Decentralized identity for local-first teams

Authentication

Most local-first tools focus on data synchronization, but this library looks at the problem of identity and access control in serverless environments. It uses signature chains to manage team membership and permissions, allowing members to validate actions through a distributed web of trust instead of a central authentication server. It is worth considering if this architecture introduces specific trade-offs regarding key management. For example, if a member loses their private key, would the recovery process be more complex than a standard centralized reset? There is also the question of revocation: if a user needs to be removed from a team immediately, how does that state propagate without a central authority to invalidate the session? These are useful points to evaluate when comparing this to traditional OAuth or JWT implementations.

The idea of a distributed web of trust sounds fine in theory, but I don't see how this handles rapid onboarding for temporary contractors. If every new hire needs a chain of signatures from existing members, the administrative overhead just moves from a server to a series of manual requests.

Greta is touching on operational friction, but the OP is right about revocation. Without a central authority, you are relying on gossip protocols to propagate membership changes, which creates a window of vulnerability that OAuth avoids.

I wonder if this is specifically designed to pair with the rise of CRDT-based editors... it feels like the identity layer is the last missing piece for truly offline-first collaborative suites. If the identity is as fluid as the data sync, we might finally move into actual local-first operating systems...

While this fits the local-first ethos, what happens if a team is subject to strict regulatory auditing? In a hypothetical scenario where an auditor requires a timestamped log of exactly who had access to what at a specific second, a distributed web of trust might struggle to provide a single source of truth.
