DataPortabilityGrantees

The DataPortabilityGrantees contract maintains the authoritative registry of all entities authorized to receive data access permissions within the Vana data portability ecosystem. Each grantee is registered with a unique identifier, owner address, grantee address, and public encryption key, enabling secure end-to-end encrypted data transfers. The contract tracks the complete set of permissions associated with each grantee, providing a comprehensive view of what data access rights have been granted across the network. Registration requires either maintainer privileges or self-registration where the owner and grantee addresses match, preventing unauthorized entity registration.

This contract serves as a critical component of the permission verification system, working in conjunction with DataPortabilityPermissions to maintain referential integrity. It implements role-based access control with specialized roles for permission management, allowing the permissions contract to automatically update grantee-permission associations when new grants are created or existing ones are modified. The contract provides multiple query interfaces to retrieve grantee information by ID or address, enumerate all permissions for a given grantee, and verify grantee existence during permission creation operations. The public key storage enables grantees to publish their encryption keys on-chain, facilitating secure data exchange protocols between data owners and authorized recipients.
