One of the fundamental concepts to understand in order to deepen the knowledge of the world of blockchain and cryptocurrencies is that of the so-called Proof-of-Stake (PoS).
In order to delve deeper into this topic, it is necessary first of all to know what is meant by blockchain.

The true and unique great advantage of using a blockchain to record data is that in this way the database can be public, shared, searchable and verifiable by anyone, and above all managed
