Title: [GRP] GRouPcoin
Post by: markm on March 09, 2012, 12:30:21 PM
I have applied the BIP-30 patch to groupcoin, latest source code is at

https://sourceforge.net/projects/galacticmilieu/files/GRouPcoin/

It seems we never did get around to applying the merged mining (as aux chain) patches to groupcoin-qt so currently wxWidgets is the only GUI available, it is right in there with the groupcoind in the groupcoin-09-Mar-2012.tgz archive.

What is GroupCoin all about exactly? How's this different from the other alt chains like SC,i0 coin,GG etc?

According to the readme file


Groupcoin is the precursor to devcoin, in which we tested
some ideas to fall back on in case we could not do what
we wanted devcoin to do.

Devcoin was described at

https://github.com/Unthinkingbit/charity/wiki/Devcoin-Description

but the description has apparently since been moved to

http://www.devtome.org/wiki/index.php?title=Devcoin

Yes, exactly, GRouPcoin is what we built on the way to creating DeVCoin. We tried some approaches toward how we thought we might be able to do DeVCoin, then once we settled on how to proceed we went ahead and made the actual DeVCoin.

Since the things we had been trying were things that turned out not to work, they were removed or turned back off, leaving GRouPcoin as just a simple inflation-forever coin, that is, a coin that keeps making 50 coins per block forever.

It also has the difficulty adapting fixes various coins adopted after seeing namecoin get left at high difficulty for months by being abandoned by miners, and the timetravel fix that prevents the timetravel exploit.

So it is just a nice simple example of a coin that keeps making new coins forever, which some people once upon a time thought might be better than designed-in deflation. I guess the people who used to argue against deflation, in favour of some kind of forever-minting coin like this one, maybe weren't really all that serious in their proposals since they do not seem to have made much or even any effort to actually pursue the experiment to see whether in fact not building in deflation is better than having deflation designed-in.

Nonetheless the experiment continues, and the coin is also being considered by the various Repossession corps in various games for adoption as their own currency, which they would then tend to refer to as Galactic RePo coin (also known as General RePo coin)  instead of GRouPcoin, retaining the GRP symbol but re-purposing it.

-MarkM-

EDIT: For the Repo corps to use an inflationary coin is kind of ironic given that the existence of such corps in the first place is itself a move against the inflationary nature of new-player-startup-stuff in games, whereby games can be spammed-full of free stuff simply by having lots of new players joining the game and being automatically provided with various startup items and/or resources and/or places/villages/planets/etc.

So is Groupcoin still running?  Is there an exchange, pool, gui, or other things available for people to easily get involved in mining/owning/using Groupcoins?


Title: Re: GRouPcoin
Post by: markm on April 11, 2012, 02:34:40 AM
It is still running, but the exchange is an Open Transactions server and Open Transactions is still having some growing pains, another round of deep improvements to the code that might make all of the existing stuff we set up in the exchange have to be re-done from scratch. We are still trying to work out whether our data will need re-doing or not, as the latest round of changes are still in progress.

Once it is working, Open Transactions will be a great platform for trading all the cryptocurrencies and also a whole bunch of shares in various corps. It is a general purpose platform that can do currencies and shares and eventually also other assets such as real-estate. So although it has taken many months already working with it, the work should be well worth it once we finally get through al lthe changes we found had to be done to make it a realistic platform.

If you want a GUI, you can compile with wxWidgets, same way bitcoin used to since it is based on bitcoin code. Most people using it are just really using tokens of it, through various kinds of bank-like systems such as their clan accounting or even, for clans that don't have their own cryptocoin daemons set up, a clan account with some clan or nation or planet or whatever that does have a daemon or that got an account on the Open Transactions server during periods when it was up and running, or that use person to person accounting in any of the various MUD or Crossfire or whatever servers.

No, it is not pegged to fiat at all.

In some games though some of the players seem to generally assume it ought to be worth 1,000 DeVCoins since that is how many more DeVCoins get generated than GRouPcoins. The fact that mining them is actually much easier many players kind of shrug off as well y'know, the people who mine the gold for goldpieces or the silver for silverpieces or the copper for copperpieces probably make a markup too, its what parts of gaming interest you, you wanna run around killing critters and taking whatever kinds of coins or jewels or whatever they happen to have, or become some kind of computer geek to rig up your home machine to mine for you? Heck many players don't even run 24/7 scripts to train up characters or forage for resources etc. Many don't even run triggers to have them automatically eat when hungry, apply healing aids when wounded, etc. Its all in what aspect of gaming you happen to be into.

You lot probably don't even want to have a material body in the game subject to having some assassin sneak up behind it cosh it and steal your coins while you read the stock ticker. Others would prefer to pretend to read the stock ticker while waiting to pickpocket actual traders who come read it looking to trade. Different games for different folks...

Right now GRouPcoin and DeVCoin are looking better to most players than most cryptocurrencies simply because there aren't yet a lot of players offering decent stuff for sale for other currencies. With GRouPcoins or DeVCoins you can buy good gear, so they are "worth more"... Other currencies' advocates just don't seem to be into gaming maybe.

The long delayed debut of GRouPcorp (https://bitcointalk.org/index.php?topic=101342.0), the GRouPcoin-promoting Corp along the lines of DeVCoin's DeVCorp (https://bitcointalk.org/index.php?topic=61407.0), is finally coming back on track.

The initial offering was 1,000,000 shares at one GRouPcoin each, however only 22,000 were bought before we ran into a snag: it turned out that the issuer account for digiGRouPcoins (dGRP) on Digitalis Open Transactions server (https://bitcointalk.org/index.php?topic=53329.0) had gotten "out of sync" way back when during one of the major upgrades of the Open Transactions software, preventing us from issuing any more dGRP tokens.

This not only led to people not being able to receive these tokens, with which to buy shares, but also it interrupted me in the very process of recording the assets of the GRouPcorp Corp; all the asset valuation stats at http://galaxies.mygamesonline.org/digitalisassets.html have been showing a ridiculously small value for sGRP (GRouPcorp shares) because I had not gotten around to recording the fact that the Corp still owned 978000 of its own shares.

I have now corrected that omission, so the next run of the valuation routines should show the correct valuation for those shares.

However the issuing account for dGRP is still out of sync as with the further upgrades of the Open Transactions software the old sync script we used in the past to correct out of sync accounts is now out of date so we are waiting for an updated version of resync before we can resync the account and issue people the dGRP tokens they have been waiting so long for.

https://sourceforge.net/projects/galacticmilieu/files/

It is the same as the groupcoin-09-Mar-2012.tgz that it replaces, except for the addition of a new checkpoint and

application of the important bugfix disclosed in the recent [Full Disclosure] CVE-2012-2459 (block merkle calculation exploit) (https://bitcointalk.org/index.php?topic=102395.0) thread.

The long delayed debut of GRouPcorp, the GRouPcoin-promoting Corp along the lines of DeVCoin's DeVCorp, is finally coming back on track.

Can you please explain, is this just a game or do these corporations actually do anything? I've been reading your messages for some time, but still I cannot understand.

I understand that play assets are not fundamentally different from 'real' assets, but the difference is in fundamentals: is there any activity other than posting about it on forum? So, well, is this an economy in itself, or is it integrated with outer world?


Title: Re: GRouPcoin
Post by: markm on August 22, 2012, 08:12:25 AM
GRouPcorp hasn't really done anything yet.

DeVCorp though was instrumental in getting a whole bunch of stuff done, mostly through the General Financial Corp which DeVCorp was the main driving force behind.

As you said there really isn't much of a line you can draw between "real" and "non-real" currencies, contracts, trades, deals, and so on. In many ways the whole edifice of "unit of account" games known as "finance" is kind of unreal.

People who get right into some particular activity might find endless fascination in it, but one thing abstract finance seems potentially to offer is a way for all kinds of people to interact with all kinds of stuff in totally abstract ways where all they care about is some particular market, whether it be dollars for magic swords or pineapples for spaceships or whatever pair of assets catches their interest, possibly only because of the ups and downs of its chart without any interest whatsoever in what the actual things are whose relativity in that market has caught someone's attention.

Thanks to DeVCorp, a whole bunch of compound interest denominated in DeVCoins is coming the way of various entities; the main reason GRouPcorp has not done much the same for GRouPcoin yet is I have not been able to issue people their groupcoin tokens yet...

-MarkM-


Title: Re: GRouPcoin
Post by: markm on October 07, 2012, 10:49:40 AM
It turned out there was nothing fundamentally wrong with the GRouPcoin issuing account, I simply had not realised the resync utility operated on a per nym basis thus it had never actually been run for the GRouPcoin-issuing nym since way way back when some major updates and changes led to some old accounts getting out of sync.

So I have now been able to issue more dGRP (digiGRouPcoins) onto the server and once they are divvied up to their destined recipients GRouPcorp (https://bitcointalk.org/index.php?topic=101342.0) will be able to start selling its shares at last and thus have some capital with which to start doing whatever it is going to be doing.

Just thought it might be worthwhile to remind folks that this coin is still chugging along, and can still be merged-mined alongside bitcoins, namecoins, devcoins, ixcoins, i0coins and coiledcoins. It seems a few more merged-miners have picked up on that fact recently but so far its difficulty is still well within the reach of small at-home GPU-miners...

Also with the advent of the new Ripple, Open Transactions is no longer the only "exchange" available for it...

Something seems to have been going on with this coin recently, the plot

http://galaxies.mygamesonline.org/plotgrp.html

shows it has climbed rapidly.

Also its value per coin climbed back up above that of DeVCoin not long ago (though it is not the only coin that happened to).

Main menu of such and related plots and tables is at

Has GRouPcoin been added to a merged mining pool recently or is it just that merged mining privately is becoming more popular?

GRouPcoin's difficulty is up to 292949.03423883 now which is way higher than it was like hmm yesterday, maybe? Last few days sometime anyway.

How to mine GrouPcoin?

Using the daemon is probably easiest, as trying to compile the wXwidgets GUI was hard way back when and probably much harder now that maybe wXwidgets that one gets with one's distro is a much newer version than the old original bitcoin was built with. heck bitcoin was already using an older version than was current when i first came across bitcoin.

So unless you want to wrestle with ancient wXwidgets, the daemon would be the way to go.

I did upload though a copy of the specific wXwidgets I used.

Here are my compilation instructions, because this thing is shipped with the crappy makefiles from early bitcoin releases.

Get fixed makefile.unix from http://pastebin.com/ncnG57t8

BDB_LIB_SUFFIX=-4.8 BDB_INCLUDE_PATH=/usr/include/db4.8 make -f makefile.unix groupcoind

Your bdb include path might be different depending on your installation - but if you compiled any recent *coin you should already know what to do with it. The most important part is to ask for groupcoind, as the wxwidgets one is even more of a nightmare to compile.

If that helped you, send your first groupcoins to 2huz72a79xir7cFEnNKvQN9KeBmGqRRUr1w ;)

So how do you compile as I tried in windows using wx an no clue what to do lol.


Title: Re: GRouPcoin
Post by: markm on August 07, 2013, 02:41:15 PM
I wouldn't bother with the wxwidgets version, now that I0Coin has been updated the rest of the merged mined coins can rebase on the I0Coin code and all get nicely up to date plus have the memory fixes.

Hopefully GeistGeld will be next to update since it needs the memory fixes as much as I0Coin did or more, but then hopefully CoiLedCoin, GRouPcoin and so on will all follow...

+1 for a windows version for my old Win XP. I´m not ready for Linux yet. For the beginning I would be satisfied with any kind of address-generator, so that I can use an address for merged mining in Bitparking-Pool. Any paper-wallet-creator or something in the net?

DeVCoin uses bitcoin addresses but GRouPcoin uses ones slightly offset I think, so that they typically start with a 2 instead of a 1.

Though maybe that is just my luck of what addressess I have generated if maybe bitcoin/devcoin addressess can sometimes start with a 2 ?

I suspect though that with GRouPcoin we prototyped how we would go about changing the address system but then ended up deciding that for DeVCoin proper it would be better to use BiTCoin addresses to make it easy to use people's existing donation addresses.

Dear markm,

yesterday I inserted into BitParking just my BitCoin-address, as I have it´s private key. At later times, when I converted to LINUX (or there came out a Windows client - whatever happened earlier...;-), so I planned, I could make use of the GroupCoins (which are already more than 10 now - BitParking displays that number).

So far my idea.
But if the GroupCoin prefixes with 2, then its useless. Maybe somebody wants to change my newly to create GroupCoins into Devcoins? Then I just put in your GroupCoin adress, and you can send some (how many?) Devcoins for exchange. Just my humble idea. Don´t take this too serious, I guess that GroupCoins maybe don´t have any value at all.

Anyways, I would prefer to keep them by myself if I just could...

All coins' addresses are derived from private keys, if you have the private key you can from it create addresses for all possible coins' address types, they are just different prefixes resulting in different checksums, there is code somewhere, some app, a python script maybe or something like that, that can provide you with addresses for all coins all from the exact same private key, heck it might not even need a private key it might be able to directly convert any address into any other coin's form of the address.

Actually they might be derived from public keys not from private keys come to think of it.

Vanitygen can handle any prefix too, so you could use vanitygen to create an address for any coin.

If you don´t need your GRouPcoins, you can use my address ;-)

Sorry to revive such old thread but since i mine at bitparking and they allow mining groupcoins i wanted to try it. There is not windows wallet right? And no exchange for it too?

I tried to install the linux wallet but rpi only tells me that the tgz cant be recognized. So i dont know how to install (linux noob so far...).

I wondered, when i have groupcoins and i0coins... where to exchange? It looks like no exchange is trading it and i guess it might be hard to sell it to a random person in some irc or so. How its done?

Ok, didnt know that. Then is there an alternative? At least vircurex doesnt offer such addresses. Is there a wallet? I would want to sell the coins anyway. And theres the next problem. Where to sell coins that arent traded? Will someone buy them at all?

Link? If you mean the first posts link with the 2 versions i downloaded it but my rpi cant extract it because it doesnt recognize the archive. I dont know how to install this on the rpi to get an address.

I yesterday tried installing the linux wallet on linux mint. We couldnt get it to work. I simply didnt find how to install or start anything. And the docs are for bitcoin wallet it seems.
I wonder how others get it to work. I mean you need such a wallet since i dont know a way to store or transfer groupcoins another way.

Compiled and is running fine here on a Ubuntu Server 12.04.2 LTS.
Here are the steps I took (IIRC):

Get the source from the 1. post and unpack the tgz to a dir of your choosing and cd into it's src dir.
There replace the old makefile.unix whith the one from pankkake's post (thanks for that btw mate :) ).

Then issue (I unpacked the sources tgz in ~/coin):
Code:
sudo apt-get install libdb libdb-dev libdb++ libdb++-dev libssl-dev build-essential autoconf automake make nano
cd ~/coin/groupcoin/src/
make -f makefile.unix groupcoind

This should compile groupcoind without errors (if not, post your output please).
Next create a groupcoin.conf file (you can use mine, don't forget to set a username and password although only localhost connections are allowed -> http://pastebin.com/P9v9Lp1L (http://pastebin.com/P9v9Lp1L)) and start the groupcoin daemon:
Code:
mkdir ~/.groupcoin
nano ~/.groupcoin/groupcoin.conf
./groupcoind &

Now the daemon should run in the background and start to make connections and dl the blockchain, give it a min and issue:
Code:
./groupcoind getinfo

You should get some output of the status of the daemon.
Now, to display your grc address issue:
Code:
./groupcoind listreceivedbyaddress 0 true

To stop the daemon issue:
Code:
./groupcoin stop

Well, all pretty straightforward and for all other commands you can consult any of the *coin docs (bitcoin, namecoin, ...).
If you run into trouble, post your output.
Good luck!  ;)

Thanks for the tutorial. Im new to linux, only made little things till now with it. I now run linux mint on virtualbox.

I tried your command:

sudo apt-get install libdb libdb-dev libdb++ libdb++-dev libssl-dev build-essential autoconf automake make nano

Its working something but at the end its saying: E: Unable to locate package libdb

I copied your command again from your post to be sure i didnt made an error but it remains this way. When using make then it tells me:

also saved the address.dat <<-- whats this file? not in other coin data dirs....

I understand not everyone can be a "penguine" and even I am faaar from an expert. But everyone should! *cough*snowden*cough*  ;)

Anyhow... yeah the errors should have been the result of a wrong package name.

Try:
Code:
sudo apt-get install libdb++-dev libssl-dev build-essential autoconf automake make nano

IIRC (there it is again) the C++ libs of BerkeleyDB should suffice. If you still get libdb errors try:
Code:
sudo apt-get install libdb-dev libdb++-dev libssl-dev build-essential autoconf automake make nano

The other compile errors should be a result from apt-get bailing out because of the missing package.

Hm, with the new "makefile.unix" it should compile with "USE_UPNP:=-" hence disabling the use of UPNP libs.

Heh, disregard my previous babble, in the new makefile the "ifdef USE_UPNP" part is commented out, so it will always compile without upnp.

Yeah listen to K1773R, seems there's a reason for his avater :) this should work even with the original makefile (did not test it though)...

I then deleted the new makefile and reused the old but the errormessage remains. Does the files have to be in a special directory? Im using Mint 14 in VirtualBox if that matters.

Regarding Snowden... im not sure Linux will help there. When the NSA cant be stopped by the TOR-Network anymore, then reading that Germany is the country the NSA is working the most with and then read that Germany is the first country that literally legalizes Bitcoins i had to think of a connection. I mean who is Satoshi Nakamoto at all? He created a currency that is a party for agencies... Of course thats a conspiracy theory only. :)
The only possible security gain linux might give are missing backdoors and vulnerabilities. Which is a serious issue for sure when people dont have their money at a bank account anymore but instead in a wallet on their harddisc. I see many tears coming from that fact in the future.

Seems the default make target is the wxwidgets GUI not the groupcoind.

Building with the specific ancient version of wxwidgets that old code used is hard, even if you grab the exact right version of wxwidgets.

Trying specifying to make groupcoind or maybe even bitcoind if makefile wasn't hacked to change name of target from bitcoind to groupcoind.

Now that i0coin has been updated so nicely it is time anyway for all the other merged coins to update themselves based on the new i0coin code.

Im not sure what you say but will you change makefile so that it works?


Title: Re: GRouPcoin
Post by: markm on September 01, 2013, 02:45:39 AM
Mine already worked, I just think one had to say bitcoind instead of groupdcoind as what to build.

The GUI might not be feasible to build anymore due to even if you manage to get the correct ancient version of wxwidgets that in turn might have depended on ancient versions of everythig else on your system resulting in gosh knows how many things you might have to use ancient versions of in order to get that ancient wxwidgets to work.

Basically groupcoin is a daemon-only coin as far as I know, unless someone does want to wrestle with that ancient wxwidgets GUI system.

Just make sure to mention you want the daemon compiled, that is, bitcoind, or if someone has hacked your copy of the makefile to change the name from bitcoind to groupcoind, then groupcoind.

I never changed that name due to there are many makefiles for many systems and I did not want to imply they all had been made up to date by hacking just that name when, for all I know, tons of other things in other makefiles might also need changing. I figured best leave the original bitcoin makefiles so people can see that they have not been changed so they can figure out that whatever they do to such old makefiles for bitcoin to make them work the same updates will be needed in these to make these work.

So I just rename bitcoind to groupcoind after stripping it after making it before moving it to /usr/local/bin manually for use.

Also I personally do not even use makefile.unix because it lacks the -mt suffix on the boost libraries and it doesn't force use of my custom openssl that includes elliptic curves, so for all coins first thing I always always always have to do is copy makefile.unix to makefile.fedora15 or makefile.fedora16 or makefile.fedora17 or whatever version of fedora I am up to by then and hack it to tell it about the boost libs suffix and my custom openssl because fedora deliberately leaves elliptic curves out of its openssl packages. For some coins I also have to tell it to be permissive about the order in which declarations happen, because the compiler on fedora is strict so doesn't like the code of some coins, at some versions of the coin. So in general, you might well need to make a custom makefile for your specific version of your specific operating-system.

Some versions of some coins I have sometimes also had to add -ldl too to make it link libdl, as some versions of some coins have sometimes failed to link because that lib was not specifically mentioned. The linker usually says that what is causing the error is in that lib so when that lib needs adding it is made clear that is the case by the error message given by the linker, on my system. I dunno if all distros of all operating systems have linkers that helpful though. I guess whatever version of whatever distro makefile.unix was originally created for some other lib already causes it to include libdl without the makefile having to mention it, or maybe does not use libdl so does not need it or something. Need for it seems to vary from coin to coin and/or version-of-coin to version-of-coin over the years.

SebastianJu, I also encountered the issue you're facing.  Try:

Turns out I needed some more items to build successfully:

Code:
sudo apt-get install libboost-system-dev libboost-filesystem-dev libboost-program-options-dev libboost-thread-dev libglib2.0-dev

It appears to have built groupcoind successfully now.  It's downloading blocks.

Is there a seednode for the "new" coin, or can someone throw me some peer IPs? I've compiled the client, debug.log says it's connecting to 142.68.82.127, and then...nothing. It doesn't report connect success or failure, nor is it trying other IPs. Apart from a wallet.dat flush that's the last thing reported in debug.log in the past 12 hours. Why isn't it persisting in trying to connect?

Been about 3 days now, debug log has not changed since I posted the above. The client is running, but it's not trying to connect.

Anyone got some peer IPs I can put into my conf to try to get it kick started? groupcoin is the only thing holding me up from opening a new account on bitparking.

Post by: markm on September 19, 2013, 02:33:58 PM
All the merged mined coins except I0Coin need new code to deal with the fact that merged mining eats more RAM, faster, than non-merged mining.

The faster a coin spits out blocks, the faster it runs into the problem of it using huge amounts of RAM.

GRouPcoin is a relatively sedate coin, with ten minutes block timing target if I recall correctly, so it is less urgent to update GRouPcoin than it is to update those merged mined coins that have faster average time between blocks target.

Presumably GRouPcoin will get done eventually, it is just not the one in most-urgent need right now.

Also, once it gets onto exchanges then maybe developers will be more interested in bounties denominated in GRouPcoin thus more responsive to the needs of GRouPcoin users who desire work done on the coin and have coins to reward developers for doing the work.

Title: Re: GRouPcoin
Post by: almightyruler on September 20, 2013, 07:39:13 AM
FWIW, groupcoin is already consuming 1.3GB worth of RAM on my *nix box. Only 55MB of that is actually "paged in" which makes me think that most of the data structures held in memory are very rarely used... so 95% of the allocated memory spends most of the time swapped out to disk. I can see this also causing problems because most typical *nix systems will probably not have huge amounts of swap. In my case, groupcoind, one single process, is using 1.25GB of swap, which is about 32%

Is there some way to streamline the client so it keeps those structures on disk instead, rather than consuming RAM/swap?


Title: Re: GRouPcoin
Post by: markm on September 20, 2013, 07:55:25 AM
Yes, that is what the latest I0Coin does. All the other merged mined coins need to be upgraded using that new code.

Hopefully GeistGeld first as it won't even run on my 8 gigs of RAM machines anymore since some time now.

I compiled the daemon from the source linked in the OP of this thread. It seems to be working fine.

It's kinda scary to use such ancient code now. It will not eat all my RAM, all CPU cycles and will not force my PC to jump over the window? :P
Is there any active development going on this coin now? :)

The plan is to upgrade it to the new code that I0Coin uses, however which merged mined coin gets updated first likely depends on the perceived reward; now that this one is on mmpool its difficulty has skyrocketed, probably too soon for the guy who came up with the new code to have mined a lot of these coins at low difficulty.

So I would expect whatever coins he is/was able to pick up at low difficulty might be the soonest upgraded simply because the more he has of a coin the more he stands to gain by upgrading it.

Mind you, I0Coin has been going down on Vircurex lately, so maybe even taking the time to mine a lot of coins before upgrading the code might not really pay all that well if other coins perform like I0Coin once they do get on exchanges.

Presumably mmpool users are steadily accumulating coins though, so maybe one of these months or years or whatever someone will decide they have a large enough stash that getting an upgrade done would be worthwhile...

Most of my players that have been snapping up merged mined coins the last few years do not use clients themselves, they just book-keep the things as just more in-game possessions kind of thing, hoarding them just like they hoard magic swords or mithril or whatever else.

Here are my compilation instructions, because this thing is shipped with the crappy makefiles from early bitcoin releases.

Get fixed makefile.unix from http://pastebin.com/ncnG57t8

BDB_LIB_SUFFIX=-4.8 BDB_INCLUDE_PATH=/usr/include/db4.8 make -f makefile.unix groupcoind

Your bdb include path might be different depending on your installation - but if you compiled any recent *coin you should already know what to do with it. The most important part is to ask for groupcoind, as the wxwidgets one is even more of a nightmare to compile.

If that helped you, send your first groupcoins to 2huz72a79xir7cFEnNKvQN9KeBmGqRRUr1w ;)

Hope you don't mind, I'm abusing your groupcoin wallet address for the Bitparking pool.  ;)

Edit :
groupcoin Paid 0.02477568 to 2huz72a79xir7cFEnNKvQN9KeBmGqRRUr1w

Until recently, GRouPcoin was mostly used by groups, such as guilds, clans, gangs and so on, bunches of players working together.

So most never even used the satoshi-client at all, instead their guild or gang or whatever (their "group") would have an account on the Digitalis Open Transactions server and maybe for some groups, the group might also have some kind of group banking system set up somewhere, maybe even on Tor or i2p, maybe running something like Cyclos.

Some "groups" tended mostly to use in-game currencies in the various games, leaving the holding of blockchain based coins and such to the clan/gang/group "officers" to hold as basic behind the scense collateral for the group as a whole.

So maybe if you are not a compling type of person you could check around in your "group" for someone who is, or form a "group" and try to attract someone into the "group" who likes to do nitty gritty financial program type stuff, or even maybe try to join a group that already has some kind of banking/finance stuff set up for its members...

If groups do that with groupcoin. Isn't there an arbitrage opportunity by mining or buying GPC? How do they value the GPC high enough to avoid arbitrage?

Groupcoins are a currency traded at open transaction server digitalis. At least the owner claims that this currency is used for a MORPG or so. But till now i spent a lot of time to make this software run to trade my groupcoins but i failed only till now...

Dunno what you mean, but generally in the game(s) one just uses the "price list", much like when you go into a branch of your bank and buy or sell foreign currency; though maybe I am way out of date, as I am recalling from decades ago my bank would just look up the rate for USD versus CDN or whatever, not go log on to some forex sites and check for arbitrage etc.

Basically there are a bunch of tables and plots at http://galaxies.mygamesonline.org/digitalisassets.html and the latest figures added to them get put at http://galaxies.mygamesonline.org/latestrates.inc which is formatted suitably for use as an include-file in shell scripts and such.

For example these latest rates figures were used in a bunch of market-making scripts that would add or subtract one two or three percent or whatever to make offers on three scales of the Open Transactions server's markets. Actually you lot would likely even think the way those scales were done is kind of the opposite of what you are used to since the larger the scale of the market the less the markup or markdown, so that to get the best prices you would buy in bulk. So for example someone could buy something in lots of one million and break that up into lots of one hundred throusand or even ten thousand to sell at a profit on a smaller scale market. Sort of like bank rates or nation to nation rates versus wholesale rates and retail rates or whatever.

So basically when you look at http://galaxies.mygamesonline.org/latestrates.inc bear in mind it is a middle of the road figure, sellers would mark it up one, two or three percent, or maybe more depending on relative scale of the assets of a pair, and buyers would mark it down, so typically you'd be offering to sell for more than those prices or offering to buy for less than those prices and how much more or less woudl depend on the scale of the market, basically you'd be asking more for screwing around with just hundred-lots or thousand-lots than for making substantial trades at larger scales.

Also bear in mind that the Digitalis server only uses integers, shares or coins are all the same, commodities measured in integers, no decimals/fractions. So in addition to the markup or markdown then also there would be rounding to be a price in integer number of this per integer number of that.

The whole numbers even for currencies is not only to stop acting like currencies are somehow magically different from shares or commodities but also because in the kinds of games a lot of players were used to one uses whole copper pieces, whole silver pieces, whole gold pieces, whole platinum pieces type of coinage not "pices of eight" as in chopped up little fractions of coins. So basically this way we get all assets to be similar in their integer wholeness whether whole shares or whole coins or whole porkbellies or whole pallets or containers or shiploads of porkbellies.

Windows wallet people!

I did the VM. You will need to give 2 GB of RAM to be safe, though it has a 2 GB swap partition to allow for lower.
It is shipped without a wallet.dat, meaning that it will create a new one on the first run.

It was built with VirtualBox, but the OVA format should be importable with by other virtualization solutions.

Beware, groupcoind is very slow to start, even if I provide the VM with an up-to-date blockchain.
The config file has an addnode line referencing a fast server of mine.

There seem to be no dumpprivkey command, if that's what you are seeking.

Why not. I'm not sure I'll run it forever, this is taking my time for little gain. From the log it seems that the client is looking for IPs using the IRC method; which is probably removed (or at least disabled) in the i0coin code. You should at least provide more IPs.

Original version increases nTargetTimespan for every GetNextWorkRequired with block < 9500. 
This is used in some modulo operations later which I'm guessing eventually result in a div 0 after it overflows.
Also, couldn't see where it would be set back to 1 day on block 9500, without restart?

Also, couldn't see where it would be set back to 1 day on block 9500, without restart?

For any block earlier than 9500 nTargetTimespan is 14 days, 1 day thereafter.
It's exactly what my code does, the same code is used in old client.
Code:
unsigned int static GetNextWorkRequired(const CBlockIndex* pindexLast)
{
    const int nSmoothBlock = 9500;
    const int64 nTargetSpacing = 10 * 60;
    int64 nTargetTimespan = 24 * 60 * 60; // one day

    if (pindexLast->nHeight < nSmoothBlock)
        nTargetTimespan *= 14; // two weeks
    int64 nInterval = nTargetTimespan / nTargetSpacing;

Actually, KrLos, if you read THIS VERY PAGE, you'll see that there is now an updated version (though experimental) with a more recent bitcoind/bitcoin-qt base.
And it seems to work well, though I'd appreciate some feedback  :)
After all I could move on to other merge mined coins to update their clients.

Had floating point exceptions when downloading full blockchain.  Can't be bothered forking in github but here's a patch:
Code:
--- a/src/main.cpp
+++ b/src/main.cpp
@@ -1115,8 +1115,8 @@ unsigned int static GetNextWorkRequired(const CBlockIndex* pindexLast, const CBl
     if (pindexLast == NULL)
         return nProofOfWorkLimit;

-    if (pindexLast->nHeight < 9500)
-        nTargetTimespan *= 14; // two weeks
+    // prior to block 9500 2 weeks.. daily after
+    nTargetTimespan = (pindexLast->nHeight < 9500) ? 1209600 : 86400;
     int64 nInterval = nTargetTimespan / nTargetSpacing;

Only quickly tested daemon on ubuntu 12.04 x64 but seems to work.
Well it should be equal, there's no floating point math used.
Do you have any logs?

Sorry for flogging a dead horse but not quite...   

In the new fork, nTargetTimespan is global (i.e. will be multiplied by 14 every call, and eventually overflow).  If the above snippet is original client, it is local and so will behave as expected.
Am guessing it is global now as was referenced in some other function/s, otherwise making it local would have been the better fix. 
You might want to check if mutating the value on the fly will affect any other usages of it too.

I'm assuming we are both looking at the same code, branch i0coin-0.8.x was default in git?  If not my humble apologies.

I just recently started merged mining on bitparking so I had to get a groupcoin wallet, I did get the GUI version to compile. Although it seems that it was been switched to Qt4 instead of wxwidgets because that is what it linked against in the make file.

My question though is that the groupcoin wallet has downloaded all the blocks it says are on the chain but its still 44 hours behind.... so does this mean that a block hasnt been created for over 44 hours on the groupcoin chain?

Does this apply to the daemons?

As I recall there is an input verification in the GUI that one needs to change to make address in the GUI work right, when we first made GRPcoin and DVCcoin we discovered that.

Other than that well maybe compare the code of the two versions see if they treat addresses differently?

Post by: markm on March 30, 2014, 03:43:14 AM
I kind of hope it does not get onto an exchange for some time yet, because even though it is way higher difficulty its difficulty could go up even more once it is on an exchange, due to more miners merging it or pressuring their merged mining pool operators into adding it to their merge.

Maybe though it is already difficult enough that the time has come to stop quietly building up a stash at low difficulty, bite the bullet and live with it being hard to mine...

Afterall there are still CoiLedCoin and GeistGeld for the merged miners who like to build up a stash before a coin gets onto any exchanges and into large public pool merges. :)

I noticed today, in setting up all my coins at home (having been forced to shut down my p2pool I had for merged mining out on the net) that my groupcoind uses tons of RAM, even more than the "dirty fix applied" geistgeldd I am using.

SO I googled and came across https://github.com/RoadTrain/groupcoin

I just started it now. Unlike what I had been using (off my sourceforge download site, not github), this one uses leveldb. Its binary, stripped, is half the size of the stripped binary of what I had been using, though that might be mostly to do with what libs are static/dynamic.

It uses tiny RAM, like other fully fixed (as opposed to dirty-fixed) merged mined coins.

I have written to mmpool admin to check what he is using, as I cannot test merged mining currently being still in midst of setting up everything at home.

No website-type exchange ever had it, I am pretty sure.

All we had was my Open Transactions server, which is still not a lot of use to normal folks since "Open Transactions for Grandmas" project seems to have gone on back burner...

...And a change in the internals of Open Transactions also has caused all contracts and nyms and accounts to go obsolete, so currently only ancient clients can even access the stuff.

Cinnamon, did you use RoadTrain's repo?

Also, as its not on any exchanges, please please lets use GRP (as I keep hinting by typing GRouPcoin), not GRC.

GRC for GRouPcoin is about as pathetic as BQC for BBQcoin. GRP and BBQ are instantly understandable shorthand to English speakers, why create an artificially less obvious code?

GRouPcoin has been GRP since its original creation. And is ancient so has first claim to the symbol.

BBQcoin seems like it probably was thinking BBQ too, else why not call is Barbecuecoin instead of BBQcoin?

The fact that some exchange or other butchered BBQcoin to BQC seems though to indicate that even if GRouPcoin had been named GRPcoin someone would still have butchered it...

yes roadtrains repo , i forked it , linux builds right out of the box

i pushed to my own fork the few changes necessary to build on win

compiled with mingw 46, boost_1_55_0 , openssl-1.0.2a , qr support enabled, miniupnpc enabled

tested on win 8 and win 7 vm, now that I have coins I can test further, and check rpc console

hope no one is upset but the logo ect was just like I found it in the tin, just looked like a coin that needed a wallet for windows 

thanks again very much for sending coins

When I finished compiling this the other night I was pretty tired,  just realized I did not push the few changes made to source to the proper repository I was working from so everyone can easily see what was 'corrected' to be able to build this windows-qt client. made a little mistake.....


EDIT ONE --I DELETED THE 2nd Repo TO AVOID CONFUSION

EDIT TWO == Suggestion, coding does require you to actually sleep from time to time or you can make a stupid mistake

There are so many repo's floating around somehow i think i pushed the group coin code to an i0 coin repository i cloned..........

No worries , no damage done,  new wallet + corrections + all fixed now

Big hugs to MarkM and mmpool  :o :o :o for allowing me to waste their time and also pointing out what I should have noticed myself  :'( :'( :'( :'(

Source used https://github.com/cinnamoncoin/groupcoin-1 (https://github.com/cinnamoncoin/groupcoin-1)

Minor revisions I made https://github.com/cinnamoncoin/groupcoin-1/commits/i0coin-0.8.x (https://github.com/cinnamoncoin/groupcoin-1/commits/i0coin-0.8.x)
 

I never ran into rsnel Roadkill however he did the heavy lifting appears commits are almost 2 years old !!!
Tested on win 8 , tested in win 7 also
In linux it built right out of the box.

The wallet I built is on my pc not with me at the time and connected right up to the network and download the blockchain.

Please let me know if the wallet works ok for you / or if there are any obvious issues and when I have time I may be able to look at them.

Please also understand that I get the impression this coin was started/run by markm.  I have other projects I am currently developing /researching.

I am not trying to 'take it over' in any way.  

Markm if you would like a logo replaced or checkpoint added (unless you prefer to do it yourself) post the logo here and when I have some time I will try to rebuild it. I know very little of the early history of this coin but difficulty was a couple hundred thousand when I built the wallet and is up to 4.5 million right now.
 


It can be merge mined with bitcoin and is at MMpool ..... http://mmpool.org/ (http://mmpool.org/) along with a total of 5 other coins !!

Title: Re: GRouPcoin
Post by: markm on June 30, 2015, 05:01:32 AM
I sent you two sends of 1000 GRP each. Partly following above precedent maybe but partly simply because when initially shipping the coins out of the wallets they are mined into 1000 is a small enough collection of 50 coin mining rewards that the client can build the transaction.

Players used to roleplaying games where there are so many copper coins to a silver coin, so many silvers to a gold, so many golds to a platinum and so on used to figure that logically GRouPcoin should be a thousand-devcoin-piece since it mints 1/1000 as many coins as DeVCoin does.

Miners might tend to argue though that such a convention ought to be adjusted for difficulty, with GRouPcoin less difficult than DeVCoin thus presumably less secure, it should be worth less than a thousand DeVCoins per coin.

Looking at http://galaxies.mygamesonline.org/ingroupcoins.html (Asset values expressed in GRouPcoins) it looks like folks have been losing faith in miners' ability to restrain themselves from throwing away the GRouPcoins for free or close to free; current latest values file shows them worth less than a DeVCoin each!

I wish that the gnuplot plots were working, it'd be nice if the DeVCoin folks would offer a DeVCoin bounty for figuring out what broke with those, basically the plot pages worked nicely when I was running gnuplot on Fedora but when I changed over my home systems to Ubuntu suddenly all the HTML pages of plots produced and uploaded to the webserver just look like blank pages now with the Firefox that comes with Ubuntu.

( Links to tables and plots are shown on the menu page http://galaxies.mygamesonline.org/digitalisassets.html )

Still, one can scroll down the http://galaxies.mygamesonline.org/ingroupcoins.html page to see that GRouPcoin was not valued so low in the past...

Last time bitpop offered to sell me some at the rates shown in the latest rates include-file (from historical archives of which the tables and plots are generated) I said I kind of had enough for now and he said well maybe he will just give them to me someday then. I anecdotally mentioned that conversation to some players (of Galactic Milieu (http://devtome.com/doku.php?id=galactic_milieu) of course) and pretty soon they all seem to have decided to just sit and wait for miners to give them away. :)

So thanks bitpop for at least giving them as bounties to someone deserving instead of just giving them to a rich old fart such as me. :)

Lol you waited me out. You guys should ask mmpool miners for some. I'm done mining now.

I don't think Mark created this coin?


Title: Re: GRouPcoin
Post by: markm on June 30, 2015, 12:02:38 PM
I did create it, as hired hand working for Unthinkingbit to help him create DeVCoin.

We made GRouPcoin first as a testbed to test various coding approaches toward what he wanted DeVCoin to do, then once we figured out how to code DeVCoin GRouPcoin was left as a simple 50 coins per block forever coin.

He would have been fine with just abandoning it but the gamers who had mined it to help us run the testing didn't want their characters in games to wake up without their GRouPcoins in their backpacks kind of thing so we just kept it running so the folks using it could keep on using it.

Gamers can be great for playtesting stuff but taking away their pile of sand after they have built their sandcastles with it just isn't kosher. :)

So technically it is just slightly older than DeVCoin, but is part of DeVCoin development so maybe should be thought of more as part of the DeVCoin project than as a rival coin that preceded DeVCoin.

(As I mentioned, gamers used to copper silver gold platinum etc at fixed exchange rates kind of hoped it would simply function as a 1000-DeVCoins denomination coin.)

Cinnamon, I am sending you two more sends of 1000 GRP each, do you think you could put your github repo at a less confusing URL, one that actually says GRouPcoin instead of I0Coin and without another URL embedded in the URL ?

Thanks very much for coins.
I will rename repository asap probably tonight : it will change the url so I will then edit the corrections here so no one gets a 'dead link'. Difficult to do properly without some of my hardware atm.  :D

As req I deleted the unnecessary duplicate repo on github & renamed my fork of the other Groupcoinmaster

I edited my posts in the thread here with updated url's since when you rename a repo those url's are no longer valid.

Cheers :-)

That's great work, thanks!

Would you be at all interested in having a look at the Geistgeld (XGG) client? I've been trying to get it running with my merge mining p2pool node for yonks, I eventually managed to get it compiled & running, but it sends my memory usage into overload & eventually clogs the system up. It's a shame not to use it......

Any ideas or suggestions would be very much appreciated - it's beaten me  :(


Title: Re: GRouPcoin
Post by: markm on July 02, 2015, 01:53:19 AM
GeistGeld only has the so called "dirty fix" of the RAM problem, not the full/clean fix.

That is still way better than no fix at all, of course.

The .git/config in the repo I have been using loks like that:

Code:
[core]
        repositoryformatversion = 0
        filemode = true
        bare = false
        logallrefupdates = true
[remote "origin"]
        url = https://github.com/rsnel/geistgeld.git
        fetch = +refs/heads/*:refs/remotes/origin/*
[branch "geistgeld_dirty_fix"]
        remote = origin
        merge = refs/heads/geistgeld_dirty_fix

Which I think means I am using a specific branch or tag, one to do with the dirty fix, rather than using the bare main top of the repo you'd get if you just used the clone URL github shows you as the URL to clone the repo.

The main problem I have with p2pool that isc specific to GeistGeld is that until I get GeistGeld's difficulty high enough p2pool makes so many requests to it so fast that the operating system runs out of connection handles, then p2pool cannot open connections to anything.

So I would have to solo mine it at higher and higher hash rates until I got the difficulty high enough that p2pool would not choke on it.

This would be solved of course if umpteen people all merged it. It happened to me when no-one else or no-one else with much hash rate was mining it and my pool or main miners went down or off the net or whatever.

Geistgeld's difficulty would plummet fast as it is very adaptive difficulty-adjustment. So very son it wo0juld be at tiny difficulty, nice to CPU-mine but choking to a terahash of mining power on the p2pool.
(My problem with p2pool that is not specific to geistgeld is my Neptune would not get more than one terahash pointed at p2pool though it could get 2 or even 3.4 on mmpool).

Thank you , after almost screwing this job of , (well not the wallet but pushing the code to the correct repository !!) 

I think I will revisit Geist at a later time.  (maybe)

Actually the more I think about it the more I like Groupcoin ,

No 21 million cap, award never cuts , it pays out 50 a block , permanently !!

Also has good security with difficulty well over 15 million and 10 minute blocks

This codebase 8.x supports level db so lot's of room for expansion of the network..................................

 ;) ;) ;)


A coin that pays out forever is certainly more in line with the 'politics' of the world !!!

Hell no one can say it is a pyramid scheme since you can jump in and mine anytime and get the same rewards





That's great work, thanks!

Yup, that's the same as mine, so at least I'm using the right one.

Exactly what I'm experiencing too.

This would be solved of course if umpteen people all merged it.

Maybe a synchronized mining start would solve this?  :D It never occurred to me to try cpu mining it actually.........interesting.

Ok then lets move GeistGeld discussion to GeistGeld's thread then...

-MarkM-


Title: Re: [GRP] GRouPcoin
Post by: markm on August 07, 2015, 11:58:30 AM
As you might or might not already be aware, General Holding Corp (http://devtome.com/doku.php?id=general_holding_corp) administers the interface between the Galactic Milieu (http://devtome.com/doku.php?id=galactic_milieu) and the underlying bandwidth, hosting, software development and so on that the game runs on.

A large part of the Corp's income is the fee per square mile that Freeciv (http://devtome.com/doku.php?id=freeciv) scale civilisations are charged for the privilege of running a civilisation.

In casting about for some way to rationalise this "hosting etc" cost in game terms, the idea of having it be a cost incurred by the ruling political party, aka the government, rather than the civilisation being ruled, was somehow hit upon.

The idea here is that the accrued backlog of fees incurred by a nation that lies idle for many game-turns would cripple the nation if it was an expense incurred by the nation itself rather than by those who wouldst fain govern that nation.

Doing it this way means that the nation can continue to stumble along itself thanks to the "artificial intelligence" provided by the Freeciv software, without any worries about paying the fee.

Meanwhile though the task of getting one's political party (such as the Royalist Party, the Despotism Party, the Republican Party, the Democratic Party, the Fundamentalism Party or even, if such a thing exists, the Anarchism Party) into power in that nation would become more and more daunting, thanks to the continued amassing of these fees plus the interest charged on outstanding fees.

So the upshot is that ultimately the hosting fees for hosting the Freeciv based worlds are being charged to groups, specifically the type of group that is known as a Party, as in a Political Party.

With this in mind, it is proposed that we tie these fees to GRouPcoin.

Initially the fees will continue to be computed in the same way they always have been, which is to say, in terms of "units of Deuterium", as listed at

http://galaxies.mygamesonline.org/deuterium.html

So far it has been customary to allow these fees to be paid in any of the listed currencies, since of course Deuterium itself is a resource that exists in galaxies far far away and thus is not actually available, at least not in significant quantities as a commodity resource, among the Freeciv worlds.

(In fact technically that Deuterium pricelist page does not refer to the isotope itself wherever it may be found but, rather, to delivered units of it delivered to depots located among a certain set of Galaxies Far Far Away.)

However the plan is to first move to insisting that the hosting fee be paid in GRouPcoin, and then possibly, later, to computing it in the first place in terms of GRouPcoin instead of in terms of Deuterium.

Basically we convert Freeciv scale (terrain tiles 100 miles by 100 miles in size or thereabouts) into OpenSimulator scale ("Regions" 256x256 metres) by generously allowing a square mile to be represented by a four by four block of "Regions", thus 16 "Regions" to the square mile, which is where the factor of 16 comes from that leads to the hosting fee being 1.6 units of Deuterium per "square mile".

Political Parties thus pay thousands of thousands of units of Deuterium per real life month to control a large civilisation.

This could thus have a decent impact upon the perceived value, thus the price per coin, of GRouPcoin.

It should be noted, for Parties who might consider taking control of large civilisations, that of course the more shares one owns of General Holding Corp the less of a burden these fees might appear. :)

One little detail remains to be looked into though, which is whether there even exist enough liquid GRouPcoins to enable them to work for paying fees? Are there enough in circulation that it is practical for folks to be paying many millions of units of Deuterium worth of them every month? What will General Holding Corp need to do with them in order to ensure the coins taken in get back into circulation to be used again the next month to pay the recurring fees again? Hmm... Maybe in light of that thought it is a good thing that GRouPcoins continue to be minted at a constant rate?

This is good news!  :) I've been mining these since I first started on the scene, nice to see GRP finally doing some moves. With regard to weather there are enough GRP in circulation, maybe now is the time to push for a few exchanges? Maybe this would ensure there are adequate amounts available.....?

The daemon runs great, very low resource usage. It would be nice if the QT wallet had it's own insignia instead of the i0coin logo - but I'm not sure I've seen a GRouPcoin logo anywhere.....?

I have applied the BIP-30 patch to groupcoin, latest source code is at

https://sourceforge.net/projects/galacticmilieu/files/GRouPcoin/

It seems we never did get around to applying the merged mining (as aux chain) patches to groupcoin-qt so currently wxWidgets is the only GUI available, it is right in there with the groupcoind in the groupcoin-09-Mar-2012.tgz archive.

-MarkM-


is there an official ann for this coin?


Title: Re: [GRP] GRouPcoin
Post by: markm on December 08, 2016, 10:43:41 PM
I think the ANN section of these forums did not exist way back when.

Also I believe it was probably announced in a DeVCoin development thread as it was created during the initial phase of DeVCoin development when we were looking for ways to divide minting among groups of people. Once we figured out how, that feature was moved into DeVCoin and GRouPcoin became just a nice simple 50 coins per block forever merged mined SHA256 coin cmerged mined alongside BiTCoin and other such coins.

But I do see this in the announcement section: https://bitcointalk.org/index.php?topic=67991.0
