You will learn how to activate and start delegated harvesting in NanoWallet. Additionally, you will learn two ways for harvesting. These are delegated harvesting on a remote server provided by somebody else, or learning how to use delegated harvesting by running a local NIS yourself. To activate and start delegated harvesting in NanoWallet you need a XEM Account with at least a 10'000 XEM vested balance. To check how long it takes for you to get a vested balance of 10'000 XEM, you can use this harvesting calculator.
~Activation Before you can start delegated harvesting, you need to activate it. Consider this to be the same thing as registering on the blockchain that you want to harvest. To do so go to "Services - Manage delegated account" and activate it from the left panel by entering your password and clicking "Send". Activation takes ~6 hours and will cost you 6 XEM in fees. Activation only needs to be done one time per account.
