Introduced as a groundbreaking technology, the chain of blocks usually called “Blockchain” consists of a low-cost communication, decentralized, secure digital storage. Working without intermediaries, a blockchain constitutes a database that contains the history of all exchange operated between its users since its creation.
Underlying architecture of the electronic currency Bitcoin created in 2008, the blockchain is being updated in real time and would be forgery-proof according to its developers because stored simultaneously on dozens of thousands of separate computers. Blockchain would thus bring a threefold revolution.
The first one would be to do without intermediation – e.g. banks, notaries – in our transactions thus directly operated between you and another user. The second one would be the emergence of an inviolable traceability of all exchange therefore allowing the authentication of the users and the verification of the delivered data – e.g. diplomas, contracts.
The third one would be of societal nature with the full decentralization of our way of life, this way opening significant political, economic and social prospects – e.g. vote, anti-corruption, monetary dematerialization.
