Bitcoin as an Ideal Basis For Nash’s Ideal Money

Over the last few years I’ve been in dialogue with a math professor that has been kind enough to hear me express the importance I see in John Nash’s works Ideal Money. More recently he came to me with a question and if I recall it correctly the question was, “How can we have the same (secure) technology as bitcoin but without the energy waste?”

When I first heard this question I jumped at it too hard and gave what would have probably been received by the professor as an aggressive and not very helpful or coherent response.
