Blockchain Transaction Auto-Signing Through Predefined Rules
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The time-consuming and complex nature of digital signing processes in blockchain transactions hinders the adoption and scalability of blockchain technology, particularly due to resource-intensive cryptographic computations and the need for technical expertise, creating barriers for less tech-savvy users.
Innovation Solution
An auto-signing wallet that stores predefined rules and automatically decides whether to sign, reject, or submit blockchain transactions based on user-defined conditions, using blockchain platform-agnostic rules without requiring server interaction or external validation, allowing for user-friendly and efficient transaction management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If digital signing processes are performed manually with cryptographic computations, then security and authenticity are ensured, but the process becomes time-consuming and complex
Solution Approach 1:
The system pre-defines multiple transaction models with associated signing rules before actual transactions occur. When a transaction arrives, the system matches it against pre-configured models and applies predetermined signing actions, eliminating the need for real-time cryptographic decision-making while maintaining security.
Solution Approach 2:
The auto-signing system enables transactions to be signed automatically without requiring manual user intervention for each transaction. The system self-manages the signing process by evaluating transactions against predefined rules and executing appropriate signing actions, reducing time loss while maintaining security through rule-based validation.
2Reliability
If cryptographic computations are performed for each transaction, then digital signatures are secure, but resource consumption increases
Solution Approach 1:
Signing rules and validation criteria are configured in advance rather than computed in real-time. The system prepares transaction models and associated signing parameters beforehand, so that during actual transaction processing, minimal computational resources are needed to match transactions against pre-computed models rather than performing full cryptographic validation for each transaction.
3Ease of operation
If manual signing processes are used, then user control is maintained, but the system becomes complex and difficult to operate
Solution Approach 1:
The system automatically manages the complexity of transaction evaluation and signing decision-making through self-service automation. Users simply define high-level signing rules and preferences, while the system handles the complex task of evaluating each transaction against multiple criteria and executing appropriate signing actions, making the system easy to operate despite its internal complexity.
Solution Approach 2:
The system provides feedback mechanisms that allow users to review and adjust signing rules based on transaction patterns. This feedback loop enables users to maintain control over the signing process while the system handles the computational complexity, improving ease of operation through intuitive rule management.
4Productivity
If automatic signing is implemented without predefined rules, then transaction throughput increases, but security and user control may be compromised
Solution Approach 1:
The system implements automatic signing with enhanced security by pre-defining multiple transaction models with specific signing rules and criteria before processing transactions. This preliminary configuration ensures that automated signing maintains security through rule-based validation while achieving high throughput through automated evaluation and execution.

AI summary
A user device is disclosed. The user device comprises means for storing at least one private key of a user of the user device and predefined auto-signing rules; receiving a blockchain transaction; decoding the blockchain transaction according to a blockchain transaction model to extract attributes of the blockchain transaction; submitting the decoded blockchain transaction to an auto-signing rules engine; evaluating the blockchain transaction by the auto-signing rules engine based on the auto-signing rules by comparing the attributes of the blockchain transaction and conditions of the auto-signing rules; and automatically deciding based on the evaluation and the auto-signing rules whether to automatically sign the blockchain transaction on behalf of the user using the at least one private key, to reject the blockchain transaction on behalf of the user, or to submit the blockchain transaction to the user to let the user decide on signing the blockchain transaction.
