Solution Overview

Problem

Existing email systems lack cross-platform value transmission capabilities and integration with digital currency systems, leading to inefficiencies and limitations in financial transactions, while blockchain and digital currencies face challenges in legal protection and practical application.

Innovation Solution

An email-based value transfer method and system that utilizes email interaction servers to establish IP connections, query payment receiving addresses through DNS or SMTP protocols, and perform remittances, integrating with a cluster system for flexible and efficient value transfer across platforms.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If conventional email system is used for information transmission, then communication capability is achieved, but value transmission capability is lost

Engineering Contradiction:
Improvevalue transmission capabilityVSAvoidfinancial responsibility
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The email interaction server is extended to perform multiple functions: both traditional email transmission and digital currency value transfer. The server uses existing email protocols (SMTP, DNS) to achieve cross-platform value transmission, making the system universally applicable for both information and financial transactions without requiring separate dedicated systems

Inventive Principle:
Principle #6Universality (Multi-functionality)

2Adaptability or versatility

If blockchain and digital currency are used for value transfer, then anonymity and cross-platform transmission are achieved, but legal protection and supervision are weakened

Engineering Contradiction:
Improvecross-platform transmission capabilityVSAvoidlegal protection
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The email interaction server acts as an intermediary between the sender and receiver, utilizing the established legal framework of email communication. The server mediates the value transfer process by verifying email addresses through DNS/S MTP protocols and maintaining transaction records, thereby providing legal protection and supervision while preserving cross-platform transmission capability

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If unified interface server is used for digital currency services, then value transfer is achieved, but resource waste occurs

Engineering Contradiction:
Improvevalue transfer efficiencyVSAvoidresource waste
Core Design Contradiction:
ProductivityVSLoss of energy

Solution Approach 1:

The patent merges the digital currency value transfer function with the existing email interaction server infrastructure. By combining these functions in a single server system, the patent eliminates the need for separate unified interface servers, reducing resource waste while maintaining efficient value transfer capability through shared hardware and protocol layers

Inventive Principle:
Principle #5Merging (Combining)

AI summary

An email-based value transfer method and value transfer cluster system comprises the steps of: Establishing an IP connection of the e-mail interaction servers between a remitter and a remittee; Obtaining the payment receiving address of the remittee based on the interactive operations of the e-mail interaction servers; Performing the remittance operation according to the payment receiving address. The value transfer method provided by the present invention supports obtaining, registering and transferring value through e-mail interaction servers without the need of going through a unified interface server for digital/electronic currency services anymore. Using a unified interface address, or a digital/electronic address corresponding to the e-mail address for payment receiving enables the remittance/remittance mail server bound to a domain name to realize value transfer safely, efficiently and economically through the e-mail address outside the system.
