Blockchain is a major technical discovery in computer science and it is contributing to advances in social and economics fields way beyond the digital world. Record, share, store, distribute data or value in reliable and transparent way, without corruption without relying on third parties, are the the promises of blockchain.
Data and value exchanges do not rely anymore on a single central point of failure but is rather built on top of peer-to-peer relation, in a decentralized manner ensuring complete robustness to the system. Transactions are authenticated and validated by computer nodes participating in the network. Every transaction is timestamped inside a block that it itself chained in a cryptographic ways to the previous blocks.
The autonomous distributed architecture of Blockchain is changing the notion of trust improving our society economic and social organization.
