Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
IoT devices with limited computing capabilities face challenges in establishing identity and trustworthiness within blockchain networks, as existing solutions are inadequate for processing machine-to-machine transactions and registry management.
Innovation Solution
Integration of an immutable device identity, such as a physical unclonable function, into the blockchain network's infrastructure, enabling pass-through trust services for registration, ledger maintenance, and transaction processing, with a delineate node providing specialized services to support lower capability devices.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IoT devices with limited computing capabilities attempt to establish identity and trustworthiness within blockchain networks using existing solutions, then the devices can participate in the network, but the processing efficiency and transaction management become inadequate
Solution Approach 1:
The patent introduces a delineate node as an intermediary that provides pass-through services for IoT devices. The delineate node receives transactions from low-capability devices, processes them, and submits them to the blockchain network on behalf of the devices. This mediator approach allows IoT devices to participate in blockchain transactions without needing to perform complex cryptographic operations locally, thereby improving processing efficiency while maintaining reliability of identity establishment through the device's immutable identity.
2Ease of operation
If IoT devices perform full blockchain node operations, then they can maintain autonomy, but the energy consumption and computational load exceed their capabilities
Solution Approach 1:
The patent segments the blockchain node functionality into different components. Full blockchain node operations are separated from basic transaction participation. IoT devices only need to perform lightweight identity verification and transaction initiation, while the delineate node handles resource-intensive operations such as consensus participation, ledger maintenance, and complex cryptographic operations. This segmentation enables devices to participate autonomously in essential functions without consuming excessive energy.
3Reliability
If immutable device identity is integrated into the blockchain permissioning framework, then trust establishment is improved, but the system complexity increases
Solution Approach 1:
The patent implements preliminary action by pre-provisioning each IoT device with an immutable device identity (such as a physical unclonable function or hardware-based cryptographic key) before the device connects to the blockchain network. This pre-established identity eliminates the need for complex runtime identity verification mechanisms. The device identity is registered in advance with the delineate node, which stores the device's public key and associated permissions. This preliminary setup simplifies the overall system by removing the need for complex identity management protocols during operation, while maintaining high trust establishment through cryptographic proof of device identity.

AI summary
A computer-implemented method for configuring a blockchain network, a computer program product for integrating device identity into a permissioning framework of a blockchain network, and a blockchain network. One embodiment may comprise registering a device at a delineate node of a blockchain network, creating, by a processor of the delineate node based on the registering, a profile for the device; an performing, by the processor of the delineate node, a pass-through service for the device. The registering may include receiving, by a network interface, an immutable device identity from the device.
