A blockchain system is a decentralized and open archive of information whose records (or blocks), made safe thanks to the use of cryptography, are continuously increased and distributed through peer-to-peer technology. Each block contains the hash of the previous block, a timestamp and the data of the transaction that once validated by the users themselves, and without the need for any security notion on their part, becomes permanent and can not be modified retroactively.

The blockchain technology revolution consists of total transparency, immutability, immediacy, security and distributed network logic where there is no longer any administration center so there can not be a predominant body but a system managed around a new trust criterion and a method for generating consent in order to authenticate transactions.

The development of blockchain technology, although it has found wide use in the fin-tech sector, finds applications in any sector of activity: cryptocurrency exchange, purchase of goods, exchange of computer data or any good that has an actual value; for this reason the blockchain is also called the internet of value.
