Secure Off-Network Data Retrieval by Trusted Blockchain Validators
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current blockchain technology lacks mechanisms to rectify errant or defective network states without compromising its decentralized and immutable nature, leading to issues like theft, fraud, and inability to recover lost private keys.
Innovation Solution
Implement a trusted third party, such as a judicial court, to authorize modifications by adding new blocks to the blockchain that enforce agreements or judicial decisions, ensuring the third party's authority is secure and decentralized.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blockchain maintains strict immutability and decentralization, then security and trustlessness are improved, but ability to rectify erroneous states is worsened
Solution Approach 1:
The patent introduces a judicial court as an intermediary entity that can authorize modifications to blockchain states. The court reviews disputes and issues rulings that, when implemented through trusted verifiers, allow correction of erroneous states while maintaining the underlying blockchain's immutable structure. This mediator resolves the contradiction by providing a trusted third-party mechanism for rectification without compromising the core immutability principle.
2Ease of repair
If blockchain allows modification of existing blocks, then ability to correct errors is improved, but immutability and decentralization are worsened
Solution Approach 1:
The patent segments the blockchain system into two distinct layers: the immutable blockchain structure that maintains historical records, and a separate judicial/verification layer that handles dispute resolution and authorization of corrections. The judicial court operates independently from the blockchain's core ledger, issuing rulings that are then implemented through trusted verifiers. This segmentation allows error correction capabilities to be added without compromising the immutability of the original blockchain data.
3Ease of operation
If centralized authority is introduced to authorize modifications, then ability to enforce judicial decisions is improved, but decentralization is worsened
Solution Approach 1:
The judicial court serves as a decentralized intermediary that operates outside the traditional blockchain governance structure. Rather than creating a centralized authority within the blockchain, the system integrates an external judicial entity that parties can appeal to for dispute resolution. The court's rulings are implemented through a distributed network of trusted verifiers, maintaining decentralization while providing enforceable judicial decisions.
Data Source
AI summary
Methods and systems for carrying out secure retrieval of off-network data are disclosed. A computing system configured for operating as a validator node of a network of nodes operating a decentralized network may be selected to securely retrieve off-network data for the decentralized network responsive to successfully validating a new data block of the decentralized network. The computing system may then retrieve a queue entry from a queue, and determine from the queue entry a data source of the off-network data. The computing system may then retrieve the off-network data from the data source, generate a cryptographic verification that it carried out the retrieval of the off-network data, and store the cryptographic verification in a verification data structure configured for providing authorization for data entries to be included in future data blocks of the decentralized network.
