Regarding the specific application of blockchain technology in the copyright, it is assumed that when a work is uploaded on the Internet, it is difficult to maintain control, monitoring who is using the work and for what purpose. The use of blockchain technology, as an IP registry, affords tracing the “use chain” of the work through a system of licenses, sub-licenses and assignments, simultaneously disabling a licensee when its rights have expired. The blockchain offers an opportunity to record a digital work in a transparently and irrevocably way, giving the authors the evidence of the authenticity and ownership of own works; moreover, due to the absence of a centralized management direction, the sending of data takes place quickly, safely and economically, streamlining the chain of intermediaries and recording in an indelible way all the previous traces. The blockchain technology allows to protect the authorship of a work by inserting a frangment code containing all the most important informations: author, creation date, description, use licenses; by this way, counterfeiting a work is more difficult. Other advantages of the blockchain applications in this area are: the possibility of making micro-payments with minimal transaction costs; the transparency about the entire creative-production cycle; a simplified management of possible crowdfunding initiatives.
Today several companies deals with certification of copyright through blockchain technology, thus offering cheap and fast services. An example is Blockai, a platform that ensures to drag the file to be registered on the relative interface of the site, generating, by this way, a certificate that, due to the ID of the transaction, can not be counterfeited; another platform is Polline, which uses blockchain technology to protect the authorship of a digital work; once the protecting content is inserted into the blockchain, Polline issues the authorship certificate with the ID of the transaction and a certain date.
The capacity of theblockchain tecnology about tracing intellectual property rights could also have an application in the trademarks. As a widespread database that keeps track of every operation carried out in order to avoid possible frauds, the blockchain allows to check whether a potential trademark is identical or similar to existing brands; moreover, traces could be gathered about the effective use of a brand, immediately informing the competent offices and thus reducing the burden on companies to collect the relevant proof of use; finally, having the potential to create a unified global transaction system, the blockchain could afford the implementation of an intelligent IP registry system, recognized in several countries and which could serve as a centralized solution for registration and retention of all events concerning the life of a registered IP right.
