Our current system is based on ERC 20, which is used for the ICO, we will later migrate to our own POS based blockchain with master nodes and our specifications. The reason for doing so is quite simple, the current market we are trying to address is dominated by players such as Google, Baidu, AWS, so by relying on external cloud services - we are leaving ourselves open to being shut down at any time in the future by current monopolies.  Gath3r is a web miner, which uses the excess power of both the CPU and GPU to mine cryptocurrency with user's explicit consent. Our smart miner switches algorithms based on profitability, we also have the loyalty program: Webmasters can opt to share a percent revenue with end users which would be paid out in GTH. Webmaster can choose to receive earnings in BTC, GTH, or bank transfer, where available.  To get a more in-depth read about Gath3r check out our review on ICOpools here: https://icopools.io/en/ico-details/gath3r
