Module concordium_base::id

This module and its submodules implement the Concordium identity layer, providing the core functionality for all entities involved (users, identity providers, and the chain).

Modules

• account_holder
  Functionality needed by the account holder, either when interacting with the identity provider, or when interacting with the chain.
• anonymity_revoker
  Functionality needed by the anonymity revoker.
• chain
  Functionality needed by the chain to verify credential deployments.
• constants
  Collection of constants that fix choices, be it values or types, that are used in various places.
• id_proof_types
  Types used to represent statements and proofs. A statement is what the user is requested to prove by the verifier. The proofs are for proving properties about the attribute values inside on-chain commitments that account credentials can have. Given the statement and relevant secret data (being the attribute value and the commitment randomness), the user can construct a proof of the statement (if the statement is true).
• id_prover
  This module exposes functions for proving statements about credentials on accounts.
• id_verifier
  This module exposes functions for verifying various proofs of statements about a credential on accounts.
• identity_provider
  Functionality needed by the identity provider. This gathers together the primitives from the rest of the library into a convenient package.
• secret_sharing
  Implementation of Shamir secret sharing.
• types
  Main types used in the identity layer, and their serialization implementations.
• utils
  A collection of auxiliary functions that don’t belong anywhere else.
