A blockchain is a decentralized encrypted data base which works thanks to collective network and with the goal to permit simple sharing transactions in P2P (peer-to-peer). A blockchain is made of blocks which are added one after the other following a complex IT protocol.

To work, a blockchain needs a global consensus

To enter a new data in a block–in order to archivate it for ever in the blockchain–, a consensus is needed. A block can receive thousands of datas. The computing power of several computers is used to validate the compliance of information with a predefined protocol. So it is based on a hard protocol that different computers have to resolve in order to create a new block after having being validated by the whole group (called “node”).

This method has notably made emerge smart contracts that allow the automatic execution of a task, outside any outside intervention.

Decentralized, concensus, trust, transparency, traceability, smart contract, transaction … a little list of keywords which enter in the definition of a blockchain’s IT protocol. Here, the community manages human activities, and not a central power … More over, this method brings much more security that our traditionnal data bases.

blockchain and cinema : a love story is about to born

In the cultural field, particularly in the film industry, the blockchain technology could make it possible to optimize the financing of works and creations by the various historical stakeholder, while making possible the opening to new modes of financing.

It also suggests the possibility of moving towards a disintermediated approach at different stages of a creation, renewing, for instance, the remuneration of authors. Blockchain technology is also seen as a tool against piracy, since it can guarantee that content can not be released outside the pre-defined circumstances. In this, it is a fierce guardian of respect for the rights of creators and rights holders.

Bypassing the need for banking intervention, a blockchain makes it possible to reconsider microtransactions and to include them in new economic models!

Therefore, an era in which we would ask ourselves “how did one do without blockchain?” seems close. And what is more coherent than a collective technology at the service of a collaborative work, finally?
