Solution Overview

Problem

Existing blockchain transaction processes are time-consuming and frustrating due to the need for repeated user interaction, especially with trusted merchants, and lack a method for streamlined transactions without compromising security.

Innovation Solution

A system and method for automatically initiating blockchain transactions with pre-approved recipients by validating recipient identifiers and transaction amounts, using locally stored data or smart contracts, and digitally signing transactions with a private key, reducing user interaction to a single confirmation.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If standard blockchain transaction process is used with QR code scanning, then security is maintained, but transaction speed and user convenience deteriorate

Engineering Contradiction:

Improvetransaction securityVSAvoidtransaction time

Core Design Contradiction:

ReliabilityVSLoss of time

Solution Approach 1:

The system performs preliminary actions by pre-registering recipient addresses and transaction parameters before the actual transaction occurs. Users can pre-approve recipients and set transaction limits in advance, so that when a transaction is needed, the system can quickly execute it without requiring full authentication steps each time. This resolves the contradiction by preparing security credentials beforehand, enabling fast execution while maintaining security verification.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system enables self-service by allowing users to configure their own transaction parameters, pre-approve recipients, and set automatic transaction rules without requiring manual intervention for each transaction. The system automatically matches transaction requests against pre-configured rules and executes approved transactions, reducing the need for repeated user actions while maintaining security through pre-established authorization.

Inventive Principle:

Principle #25Self-service

2Reliability

If repeated user interaction is required for each transaction, then security is maintained, but ease of operation deteriorates

Engineering Contradiction:

Improvetransaction securityVSAvoiduser convenience

Core Design Contradiction:

ReliabilityVSEase of operation

Solution Approach 1:

Users perform security-related actions in advance by pre-approving recipients and setting transaction parameters. The system stores these preliminary authorizations and automatically applies them when transaction requests match the pre-configured criteria, eliminating the need for repeated security confirmations while maintaining the security model.

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system allows users to set up automatic transaction rules and pre-approvals that serve themselves without requiring continuous user interaction. Once configured, the system autonomously handles transaction authorization by matching requests against pre-established rules, providing both security and convenience.

Inventive Principle:

Principle #25Self-service

3Ease of operation

If automatic transaction initiation is implemented, then ease of operation improves, but device complexity increases

Engineering Contradiction:

Improveuser convenienceVSAvoidsystem complexity

Core Design Contradiction:

Ease of operationVSDevice complexity

Solution Approach 1:

The system reduces operational complexity by moving complex logic to the preliminary configuration phase. Users set up transaction rules, recipient approvals, and parameter constraints in advance, allowing the system to automatically execute transactions by simple rule matching without requiring complex real-time decision-making or user intervention.

Inventive Principle:

Principle #10Preliminary action

4Productivity

If pre-approved recipients are used, then productivity improves, but loss of information increases

Engineering Contradiction:

Improvetransaction speedVSAvoidtransaction detail verification

Core Design Contradiction:

ProductivityVSLoss of information

Solution Approach 1:

Transaction parameters such as recipient addresses, amount limits, and authorization levels are determined in advance and stored as pre-approvals. This allows rapid transaction execution by simply matching the current transaction against pre-configured parameters, maintaining productivity while ensuring that critical transaction details were previously verified and approved.

Inventive Principle:

Principle #10Preliminary action

AI summary

A method for automatic initiation of a blockchain transaction with a pre-approved recipient includes: receiving at least a recipient identifier and a transaction amount; performing a validation process to validate that (i) the recipient identifier is pre-approved by a user of the computing device for blockchain transactions, and (ii) the transaction amount is beneath a predetermined amount limit for blockchain transactions; generating a new blockchain transaction including at least the recipient identifier, the transaction amount, and one or more source addresses; digitally signing the new blockchain transaction using a private key of a first cryptographic key pair stored in a memory of the computing device; and transmitting the digitally signed new blockchain transaction to a blockchain node in a blockchain network.
