Locking your tokens has two purposes: You must lock tokens to allow you to vote for delegates. Whatever quantity of tokens you lock allows you to apply the weight of those tokens to your voting power when voting for delegates. The more tokens you lock the more your votes are worth. If you are in a fortunate enough position to be in possession of 187500 GNY tokens then you have the option to lock those up to signify your wish to become a GNY blockchain delegate and node operator. To lock tokens, you begin by clicking the user profile image button in top right of the “Home / Welcome” screen. On the next screen click on the button labeled “Lock status”. On the next screen, and within the field labeled “Unlock Height”, you should enter the block height you wish for the tokens to lock until. Please note: You are required to lock to a block height that is at a minimum 10 blocks higher than the current block height. Be advised that locking to a very high block height will mean that your tokens cannot be unlocked until that block height is reached, and as such your tokens will not be available for transfer until that height is reached. In the second field labeled “Amount”, please enter the amount of tokens you wish to lock. Then click the “Lock” button to complete the token lock. Please note: Account holders who have activated a second passphrase will be prompted to enter it before they are allowed to click “Lock”. You can return to lock additional tokens or unlock your tokens at any time in the future. In these situations the button that was initially labeled “Lock status” will now be labeled “Change Lock Status”, and clicking it will reveal a screen with “Increase Lock Amount” and “Unlock” button options. The blockchain fee to lock tokens is 0.1 GNY. There is no blockchain fee applicable when you unlock tokens.
