Round 1: Community Judging

In Round 1 of the #BUIDLathon, #BUIDLers showcase their projects to a panel of community judges who possess expertise in various fields, such as technical engineering, smart contracts, business development, UI/UX, legal/compliance, and security. Each judging panel is tasked with reviewing all submitted projects to the track, asking technical questions, and selecting their top three projects based on this year’s judging criteria.

2023 Judging Criteria:

  • Best for Blockchain: How much does this project improve the Blockchain ecosystem (e.g. giving developers better tools, driving adoption, improving the architecture, etc.)?
  • Best User Experience: How easy is it for experts and amateurs to use this product/service?
  • Best Engineering: How impressive is the technical implementation? How well is it engineered?
  • Highest “WOW” Factor: Did this project get you excited? Are you impressed?
  • Most Innovative: How original, creative, novel, and useful is this project?
