What is being proposed by Blockchain Book?

An experiment by Google Creative Lab Sydney’s Tea Uglow

Books you have finished reading may be passed on to your offspring or taken to a used book store, but with electronic books, their ownership is rather uncertain to begin with. This is because the reader merely purchases a license. Books from “Editions at Play” launched by Google this spring are part of a project that uses the distributed database Blockchain, which is the core technology behind Bitcoin. Its developer, Tea Uglow of Google Sydney, questions the future of electronic books through her experiment.
