explain distributed ledger technologies principles

Explain the principles of the system architecture underlying distributed ledger technologies (DLT), in particular blockchain. Understand the DLT system architecture in terms of functional components in the core and service layers, the application service platform, DLT services, and external services. Understand the interaction of these components to provide DLT-based functions such as consensus mechanism functions, ledger management functions, smart contract mechanism functions, and distributed application management functions.
