@vaibhavgeek great work overall, but smaller PRs, and code relevant to the current PR would be much more easy to review.

The following project has been done as specified in the scope of the grant, a demo video has been uploaded (https://www.youtube.com/watch?v=_eVsyjWFXhw) which showcases Baseline Calendar.

The code can further reused for multiple different application which require membership proof.
