In recent months the rapid increase (and partial decline) of value of many crypto-currencies has sparked heated debates, often based on wrong and little known concepts.
A widely used term when talking about crypto currencies is "blockchain": it is the technology that underlies virtual currencies such as Bitcoinhowever, it can be used in a large number of different scenarios.

Thursday 29 March at the Oracle headquarters in Rome an informative meeting took place with the R1 Company presented by Paolo Gaggia (R1) and Matteo Mattei (Oracle) where the influence of blockchain in the economic, computer and scientific world was widely discussed.
La blockchain it is a public register, divided into cryptographic blocks constituting a "chain" (hence the term blockchain). Each block contains a series of encrypted information regarding the previous block (hash) together with timestamp, ie the information on the moment when the transaction in the blockchain has been carried out, the timestamp it is kept inside the chain, in this way it is guaranteed its security and authenticity, as to modify a block it would be necessary to modify the whole chain to which it belongs.
Furthermore, the blockchain uses a peer-to-peer connection (a network architecture in which there is no need for a hierarchy client-server, that is, every node in the network is equivalent), which makes it secure against attacks because the data are not recorded in a single potentially vulnerable database, it is in fact a decentralized system, where each node in the network has the same status as trust.
Le blockchain they are widely used in banking and economics but there are many potentialities such as quality control in a distribution chain, online voting service or Smart contract.
Oracle at the end of the event presented the technology based on Hyperledger, an architecture of blockchain for businesses, ready for use and managed in public or private cloud.
