[ANN] New Crypto Currency - GameCoin (GME)

[JimmyFL]

gamecoin and feathercoin blockchains are identical up to block 6634. Nice pre-mine there waiting for feathercoin early adopters.

Code:

gamecoind importprivkey `feathercoind exportprivkey <ftcaddress>`

Are you sure? I'm getting

{"code":-5,"message":"Invalid private key"}

And the same error when I try to import the GME private key to FTC.

And btw it's dumpprivkey and not exportprivkey

You're right. The privkey has to be converted for the gamecoin network and the checksum recalculated. Here is the python code to do it:

Code:

#!/usr/bin/env python

from base58 import b58encode,b58decode
import struct

import sys
import hashlib

wif = sys.argv[1]

raw = b58decode(wif, None)

net,key,x,checksum = struct.unpack('>B32sB4s', raw)
check = hashlib.sha256(hashlib.sha256(raw[:34]).digest()).digest()[:4]

try:
    assert(check == checksum)
    assert(net == 142)
    net = 166
    gamecoin = struct.pack('>B32sB', net, key, x)
    gamecoin_checksum = hashlib.sha256(hashlib.sha256(gamecoin).digest()).digest()[:4]
    print b58encode(gamecoin+gamecoin_checksum)

except AssertionError:
    print "Invalid feathercoin private key"

Use with base58.py from https://github.com/imsaguy/python-base58/blob/master/base58.py

Code:

I'm a noob in cryptocurrencies, are you telling that this new coin is a total crap and if someone mined a lot of FTC can convert them 1-1 with new gamecoins?

Only if you was solo mining before the block 6xxx

Yes, 1.3 million of them, assuming it works. Anyone tried it? I don't have any old feathercoins to test it with.

I'm on windows 7, do I need any software to try? I mined old feathercoins and I still have my old empty wallet.

Key import is working. Would do mind write a script to doing the the other way? dump in game => import in feather

Yeah... I will do it my self.My python knowledge is just basic, but the script appears to be pretty simple.

selling 2k - no idea what price to charge so just make me a sensible offer by pm and it's yours.

[jk1985]

Selling 7500 GMC.. PM your offers!

My python knowledge is awful, let us know if you can write a scrypt

Just swap around 142 and 166. These are the feathercoin and gamecoin identifiers respectively.

There is no point in doing this though. You will not gain anything going the other way.

Why is this 'zip wallet the only one that gives me a malware warning before I download it.... hmmmm

[blastbob]

chrome gives warnings if the files is "new" in their list. Windows 8 gives warning on unsigned code etc..

Scan the files with your own antvirus, and upload files to virustotal. Then run everything in sandboxed enviroment. Like Oracle Virtualbox

Hey guys. Is there already a going rate for Gamecoins? GMC/BTC?

[syn999]

Hey guys. Is there already a going rate for Gamecoins? GMC/BTC?

50k for like 5-10ltc
i have seen something like that

Hey guys. Is there already a going rate for Gamecoins? GMC/BTC?

Yes there is it's 1,000,000 GMC/0.0 BTC

I ran an analysis on the double spending caused by feathercoin blocks. This is my result.

Top address with gamecoins from feathercoin is this one:

6mQ5euk9mGQCx9GEkk5UX9q5q5Q4gUypf1 134990.00000000
  txid: 1e868f1939e951d4294ba050ff59ffebf5844a3bf4c10cf64632d0e5efce1e95 vout: 0 value: 10000.00000000 SPENT IN BLOCK 6678
  txid: d9ed96d0b513ea053665ab413a418a80142b14bf12a881529b58c05a49ba8589 vout: 1 value: 124990.00000000 SPENT IN BLOCK 18582

124990 feathercoin was sent to this address in block 6634... interesting, huh?

The rest of the addresses:

Note that the reason they are getting spent in gamecoin is not likely due to people intentionally claiming them, but rather because tx are crossing over from feathercoin and getting into gamecoin blocks. It should only be possible for these coins to be moved once by accident like this. Your gamecoin balance from importing feathercoin keys may not be identical to your feathercoin balance at block 6634 due to these cross-tx, and anyone who received feathercoins today might have got some gamecoins by accident too.

Just read the frirst or second page, someone lost 3M GMC couple hrs after announced.

its not going to worth anyting

[evershawn]

anyone want to trade some GME for any other alt coin? PM me or reply with an offer.

[Andry]

ill take donations GYquDha9yZbKan7phfhGVSvJ2eKxkJ2P9e my wallet looks so empty

The p2P is also down?

[justover]

I've added a new p2pool.

Here are the parameters:

cgminer --scrypt -o 88.161.131.83:8112 -u yourGMCaddress -p .

statistics available here: http://88.161.131.83:8112

2% fee.

----
This one is up, and fully reliable.

This one is working well for me.  I have alot of rejects though.. 

This p2pool works quite well for me too...
