In the realm of privacy and zero-knowledge technologies, the concept of a group takes on a significant role. A group, in this context, is more than just a collection of individuals; it represents an anonymity set. This means that within the group, individual members' actions, characteristics, or identities become indistinguishable from one another, providing a way for individuals to engage in collective actions or share attributes without revealing specific information about themselves.
Anonymity refers to the complete concealment of a user's identity, while pseudonymity allows users to interact under a consistent but “disguised” identity.
A way to establish necessary trust between a set of participants by verifying certain attributes or qualifications of individuals, without necessarily revealing their full identity and letting users keep control over how the data associated with their identities is stored, managed and used.
