Who this course is for
Open Learning Path is for curious beginners: people who keep hearing words like "blockchain", "hash" or "smart contract" and want to understand what is really going on underneath. No maths beyond simple arithmetic is required, and no previous knowledge of computers beyond everyday use.
It is not a course about markets. We do not talk about prices, and we will not help you decide whether to acquire any crypto-asset. If that is what you are looking for, this is the wrong place — and that is deliberate.
How the path is built
The course has six modules grouped into three stages. Each module has three lessons, and each lesson builds on the one before it.
- Foundations (modules 1–2). Why keeping a shared record among strangers is hard, and the cryptographic tools — hash functions, keys and signatures — that make it possible.
- Mechanics (modules 3–4). How blocks are linked, how the network shares information, how participants agree on one history, and what smart-contract platforms add on top.
- Context (modules 5–6). What a "wallet" really is, how people protect their keys and avoid scams, and how laws, money and society interact with the technology.
Inside every lesson
- Learning goals — two or three things you will be able to explain afterwards.
- Reading time and level, so you can plan.
- A diagram that shows the mechanism in one picture.
- Key takeaways — the lesson in four sentences.
- Three check questions with answers you can reveal.
- Sources — links to the original documents behind the lesson.
Tracking your progress
At the end of each lesson you can mark it as done. Your progress is stored only in your own browser (local storage) — we do not create accounts, and nothing about your progress is sent to us. If you clear your browser data or switch devices, the marks disappear; the lessons stay.
A suggested pace
One or two lessons a day works well. After each module, try explaining the main idea to a friend in two sentences — if you can, you have it. When you finish module 6, take the final quiz to see what stuck.
When a word is new
Keep the glossary open in another tab. Every term used in the course is there, defined in one or two plain sentences.
