During the summer, we have also supported NEL with their big game competition, which launched in May. For those who have not seen the competition yet, we strongly recommend you to visit NEO.Game. There are 39 prizes for game developers to win, with a total prize pool of 3.5 million RMB. NEL, together with NGD support, has held game events and game workshops through the whole summer, to get more developers to give a shot at blockchain based games.

This month also witnessed the successful conclusion of NEO London Meetup and NEO London Blockchain Challenge held during June 16-17. Johnson Zhao- NGD General Manager was invited to share his insights about NEO ecosystem at the meetup while the challenge was convened by Peter Lin – NGD R&D director.

NEO Blockchain Challenge is a new series of event launched this year, normally held more frequently with smaller group of participants than traditional hackathon. With a preference for pragmatic development-related issues, the new type of event will attract more local developers.
