A hash is the output result of a hashing algorithm, which creates a unique, fixed-length string to encrypt and secure a certain selection of arbitrary data.
In addition, hashes are essential when using block explorers because they allow for the quick extraction of information regarding transactions and addresses. Hashing data is one of the most secure data transfer practices because none of the original information can be accessed without a hash key.
The hash and hash algorithm were created by Hans Peter Luhn around 1950. He started developing a machine that can quickly sort through both text and numbers, and thus the hash was born. While, at the time, there weren’t so many complex applications of this discovery, since then, the hash algorithm has become a cornerstone of advanced computing. Hans Peter Lunh was an innovator far ahead of his time, however, his inventions are now utilized in virtually any software available. While the term hash was not officially coined until Herbert Hellerman's “Digital Computer System Principles” was published, Hans Peter Lunh is considered the inventor of the technology.
There are numerous different types of hash functions, all focusing on various aspects of the hash algorithm. Fibonacci hashing is one of the more popular hash algorithms, and it involves multiples of the Fibonacci number. Other types of hashes include Zobrist hashing and various combinations between Fibonacci and Zobrist algorithms.
