/**
* This defines how rewards are paid to users.
*
* Explanation:
*
* Proportional Payout System
* When running a pool on fixed mode, each block will be paid
* out as defined in `reward`. If you wish to pass transaction
* fees inside discovered blocks on to user, set this to `block`.
* This is really helpful for altcoins with dynamic block values!
*
* PPS Payout System
* If set to `fixed`, all PPS values are based on the `reward` setting.
* If you set it to `block` you will calculate the current round based
* on the previous block value. The idea is to pass the block of the
* last round on to the users. If no previous block is found, PPS value
* will fall back to the fixed value set in `reward`. Ensure you don't
* overpay users in the first round!
*
* Available options:
* reward_type:
* fixed : Fixed value according to `reward` setting
* block : Dynamic value based on block amount
* reward:
* float value : Any value of your choice but should reflect base block values
*
* Default:
* fixed
* reward_type = `fixed`
* reward = 50
*
