Nowadays, you have probably heard the terms Bitcoin, cryptocurrency, crypto wallet, etc. in your day-to-day life. People usually treat it as an investment opportunity. But apart from that, the technology behind bitcoin, which is blockchain, is really amazing.

Blockchain is a new concept that works on the idea of decentralization. There is no centralized authority present in the blockchain. In traditional concepts, there is one centralized authority present which tracks all the activity of the user. But in blockchain, there is none. So, there is no fear of compromising all user's data when the central authority gets open.

Blockchain was initially intended to use in the field of money transactions but now, different fields are also trying to include it in their domain because of its security.

With the help of blockchain, it is almost impossible to cheat or hack the system. In this course, you will get to know the concepts behind blockchain technology, its importance, its key components, its data structure, and the key elements of blocks. In the last section, of course, we will create one very simple Django-based blockchain project which will perform simple tasks like; mining block, checking chain validity, and getting the entire chain.

Good luck and see you in the course...
