Nov 25, Shanghai: Tongji FinTech Meetup

On Nov 25, Hitters returned to his alma mater, Tongji University, to share with the Fintech department on the topic of “The world of Blockchains and how it should be valued”.

During the session, Hitters shared his entrepreneurial journey of how he founded China’s first public blockchain, NEO, to his current newly founded company, Nebulas. He also touched on the concept and nature of blockchain system; how blockchain provides value confirmation and how a token act as the transfer of this value. Hitters went on to elaborate about Nebulas’ decentralized, open-source blockchain network and its fundamental framework. With an open-source algorithm, verifiable computation result and distributed storage, Nebulas went one step ahead of Google, achieving “Can’t be evil” instead of “Don’t be evil”, opening the doors to a new world.

Hitters also pointed out that with the launch of Nebulas test net next month, it’s just the beginning of exploring the new world and the real beginning of how blockchain innovation can change the world.

After the sharing session concluded, non-technical attendees understood more about blockchain and its uses. Eager to find out more, Hitters encouraged the attendees to join Nebulas’ rich ecosystem to understand more about the real value of blockchain and the limitless opportunities waiting to be discovered in the technology and more importantly, to make the blockchain ecosystem even stronger!
