Achievement of immortality was the main practical goal of most inhabitants of teralopolises, which in turn required the accumulation of a sufficient amount of binary material. Digital currency no longer interested people. Everyone wanted to get binary particles. However, only ideas may have been tied to the memory of the soul, which hampered the turnover of subtle matter among people. The demand has spawned an offer, and the solution was found.
Was determined the cheapest and simple idea available to human consciousness - a circle originating at a point. Circle in all its conceivable manifestations became the minimal binary unit - the new currency, the reference measure for determining the price of any phenomenon of reality. Binary currency used in various nominal scales, which was very convenient and enabled to store in the mind of even one person, millions of tons of binary material, ready at any moment to recreate the objective form of any conceivable idea.
The idea of a three-dimensional sphere many times exceeded the value of the idea of a two-dimensional circle. Many Soliats could consolidate their binary reserves in four-dimensional, five-dimensional and six-dimensional spheres, depending on level of abstract thinking. Binary currency gradually supplanted digital money and become a pinnacle of human exchange system.
