Reward

The reward module supports settlement to validators.

Concepts #

RewardDistributeAccount stakes XPLA and a portion of all delegation rewards accrued in RewardDistributeAccount are moved to the reward module account and devoted to settlement funds, which help validators to settle down on the XPLA Chain.

Transitions #

Begin-Block #

Each abci begin block call, the reward module claims all delegation rewards of RewardDistributeAccount. It claims every block, and this claimed reward is distributed to the reward module account, community pool, and reserve account. The ratio among recipients follows the parameters. The amount collected in the reward module account is divided by the number of expected blocks per year, and 1 block reward is sent to the fee pool. Finally, the rewards in the fee pool is distributed to all the validators in the active set and their delegators.

Parameters #

The subspace for the reward module is reward.

// Params defines the set of params for the reward module.
