Each blockchain is identified by a 64 character hash. This hash is composed of the 16 characters of the hexadecimal code (0, 1, 2, 3, 4, 5, 6, 7, 8, 9, a, b, c, d ,e ,f). A special typeface was designed to represent those 16 characters in order to depict the 64 character hash as an image. Each hexadecimal code character is visualized by a 16 character 4 x 4 square consisting of 15 dots and a space, which makes the whole hash into a 960 dots and 64 spaces square, 32 symbols long on each side.
