    A verifiable claim is a qualification, achievement, quality, or piece of information about an entity's background such as a name, government ID, payment provider, home address, or university degree. Such a claim describes a quality or qualities, property or properties of an entity which establish its existence and uniqueness. The use cases outlined here are provided in order to make progress toward possible future standardization and interoperability of both low- and high-stakes claims with the goals of storing, transmitting, and receiving digitally verifiable proof of attributes such as qualifications and achievements. The use cases in this document focus on concrete scenarios that the technology defined by the group should address.
