A little horn would represent a little country. The countries have influence, but not as much as the whole power of the beast. So when the beast is seen with ten horns it speaks of influential countries in the world that are part of the system of the beast. One meaning of the number ten is completeness of order, so ten horns indicate how complete the involvement of smaller countries is with the beast, just as the seven heads of the beast show the involvement of major world powers. Upon the horns are ten crowns.
Crowns stand for authority and political influence.
So we further see the beast system coming through the authority in the world, the governmental and political system. The name of blasphemy is seen upon the heads. There's not a country in the world that's doing the will of God. They're all part of the beast system. To blaspheme is to speak irreverently or profanely of God, or to attribute something to God that is not of Him.
