Bitcoin Video Tutorials

[tobasco]

I've been making some educational videos on how bitcoin works.

My aim is to explain how bitcoin works in a way that is easy to understand. So if you're looking for a guide to how bitcoin actually works under the hood (without getting lost along the way), these videos may help you to get going.

Here are the videos I've made so far:

1. Mining

• 08:39 - Hash Function
• 13:55 - Mining Basics
•  ↳ 23:03 - Target

4. Script

An explanation of how Script works, which is basically the mini-programming language used to create the locking mechanism for bitcoins.

this is very helpful to me, you know .. some time I got tired of reading some explanations about mining and something else, but this video is more easier to understand especially for beginners like me, so I am very grateful to you that have made the explanation video, and I think any other beginner who wants to know about mining should see this video

Thanks for your hardwork, now we don't need to look for basic stuff about bitcoin.
