Groestlcoin (GRS) is a fast and secure cryptocurrency with almost no fees for transferring coins. GRS was the first cryptocurrency to implement Segregated Witness (SegWit) and perform the first Lightning Network transaction on its mainnet network.
Launched in Mar 2014, Groestlcoin utilizes two rounds of Grøstl-512 for its mining algorithm and has a team of over 20 developers working on the coins code.
The Groestlcoin developers have committed to updating the projects core code once every three months.
