An excellent project with massive potential implications for the data storage industry. I am in the process of building a social media and business network, with distributed storage services rewarded by the blockchain. I hope to use a similar proof of storage mechanism to enable network Supernodes to host files for user posts, and earn rewards. The Sia project was a large inspiration for this aspect of the Ezira network storage design. Comments and suggestions to implement this functionality into the Ezira network are appreciated. PM me for further details.
