Abstract
One embodiment disclosed relates to a system for managing data for logistics, sourcing and/or production. The system includes: a private blockchain maintained by a first network of nodes; a trusted public blockchain maintained by a second network of nodes; a private agent system; and a bridge system connected to both the private blockchain and the public blockchain. The private agent system operates to extract blocks of metadata from the private blockchain and utilize a hash tree structure to generate a first root hash value from the blocks of metadata. The bridge system operates to verify the first root hash value and store the first root hash value as a notarized data certificate in the trusted public blockchain. Another embodiment disclosed relates to a method for data certificate notarization utilizing a bridging system from a private blockchain to a trusted public blockchain. Other embodiments and features are also disclosed.
