Blockchain platforms are emerging platforms and, at this point, nearly indistinguishable in some cases from core blockchain technology. They are being used for generalized distributed value exchange, consisting of an expanding list of cryptographically signed, irrevocable transactional records shared by all participants in a network. Each record contains a time stamp and reference links to previous transactions. It is a decentralized state transition machine that manages the life cycle of digitalized assets and immutably records operations in a distributed ledger. A digitalized asset can be any object with explicit or implicit value (such as digital currencies, securities, precious metals, commodities, materials, identity, credentials, patient health records).
