Hashing is a specific technical process in blockchain where transaction data is turned into a set of characters (letters and numbers).
All this is possible thanks to a mathematical algorithm, the hash function. Its length always remains the same.
The creator of the hash tree, or Merkle Tree, was the scientist Ralph Merkle. He created the concept to facilitate data validation in cryptography.
What are the properties of a hash function? hash is always unique
if the initial information changes, the hash also changes completely
hash is irreversible
hash function algorithm is usually open
Hash usage in practice: working with large amounts of information
optimization of data validation during transmission
reduction of the amount of calculations required
