Whether it is possible to attribute to John Nash who was on leading edge of mathematical and economic thought with the idea of "ideal money" to attribute a merit in forming of the electronic money known as "cryptocurrencies"?

In one of the lectures he claimed:
Special goods, or means which we call money have a long and interesting story. And as we so strongly depend on its use, and we are under the influence of desire to have their bigger quantity and not to lose what we already have we are inclined to irrational thinking into their account. Therefore we can lose sight of technology aspects of their use and an opportunity to use them is more or less effective.


Nash described the concept of ideal money as certain unit of the standard of measurements, that is, something like watts, hours or degrees.

He claimed that ideal money has to provide an acceptable solution of paradox of Triffin (a key contradiction of the Bretton Woods system):
To provide the central banks of other countries with necessary quantity of dollars for forming of national currency reserves, it is necessary that in the USA deficit of the balance of payments was constantly observed. But deficit of the balance of payments undermines confidence to dollar and reduces its value as a reserve asset.
