Cross-Network Identity Provisioning via Interoperation Identity Network
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized databases face issues with data redundancy, security, and scalability, particularly in cross-network identity provisioning, where traditional databases fail to provide immutable and tamper-proof storage, leading to inefficiencies and vulnerabilities in data management and access control.
Innovation Solution
Implementing a blockchain-based system that enables cross-network identity provisioning through the creation of an interoperation identity network (IIN) using self-sovereign identity (SSI) networks, smart contracts, and verifiable credentials, allowing for secure, decentralized, and permissioned access control across multiple blockchain networks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized database is used for identity management, then ease of management and control is improved, but security and immutability deteriorate due to vulnerability to tampering and single point of failure
Solution Approach 1:
The centralized database is segmented into a distributed network of blockchain nodes, where identity data is distributed across multiple participants rather than stored in a single location. This segmentation eliminates the single point of failure while maintaining manageable access control through cryptographic protocols and consensus mechanisms.
Solution Approach 2:
A blockchain intermediary layer is introduced between identity providers and verifiers, enabling secure identity management without requiring direct trust between parties. The blockchain acts as a neutral mediator that ensures immutability and transparency while maintaining ease of operation through standardized interfaces.
2Quantity of substance
If a centralized database is used, then data redundancy is minimized with a single storing place, but scalability and cross-network interoperability worsen due to inability to support multiple blockchain networks
Solution Approach 1:
The blockchain identity management system is designed with universal functionality that enables it to serve multiple blockchain networks simultaneously. The identity verification mechanisms are network-agnostic, allowing the same identity credential to be verified across different blockchain ecosystems, thereby achieving cross-network interoperability without duplicating identity data.
Solution Approach 2:
The system transitions from a single-dimension centralized storage model to a multi-dimensional distributed architecture where identity data exists across multiple blockchain networks. This dimensional expansion enables the system to maintain data efficiency while supporting interoperability across diverse blockchain ecosystems through standardized identity protocols.
3Ease of operation
If traditional database access control is used, then ease of operation is maintained, but reliability and trustworthiness deteriorate due to lack of immutable and tamper-proof storage
Solution Approach 1:
Access control policies are established in advance through smart contracts that encode authorization rules immutably on the blockchain. These preliminary actions ensure that access control decisions are made automatically based on pre-defined criteria, eliminating manual intervention while maintaining both ease of operation and high trustworthiness through cryptographic verification.
Solution Approach 2:
The system implements continuous feedback mechanisms where access control decisions are transparently recorded on the blockchain and can be independently verified. This feedback loop ensures that the system maintains trustworthiness by providing auditable proof of access control operations while preserving ease of operation through automated enforcement of policies.

AI summary
An example operation includes one or more of connecting, by an identity provisioning node, a blockchain one to a blockchain two, creating, by an identity provisioning node, an interoperation identity network (IIN) for the blockchain one and for the blockchain two as an instance of a self-sovereign identity (SSI) network, executing a smart contract to: invoke an IIN access control policy, map attributes and permissions of the blockchain one to attributes and permissions of the blockchain two based on the IIN access control policy, and generate a valid verifiable credential (VC) of the IIN in the blockchain one and in the blockchain two based on the mapped attributes and the permissions.
