what is blockchain

The blockchain is a computer communication protocol based on peer-to-peer networks and cryptography. It allows thousands to millions of users of services and assets to be exchanged in a transparent, secure and decentralized way, with total traceability. The first blockchain was used in 2008 simply to exchange electronic money (bitcoin) without the intervention of a central bank. The rapid evolution of this technology has made it possible to develop more sophisticated applications, particularly on the Ethereum blockchain, which introduced Smart Contracts in 2013. These contracts automatically execute value transfers based on the fulfillment of predetermined conditions. These smart contracts are the concept and the fundamental technology for the deployment of the blockchain in the B2B environment. Indeed, their strong automation makes it possible to reduce the costs of verification, execution, arbitration and fraud. Because of its fragmentation and opacity, cinema is a privileged application sector of the blockchain.
