Hi @crypto.piotr friend, this is a very interesting topic.

The first thing I can say is that I entered the world of the blockchain without knowing "anything", in fact I still cannot affirm that "I am inside", however during my explorations I found a lot of confusing information, I had no one around to ask, and When I have asked a question, I always get confused or disoriented answers.

Finally, for me to explain to someone about the blockchain, first I make sure: 1) how willing that person is to learn; 2) why do you want to know; 3) what use will that information give you or what is your main objective with this information; with this I make sure that I am guiding my possible answer correctly.

Personally, it took me a while to understand the analogy and meaning of the term "blockchain", because only what is related to cryptoactives and in reality it is not, blockchains can be applied to a large number of different types of records, for example, lately In the educational area I have been participating in professional update courses in an academic platform based on blockchain, where there is no cryptoactive involved, and with this recent example I changed my personal perspective when I realized that the blockchain system allows somehow to make a record of activities and information, stores it, can make them a verification or check, and can even track data.

And I saw this personally on the educational platform that I mentioned earlier.

This is my point of view.

See you..!
