Can a submission for the hackathon be a "backend only" delivery (smart contracts with its corresponding API and documentation), or must it be a full dApp including frontend?
Yes, it can! Here are the requirements to participate in the Keep it Confidential Hackathon:
-Provide a short summary of your project, including a description of what it is and how you want to evolve it
-Provide a link to your code repository for judging and testing. Code must be open sourced.
-Provide smart contract deployment links
-Include a video (less than 5 minutes) that shows how your project works and why you built it. Videos must be uploaded to YouTube, Vimeo or a similar site and made public.
