Data Sharing Specification

Block Aero data permissions are based on a combination of organization type, org-asset relationship, transaction role, data block type, and data block parameters as configured in the Hyperledger Fabric chain-code and smart contracts of the Aviation Blockchain Network. The business logic of these rules are presented in a permission matrix and as defined in the Block Aero Data Sharing Specification.

Authorized users with the required permissions can upload, download, view and edit data on the blockchain network.
