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...

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

Sadly it doesnt help with cygwin:

Code:

Frank@Trinity ~/groupcoin/src
$ make -f makefile.unix.new groupcoind                                          
g++ -I /usr/include/db4.8/ -w -c -O2 -Wno-invalid-offsetof -Wformat -g -D__WXDEBUG__ -DNOPCH -DFOURWAYSSE2 -DUSE_SSL -I/home/Frank/groupcoin/src -I/home/Frank/groupcoin/src/obj -o obj/nogui/main.o main.cpp

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.

Btc would never start with 2

Interesting

Thanks for the hint with VanityGen.

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

can anybody explain how to get a "2"-prefix for a groupcoin address? All I could get ouf fron VanityGen are the prefixes "1", "N", "n", "M", "m".

thanks

I'd like to know how to create an address as well, please.

I found out how to get your own GRouPcoin address via VanityGen:

vanitygen.exe -X 3 2

Vanitygen spit out: 2mar3rNLbP9M4oFdLXPNaL4jw2kbDQyWpE

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

Have a nice mining!

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?

[TheSwede75]

Groupcoin wallet?

[SebastianJu]

Groupcoin wallet?

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.

dont use *coind on a SD card (ie RPi) as SD cards start to fail fast...
also groupcoind uses somuch RAM, you couldnt run it

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?

OpenTransactions would help, check them out in the IRC channel and ask if someones want to buy them (if you dont want to use OpenTransactions)

Thanks for the tip. Sounds interesting.

[chick750]

[SebastianJu]

Please can anyone post here link for linux/windows groucoin wallet?

I believe there is none. And i wasnt able to install the linux one yet since its not my best known OS.

Or at least some "sudo" thing for ubuntu / xubuntu
