The two main hash functions used by Bitcoin are:. (returns 160 bit unsigned integers) Sample hash values.Note that once the method is widely disseminated and adopted by other miners, the computational power imbalance straightens out again, and the difficulty of the hashing problem can be scaled accordingly.
In the previous post we have explained the ideas behind the Bitcoin system, however, one issue remained unexplained: What is this bloody hard puzzle that the Bitcoin.
