Well... The AI ive described would be very very slow. But when you think in terms of macroscopic time, like time relative to planets forming and stars being born and dying it would be very fast. lol
The same experiment could be done with a faster AI brain, taking the cryptocurrency out of the equation or letting the AI neurons talk to each other directly and unencrypted. But then someone could just take out the AI portion of the code and have just a plain wallet. The only reason I think it needs a cryptocurrency backing is its a great way to reward processing power.
What I'm talking about is something along the lines of this
