Blockchain Random Number Generator for Online Gaming Fairness
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online gaming systems face challenges in ensuring fair gameplay due to the reliance on pseudo-random number generators, which can be compromised if the private seed becomes known, leading to potential unfair advantages for players or the house.
Innovation Solution
An online gaming platform incorporating a blockchain-based random number generator that utilizes multiple variable inputs, including player-supplied and operator-supplied seed values, combined with a public blockchain's blockhash, to produce a verifiably random output, ensuring high randomness and fairness.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a pseudo-random number generator with a private seed is used, then the system can generate random values for gameplay, but the randomness can be compromised if the private seed becomes known
Solution Approach 1:
The random number generation system is segmented into multiple independent components: player-supplied seed, operator-supplied seed, and blockchain-based random values. Each component contributes a separate element to the final random number, ensuring that no single point of failure or compromise can determine the outcome. This segmentation resolves the contradiction by maintaining reliability through distributed randomness while keeping each individual component relatively simple.
Solution Approach 2:
A blockchain-based intermediary is introduced as a trusted third party that provides verifiable random values without requiring the system to store or manage complex private keys. The blockchain acts as an impartial mediator that both players and operators can trust, eliminating the need for complex key management infrastructure while ensuring fairness through cryptographic verification.
2Reliability
If multiple seed values and blockchain inputs are combined, then the degree of randomness and fairness is improved, but the complexity of the random number generation system increases
Solution Approach 1:
Multiple independent random sources (player seed, operator seed, and blockchain random values) are merged through cryptographic hashing to produce a single verifiable random number. This merging approach enhances reliability by combining the entropy from multiple sources, while the use of standard cryptographic functions keeps the implementation complexity manageable and well-understood.
Solution Approach 2:
The system uses universal cryptographic functions (hashing algorithms) that serve multiple purposes: combining random inputs, verifying fairness, and generating the final random number. This multi-functionality approach maintains high randomness and fairness while avoiding the need for complex specialized algorithms, thereby controlling system complexity.
3Reliability
If a blockchain-based random number generator is used, then verifiable fairness is achieved, but the system requires integration with cryptocurrency infrastructure
Solution Approach 1:
The blockchain serves as an intermediary that provides verifiable randomness without requiring the gaming system to directly handle cryptocurrency transactions or conversions. The random number generation is decoupled from currency management, allowing the system to maintain verifiable fairness while remaining adaptable to different currency types through separate conversion layers.
Solution Approach 2:
The cryptocurrency-specific functionality is extracted from the core random number generation process. The blockchain provides random values through its native mechanism, but the gaming system only needs to consume these values, not understand or manage the underlying cryptocurrency infrastructure. This extraction maintains verifiability while enhancing adaptability to different currency systems.
