We need this for block consensus programs, for the difficulty adjustment.

Needed operations:

  • comparision (less than)
  • addition
  • subtraction
  • multiplication of a u160 with a u32 (asserting no overflow)
  • multiplication of two u160s (asserting no overflow)
  • division (not sure we need this one but listed for completeness)

The compiler should be able to handle this as well through an array of 5 u32s.
