Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing online gaming systems face issues with collusion, lack of verifiability, and fairness in token-based games, particularly in token distribution and privacy, due to central server reliance, which can lead to trust concerns among players.
Innovation Solution
A client-server-based system that involves all players in critical steps of token-based games, using cryptographic protocols and commitments to ensure collusion resistance, verifiability, and provable fairness, allowing players to self-enforce integrity and fairness through shared key management and decentralized processes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If a central server uses RNG to shuffle and distribute tokens, then the game can be hosted efficiently, but players cannot verify fairness and trust issues arise
Solution Approach 1:
The patent introduces cryptographic intermediaries (commitment schemes, zero-knowledge proofs, and verifiable random functions) between the server and players. These cryptographic mechanisms act as mediators that allow the server to perform efficient token distribution while enabling players to independently verify fairness without trusting the server's RNG implementation.
Solution Approach 2:
The patent replaces the mechanical/trust-based RNG system with a cryptographic system. Instead of relying on software RNG that players cannot verify, the system uses cryptographic commitments and zero-knowledge proofs to generate and verify random token distribution, substituting unverified mechanical processes with mathematically provable cryptographic mechanisms.
2Extent of automation
If the server deals private tokens like hole cards, then dealing is automated, but players cannot be sure their cards are not leaked to opponents
Solution Approach 1:
The patent introduces cryptographic commitment schemes as intermediaries between the dealing process and players. Each player receives a cryptographic commitment to their private tokens that proves the tokens were dealt fairly without revealing them to the server or other players, maintaining privacy while enabling automated dealing.
Solution Approach 2:
The patent creates a cryptographically secure environment where private tokens remain hidden behind cryptographic commitments. This inert cryptographic layer protects private information from being leaked, allowing the server to handle dealing automatically while maintaining the confidentiality of private tokens through mathematical proofs rather than trust.
3Ease of operation
If players connect on a network for online gaming, then accessibility is improved, but collusion becomes harder to detect and easier to execute
Solution Approach 1:
The patent introduces verifiable random functions and cryptographic proofs as intermediaries that prevent colluding players from coordinating their strategies. Each player receives cryptographically verified random information that cannot be predicted or manipulated, making collusion ineffective even though players can easily connect online.
Solution Approach 2:
The patent replaces trust-based network gaming with cryptography-based verification. Instead of relying on network security or player honesty to prevent collusion, the system uses cryptographic commitments and zero-knowledge proofs to ensure each player receives fair, unpredictable private information that cannot be shared or coordinated among colluding parties.
4Reliability
If cryptographic protocols are implemented for verifiability, then fairness is improved, but system complexity increases
Solution Approach 1:
The patent segments the cryptographic verification process into distinct, modular components: commitment generation, commitment verification, token distribution, and proof validation. Each component handles a specific aspect of fairness verification, making the overall complex system manageable through clear separation of cryptographic functions.
