Can you expand on the nash concept of ideal money. I am unfamiliar with his theory.
The wikipedia page is not helpful.
https://en.wikipedia.org/wiki/Ideal_moneyIt says only
"In John Nash’s lecture he mentioned "Good money’,is money that is expected to maintain its value over time. ‘Bad money’ is expected to lose value over time, as under conditions of inflation"
and
"John Nash mentioned in his lecture that Euro might become an ideal money in the future, because Euro is used in a large range of places and has a good stability"
Stating that ideal money is money that maintains value over time forces you to define "value" and address why money that maintains "value" is superior to money that increases or declines over time.
http://sites.stat.psu.edu/~babu/nash/money.pdfasymptotically ideal is what I believe he refers to as something like bitcoin. Note we will never have perfect money, where inflation is tied to a real economic indicator that is easily auditable and one that cant be tampered with, but bitcoins falls under the curve closer to infinity than inflation targetted currencies today.
Notable quote which would make sense to most here :
"money should have the function of a standard of measurement and thus that it should become comparable to the watt"
Btw i believe nash was satoshi.
Interesting read thanks.
The critical postulates from the the Nash lecture above are the following:
1) Money should ideally have the function of a standard of measurement and this should ideally be comparable to the watt or the hour or a degree of temperature.
2) Ideal money should be free of "inflationary decadence" and the ideal rate of inflation over the long term is a zero rate of inflation
3) Currencies are in competition with each other and over time and individuals are increasingly able to "vote with their feet" leaving inflationary currencies for those that are more stable.
4) Over time competitive pressure will result in natural selection and lead us ever closer to ideal money. This process is referred to as asymptotically ideal money
Unfortunately, these ideas are essentially left as unsupported posits in the lecture linked above with little in the way of supporting framework.
I would have liked to read the actual publication referenced in the lecture to see if Nash has developed deeper justifications supporting these ideas. The referenced paper in the lecture does not seem to be be available online. Its abstract is here.

A) Ideal money has both zero inflation and zero deflation over time. Only a currency that neither gained or lost purchasing power would meet the criteria of a standard of measurement comparable to a watt, the hour, or a degree of temperature. Deflationary currencies would fail this test just as inflationary currencies do.
B) Money that is not ideal, but better then the existing system would be expected to thrive and supplant that system until a superior solution even closer to the ideal is discovered
C) For Bitcoin to meet the criteria of a true ideal currency the the human population would need to stabilize at a fixed number and technological progress would have to plateau or the bitcoin protocol would need to be modified to modify the supply of coins in existence in response to technological improvements and or population changes.
