khssnv / Запуск маяка экономики роботов
Created April 4, 2018 07:21
1. Скачать образ маяка по ссылке https://drive.google.com/open?id=1GNpthYTDtawb6MubbHZz2ahuzXjZIKbB
2. Импортировать образ виртуальной машины в Virtual Box с 1Гб ОЗУ и сетевым интерфейсом с доступом в интернет
3. Запустить, дождаться синхронизации блокчейна (parity warp, синхронизация с сетью Ethereum Kovan). После синхронизации AIRA сообщит свой адрес в сети
4. Отправить на адрес AIRA более 0,1 Kovan ETH и 0,1 Kovan XRT
5. После получения KETH и KXRT AIRA произведёт смену поколения. Это включит функцию маяка и её ROS API
