Hash Functions in Blockchain

Introduction to hash functions Hash functions are one of the most extensively-used cryptographic algorithms in blockchain technology. They are cryptographic (but not encryption) algorithms that are designed to protect data integrity. In a nutshell, a hash algorithm is a mathematical function that transforms any input into a fixed size output. To be cryptographically secure — […]
