Taostats has introduced a new authentication system designed to bring onchain identity into standard application login flows.
Called the Bittensor Auth Gateway, the tool allows developers to implement OAuth2 and OpenID Connect (OIDC) login using a user’s wallet, with permissions derived directly from their onchain state.
Introducing Bittensor Auth Gateway.

Sign in with Bittensor. It's a standard OAuth2/OIDC login with a key difference - identity is backed by the chain.
Your wallet is your identity and your on-chain state is your permissions.

Bridging Wallets and Traditional Auth
Bittensor already tracks a range of identity primitives onchain, including miners, validators, subnet ownership, and stake levels. However, most applications built around the ecosystem have relied on custom authentication systems, often requiring manual allowlists and off-chain user management.
The Auth Gateway is designed to replace those systems by linking authentication directly to the chain.
Users sign in with their wallet, after which the system verifies their onchain state and issues a JSON Web Token (JWT) containing relevant attributes such as hotkey, coldkey, subnet participation, and stake level. Applications can then grant or restrict access based on those parameters.
Chain State as Source of Truth
The system removes the need for maintaining separate user databases or manually updating permissions.
Access is determined entirely by onchain activity. When a user registers, gains stake, or acquires a role, those changes are reflected automatically. If a validator is deregistered or a role is removed, access can be revoked without manual intervention.
This model shifts identity management from application-level logic to protocol-level state.
Built for Developers and Existing Tooling
The gateway is designed to integrate with existing authentication infrastructure. It follows standard OAuth2 and OIDC patterns, allowing developers to use familiar libraries without requiring a custom SDK.
Taostats has open-sourced the project under an MIT license and also provides a hosted version for teams that prefer not to self-deploy.
Enabling New Application Patterns
This new approach enables a range of use cases tied directly to onchain identity, including validator dashboards that automatically revoke access upon deregistration, token-gated content based on stake thresholds, and subnet-specific portals that verify ownership without manual checks.
It also supports device-based login flows, allowing command-line tools and headless environments to authenticate without a browser.
Moving forward, developers across the Bittensor ecosystem will be able to rely on a shared, chain-native identity layer instead of rebuilding authentication from scratch.
That shift lowers friction for builders while introducing a standard way for applications to interpret onchain roles and permissions, making it easier to develop tools that operate natively within the network.
