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

[UsernameNumber7]

To
 Compile this, we need to tweek the Boost Program to the new parameters
inside the make file......‘boost::STATIC_ASSERTION_FAILURE<false>’

That was the last error I got, if you got the work around how to
re-write the gapcoin make file to use the new boost than I "hope" that
is the last step to building the QT wallet on debian/Gnu Linux


1)  Other problems were firstly the need to find the Berkely 4.8 database
 as it has been scrubbed from the internet and I read others say that
the newer Berkely DB are not compatible with the 4.8 wallet,dat files
which would be odd, but they have thrown every monkey wrench they can
find into anyone following Bitcoin development.  

I happened to find what looks like the only source still for Berkely DB
4.8, but I did not actually try Jonn9 direct download from Oracle site
for it.  

https://launchpad.net/~bitcoin/+archive/ubuntu/bitcoin/+sourcepub/4094733/+listing-archive-extra

That
 was the first problem, I had to un-install the newer version of Berkely
 DB as you can't install both........than install Berkely 4.8 and
Berkely 4.8++

2)  Maybe some OS already have it installed but Glib-2.0 dev also needs
to be installed.

3)  than we have to solve the Boost problem that needs solved...........

Than hopefully we can compile and build a QT wallet on Linux again

I think the biggest issue is the Berkely DB 4.8 if we cannot transition
to a newer version we will always have to manually have the backup of it
 and install it manually?

Well, the Boost problem was easier than I thought......

Go into the Gapcoin clone file/ SRC file/ open RPCRawTransaction.cpp

And change 1 line on line 299 cut and paste the new instruction

https://github.com/unitusdev/unitus/commit/5258735ad867b44eadf58eaf27a6639da43f81a0


Of course that did the trick after about 10 minutes it completed the make, but it still fails to build the QT file which should be done automatically, with so many things changed who knows.....Any Ideas? 

[UsernameNumber7]

Ok,
 IT WORKS!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!!

After Make

In Terminal

Cd Gapcoin

Cd SRC

Cd Qt

./gapcoin-qt

That should start your wallet from the terminal/ I assumed it would
build an execuitable QT, it is from Terminal.
I did gapcoin-qt from the SRC terminal and it pops up but stalls you
need to add the extra command Cd Qt than Gapcoin-qt to start the wallet
properly.



Gapcoin Unix build commands

https://github.com/gapcoin/gapcoin/blob/v0.9.2-gap/doc/build-unix.md

(When installing QT5 libqt5core5 needs to be libqt5core5a)  Just add the (a) into the line commands for QT5 install


Apparently Jonn9 had already planned Gapcoin to be used as a .Onion
server

https://github.com/gapcoin/gapcoin/blob/v0.9.2-gap/doc/tor.md

I looked over this, but making the wallet was first BitcoinFX can you
concur with those Tor instructions?

https://github.com/gapcoin/gapcoin/tree/v0.9.2-gap/doc

[UsernameNumber7]

Those



Instructions are in no particular order.......Lastly also Topmenu-GTK2  
needs to be installed to avoid the error when starting the QT wallet.




Coherently,

1(  Download and install Git

sudo apt-get install git    
sudo apt-get install synaptic
sudo apt-get install gdebi
sudo apt-get install pkg-config


2(  Clone into the Gapcoin from Command Terminal

git clone https://github.com/gapcoin/gapcoin.git


3(  Find the gapcoin folder once its done click, src click, find open
RPCRawTransaction.cpp click,

Change line 299 to

const CScriptID& hash = boost::get<CScriptID>(address);

Click Save and close

https://github.com/unitusdev/unitus/commit/5258735ad867b44eadf58eaf27a6639da43f81a0


 

4( Open synaptic again search Libdb and uninstall Berkely Db (if already
 installed newer version), search for glib2 and install glib2-dev at the
 same time for
uninstall Berkely DB   also search and install Topmenu-gtk2

5( Download the Berkely DB 4.8 from

Furthermore,
 I was able to locate the data directories inside Gnu/Debian and Ubuntu
by clicking the view hidden files inside the home folder........either a
 left click VIEW or a top header tab display click VIEW hidden files or
folders

http://bitzuma.com/posts/moving-the-bitcoin-core-data-directory/

This is used to delete the blockchain if there are errors or to download
 it seperately and copy paste in the blockchain using non-P2P nodes.

Also this is where back up of wallet.dat file is and to repaste it here
on a fresh computer install from a saved copy.

This type of information is hard to come by considering how important it
 is.  Windows it is easy but Linux uses hidden files and folders by
default....

hope it helps..............

@UsernameNumber7

Glad that you have managed to get everything set-up.

[BitcoinFX]

The new 'unofficial' Gapcoin Club website is now live.

- https://gapcoin.club

It's somewhat basic for now, although provides Gapcoin and the community with a fresh starting point.

The focus is currently towards maintaining and of course building on what we have.

I've added a basic guide for windows users to get started with CPU mining Gapcoin in the wallet.

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

The Gapcoin Club hosts all of the IP nodes mentioned in the guide and thus the network has increased its overall stability.
 
A guide for linux users should be online within the next week or so along with a new cloud mining guide.

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

I will be cloning the official Gapcoin repo. to continue with development and we have some options for new Gapcoin mining pools.
 
 
The target date for Gapcoin to attempt a new world record prime gap will commence from 21st Oct. 2017.  

[legday]

its 34% up since yesterday.

[UsernameNumber7]

well,

 working to see about the GapMiner compilation from Github.....

Running into Src/Evolution errors when trying to make........GapMiner
says it has a GPU Miner but I doubt anyone is using it since it can't
really be compiled maybe windows works I don't know?  But if someone has
 not migrated away from windows yet it only means they are cattle being
fattened up for the slaughter............

At least if you compile under Linux you can update the SSL Certs and parts for
Gapcoin automatically, but Windows user have to always use the same package that was
released from about 2 years ago.  When a Debian/Gnu user builds his
Gapcoin QT it compiles with the best available parts from the parts
list.  Windows is the same old backdoored parts list....that don't age
well........

But I do not trust Graphics cards, or much of anything computer related, this is more of an "attempt" to work around and hack through the "fog of war".  Fog of war is the conception from the German Military, from once physical contact is made it clouds the judgements from the good, and bad. 


I would wait till AMD at the very least develops on open source Kernal for their GPU drivers to allow Debian/Gnu to use it.  However open-source is not Libre, it will far outshine anything available today in terms of usability and "trust".  The current GPU kernals tend cause many computer instabilities once installed, and often times requireing re-installation all over again. 

[Milquetoast]

The starter of the thread j0nn9 wasnt here since a long time. Are there any active developer left or is this a realy dead coin. I like the idea of Gapcoin, but I think I make no sense to mine this coin whithout any activ develooper.

[UsernameNumber7]

well, I just got GapMiner to build, but I am not sure what exactly I did.  

Moved a test Miner to shift 75...............

Any Idea how to get the GPU part of the Miner working for GapMiner or is there a seperate Miner for GPU?

GAPMINER DEBIAN/GNU INSTALL INSTRUCTIONS

https://github.com/gapcoin/GapMiner

Open Synaptic

Search for and install things related to

jansson

curl and curl ssl

pthread

The other stuff should already be installed if you successfully built the QT wallet.

git clone https://github.com/gapcoin/GapMiner.git
  cd GapMiner
  git submodule init
  git submodule update

Jonn9 forgot the last step......................

with the Terminal open to cd GapMiner enter cd src/Evolution

and command

 git submodule init
 git submodule update

This should get you the C-Utils

Now go back to the terminal with Cd GapMiner

Command:

Make all

Check the folder in your home folder GapMiner and than bin folder to see if gapminer shows up and that is your execute program.

Now follow instructions how to set your config file for Gapcoin-QT and GapMiner

For GapMiner
https://github.com/gapcoin/GapMiner

And alternatively cd GapMiner/bin

./gapminer

That will drop down a list of other acceptable config terms that gapminer will accept.



When your ready to start your Miner

Terminal:

cd GapMiner/bin

./gapminer (...........................................ADD Your Configuration Terms Here..................)

to start

I'm not going to say "I'm an active developer" for Gapcoin, although I am trying to generate new interest in this project.

Finding a new fully competent developer is certainly on the to do list.

The Gapcoin network is stable, the although the wallet could use some feature and compatibility updates + new OpenSSL - Bitcoin v0.9.2 (which Gapcoin Core is built on) was actually a reasonable release with some necessary security fixes.

...

Which version did you compile ?

- https://github.com/gapcoin/GapMiner/

Pre-built static Linux binaries for the GPU miner are here:

- https://github.com/gapcoin/GapMiner/releases/

I don't think the CRT mining was working with GPU mining.

You might also find that the sieve runs on the CPU and that mining uses 100% CPU when GPU mining. GPU mining is only around 6x faster.

Gapcoin now has 5 8 addnode=.onion addresses for connectivity via the Tor network.

addnode=gapjxn4tu4gxmqxv.onion
addnode=gapqwfoecvhkoifb.onion
addnode=gap2nsvhispcyuw3.onion
addnode=gapr7miih6qnvpa5.onion
addnode=gapjp4zaoxeefepi.onion
addnode=gaptbn4uyvv7ln7d.onion
addnode=gap5eiwtcw35ympv.onion
addnode=gapxnu2mgche3y7v.onion

If you want to connect Gapcoin via Tor, then here is a gapcoin.conf client example;

Code:

listen=0
daemon=1
server=1
port=31469
rpcport=31397
rpcuser=gapcoinrpc
rpcpassword=YOUR_RANDOM_GAPCOIN_RPC_PASSWORD
proxy=127.0.0.1:9150
maxconnections=8
onion=127.0.0.1:9150
addnode=gapjxn4tu4gxmqxv.onion
addnode=gapqwfoecvhkoifb.onion
addnode=gap2nsvhispcyuw3.onion
addnode=gapr7miih6qnvpa5.onion
addnode=gapjp4zaoxeefepi.onion
addnode=gaptbn4uyvv7ln7d.onion
addnode=gap5eiwtcw35ympv.onion
addnode=gapxnu2mgche3y7v.onion
addnode=45.76.140.157

Note that the Tor Expert Bundle uses SOCKS port 9050 instead.

You can just connect the wallet via the Tor Browser Bundle (although it is not really advised for privacy as it will potentially effect the anonymity of browsing, but it will work). Instead you should use and configure the Tor Expert Bundle.

Tor (torrc additions) client only for TBB, example;

Code:

ClientOnly 1
SOCKSPolicy accept 127.0.0.1/8
LongLivedPorts 21,22,706,1863,5050,5190,5222,5223,6523,6667,6697,8300,31469

Note that you obviously need to start the TBB first (and keep it open / running) and then start the Gapcoin wallet. The reverse being correct for shut down.

LongLivedPorts is the 'default' TBB / Tor ports list + Gapcoin port 31469 - the default ports list is present to help ensure that the client does not stand out.

...

This information will be added to the new gapcoin.club website in due course along with a more up-to-date copy of the Gapcoin_blockchain.zip - however a fairly recent copy is available from cryptochainer.com

- http://108.61.216.160/cryptochainer.chains/chains/Gapcoin_blockchain.zip

Nice work BitcoinFX, together we can hopefully move this thing along........I am more and more impressed with Jonn9's work though.  The windows side is the only one that needs a "developer" otherwise Gapcoin is more advanced  compared to other shitcoins. 

My Debian/Gnu updated the SSL cert automatically when I built it. 

I am looking for the commands to start the GPU, I got the AMD kernal installed........

[BitcoinFX]

Indeed. Gapcoin is a solid crypto-currency with a useful PoW, unlike Bitcoin.

It also has an economic model to rival other crypto's, if we can start to build-up any kind of economy using GAP.

"The big improvement in comparison to Bitcoin is that instead of burning electricity for it's own sake, Gapcoins Proof of Work function actually does useful work by searching for large prime gaps - https://en.wikipedia.org/wiki/Prime_gap "

"Specifications:
PoW: custom, prime gaps
Block target time 2.5 minutes
Block reward proportional to the current difficulty
Block reward halving every 420000 (about 2 years)
Cap: about 10 - 30 million GAP
Difficulty adjusts every block and increases logarithmically (it will probably take years to get to 50)

Fair launch:
Gapcoin was not designed to enrich the early adopters or the coin creators! Unlike Primecoin, the more people that mine Gapcoin, the more coins per block will be produced. (Coin supply will increase logarithmically with the difficulty, this means it will grow in the beginning, but later, it won't change that much.)

There wasn't any premine!"

If the network hash power gets high enough then we do eventually stand a good chance at breaking the world record prime gap! Which would certainly be a news worthy event.

When Gapcoin did have a working pool, folks were mining only at the lower shifts. With a couple of new pools, some regained popularity and bulk solo miners using the higher CRT shifts, then we might stand a very good chance at a new world record and if not then the blockchain will certainly be full of useful mathematical data.

We already see regular connections from Universities across Europe, the US and Asia who are clearly interested in harvesting the math results that Gapcoin generates.

CUSTOM
 QT WALLET MINER CONFIGURATION TUTORIAL

It is possible to create our own in-wallet miner customized.  We can use
 the GapMiner as a test bed to try various sifts and shifts before we
generate our wallet.  We can do this with many different saved profiles
of generated wallet QT's.  Just by renaming them.  And using Terminal Cd
 Gapcoin1 or Cd Gapcoin2 /src/qt than ./gapcoin-qt to start up whichever
 wallet Sift we wish to Mine with.

This is by far the simplest solution.  

First go to home folder and delete the git Cloned gapcoin folder if you
have already built the QT wallet.

freshly git clone of Gapcoin


Find the gapcoin folder once its done click, src click, find open
RPCRawTransaction.cpp click,

Change line 299 to

const CScriptID& hash = boost::get<CScriptID>(address);

Click Save and close


in Gapcoin/SRC find and open Miner.cpp

scroll down

to the mining shift and mining sift and sieve information.  Input your
set paramaters based on your GapMiner trials.  Click save and close. (I
recommend only changing the shift at this point unless you played with
your own settings using GapMiner)

Finish the rest of the Wallet QT generation

cd gapcoin
git submodule init
git submodule update
./autogen.sh
./configure
make

Remember not to touch the .gapcoin hidden folder in Debian/Gnu.  DO NOT
TOUCH IT.  If you have already sync'd the blockchain and your wallet is
loaded this will not be touched at all by this operation.

If you want to generate a new custom wallet miner you need to change the
 git clone gapcoin folder and rename it to gapcoinshift45 or
gapcoinshift175 ect....just remember if you want to use one of them you
need to use in Terminal

Cd gapcoinshift45/src/qt

./gapcoin-qt

To start your wallet every time, but you will work off the same
wallet.dat file and same blockchain ect...........


Also be careful of Berkely Database upgrading automatically from 4.8 which will require a re-install and removal again of the newer Berkely database.  This will show up with ./configure part of the operation. 

[BitcoinFX]

@UsernameNumber7 Thanks! Useful input here, moving forward.

Don't forget;

https://bitcointalk.org/index.php?topic=822498.msg9295189;topicseen#msg9295189

setgenerate generate ( genproclimit ) ( sievesize ) ( sieveprimes ) ( shift )

Set 'generate' true or false to turn generation on or off.
Generation is limited to 'genproclimit' processors, -1 is unlimited.
See the getgenerate call for the current setting.

Arguments:
1. generate         (boolean, required) Set to true to turn on generation, off to turn off.
2. genproclimit     (numeric, optional) Set the processor limit for when generation is on. Can be -1 for unlimited.
                    Note: in -regtest mode, genproclimit controls how many blocks are generated immediately.
3. sievesize        (numeric, optional) Sets the size of the prime sieve.
4. sieveprimes      (numeric, optional) Sets the amount of primes used in the sieve.
5. shift            (numeric, optional) Sets the header shift.
                    Note: sieve size can only have 2^shift size.

Note: shift also should be in range [14, 512]

Shift, should be the most sensitive parameter, because it controls the bit size of the primes.
Second would be sieve primes.

...

I've run some tests for the built-in wallet miner. Shifts above 28 seem to have a lower performance when CPU mining.

The most optimal range is seemingly the 25 or 26 shift range. I think that the 26 range has a higher gaps per. day / primespersec ratio.

2^25 = 33554432
2^26 = 67108864

So,

Code:

setgenerate true -1 33554432 900000 25

or

Code:

setgenerate true -1 67108864 900000 26

Generation is limited to 'genproclimit' processors, -1 is unlimited. ^^ i.e. Num CPU Threads

*snip*

I am looking for the commands to start the GPU, I got the AMD kernal installed........

The next gapcoin.club guides will be for GPU mining, an advanced guide for cloud mining (security), compiling the GUI for ubuntu 16.04 LTS and a how to for Gapcoin on Tor.

If you look back in the thread there are some settings / commands for GPU mining.

...

As much as its great to have the Gapcoin network (and mining) fully decentralized at present, we are going to need a pool or two up and running to stand the best change at hitting a world record prime gap.

My main focus at present is a new working pool, some basic promo and outreach to the mathematics / academic communities.

Interested mining pool operators and developers are welcome to PM me.
