24. What type of hash function is used, when there is a variable number of items to be hashed, such as the many state changes in a block?
- Complex hash
- Simple Hash
- Tree-structured Hash
- Either
Answer: C) Tree-structured Hash
Explanation:
In the fields of cryptography and computing science, Hash trees, also known as Merkle trees, are a sort of data structure that stores a tree of summary information about a bigger piece of data, such as a file, and is used to validate its contents. Hash trees are a subset of hash lists, which are themselves subsets of hashing.
