In order to earn FTM, a FTM holder has two options:
Running a validator node, or
Delegating to a validator node
Read a full guide for delegating here - our validator id is 15
Validator nodes actively participate in the consensus of the network to validate transactions. A validator must, at all times, maintain a minimum stake of 3,175,000 FTM (0.1% of the total supply).
Regular users can delegate their holdings to a validator node. The delegating user will have their tokens locked but does not have to run dedicated staking software. The minimum stake in this case is only 1 FTM.
Validators will earn fees through three mechanisms: Returns (Validator) = block rewards + transaction fees + delegated fees
Delegators will earn fees through two mechanisms: Returns (Delegator) = block rewards + transaction fees - delegated fees
The total reward given to a delegator is represented by this formula:
Daily Delegator Reward = Daily Validator Reward * (0.7 * tokens delegated / validator weight)
