Since this month, two large-scale blockchain events have been held in Hong Kong. The two series of events, "Hong Kong blockchain week" and "Asia encryption week", are both industry-leading in terms of guest specifications, duration and number of participants.The author observes that under the background that the blockchain industry as a whole has not yet come out of the "winter", thousands of people from more than 50 countries and regions participate in the industry event in Hong Kong, and there are still hundreds of projects seeking for funds. Participants from different backgrounds keep exchanging new knowledge, which seems to indicate that the industry is accelerating to recover.
