For Bitcoin specifically, the hashing algorithm difficulty adjusts up and down depending on how high the hash rate is. This is because creation of new Bitcoin was designed to be controlled over time.

Perceptual hash functions aim to imitate human perception by focusing on the types of features that drive human sight and hearing.

What does hash algorithm actually mean? Find out inside PCMag's comprehensive tech and computer-related encyclopedia.

What are cryptographic hash functions? A cryptographic hash function is a mathematical algorithm that takes a data input, often referred to as a message, and produces a fixed-length encrypted output.

This algorithm is a type of cryptographic hash function (CHF), with the source data labelled as the message, and the output being called the hash value or just hash (the checksum, in this case).

Learn what an algorithm is with this KS1 primary computing guide from BBC Bitesize for years 1 and 2. We will define what an algorithm is and how they work.

So, an algorithm is the process a computer uses to transform input data into output data. A simple concept, and yet every piece of technology that you touch involves many algorithms.
