Permissions and Payments

NUCs provide the access control layer of the Blind Computer, allowing data owners to define, delegate, and revoke permissions over their data.

NUC

Built on an extension of UCAN, the NUC framework supports user-originated, cryptographically signed policies for read, write, and compute access. Permissions are enforced at the system level, without relying on centralized coordination. Two versions of the NUC library are available:

• TypeScript library for web and Node.js environments: GitHub repository and NPM package
• Python library for server-side applications: GitHub repository and PyPI package

Credits

Regarding payments, nilCC uses a NIL based credit system whereas nilAI - as a product built on top of nilCC - has a Stripe integration. The credits are used in a pay-as-you-go fashion and can be topped up from the respective management portals for these modules. nilAI has a free tier available. Visit the Developer Portal to explore these options.
