Blockchain Gaming System Smart Contract Security
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Lotteries and other games of chance face significant challenges in securing their infrastructure against internal and external malicious threats, such as cyberattacks and fraud, due to the complexity and cost of implementing sophisticated security measures, which often prove futile against growing sophisticated threats.
Innovation Solution
The implementation of a distributed ledger gaming system using smart contracts to control and secure games of chance, allowing for secure and verifiable operations by recording smart contract code in a blockchain, enabling secure ticket issuance, player interactions, and payout management without the need for traditional reseller terminals and dedicated communication links.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If sophisticated security techniques are implemented to protect lottery infrastructure, then security against malicious threats is improved, but operational costs and system complexity increase significantly
Solution Approach 1:
The patent replaces the mechanical/physical security system (dedicated networks, terminal hardware, paper ticket stock) with a cryptographic system based on blockchain technology. Smart contracts encode game rules and security protocols in immutable code, eliminating the need for complex physical infrastructure while maintaining or enhancing security against both external cyberattacks and internal fraud.
Solution Approach 2:
The blockchain platform serves multiple functions simultaneously: it acts as a distributed ledger for ticket sales, a secure random number generator for draw results, a payment processing system for payouts, and an audit trail for regulatory compliance. This multi-functionality reduces overall system complexity compared to having separate systems for each function.
2Adaptability or versatility
If dedicated infrastructure is purchased and maintained for each lottery operation, then operational independence is improved, but costs and resource requirements increase
Solution Approach 1:
The patent merges multiple lottery operations onto a single shared blockchain infrastructure. Different lotteries can operate independently through separate smart contracts while sharing the underlying network, consensus mechanism, and security protocols. This eliminates redundant infrastructure costs while maintaining operational independence through code-level isolation.
Solution Approach 2:
The blockchain system provides self-service capabilities where each lottery operation manages its own configuration, ticket issuance, and payout distribution through automated smart contracts. The system autonomously handles security, randomness generation, and transaction validation without requiring dedicated human teams for each lottery, reducing operational costs while maintaining independence.
3Ease of operation
If traditional lottery infrastructure with reseller terminals is used, then ticket distribution control is improved, but security vulnerabilities and maintenance requirements increase
Solution Approach 1:
The patent introduces the blockchain network as an intermediary layer between ticket purchasers and the lottery operator. Instead of direct connections through vulnerable terminal systems, all ticket sales, draw results, and payouts are mediated through cryptographic transactions on the blockchain. This eliminates security vulnerabilities in traditional terminal systems while maintaining distribution control through smart contract logic.

AI summary
A system is provided for securely issuing a ticket for a draw of a game via smart contracts of a blockchain. The system records in the blockchain a game smart contract. The game smart contract records a draw smart contract for issuing tickets for a draw of the game. The game smart contract receives a game place order message indicating placement of an order for a ticket for the draw of the game. The game smart contract sends to the draw smart contract a draw place order message indicating the placement of the order for the ticket for the draw of the game. The game smart contact receives from the draw smart contract a confirmation that the ticket for the draw of the game has been issued. The game smart contract coordinates generation of winning drawlines and directs the draw smart contract to identify winning tickets.
