What is the difference between staking and farming?
STAKING: To stake your $KIND you don't need anything else than $KIND
FARMING: To farm you need to provides liquidity to one of the pools on the farming page and then stake your LP tokens.
Both have their own advantages and disadvantages. Which one to choose is up to your strategy.
How do I farm?
First, you have to provide liquidity to one of the pools which you can find on the "Farm" page.
After providing liquidity and receiving your LP tokens then select the pool you joined from the "Farm" page, approve the contract and then click on the little "+" sign, choose the amount you want to stake and confirm.
When you vote a project on Vote page, the $KIND you used to vote will be change to AllocPoint.
It's like a share holder for the project. More AllocPoint the more reward for the project.
How do Votes work?
You can vote one of the contracts at the Vote page. You can vote one, three, ten, or however you want. 50% $KIND from Vote will be burned, 25% will be given random to lucky voter, and the 25% will be directed monthly to chosen social organizations.
For example you want to vote up using 4 $KIND on one contract, then the project that you voted will add 4 AllocPoint. It means your $KIND will reduced 4, and then 2 $KIND will be burned, 1 $KIND will be given to lucky voter and 1 $KIND will be directed to chosen social organizations.
