Message fee structure

[neekolas]

Messaging fees need to be calculated in some unit of compute that fairly maps to the hard cost of sending a message on the offchain network.

We need an algorithm that can take a message and calculate the cost to store in abstract units.

We then need to estimate the price of those abstract units in dollars with today's network and define what levers are available to adjust the dollar price as our costs change and the network scales.

Some ideas and questions

• Is the model entirely variable, based on storage-size, or is there a component that is fixed per message?
• What other inputs might be useful in calculating the cost?
• How can we get a reliable estimate of the capacity of each node in terms of these abstract units? How does pricing change as the capacity and cost of an average node changes? Do we change the number of units for each message or the price per unit?
