10.2. Between the 13th of October and the 4th of November, the Innovators will have to publish on the platform. All projects are submitted via a pitch (“The Pitch”).  All pitches are composed of 2 parts, a video pitch, and a textual pitch.

10.3. The video pitch can be no longer than 2 minutes, and is to be uploaded to YouTube as a public video.  If the video is longer than 2 minutes it will not be reviewed by judges beyond the 2 minute period.  

• For the rest, it is up to you, but we recommend structuring the video into 4 parts: 1. the problem, 2. the solution, 3. what you accomplished and 4. finally what you are planning to do next. 
• So you have 2 minutes to cover 4 topics. We suggest dedicating about 30 seconds for each topic, but you are free to be more flexible. When showing off the demo, we recommend you not doing a walkthrough and focusing on the 2-3 features that help the user the most. 

The link to the video will have to be submitted alongside to your project page on Taikai by midnight 4th November.

10.4. The textual pitch is composed of responses to the following 8 points and submitted via the Taikai hackathon platform. These are:

• Describe the problem you are trying to solve
• Describe what your project does exactly in layperson's terms
• Describe how it uses the API/SDK
• Describe how impactful it might be in terms of reduction and reach (in your case low reduction but high reach, in other words, running one API request through your proxy would make a very small total reduction in CO2 emissions, but the amount of API requests is gigantic, so it could add up to a massive impact)
• Describe how feasible it is for you to get to a production ready state with a bit of time or prize money; how feasible it would be for others to implement, and how likely it is that they would choose to use your tool if made available
• Describe what is your vision for how the solution you have started to build in this hackathon could make a difference to the world.

• The URL to the prototype app and/or code (e.g. Github + e.g. example.com/Carb22solution)

10.5. The video pitch and the textual pitch must be submitted on taikais platform for viewing prior to the submission deadline.
