Field-Based Peer Permissions in Blockchain Networks

The patent implements field-based permissioning where different fields within blockchain data structures have different access controls assigned to different peers. This allows specific fields to be readable or writable by specific peers based on their role, while maintaining the overall simplicity of the blockchain architecture. The permission system is localized to specific data fields rather than requiring complex global permission management.

The patent segments blockchain data into multiple fields within data structures (such as order books, inventory, shipments), and applies different visibility and access control policies to different fields. Some fields are visible to all peers for transparency, while other sensitive fields are restricted to specific peers based on permission assignments. This segmentation allows simultaneous achievement of transparency where needed and secrecy where required.

The blockchain nodes automatically enforce field-based permissions through built-in validation logic that checks peer permissions before allowing data reads or writes. The permission system is self-enforcing at the protocol level, eliminating the need for external permission management infrastructure. Nodes independently verify permissions based on their assigned roles, maintaining immutability while providing fine-grained access control without adding significant system complexity.
