The Global GraphHack has officially started, with over 450 registered hackers participating in the world's largest graph hackathon. The theme is extending the graph ecosystem, and participants are encouraged to build something using or extending Neo4j that benefits others in the community. A combination of community votes and a Neo4j panel of judges will determine the winning teams, with judging criteria including creativity, usefulness, completeness, and quality and clarity of written documentation. Participants must submit their project directly on DevPost, publishing code to GitHub and creating a 1-2 minute video explaining their project. The top three winning teams will receive prizes such as flight and hotel vouchers, free tickets to GraphConnect 2020, and private access to the invite-only Ecosystem Summit.
