GoLang implementation of how blockchain achieves immutability

In my previous article, I theoreticized on How blockchain achieves immutability.

Time to focus on practice.

Liquid error: internal

Let me know if you have any questions or doubts about the theory or this particular Go code, I am happy to help, answer!

Very nice. The CS behind block chains is very cool.

But the "immutable" part dissapear if someone gets 51% of the network with a far superior computing power and rewrites the blocks. There are also other ways of cheating but is not the point

Hey Adrian, I am glad you like it! Yea what you are saying is true, technically speaking you can also remove your blocks locally or re-write them before distributing but doesn't mean it's not immutable. In another words, all documents in your google drive are safe before they are hacked :)
