 Payment should be added to the transaction in ETH and the amount is `firstReward * miners.length + rewardRate * periods * miners.length`.
 The reward rate must be greater than or equal to the minimum reward for each miner in the list. The first period's reward is not refundable, and can be zero.

+Computation of a policy reward happens every time `mint()` is called by the `updateReward(address, uint16)` method.
 In order to take the reward, the miner needs to call method `withdraw()` of the contract `PolicyManager`.
 The miner can set a minimum reward rate for a policy. For that, the miner should call the `setMinRewardRate(uint256)` method.

 A more convenient way is to use a proxy contract with an interface where each method redirects to the *target* contract.
 This option is advantageous because the client uses one address most of the time but also has its own methods.
