All the modification are disabled by default and the behavior for all tribes will remain untouched unless they activate one of the new options.

## Disable downvoting
This new parameter can be found in https://scot-api.steem-engine.com/config.
Default setting is `false`. When set to `true`, downvotes will be completely ignored on the tribe and downvoting a post/comment will not reduce the pending payout.

## Separate comment pool
It is now possible to have a seperate comment pool
`enable_comment_reward_pool` in https://scot-api.steem-engine.com/info activates the comment pool. Default setting is `false`.

When set to `true`:
* `pob_comment_pool_percentage` of the pob_reward share is added to the `comment_reward_pool`
* author, curation and beneficiaries of all comments are paid from the `comment_reward_pool`
* author, curation and beneficiaries of all main posts are paid from the `reward_pool`

It is also possible to disable rewards for comments by setting  `pob_comment_pool_percentage=0` and `enable_comment_reward_pool=True`.  `comment_reward_pool` will then remain 0 and the the rewards for curation and authors will be always zero for comments.

When `pob_comment_pool_percentage` is set for example to 10%, 10% of the token which were before added to `reward_pool` are now moved to the `comment_reward_pool`. comment authors and voters are now paid from this separate pool.

Each tribe has now a field `comment_pending_rshares` which shows the rshares sum for all pending votes on comments. When a tribe has enabled `enable_comment_reward_pool`, the token reward is calculated by:

```
if post["main_post"]:
    pending_token = int(weight_rshares / (pending_rshares - comment_pending_rshares) * reward_pool)
else:
    pending_token = int(weight_rshares / comment_pending_rshares * comment_reward_pool
```
where `weight_rshares ` is the weighted rshares sum of the post/comment itself, `pending_rshares` is the sum of all weighted rshares from all posts/comments and `comment_pending_rshares` is the sum of all weighted rshares from comments only. `reward_pool` is the normal reward pool and `comment_reward_pool` is the separate comment reward pool.

## Use the ratio between staked and circulating token for modifying the reward pool
This new parameter `use_staking_circulating_quotent` can be found in https://scot-api.steem-engine.com/config.
Default setting is `false`.

When set to `true` the reward pool is increased by:
```
rewards_token = totalStaked / circulatingSupply * rewards_token
```
`rewards_token` is added every `rewards_token_every_n_block` to the reward pools.

By using this new option, a tribe can increase the token reward by staking more token or decrease it by issuing or unstake tokens.
When for example a tribe adds 1 token every block to the pool, 28800 token are then added per day. Depending on the number of posts, a few user may receive a lot token in the early stage.

This can be prevented by `use_staking_circulating_quotent`.
When the tribe in the example issues 100k token to a curation account and stake only 1k of them, only 288 token will be added to the pool. The tribe owner can then stake more when more user use the tribe.

After a while when more token were issued, the user itself can determine how big the reward will be. When they sell all earnings and nobody stakes them, the reward will stay low. When more accounts begin to stake, the reward size will increase.
