Credential Map and Weights
The Stamp-based verification system uses a set of Stamps and underlying weighted credentials to determine the score of a Passport.
Stamps and credentials
Each Stamp partner or concept has their own Stamp that users can see and interact with see in their Passport. Each Stamp can have one or multiple underlying weighted credentials, which represent an identity verification activity within the Stamp partner's ecosystem.
The weights assigned to each credential represent how strong of a human signal the underlying verification activity represents. The higher the point allocation to a credential, the better the human signal.
Custom Passport
If you'd like to customize these credentials -- either remove them from your community's Passport or adjust the weights -- you can do so with Custom Passport
Custom Passport enables you to customize the Passport Stamp-based offering around your ecosystem's unique needs. Choose which credentials to include at which weights, and even create your own custom Stamps.
