Designing a set of equations that require extremely complex calculations to yield a fixed number of special solutions is not a difficult task for Zhao Yi.
No matter how complex similar systems of equations are, they surely can't compare to a three-dimensional seismic wave graph.
The core of Bitcoin is a complex system of equations.
Creating a "new Bitcoin" or designing a system of equations with better solutions and more complex calculations than those of Bitcoin, is not an impossible task.
Zhao Yi only contemplated creating this "new coin" for about ten minutes before losing interest, as he realized that there would not be much difference between the new coin and Bitcoin.
Bitcoin is not a product of significant mathematical or computer research.
Bitcoin was created under particular circumstances.
