Anders Brownworth explains the fundamentals of blockchain technology, including SHA256 hashes, blocks, and distributed ledgers, using an interactive web demo.

This is a very basic visual introduction to the concepts behind a blockchain. We introduce the idea of an immutable ledger using an interactive web demo. Intro SHA256 Hash Block Blockchain Distributed Blockchain Tokens Coinbase Transaction Part 2 is here: youtu.be/xIDL_akeras If you are interested in playing with this on your own, it is available online at: andersbrownworth.com/blockchain/ The code that runs this demo is also on GitHub: github.com/anders94/blockchain-demo I'm @anders94 on X.

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 link to this video

My favorite: link to 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: link to 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.

In every post i've made it has been crystal clear I'm referring to "blockchain the data-structure"... The "consensus component" is an algorithm for detecting if one blockchain disagrees with other blockchains, and ignoreing it if it does. link to this video

Intro: 1. link 2. link 3. link 4. link to 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 str…

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 link to this video (Part 1), link (Part 2) .
