RE: BLOCKCHAIN FOR DUMMIES - what would be your explanation? [question from my recent interview]

in Project HOPE5 months ago

Hello @crypto.piotr
As usual you bring us a topic in which there will surely be a great participation, and surely you will be able to get some good ideas to face that question apparently always, but that for many is often difficult to understand.
Particularly I assume that any learning process is made easier if it starts from the knowledge that the person already has.
In this case, everyone knows what the Internet is, we could start from there.
And making an analogy, as for example, with the operation of the bank, considering that the data that are handled are of great importance.
Then, my approach for someone to understand what the Blockchain is would be to mention the above, while at the same time I explain the following as points of difference:

A bank handles the information in a main computer, which means that the information is centralized in one place. This means that it can be easily hacked, and that the data can also be manipulated, since it is only in one place.

Now, in the case of the Blockchain, this information is registered not in one but in several computers at the same time, in different parts of the world, which makes it practically almost impossible to modify. Since the information is not stored in a single site, but is distributed, which makes it decentralized.

At the same time it makes it immutable, because if that information is in 10,000 computers or more, in different parts of the world, you should change the information in all of them, and that is practically impossible. Therefore, in addition to being immutable, it is something that cannot be reversed, once the order to execute a transaction is given, it is carried out.

The Internet is like the technology that makes all these computers interconnected with each other and able to record that transaction, like a chain reaction...

I hope that this example serves to facilitate the understanding of what the Blockchain is to me.

Have a nice Sunday.
