Keyoxide

Keyoxide is free, open-source software for building and verifying decentralized online identities. A Keyoxide profile is a collection of identity claims, each a link to an account you control on a third-party service (a code forge, a social account, a domain, a Nostr key), bundled into a cryptographically secured document. Anyone can verify the claims against your signing key, proving that the same person controls all of those accounts, without trusting Keyoxide itself or any central registry.

How it replaces Keybase

Keyoxide is often adopted as a self-hostable, no-lock-in alternative to the now-acquired Keybase. Because the proofs live in your own signed profile rather than on a company's servers, there is nothing to be bought, shut down, or quietly changed. This aligns directly with the sovereign Bitcoiner's preference for verifiable, censorship-resistant tooling over platform-dependent trust.

The Ariadne specification

Keyoxide is one implementation of the open Ariadne Spec, a community-governed standard for decentralized identity that no single entity can dominate. Profiles can be anchored to an OpenPGP key or, more recently, to an Ariadne Signature Profile that uses JSON Web Signatures instead, lowering the barrier for users who do not want to manage PGP keys directly.

Keyoxide pairs naturally with PGP / GPG for the signing layer and complements the broader goals of Self-Sovereign Identity.
