ExternalIdentity

Purpose

Designates an identity in Anoma. This could represent an internal component, or a user, or an Anoma node, etc. The External Identity encodes all the information necessary to encrypt messages to and verify commitments from some Identity represented.

This implements the External Identity Abstraction from. This means that, as far as our SML is concerned, we will need a structure matching the EXTERNAL_IDENTITY signature, where both the signer and the verifier type are this ExternalIdentity type.

Type

There are (infinitely) many ways to make an ExternalIdentity, so this is a sum type. Here we list some of the options that should be available.

One of:

  • ed25519
  • secp256k1
  • BLS
  • A Threshold Composition of External Identities.
  • This must include any information necessary about how, for example, secret sharing is done for threshold encryption.
