I saw answers for why you wouldn't want to use an `id` in the VC assertion. I didn't see many examples of why you would want to use `id`. Here are two: * You have a single-use bearer token (movie ticket, age token) that you want to determine if it's been used before or not. Identifiers like this are useful for that use case: urn:uuid:ddf810cc-c891-11eb-9fd3-67046f0b67f0 These sorts of identifiers also compress well when using CBOR-LD (to 16 bytes) and help when encoding to QR Codes. * You have a public Verifiable Credential where you might want to publish other information, such as an HTML representation of the VC. An Open Badge URL might be a good use here. There are other uses, but they tend to be fairly use case specific and thus, esoteric. -- manu -- Manu Sporny - https://www.linkedin.com/in/manusporny/ Founder/CEO - Digital Bazaar, Inc. blog: Veres One Decentralized Identifier Blockchain Launches https://tinyurl.com/veres-one-launches
