Blockchain 101 - Part 2 - Public / Private Keys and Signing

This is part two in my basic visual introduction to the concepts behind a blockchain. We build on the concepts from the previous video and introduce public / private key pairs and signing using an interactive web demo.

If you are interested in playing with this on your own, it is available online at:

The code that runs this demo is also on GitHub:

This 2 Part series you've made needs to become the worldwide standard for teaching this subject. No where has anyone I've ever met been able to describe this in such clarity. All that come across your instruction will leave well informed, thanks to your efforts (myself included).

I have had to turn comments off on my blockchain videos due to spam. If you want to reach out to me, please find me on twitter @anders94 instead.

Most of the recent comments (which I've been judiciously deleting these past few years) have been people pushing an "I can get your private keys back for you" scam which, as everyone who has watched these videos knows. is quite impossible. I hate to take such a drastic measure but I'm afraid I just don't have the time.

I have never seen such an elegant simple and MEANINGFUL demo anywhere. Everyone just talks big, and confuses more! Thanks a ton.

[xpressabhi]

I don't usually comment on Youtube videos. But you have done a hell of a good job in explaining the entire concept so easily. Thanks very much!

I believe visual learning is one of the best methods to understand concepts and thank you so much for investing time and developing stuff for this 2 part block-chain video series!

Saved me 3 days of research. So perfectly explained is crazy. Thank you very very much 🤗😁

[Andrew-igsp]

This video and part 1 are the videos I send to anyone asking me to explain what a blockchain is. So clear. Thank you for making these!

[vittalshenoy]

Thank you for crystal clear explanation. Nowhere will you find such detailed yet comprehend-able video...

Just wanted to say thank you for this great explanation of this, my group in collage is working on a Block chain project for school and this really helped me explain how it work to them.
