Mediachain

It serves the role of a traditional database, but is a decentralized, global data layer for powering serverless applications. It is a single port of entry for applications and users to publish, discover, and collaborate on media metadata. With Mediachain, a group of museums can collaborate on cultural heritage data in a shared system, a cooperative of openly-licensed image sharing platforms can publish attribution information to a community-maintained ledger, a consortium of music industry organizations can share rights data without ceding control to a third party, and a developer can build a decentralized blogging platform without needing to run a centralized database.
