In Bitcoin, hash functions are used for transactions, block hashes and addresses. Two hash functions used in Bitcoin are Hash SHA-256 and Hash RIPEMD-160.

A quick guide on `How the hash of Bitcoin block is calculated?

He nailed it right on the head. I have been using this tool (https://sha256algorithm.com/) to better understand how it works at a more technical level but it takes time. This tool enables you to hash anything and walk through each and every step to fully understand what happens at each and every step. I have also been lucky enough to have one of the cryptographers at a local meetup help me to understand things but it's an uphill battle.

Please guys,what type of hash functions is used when there is a variable number of items to be hashed,such as the many state changes in a block?

A Merkle tree or hash tree which totals all the various number of hashes. https://www.includehelp.com/mcq/what-type-of-hash-function-is-used-when-there-is-a-variable-number-of-items-to%20be.aspx
