Module distribution 

Storage fee distribution into epochs

Data is stored in Platform “forever” currently, which is 50 eras (50 years by default). To incentivise masternodes to continue store and serve this data, payments are distributed for entire period split into epochs. Every epoch, new aggregated storage fees are distributed among epochs and masternodes receive payouts for previous epoch.
