Banker Bots as a pure unit of account

Left to its own devices the flow constraints are simply a tool, like the Feynman diagram or the Wythoff move, that computed the one period move to match a two period projection.  A standard Ito tool, always adjusting the grid size so Ito works.

So, as a pure unit of account, banker bot just accepts withdrawals and deposits, without regard to their source.  It will maintain the highest order polynomial that captures the probability distribution within a precision, which is automatically set.  So, a pure banker, the bot will set rates, and make the curve as long as possible so no one goes broke and always has time to pay off their losses.  Treat the user accounts as savings and loans or yesterdays and tomorrows, whatever.  Unrealistic, certainly, so banker bot requires due diligence of its members.

But, require each member to have a certified SmartCard, then pure money works.  Just limit the cards to a small range out of band. The internal bot on the card will always provide the no arbitrage price within that range.
