Blockchain technology opens up the possibility for a provider to offer an immutable registry of transactions, held on a decentralized network of computers.
While financial applications continue to dominate the blockchain development landscape, as we’ve detailed in prior posts there are a growing number of companies offering registries for digital content, including Monegraph, ConSensys, Stem, Mediachain, ascribe and others.
A content registry, for the most part, is a registry of the ownership of intellectual property, most prominently copyright. Ideally, such a registry would accurately record original ownership of a work, and then also record all subsequent transactions involving that work. Since copyright interests are divisible, this can become an extremely complicated tree of transactions, very rapidly.
