Blockchain Identity Management Using SSI Verifiable Credentials
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Centralized data platforms face challenges in managing identities and credentials across multiple networks, lacking decentralized and secure solutions for identity verification and data storage.
Innovation Solution
Implementing a blockchain network with self-sovereign identity (SSI) that assigns unique decentralized identifiers (DIDs) to entities, enabling them to create and manage verifiable credentials (VCs) for signing transactions and maintaining identity records without relying on central authorities, using a decentralized database with consensus protocols for secure and tamper-proof storage.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a centralized platform is used to store and manage identity data, then ease of management and control is improved, but security and decentralization are worsened
Solution Approach 1:
The patent segments identity management into two parts: a centralized platform for ease of management and a decentralized blockchain network for security. The centralized platform manages identity data while the blockchain stores verifiable credentials, combining the advantages of both centralized control and decentralized security.
Solution Approach 2:
The patent introduces verifiable credentials as an intermediary between the centralized platform and the blockchain network. These credentials enable secure verification of identity information without requiring direct access to the centralized database, thus maintaining security while enabling verification.
2Loss of information
If a centralized platform stores all identity data in a single location, then data redundancy is minimized, but accessibility and interoperability across multiple networks are worsened
Solution Approach 1:
The patent creates verifiable credential copies that can be shared across multiple blockchain networks. Instead of storing all data centrally, the system generates portable credential copies that maintain data integrity while enabling interoperability across different networks and platforms.
Solution Approach 2:
The verifiable credentials are designed to be universally applicable across multiple blockchain networks and use cases. A single credential can serve multiple purposes and be verified on different networks, enhancing interoperability without requiring data duplication in multiple centralized locations.
3Reliability
If proprietary identity management systems are implemented on different blockchains, then network-specific security is improved, but portability and interoperability of identities are worsened
Solution Approach 1:
The patent implements universal verifiable credentials that work across multiple blockchain networks while maintaining each network's security requirements. The same credential format and verification mechanism can be used on different networks, enabling portability without compromising network-specific security protocols.

AI summary
An example operation may include one or more of receiving a request for storage at a blockchain network, attaching, via a blockchain node, a verifiable credential created by a self-sovereign identity (SSI) network to a blockchain transaction associated with the request, where the verifiable credential includes a claim of the blockchain node and a proof of the SSI network that created the verifiable credential, transmitting the blockchain transaction and the attached verifiable credential to one or more other blockchain nodes, and storing the blockchain transaction and the attached verifiable credential via a data block on the blockchain.
