The main idea of creating Groestlcoin (CRYPTO:GRS) was to establish an electronic payment model that was purely based on mathematical proof. This is a system that is independent of influence from centralized authorities, a currency transferable electronically, and instantly at a very small fee.
Groestlcoins are created by miners on its network as a reward for confirming transactions. The founder pointed that only 105 million Groestlcoins (GRS) will ever exist when all the coins are mined.
