`payout`

— total amount of reward for the post.`reward_weight`

— a weight of reward for a post.`funds`

— total number of tokens in the reward pool.`sharesfn`

— a share of tokens that allocated in the rewards pool to be used for reward for the post (this parameter depends on a weight of the post).`rsharesfn`

— number of tokens that allocated in the rewards pool to be be spent on reward for all posts (parameter depends on total weight of all posts).
