Using the proton fractal, the mechanism of baryogenesis has been revealed. From the mechanism of baryogenesis the law of baryogenesis is deduced. From the fractal mechanism, beautiful and simple mathematical equations which display the mechanism of proton formation are obtained. The equations allow us to obtain the fundamental constants of the proton. The proton fractal shows that there are many yet undiscovered elementary particles with masses in the range from the mass of the electron to the mass of the proton. A prediction of the mass spectrum of new elementary particles for their detection in experiments is given. The fractal theory of proton mass makes it possible to obtain the most important dimensional and dimensionless fundamental constants of elementary particles by calculation. These constants could not be obtained within the standard model. The law of baryogenesis was obtained as a generalization of the proton's structural genesis law. The proton fractal leads to the solution of the antimatter problem and reveals the mechanism of baryonic asymmetry. The proton fractal and the mechanism of baryogenesis reveal the fallacy of the conclusion about the predominance of matter over antimatter in the modern Universe.
