I'm trying to summarise in a generic form, the underlying processes within any blockchain... ie: Explain it to people without technical backgrounds. I've ended up merging a few of the ideas, and coming at it from a weird perspective.. how does this seem?
--------------------------------------------
Part of its process (Im merging and simplifying here) involves having many peoples computers store a copy of the information. When something needs to happen theses computers do a series of computations. The process only completes when these computers reach consensus many computers agree that the final result, the output of the work, is valid. If someone is acting up, they are identified by their inability to concede.
--------------------------------------------
Explain it for simple humans isn't easy, but you go with parts... First you can explain why it's like a DataBase because it goal is to save a lot of information relevant to the system, then you can explain how is like a P2P network, at end each block get updated in each core and that way everyone has the same information, and after that you can explain about the blocks and the confirmations, explain that would be the hard part but with some imagination will be possible.
