Just like in a physical world where a person can have a card for shopping, an identity card based on citizenship or a driver’s license card for driving, within Vereign, the idea of all these different cards is represented by the term passport. Similar to the different cards, a user can have different passports for different occasions. For example, one for interacting with friends or several for interacting with different government systems. By selecting a passport, a user selects a specific set of data, rights and keys to use.
The passport represents a connection endpoint for the users, known as entities, to interact and exchange information within the system. Another word which can be used to describe the notion of a passport is identity. As one entity can have many identities, it can also have many passports.
A single passport contains a specific list of claims that an entity has created. Only an entity of a type of person, asset or organisation can extend itself and have a passport. Furthermore, a passport can be extended with the ability to have documents and emails attached to it. Currently, passports don’t support documents.
