The European Commission, the bloc’s executive arm in charge of introducing new legislation, said Tuesday that members of the European Union must be prepared to block crypto mining. The EU is also working on an energy efficiency label for blockchains, as the disruption of Russian gas supplies has some worried about high energy prices, blackouts, and shortages. In a document published on Tuesday, the commission said, “In case, there is a need for load shedding in the electricity systems, the [EU] Member States must also be ready to stop crypto-assets mining.”
