Nowadays, the most popular application of DLT concerns cryptocurrencies (Bitcoin, Litecoin, Monero, etc.), but the DLT features allow them to be applied in many scenarios, both in research and business contexts. In particular, the possibility of executing Smart Contracts makes the DLT technology suitable to be adopted in a large number of application fields, being Internet of Things, Cyber Physical Systems, Edge Computing, and Supply Chain Management, only some examples.
