This is primarily a demonstration of how cash instruments can be decentrally issued. Secondarily, it demonstrates how we can move validation from physical properties of cash instruments (such as fine printing and exotic inks) to cryptographic properties. We believe the latter to be superior and a path to ratchet down the cost overheads that go into securing cash issuance and payment channels.
