Blockchain Game Item Transaction System for Secure Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In online MMORPGs, game item transactions lack security and transparency due to reliance on central databases, making them vulnerable to hacking and inconvenient as they often involve in-game currency rather than real money, leading to risks in personal transactions.
Innovation Solution
A game item transaction system utilizing a blockchain to record and validate transaction information, ensuring secure and transparent ownership changes and payments by broadcasting transaction data across a network, with a mediation server and financial server handling user IDs and real-name information for secure transactions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a central database is used to store transaction information, then the system is easier to operate and manage, but the security and transparency of transactions deteriorate due to vulnerability to hacking and lack of public verification
Solution Approach 1:
The patent segments the centralized database into a distributed blockchain network where transaction information is divided across multiple nodes. Each node maintains a copy of the ledger, eliminating the single point of failure and enabling both ease of operation through standardized protocols and enhanced security through decentralization.
Solution Approach 2:
The patent introduces a mediator layer consisting of consensus mechanisms and smart contracts that facilitate transactions between parties without requiring a centralized authority. This intermediary structure maintains operational simplicity while ensuring security through cryptographic verification and distributed consensus.
2Device complexity
If transaction details are stored only in a private database, then the system structure remains simple, but the publicness and verifiability of transactions deteriorate
Solution Approach 1:
The patent creates a universal blockchain ledger that serves multiple functions simultaneously: it maintains a simple data structure for efficiency, provides public transparency through distributed access, and enables verifiable transaction records. The same ledger structure supports both private transaction confidentiality and public verification capabilities.
3Device complexity
If game item transactions use game money instead of real money, then the transaction system remains simple, but the reliability and security of transactions deteriorate due to lack of real-value accountability
Solution Approach 1:
The patent changes the fundamental parameter of transaction value from virtual game money to real currency backed by blockchain technology. This parameter change maintains system simplicity through automated smart contract execution while dramatically improving reliability by anchoring transactions in real-world value with cryptographic security and immutable ledgers.
