dc.description.abstractSince digital artworks are indeed digital content, they face the inherent problem digital content has: the link between content and its original author is very difficult to keep. Additionally, retaining control over digital copies of the content is also a challenging task. Digital coins have solved this very same problem through cryptocurrencies (for instance, Bitcoin) and have opened the door to apply the same techniques to other similar scenarios where ownership of digital assets needs to be preserved. In this paper, we propose BArt, a transparent and distributed mechanism for artists to commercialize their digital artwork, keeping control of the copies, monetizing its usage, and maintaining ownership. BArt allows artists to publicly register their work in the Bitcoin blockchain and sell usage rights in exchange for bitcoins. Buyers are allowed to exert the acquired rights. Proper behaviour from all parties is enforced by the system with cryptography and economic incentives.en
