Blockchain Ticketing System for Electronic Gaming Machines
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional coinless ticketing systems in electronic gaming machines rely on a client/server architecture, which poses technical challenges such as system reliability and security issues like hacking and regulatory compliance.
Innovation Solution
A blockchain-based ticketing system is introduced, where electronic gaming machines participate in a blockchain network, utilizing local and system blockchains to create and manage ticketing transactions, thereby decentralizing the ticketing process and enhancing security and transparency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If a client/server architecture is used for ticketing systems, then ease of operation and centralized control are improved, but system reliability and security deteriorate due to single point of failure and hacking risks
Solution Approach 1:
The patent divides the centralized ticketing system into distributed nodes across a blockchain network. Each node maintains its own copy of the ticketing data and can independently validate transactions, eliminating the single point of failure in client/server architectures while maintaining operational ease through standardized protocols.
Solution Approach 2:
The blockchain acts as an intermediary layer between ticketing operations and storage. Instead of direct client-server communication, transactions are broadcast to the network, validated by consensus mechanisms, and recorded immutably, providing both decentralization and reliability.
2Ease of operation
If a client/server architecture is used for ticketing systems, then ease of operation and centralized control are improved, but security deteriorates due to hacking risks and regulatory compliance issues
Solution Approach 1:
The system performs preliminary validation and consensus checking before finalizing any ticketing transaction. Multiple nodes verify transaction legitimacy in advance, preventing malicious actions before they can compromise system security, while maintaining ease of operation through automated validation rules.
Solution Approach 2:
The blockchain consensus mechanism serves as an intermediary security layer that mediates between ticketing operations and system integrity. Transactions must pass through multiple validation stages involving different nodes, making hacking attempts detectable and preventable while preserving operational simplicity.
3Reliability
If a blockchain-based ticketing system is implemented, then system reliability and security are improved through decentralization, but device complexity increases
Solution Approach 1:
The patent implements a universal blockchain protocol that handles multiple ticketing operations (issuance, transfer, redemption, validation) through a single standardized framework. This multi-functionality reduces the need for separate complex systems while maintaining high reliability through consistent application of the same proven protocol across all operations.
4Object-affected harmful factors
If a blockchain-based ticketing system is implemented, then security and transparency are improved, but loss of time increases due to distributed consensus processing
Solution Approach 1:
The system implements partial consensus mechanisms where not all nodes must validate every transaction fully. Instead, a sufficient subset of nodes performs validation to achieve the required security level, reducing processing time while maintaining adequate security and transparency through selective verification.

AI summary
A blockchain system for providing ticketing within a blockchain network of participating electronic devices includes an electronic gaming machine (EGM) configured to participate in the blockchain network. The EGM a memory storing a local blockchain and a system blockchain. The EGM also includes at least one processor configured to execute instructions which, when executed, cause the at least one processor to identify a first ticket creation blockchain transaction in the local blockchain from a ticket creation device of the first plurality of electronic gaming devices, the first ticket creation blockchain transaction including at least a ticket value and a ticket identifier (ID), create a system ticket creation blockchain transaction including at least the ticket value and the ticket ID, and broadcast the system ticket creation blockchain transaction to the system blockchain.
