In our Green Chain platform network, peers deal only with data and processing needed by their applications, becoming responsible for them.  This makes the network very lean, with close to zero redundancy. Since  there are not excessive resource demands, there is no need for mining, nor for any kind of token whatsoever.  Whenever an application needs to deal with actual values, real-world currencies, our chains can be applied to the process – and dealt with.  No mediator tokens required.
