Beckstrom’s law says the value of the network is not the square of the number of nodes, it is the difference between the value of the transactions and the costs.

as a formula:

V = B – C’ – SI – L

where

V is Value

B is Benefit

C’ is the remaining Costs

SI is the Security Investment and

L is the Losses

The formula makes sense. The trick is sensibly quantifying the variables.
