QuarkCoin often shortened to QRK is based on Sifcoin which in itself is similar to the famous bitcoin and is also a crypto currency in its own right. Little is known about who created QuarkCoin but one of the creators goes by the name maxguevara on www.quark.freeforums.net. The main idea behind QuarkCoin is to increase security and be done quickly. To achienve this goal the creators modified a few aspects of the sifcoin protocol these are:

Shorter block time creation

30 Seconds block creation 2048 QRK per block (halving every 60480 blocks ~ 3 weeks)

Other changed aspects

Block rewards will not drop beloow 1 QRK Total of 247 million QRK will be mined in ~ 6 months, after that ~ 1 million QRK p.a. (~ 0.5% p.a inflation) Difficulty will re-target every 20 blocks (maximum 10% up or 50% down)

New key format

Wallet public keys now start with the letter q instead of the number 1 which is how Bitcoin wallets are formatted.

Qrkcoin can be mined on CPU or GPU however a higher hash-rate can be achieved through CPU mining, and this is done on port 6010, this coin can be mined on many pools one being www.coinmine.pl, this involves downloading an .exe file with other files and creating your own start.cmd script.

How to create a start.cmd script

Creating this script will start the CPU miner and send the results to your pool via your worker, first you will need to determine how many physical cores your computer has and then the script should go as follows:

minerd64_sse4.exe -a quark -o stratum+tcp://qrk.coinmine.pl:6010 -u username.workername -p password

sse = the number of cores in this case the number of physical cores is 4, if you have HT it will use the other cores automatically, this is all put into a .txt file once completed it should then be saved with the file extension .cmd .


QrkCoin can be traded on http://www.vircurex.com for bitcoin and https://www.cryptsy.com .
