describe how you would want it to work

PoW $ for interactions, so if noisome oil rigs want to pump a well dry, then the cost may be set & reset at a sliding fee—approximate to an proportionate derrick—this would also work for others whom feel the same for Ars Truly 😉😎 Pun intended 😏🤓

so you set a cost per user? or global?

per thread?
