It seems you have a question related to a new database-less passkey plugin for Better Auth. This plugin is designed to facilitate blockchain-as-database deployments by utilizing cookie-based challenges, allowing for stored passkey data in external systems like blockchain or IPFS, while eliminating the need for traditional databases.

Key Features:

  1. Cookie-Based Challenges: Supports short-lived, ephemeral data storage without a database.
  2. Custom Storage: Enables storage of passkey data in blockchain or other external systems.
  3. Asynchronous Blockchain Writes: Uses hooks for non-blocking operations.

Security Considerations:

  • Accepts replay risk if counter verification is disabled, which allows for a fully database-less authentication flow but may open up potential replay attacks.

Example Configuration:

passkey({
  storage: 'custom',           // Use blockchain or external storage
  challengeStrategy: 'cookie', // No database for challenges
  verifyCounter: false,        // Accept replay risk
  customStorage: blockchainAdapter,
  hooks: { afterCreatePasskey: writeToBlockchain }
});

This configuration prioritizes a fully stateless architecture, presenting a secure yet flexible model for user authentication without reliance on traditional databases.

If you're interested in implementing or discussing this plugin further, or have any specific questions about it, feel free to ask! What features are you most excited about exploring with this new plugin?
