When designing solutions for certain problems, developers often face this dilemma: should they choose AI agents, cryptography, or game theory to build the system?

These three directions may seem vastly different, but in actual projects, they often all work. What's the difference? Is it whether your scenario values automation, security verification, or multi-party incentive balancing?

Interestingly, these three are not always mutually exclusive. A well-designed Web3 application can incorporate all three approaches—using game theory to design economic models, cryptography to ensure transaction security, and AI agents to optimize user experience. The key is to understand the core advantages and use cases of each approach.
