Blockchain Address Identity Mapping With Guardian Authentication
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The inability to know the true identity of the owner of a blockchain address prevents wider adoption in regulated environments and leads to issues such as asset loss, theft, and inheritance complications due to the reliance on private keys for identification.
Innovation Solution
Embedding owner identification information within the blockchain address, optionally encrypted, and using trusted Guardians for authentication to verify identity and facilitate transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain addresses are used for identifying users in permissionless networks, then trustless peer-to-peer capabilities are maintained, but true identity verification becomes impossible
Solution Approach 1:
The patent introduces a Guardian as an intermediary entity that bridges the trustless blockchain system and the need for identity verification. The Guardian maintains a mapping between blockchain addresses and real-world identities, allowing verification without requiring a centralized access control layer. This resolves the contradiction by enabling identity verification through a decentralized intermediary rather than a centralized authority.
Solution Approach 2:
The system segments the identity verification function from the blockchain transaction mechanism. Blockchain addresses continue to function for peer-to-peer transactions, while the Guardian separately maintains and manages the mapping to real identities. This segmentation allows the blockchain to remain trustless while enabling identity verification through a separate, specialized component.
2Ease of operation
If private keys are used for user identification, then peer-to-peer transaction capabilities are enabled, but security vulnerabilities increase due to reliance on single key control
Solution Approach 1:
The patent applies local quality by differentiating between two types of keys: blockchain addresses (public keys) for transaction execution and private keys for authentication. The Guardian additionally maintains a second layer of authentication using its own private key to verify the mapping between addresses and identities. This multi-layer approach enhances security by distributing trust across multiple keys rather than relying on a single private key.
Solution Approach 2:
The Guardian performs preliminary authentication by verifying the mapping between blockchain addresses and real identities before transactions occur. This preliminary action ensures that the correct identity is associated with the address beforehand, preventing security issues during transaction execution and eliminating the need for complex real-time verification.
3Adaptability or versatility
If no access control layer is implemented, then permissionless transactions are enabled, but regulated environments cannot verify user identities
Solution Approach 1:
The Guardian serves multiple functions: it maintains the mapping between blockchain addresses and real identities for regulatory compliance, provides authentication for transactions, and enables identity verification without requiring a centralized access control layer. This multi-functionality allows the system to adapt to regulated environments while maintaining the permissionless nature of the blockchain.
4Ease of manufacture
If blockchain addresses without embedded identification are used, then system simplicity is maintained, but inheritance and dispute resolution become problematic
Solution Approach 1:
The Guardian provides feedback mechanisms for asset recovery and dispute resolution by verifying the mapping between blockchain addresses and real identities. When inheritance or dispute issues arise, the Guardian can authenticate the rightful owner and facilitate asset recovery. This feedback loop enables reliable asset recovery while maintaining system simplicity, as the Guardian operates as a decentralized service rather than requiring complex embedded identification in addresses.
Data Source
AI summary
The invention is directed to computer-based method and a computer system for generating a blockchain address. The method comprises receiving a request for a new blockchain address for a user, the request including a public key, which has an associated private key, and identification information for the user, and generating the address based on a combination of the public key and the identification information.
