We should add:
- Discriminators are data written to account that determines the type of data stored inside
or something similar to make sure people know what they are.

Yes adding it. Also, should I add a section to explain the concept?

More of complaint with the old lesson, but is a discriminant the same thing as a discriminator? This is confusing.

Yes it's a bit confusing to me as well initially but discriminant manages enum variants internally in the Rust and discriminator is an explicit identifier used to distinguish different account types within Solana programs.
@mikemaccana Answered the questions and resolved the comments. Let me know if there is any additional feedback. |
