Many expected more from blockchain, e.g., nothing less than turning the energy sector upside down. This didn’t materialise yet. However, there are features such as anonymity that may be also re-used for centralised platforms. In his paper, Michael gives an overview on what we cannot expect from blockchain but in which cases advanced privacy requirmenents can be satisfied.
