A hash rate may refer to computations in a single GPU in one computer, a crypto mining machine, or hundreds of machines in a mining datacenter (see ASIC miner). See cryptographic hash function ...

At the same time, there isn't a good theory of hash functions. Unlike encryption algorithms, there are no secret keys involved; this makes it harder to mathematically define exactly what hash ...

Hash functions are a popular building block used in designing secure cryptographic protocols. Bitcoin, for example, uses the hash function SHA-256 in its proof-of-work. (SHA stands for "secure ...
