Summary<\/strong>: During month-long CryptoBazar Hackathon<\/strong> in September, NKN attracted 157 developers<\/strong> who produced several high quality applications based on the NKN SDK. The top prize winner SpaceCats by Nikolay Perevozchikov\u2019s team<\/strong> is a 3D multiplayer game with amazing audio and video effects, and real-time playability. We would also like to congratulate 2nd place Danil Lykov<\/strong> and 3rd place Boris Koveshnikov<\/strong>, both of which developed different decentralized instant messengers. All these dApps showcase the real-time communication capability of the NKN protocol and our global testnet. Thanks to all the developers who chose NKN\u2019s platform: you make NKN shine!<\/p>\n

II. Highlights of September Hackathon projects<\/strong><\/p>\n

We have seen many excellent projects coming out of this hackathon. As an example, \u201cSpaceCats<\/strong>\u201d is a 3D real-time action game that supports multiplayer participation. Using NKN\u2019s true peer to peer network layer, SpaceCats is able to record real time multiplayer activity on the blockchain.<\/p>\n

After the developers submitted their final projects, Dr. Yilun Zhang<\/strong>, CTO of NKN, led the NKN development team to review each project, communicate with the developers, and propose revisions to make their projects even better. In addition, the NKN team devoted time and resources to improve the NKN protocol and testnet. After several rounds of communications between the NKN team and the lead developer Nikolay Perevozchikov<\/strong>, the following improvements were made:<\/p>\n

    \n
  1. Added the new feature of multicast packets, which can significantly decrease traffic load on sender side when there are multiple recipients.<\/li>\n
  2. Added an option to disable buffering packets when recipient is offline.<\/li>\n
  3. Added smart contracts which can send\/receive packets. Real-time logic can be hosted on NKN blockchain.<\/li>\n
  4. Added subscription API to new blocks and transactions.<\/li>\n<\/ol>\n
