Hello, @blockchain_rio!
Looking to take a break amongst all the talks, panels & workshops? Welcome to #TheBlockchainOS lounge, a place where you can rest your feet and challenge your mind with a game of chess or battleship. Why those two games? Just ask our team 😉 https://t.co/FDOyDYugr3
你好，@blockchain_rio！
希望在所有会谈中休息一下，小组
