The blockchain applied to the traceability of products, raw materials, manufacturing processes in the production supply chains will significantly change the way in which information is shared between companies in the coming years, ensuring flexibility and security in transactions.
A blockchain can be defined as a family of technologies in which the register is structured as a chain of blocks containing transactions and whose validation is performed by a consent mechanism, distributed on all the network hubs in the case of public blockchains or on all the hubs that are authorized for the validation process of transactions to be included in the register in the case of private blockchains. The main features of blockchain technology are the unchangeable register, transparency, transaction traceability and security based on encrypted techniques.
The blockchain allows to manage a database in a widespread way, from an operative point of view it is a valid alternative to centralized archives and it allows to manage the updating of data with the cooperation of the network partners and with the possibility to have unchangeable data, which are shared, accessible and delivered to all partners. This allows data management in terms of audit and approval without the need for a head office. We can define the blockchain as a new generation of the Internet or even better an Internet of transactions with a new concept of trust. This is why the blockchain must be considered as a digital platform that allows the development of a new form of social relationship, and which, thanks to everyone's contribution, is able to guarantee the possibility to verify, to control, to have total visibility on acts and decisions, which are recorded in archives that are unchangeable and therefore immune from any corruption.
