THIS WEEK’S News and Reports

Hitters Xu at Columbia University

Nov 9th, Columbia University, New York / Nebulas Meetup

It’s the first time for Nebulas to make a public meetup in New York. Nebulas Founder Hitters Xu made a speech: Blockchain Search Engine, Discover New Value of the Blockchain World. Many Columbia University students and people who are interested in Blockchain came that night. From Silicon Valley to New York, we met various users with pleasure. We’d like to share with people, welcome to build the Nebulas Community with us.

Columbia Blockchain Lab organized this meetup and The Lion Network co-sponsored it.
