The app uses GPS to tell which impact zone you are in. Each impact zone will have it's own Emrals address and be funded by donations through subscriptions and masternodes. Using the app, the person cleaning up will then take a picture of the trash they are about to cleanup and then a picture of it being thrown out. They will then get the reward of x amount of coins depending on how much funding the neighborhood has. Additionally, on the eCan, when an item has a barcode scan or is identified either by Ai or the human, they will get EMRALS depending on the value of the item being thrown out.
Let's focus on the bolded part first. Does it means if there is no donation to certain area, there will be no reward given for trash-picking? Which means, how active and rewarded someone for cleaning is depends on how many people resides on the area who adapt your coin?
The areas will also be funded by the system's masternodes and initial funding. Each location will start out with 10,000 coins and Emrals will setup masternodes that are dedicated to the areas as well.
Will it be safe to assume that every area will have an equal reward rate for each unit of trash collected? Like, in an populated area and in a less populatef area? If they will be different, what factors will influence these rates?
To start out with yes. Over time we may want to adjust the rewards based on how the system is being used, sort of like a mining difficulty.
