GNT or Golem Network Token is needed to pay for computations on the network and is the currency that drives our marketplace. As a Requestor, you set a bid for an amount of GNT you are willing to pay to have your task completed. As a Provider, you earn GNT by computing tasks for Requestors. You can set your minimum and maximum price thresholds in your settings.
Golem uses the Ethereum blockchain to facilitate fast and secure payments between Requestors and Providers. ETH is the native currency of Ethereum and is used to pay for transaction fees on the network. Only a small amount is needed to complete a transaction. All Applications built on the Ethereum blockchain pay for transactions using ETH.
