IdentityName¶
Purpose¶
Serves as an alias for an ExternalIdentity in Anoma. This is useful when we do not yet have the (cryptographic) specifics for an identity, but we want to refer to it anyway. These are resolved by the Name Engine.
This implements the Identity Name Abstraction from system_architecture.
This means that, as far as our SML is concerned, we will need a structure
matching the VERIFIER_NAME and ENCRYPTOR_NAME signatures, where the
identityName type is this IdentityName.
Type¶
There are (infinitely) many ways to make an IdentityName, so this is a sum type. Each element also specifies here what kind of IdentityNameEvidence is necessary to prove that a given ExternalIdentity corresponds with this IdentityName, as used by the Name Engine. At the moment, we support 2 types of IdentityNames:
One of:
LOCAL_NAME- Structure:
string - IdentityNameEvidence: NONE
- The Name Engine must know any Corresponding ExternalIdentities
at launch (from configuration). These may include, for example:
- "localnode" representing this node's ExternalIdentity
DOT- Structure: Pair of Parent : ExternalIdentity, Child :
string - IdentityNameEvidence: a signed statement from Parent designating that some ExternalIdentity corresponds to Child.
- These implement the "." Notation Sub-Identity abstraction.
