Digital Identity

Digital identity encompasses the attributes, credentials, and representations that define who a person is in digital environments—from usernames and profiles to cryptographic keys, biometric data, and avatars.

The landscape of digital identity is fragmenting and consolidating simultaneously. On one hand, the average person maintains over 100 digital accounts, each with its own identity silo. On the other, federated login systems (Sign in with Apple/Google), decentralized identifiers (DIDs), and self-sovereign identity protocols are attempting to give individuals portable, user-controlled identity. The EU's eIDAS 2.0 regulation mandates digital identity wallets for all EU citizens by 2026, creating the largest government-backed digital identity infrastructure in the world.

In the metaverse and gaming context, digital identity has evolved from static profiles to living expressions of who people are and what they've accomplished. Virtual items, achievement histories, social graphs, and creative portfolios all constitute facets of identity. Platforms like Roblox and Fortnite have become identity platforms as much as entertainment ones—where what you wear, what you've built, and who you know define your digital self.

The emergence of AI agents adds a new dimension. When agents act on behalf of humans, identity extends to delegation: which agents represent you, what permissions they have, and how their actions reflect on your identity. The Model Context Protocol and similar frameworks are establishing the technical infrastructure for authenticated agent identity. As Jon Radoff has written, the evolution moves from identity to expression to agency—first we establish who we are online, then we create, then AI lets us project our will through intelligent agents.
