Learn how tokens move across blocks, how hashing works, and why blockchains cannot be easily changed.
Welcome! If this is your first time using blockchain:
Think of this lab like a digital notebook.
Each page is a
block once it's written, we do NOT erase it.
We only add new pages on top.
In this lab you will learn:
- What a block is
- How tokens move between people
- What a hash is (your security lock)
- How changing one block breaks everything after it
Try this:
- Change an amount or name
- Click Mine
- Increase difficulty and mine again
- Watch balances and colors change
