Blockchain Transaction Guide Server for Digital Currency
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing digital virtual currency transaction systems require both parties to have electronic wallets and recognize each other's public addresses, making consumer-to-consumer transactions cumbersome and prone to errors, especially with long and complex public addresses.
Innovation Solution
A transaction system and method that uses a block chain-based digital virtual currency transaction guide server to generate and transmit a receiver transaction selecting URL, allowing receivers to complete transactions without an electronic wallet and without recognizing public addresses, using a URL-based process that guides users through electronic wallet creation, login, or public address input as needed.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If both parties create electronic wallets and use public addresses for transactions, then digital virtual currency transactions can be performed securely, but the transaction process becomes complex and error-prone due to long public addresses
Solution Approach 1:
The patent introduces a transaction guide server as an intermediary between the giver and receiver. The server generates and manages transaction URLs that replace the need for direct public address interaction. Users simply input their email addresses or phone numbers, and the server handles the complex public address generation and verification, eliminating errors while maintaining security.
Solution Approach 2:
The patent creates a simplified digital representation (transaction URL) that copies the essential function of public addresses without their complexity. The transaction URL encapsulates the receiver's public address information in a user-friendly format that can be easily shared and recognized, reducing errors while preserving the cryptographic security of the original public address system.
2Ease of operation
If QR codes are used for Bitcoin payment, then public addresses can be converted into scannable format, but the transaction process becomes complicated and requires capturing the transaction
Solution Approach 1:
The patent extracts the essential function of QR code scanning (visual recognition of addresses) and separates it from the complex transaction capture process. The transaction guide server directly generates transaction URLs that can be shared through any communication channel, eliminating the need for QR code scanning infrastructure and complex capture processes while maintaining ease of address recognition.
3Ease of operation
If previously provided QR codes are used for multiple transactions, then convenience is improved, but security risk increases due to potential leakage
Solution Approach 1:
The patent implements dynamic transaction URLs that are generated fresh for each transaction and expire after use. Unlike static QR codes that can be reused, each transaction URL is time-limited and single-use, automatically becoming invalid after the transaction is completed or a specified time period elapses. This dynamic approach maintains convenience while eliminating the security risks of code leakage and reuse.
4Reliability
If receivers without electronic wallets are excluded from transactions, then transaction security is maintained, but consumer-to-consumer transactions become limited
Solution Approach 1:
The patent performs preliminary wallet creation actions on behalf of users who don't have electronic wallets. When a receiver without a wallet initiates a transaction, the transaction guide server automatically creates the necessary electronic wallet and public address in the background, then provides the user with a simple transaction URL. This preliminary action enables secure transactions for all users regardless of their prior wallet status.

AI summary
The present invention relates to a digital virtual currency transaction system and method which enable a receiver to make digital virtual currency transactions having a block chain regardless of whether an electronic wallet has been opened, and which have a block chain between concerned parties to guide the concerned parties to be able to conveniently make URL-based transactions without recognizing a public address comprised of 32 bytes or more for every digital virtual currency transaction having a block chain between concerned parties. Provided are a system and a method using same, the system comprising: a block chain-based digital virtual currency transaction guide server (100); a giver terminal (200) which is loaded with a giver-side block chain-based digital virtual currency transaction app (210), generates a giver transaction request signal; and a receiver terminal 300 which clicks the receiver transaction selecting URL (A).
