a day for the wallet to start, I'm not talking about the long synchronization, the blockchain bootstrap does not ease the situation, the wallet indexes and opens blocks for a very long time.
On the VPS with ubuntu 16.04, I waited almost a week for full synchronization.
This miner GapMiner rev5.1 CRT Creation



No processor load. Why?
Here is another miner, and I understand that they cannot mine on the pool, only solo.



There are 2 cores, Vishera 4.2 GHz.
I started mining on 4 cores, nothing was mined in three days.
How long does it take at this hashrate to get a block?

Give me a few hours I will post a full gitian build process guide for the above 

Does this mean that I can find a programmer who will compile the source files for windows using gitian-building?
Will it be safe?
If yes, then I can find such a person through this forum.

And yet, there is such a block explorer service https://openchains.info/
Give them access to the daemon coins and they run for free  block explorer
I can on VPS run the Gapcoin daemon.
But this service has a drawback - you cannot view the balance and other data at the address.
Do need it?

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.

Cheers

Graham

(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

Graham

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 ^

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!

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 !
