Verifiable Presentations
From the W3C's perspective, a "verifiable presentation" expresses data derived from one or more verifiable credentials, ensuring the verifiability of the data's authorship. Therefore, holders can extract specific information from their pool of verified credentials and compile it into context-specific presentations of personal data. These newly crafted composite proofs, or presentations, are then dispatched to verifiers, who assess their authenticity.
Essentially, verifiable presentations encompass three fundamental elements:
Presentation metadata
One or more verifiable credentials
Presentation proof
Based on the W3C's depiction of verifiable presentations, the illustration below illustrates the constituents and their interconnection. The presentation, denoted by the dark blue background, incorporates metadata (in purple) and references one or more verified credentials (with a light blue background). Similarly, the credential consists of metadata (in blue) alongside claims (in green). In this instance, the claim asserts that Bob, the credential's subject, holds a bank account with the specified number. The presentation and the credentials are accompanied by digital signatures as evidence of the data's validity.
