This question of power and authority is vital in identity systems. We can ask "what do we give up and to whom in a given identity system?" I argued that the architecture of SSI, its structure, made those relationships more authentic. Figure 1: Binding of controller, authentication factors, and identifiers in identity systems.

Because DIDs are cryptographic artifacts tied to public-private key pairs, this exchange provides the agents with the means to perform mutual authentication and create an encrypted channel. This is sometimes referred to as self-sovereign identity (SSI). These agents exchange decentralized identifiers (DIDs) to create a relationship 2.
