Application: Methods, architectures, apparatuses and systems directed to blockchain-enabled model storage, sharing and deployment for supporting distrubuted learning (Patent ID: US20240045851A1)

The patent filed by InterDigital Inc. focuses on blockchain-enabled model storage, sharing, and deployment to support federated learning. The method involves receiving a blockchain storage request related to a distributed learning task, identifying suitable blockchains based on the request, determining blockchain-related instructions, and transmitting these instructions to distributed participant nodes. The patent also describes a transmit/receive unit with circuitry to perform these functions, including receiving the storage request, obtaining blockchain information, determining instructions, and transmitting them to participant nodes.

The patent claims detail the method and transmit/receive unit's functions, such as receiving blockchain storage requests, identifying suitable blockchains, determining instructions, and transmitting them to participant nodes. The claims also cover aspects like determining the blockchain storage solution based on the request, obtaining blockchain information from nodes, creating new blockchains if necessary, and implementing the storage solution. Additionally, the claims address scenarios where the storage request is initiated from an application, information associated with participant nodes and model updates, and different versions of local model updates stored in separate blockchains. Overall, the patent and its claims outline a comprehensive system for blockchain-enabled storage, sharing, and deployment of learning models to support federated learning processes.
