How Weights Work
Your Unique Humanity Score is the sum of the weights from all your verified Stamps. A higher score provides stronger evidence that you are a unique human.
The recommended threshold of 20 means that partners integrating Passport should generally require users to have a combined Stamp weight of at least 20 to be considered verified.
