The Stakers bucket is the 25% share of every base Buzz campaign pool reserved for registered $CGPT stakers. Stakers earn a proportional share based on their stake among all registered stakers in that campaign. The Stakers bucket requires no content creation; it is a separate lane from the Staking Boost.
The distinction between the two is worth holding onto, because they are often confused. The bucket distributes a fixed share of the pool proportionally among stakers. The boost multiplies points a participant earns through activity elsewhere.
Registration is the condition. A stake that is not registered to the campaign does not enter the proportional calculation, regardless of size, and the share is computed against all registered stakers in that specific campaign rather than across Buzz as a whole.
