Permissions and Payments

NUCs and nilAuth 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

To get started with NUCs, see Network API Access.
