When a task is defined, the number of points can be set as well.
This number is also used to award tokens if token payments are enabled on the project.
How do they differ?
Tokens get added to your wallet. You can earn the same token from different projects in many cases, and you can also exchange tokens for rewards.
Points are awarded on a per project basis and cannot be changed or manipulated in any way.
In this way, Tokens are great for value exchange – whereas as Points are used for things like reputation and leaderboard rankings.
