  Crowdfunding has become a popular form of collective funding, in which small
donations or investments, made by groups of people, support the development of
new projects in exchange of free products or different types of recognition.
Social network sites, on the other hand, promote user cooperation and currently
are at the basis of any individuals cyber-interactions. In this paper, we
present LikeStarter, a blockchain-based decentralized platform that combines
social interactions with crowdfunding mechanisms, allowing any user to raise
funds while becoming popular in the social network. Being built over the
Ethereum blockchain, LikeStarter is structured as a Decentralized Autonomous
Organization (DAO), that fosters crowdfunding without the intervention of any
central authority, and recognizes the active role of donors, enabling them to
support artists or projects, while making profits.
