【User Flow】

① User register as a "prosumer" (Both of producer and consumer) ② Measured values of the smart-meter are measured at the end of every month by instruction of smart-contract. (measured smart-meter are both that from production and from consumption) ③ Measured values from production and measured value from consumption are compared. ④ Transfer
・If the measured value from production is greater than measured value from consumption, the smart-contract transfer payment tokens into the prosumer's wallet. ・If the measured value from consumption is greater than measured value from production, the prosumer transfer payment tokens into the smart-contract. ⑤ Invoices of monthly result are sent to each prosumers. (at the end of every month)
