predict a cryptographic hash function

"Both the chaining, and the difficulty, are achieved via the SHA256 cryptographic hash function. The hash function essentially takes a block of data, and transforms it, in an effectively-impossible to reverse or to predict way, into a large integer. Making the slightest change to a block of data changes its hash unpredictably"
