This is a review by the NIST (National Institute of Standards and Technology) of the hype around blockchain. They conclude that most people, surprise surprise, don't need a blockchain. There is a very simple graphic of the flowchart and a summary of their report here:

Personally, I didnt really understand blockchain until I wrote my own parser for a coin that didnt have a block explorer yet, you can see the results here if you want: https://www.xaya-gaming.net/. [xaya-gaming.net] It isn't that complicated to extract the basic info (getting all the TX info out efficiently gets more messy), people who know how to code should be able to do it in a week or so.

Blockchain is basically a name for something bankers call a ledger. Or in compsci terms. An immutable list. You add to it and never remove. The 'blockchain' bit is the cryptographic bits to insure lack of tampering. Some blockchains also have the idea of work. In the case of the most famous one you 'guess' the next in the chain and its yours. Some bright sparks decided that the payload is also money. Money can be anything from rocks to gold to bits. Just so long as everyone agrees it is worth something.
