The BlockChain is considered the new generation of Internet and it is based on the data’s decentralization.
These data are distributed in the various nodes that make up the BlockChain to guarantee its IT security; so data’s certification is one of the most important point of BlockChain.
BlockChain advantages are:
The data is always traceable, just like every transfer, and is always possible to trace their origin
All data is certified, transparent and easily verifiable by everyone
To validate the changes, made in the registry, the nodes must reach consensus
Central bodies are no longer needed and the data is managed without intermediaries.
