One arrow in a pirating scheme quiver is the false claim to work or authorship or ownership. With Blockchain one can ascertain proof-of-work and proof-of-authorship if they upload their work, comply with Blockchain agreements and get their digital certificate which includes a private key, kind of a personal signature.
This can prove ownership of the works as it is time-stamped and known to be in existence. One can also trace the transactions and copyright use of their works and be able to calculate the intellectual property value in the forms of royalties and license fees and any other form of exploitation either economically or morally.
For a long time, creatives have decried the often rigid and unclear remuneration process of their royalties, the blame always shuttling between collective management organizations, CMOs and the broadcasters.
