Anders Brownworth gives a basic visual introduction to blockchain using an interactive web demo, covering SHA256 hashes, blocks, chains, distribution, tokens and coinbase transactions.
HN repeatedly recommends it as the best ground-up, non-hype introduction for people who want to understand what a blockchain actually is.

This is much more basic than academic level, for which you could maybe start with the original Satoshi Nakamoto Bitcoin white paper? - but this video is a fantastic introduction this video
My favorite: this video It explains from ground up without getting complicated - it basically demystifies the whole thing completely i give this to everyone - even to non technical people
If you're really wondering what a blockchain actually is, this video is a really good intro: this video If you want something a bit more hands-on, I'm currently following this course: [LINK] I have only made it through the first section, and it does a really good job of explaining the basics of Ethereum and what a smart contract actually is.
Intro: 1. [LINK] 2. [LINK] 3. [LINK] 4. this video 5. [LINK] 6. [LINK] Build Your Own Blockchain: 1. [LINK] 2. [LINK] 3. [LINK] Resource List for an Advanced Understanding (Multidisciplinary Approach): 1. [LINK] --- Additionally, here is some advice from Balaji Srinivasan (source: [LINK] ): 1. First, I'd master database and cryptography fundamentals, with something like Dan Boneh's course for the latter 2. Then, I'd read the Bitcoin.org and Ethereum documentation 3. Then, you should write short Python or Go scripts to do things like printing out the blockchain, formatting and signing a transaction by hand, managing private keys, that type of thing. This will give you a feel for the raw data structures. 4. After doing all this, I'd take a look at application libraries like Ryan Shea and Muneeb Ali's new blockstack.org The reason I'd do it in this order is that you would learn fundamentals first before proceeding to the cutting edge.
Great looking tool, thanks. Looking through your "Futures" on the README I do think ... "Add videos demonstrating common concepts and attacks (such as race attack, finney attack etc)." ... would certainly make it accessible to a wider audience which, given the amount of effort you've put in, seems like a good idea. Something like these two videos, only based on your tool, would be very good - to this video (Part 1), [LINK] (Part 2) .
