"WebHash chains are a technique for decreasing this space requirement. The idea is to define a reduction function R that maps hash values back into values in P. Note, however, that the reduction function is not actually an inverse of the hash function, but rather a different function with a swapped domain and codomain of the hash function. " - Hash chain
