Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing data confidence fabrics face challenges in efficiently distributing identifiers to applications and clients, which affects the trustworthiness and reliability of data usage.
Innovation Solution
A data confidence fabric network (DCF) is implemented with a distributed ledger system that includes a global topic for trust providers, allowing applications to query and obtain universal identifiers for specific trust providers, enabling automated and efficient distribution of trust-related annotations and transactions.

Engineering Contradiction Analysis
1Extent of automation
If manual distribution of identifiers is used in data confidence fabrics, then control and security are maintained, but efficiency and automation are reduced
Solution Approach 1:
A blockchain-based intermediary system is introduced to mediate the distribution of identifiers between trust providers and data consumers. The blockchain ledger acts as a neutral mediator that automatically manages identifier issuance, validation, and distribution without requiring manual intervention, thereby achieving automation while maintaining security through cryptographic verification.
Solution Approach 2:
The system enables self-service by allowing trust providers to autonomously register their identifiers on the blockchain and allowing data consumers to automatically retrieve and validate identifiers through smart contracts. This self-service mechanism eliminates manual distribution processes while maintaining system security through automated verification protocols.
2Reliability
If centralized identifier distribution is used, then control is maintained, but trust and decentralization are reduced
Solution Approach 1:
The identifier distribution system is segmented into independent blockchain nodes that operate autonomously but maintain consistency through consensus mechanisms. Each node can independently validate and distribute identifiers, enabling decentralization while maintaining reliability through distributed verification. This segmentation allows the system to be both decentralized and trustworthy simultaneously.
Solution Approach 2:
The blockchain-based identifier distribution system serves multiple functions: it acts as a decentralized registry, a validation mechanism, a distribution channel, and a trust verification system all in one. This universal system provides both decentralization and reliability by combining multiple functions into a single trusted infrastructure that can adapt to various data confidence fabric scenarios.
3Reliability
If traditional data sharing methods are used, then simplicity is maintained, but data confidence and trust scoring are reduced
Solution Approach 1:
Trust scores and confidence metrics are calculated and recorded in advance on the blockchain before data sharing occurs. Identifiers are pre-registered and validated on the blockchain ledger prior to being distributed to data consumers. This preliminary action ensures data confidence is established beforehand, simplifying the actual data sharing process while maintaining high trust levels through pre-validated identifiers.
Solution Approach 2:
The system implements feedback mechanisms where trust scores are continuously updated and recorded on the blockchain based on data quality, provider reliability, and usage patterns. This feedback loop provides real-time confidence scoring that enhances data reliability while the automated blockchain-based tracking simplifies the complexity of monitoring and verifying data trustworthiness across the network.

AI summary
A distributed ledger is configured with a global topic whose identifier is publicized and well known. The global topic stores information about trust providers including topic identifiers and smart contract identifiers. Requestors can query the global topic to retrieve the information of specific trust providers. Once the information of the specific trust providers is known, the requestors can publish or write annotations and transactions to the distributed ledger. By associating the entries in the global topic with timestamps, requestors can reconfigure themselves automatically with updated trust provider information whenever a write to the distributed ledger fails.
