TRST Valuation
The motive of TRST is to create transparency and accountability. The actual means of valuation is not done by the BURST network; people can choose how they would like to value it, provided all the information regarding its transaction history. One can have various tools that would "check" and "verify" the real value of those tokens. That is up to the market to decide.
For example, you can have a system that undervalues an excessively long chain of transfers and undervalues older TRST tokens. It is not necessary for the BURST network itself to implement that formula/system because it can be done without using the computational resources of the BURST network (market determines the value based on agreed-upon key indicators)
