Groestlcoin is a cryptocurrency which has a ticker GRS and appeared in 2014 as a result of the fork of Bitcoin. The creators of the project are convinced that decentralization is a key condition for the success of any coin, and it should be supported by as many private miners as possible, rather than large pools or mining companies.



To achieve the stated position, Groestlcoin uses a mixed consensus method – PoW and PoS. Proof-of-Work works using the Groestl algorithm, which effectively counteracts ASIC mining. In turn, Proof-of-Stake can be used for cryptocurrency mining – simply by storing funds on account, users can get about 2% per year.

The total projected number of coins, with 105 million reward for the first extracted block equal to 512 tokens, and after every 10000 blocks, this number is reduced by 6%. Intra-network transfers are characterized by high speed and the absence of any commission.


It was developed at the Technical University of Denmark and has many differences from the widely used Secure Hash Algorithm 1. Groestl prevents ASIC devices from working, but it also prohibits large pools, which usually receive a huge share of mining profits thanks to their hashrate. Thus, Groestlcoin welcomes individuals or pools of small size.


To start mining, users need to download special software, as well as a wallet. Easyminers software adapts itself to the capabilities of a particular computer, and users can get the currency both through the video card and through the processor. There is no need to understand complex settings, make changes to bat files or search for pools to connect. It makes mining easy even for beginners.
