The best explanation of blockchain has to be (unsurprisingly) 3Blue1Brown: [this video] Would highly recommend watching this video for anyone who hasn't already.

this video is the best explanation for how mining and blockchains work IMO: [this video] It's long but very clear and thorough.

Mining and facilitating transactions, by which I'm assuming you're meaning certifying that transactions are legit, are the same thing. Here's a short video by 3Blue1Brown on how cryptocurrencies work: [this video]

For a high-level introduction, this article in The Economist is where I'd advise someone to start: [LINK] Then, to make things feel more grounded, watch this video of a maths teacher walking you through the mechanics of what actually happens.
