Expand description

Policy on the credential of the account.

This is one of the key features of the Concordium blockchain. Each account on the chain is backed by an identity. The policy is verified and signed by the identity provider before an account can be created on the chain.

The type is parameterized by the choice of Attributes. These are either borrowed or owned, in the form of an iterator over key-value pairs or a vector of such. This flexibility is needed so that attributes can be accessed efficiently, as well as constructed conveniently for testing.

Fields

identity_provider: IdentityProvider
Expand description

Identity of the identity provider who signed the identity object that this policy is derived from.

created_at: Timestamp
Expand description

Timestamp at the beginning of the month when the identity object backing this policy was created. This timestamp has very coarse granularity in order for the identity provider to not be able to link identities they have created with accounts that users created on the chain. as a timestamp (which has millisecond granularity) in order to make it easier to compare with, e.g., slot_time.

valid_to: Timestamp
Expand description

Beginning of the month where the identity is no longer valid.

items: Attributes
Expand description

List of attributes, in ascending order of the tag.
