Blockchain represents a new kind of Trust, in the digital world.
It is a technology that develops a new type of relationship between the production sectors, allowing everyone the opportunity to verify, to have total transparency on all operations: every procedure, every decision is recorded in immutable and shared archives having the characteristic of being unalterable, unchangeable and therefore immune from corruption.
How does it work
It includes the sharing of a register between the nodes of a network (nodes are the participants of the blockchain and are physically constituted by the servers of each participant). This register is structured like a chain of blocks containing the transactions – that is data that represent the values object of “exchange” and that need to be verified, approved and then archived – and whose validation is entrusted to a consensus mechanism, distributed on all network nodes. The main features of blockchain technologies are the immutability of the register, the traceability of transactions and the security based on cryptographic techniques.
