Blog post: https://medium.com/cardstack/building-decentralized-media-registries-a953fd36d3d4

There are all kinds of registries in the world—both centralized and decentralized databases.

Chris Tse, Founding Director of the Cardstack Project, talks about the media registry use case in the enterprise space, and more specifically, the blockchain-based music registry Cardstack has built in partnership with Warner Music Group, Warner Chappell Music, and Dot Blockchain Media (the first phase of this pilot project / proof-of-concept was completed in Q2 2019).

Learn what it means to build a functional, scalable, searchable, version-controlled, and user-friendly media registry on top of the blockchain, and how the Cardstack Framework—as a general-purpose application framework—can help facilitate data orchestration, workflows, and permissioning for these decentralized databases. Cardstack, utilizing its own Gitchain technology along with blockchain software, can be used to build all kinds of collaborative registries, enabling multiple companies to come together and synchronize not only business processes, but data sharing.
