Blockchain-based digital ID is based on the principle of self-sovereign identity (SSI), whereby users can share selected information with vendors or service providers instead of their entire identity. The analogy is of a person walking into a bar and presenting a trusted credential that only showed they were of legal age to buy an alcoholic drink – instead of presenting an ID card that might also reveal their name and address details.
