Too Long; Didn't Read
A new paper published by Microsoft's research department proposes to tackle piracy with a bounty system titled "Argus" The system allows volunteers to report piracy in exchange for a reward. Microsoft is one of the world’s most prominent copyright holders with a vast experience in fighting piracy. The system uses the Ethereum blockchain and is transparent, practical, and secure, while limiting abusive reports and errors. Argus is an open system but there are various safeguards to prevent abuse. It theoretically works with various media types including images, audio and software.
