Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If IoT devices connect directly to blockchain networks, then data security and trustworthiness are improved, but system complexity and integration difficulty increase due to differing identity governance mechanisms and varied data formats
Solution Approach 1:
The patent introduces an identity and data management system as an intermediary layer between IoT devices and blockchain networks. This intermediary handles identity verification, data validation, and format standardization, allowing IoT devices to connect to blockchain without direct integration complexity. The intermediary translates varied IoT data formats into standardized blockchain-compatible formats while maintaining security through decentralized identity verification.
2Reliability
If decentralized identity verification is implemented for all IoT devices, then data trustworthiness is improved, but processing time and computational overhead increase
Solution Approach 1:
The patent implements preliminary identity verification and data validation before data is submitted to the blockchain. The identity and data management system performs decentralized identity verification in advance, establishing trusted relationships between IoT devices and the system. This preliminary action ensures data trustworthiness while reducing processing time during actual data submission, as the verification framework is already in place.
3Reliability
If all IoT device data is stored in the blockchain ledger, then data immutability and security are improved, but storage efficiency and network performance deteriorate due to varied data formats and duplicates
Solution Approach 1:
The patent performs preliminary data processing including deduplication and format standardization before data is stored in the blockchain ledger. The identity and data management system identifies and removes duplicate data entries, validates data formats, and structures data according to predefined templates. This preliminary processing ensures that only unique, standardized data is stored in the blockchain, maintaining data immutability while improving storage efficiency and network performance.

AI summary
Examples described herein relate to a blockchain Internet-of-Things (IoT) system. The blockchain IoT system include a blockchain IoT device that generates event data and attests the event data using a decentralized identity provisioned to the blockchain IoT device. The blockchain IoT system further includes a blockchain network coupled to the blockchain IoT device via a network. The blockchain network includes a blockchain IoT management sub-system to receive the event data from the blockchain IoT device, verify the decentralized identity associated with the blockchain IoT device, and upon successful verification of the decentralized identity, process the event data. The blockchain network also includes a blockchain ledger sub-system to verify the processed event data and, upon successful verification of the processed event data, store the processed event data in a distributed ledger.
