Once a "variable" (a constant, to be precise) is named in Haskell, it will always mean the same thing. In Haskell you cannot say that a variable is equal to the number 3 and then say it is equal to the number 10.

Why is the purely functional paradigm desirable in cryptocurrency and blockchain software development? There are many reasons for this, but we'll approach some of the most important ones.įirstly, purely functional programming means that data is immutable and only functions can manipulate input and produce a different output. Cryptographers usually come from these fields of study, so Haskell is slowly growing within the cryptocurrency development field. This functional purity makes Haskell a favorite language of mathematicians, logicians and FP enthusiasts. It is unique in the fact that it does not allow any exceptions to the functional programming paradigm, unlike mixed functional/object-oriented languages like Scala and OCaml. There are other purely functional dialects, but they're usually limited to domain-specific applications. Haskell is the world's only widely adopted general purpose purely functional programming (FP) language. We briefly discuss each language while highlighting their main characteristics, learning difficulty and how they are deployed in different crypto software projects. In this article, we take a look at cryptocurrency projects and the languages they employ. Many different computer programming languages are employed in cryptocurrency programming.
