Создание смарт-контрактов Solidity для блокчейна Ethereum. Практическое руководство

Фролов Александр Николаевич

В качестве параметра –etherbase нужно ввести адрес узла, полученный при первоначальном создании аккаунта.

На экране появится множество сообщений о ходе инициализации. В ходе этого процесса будет запущена генерация файла DAG. Вам нужно будет дождаться завершения процесса генерации:

зависимости от производительности вашего виртуального или физического сервера генерация файла DAG может занять несколько минут или дольше.
