ELI5 ECC is a widespread way of dealing with the public key cryptography keys generation. Elliptic Curve Cryptography The figure above illustrate how to get the point 8G starting from an origin point G. It works as: Pick a generator point (G) that belongs to the curve; To get 2G, which is in fact the sum of G to itself, you draw the tangent of the G point and then find the point that it hits the elliptic curve. This point will be -2G; Reflect this point over the x-axis to find the 2G; Now to find the 4G, find the tangent of 2G and do the same process above. Once you find it, do the same to find 8G. You could also do it in a different way: after finding 2G, you could add 2G + G to find 3G by drawing a line defined by 2G and G, finding the intersection with the curve and then reflecting over x-axis. ...
