Make sure you really understand what’s going on behind the scenes. For example, for project 3 in 161, initializing the min and max variables to the users first value choice is critical for that project, make sure you understand that process and why that is so important. The rest will come with time and practice.3. User Struct corruption: Because each user struct is Encrypted and Signed with Keys deterministically created based on the user’s username and password, each user is stored in the Data Store with Integrity and Authenticity.
