Required Methods

fn is_ready(group_id: Self::GroupId) -> bool

Check if the group is ready to be rewarded. Most of the cases it means that the group has stake that should be rewarded.

fn reward_group( group_id: Self::GroupId, reward: Self::Balance ) -> Result<Self::Balance, DispatchError>

Reward a group distributing the reward amount proportionally to all associated accounts. This method is called by distribution method only when the group is considered ready, check GroupRewards::is_ready(). The method returns the minted reward. Depending on the implementation it may be less than requested.

fn group_stake(group_id: Self::GroupId) -> Self::Balance

Retrieve the total staked amount.
