FHE is hailed as the 'Holy Grail' of cryptography, with its core advantage being the ability to perform computations directly on encrypted data without decryption, thereby achieving a perfect balance between data privacy and computational functionality. This article will explore how Mind Network leverages FHE to provide key use cases for AI and achieve landing applications in healthcare, finance (DeFi), gaming, and how FHE provides AI agents with necessary conditions for identity verification, secure environments, decentralization, verifiable computation, and data protection.
----------------------------------------------------------------
FHE use cases for AI: A new paradigm of privacy and autonomy
The core value of FHE lies in its ability to perform complex calculations without exposing the raw data, which is particularly important for the development of AI. The training, reasoning, and application of AI models often involve a large amount of sensitive data, such as personal health records, financial transactions, or user behavior data. Traditional AI systems typically require data to be centralized on servers for processing, which not only increases the risk of data breaches but may also violate privacy regulations (such as GDPR). FHE provides a revolutionary solution for AI in the following ways:
1. Encrypted reasoning and model training
FHE allows AI models to perform inference and training on encrypted data. For example, DeepSeek has integrated Mind Network's FHE Rust SDK, enabling its open-source models to perform secure inference on encrypted data, thereby protecting user data from unauthorized access risks. This technology is particularly critical for applications requiring high privacy protection, such as medical diagnostics or financial risk assessments.
2. Federated Learning

Mind Network's FHE infrastructure ensures that the data of all parties remains encrypted, sharing only encrypted model updates, thus achieving privacy-preserving collaborative learning. This has broad application potential in fields such as healthcare and DeFi.
3. Verifiable AI agent computation
In a decentralized AI ecosystem, AI agents need to autonomously perform tasks and collaborate with other agents. FHE ensures that the computational processes of agents are verifiable while protecting the privacy of their input data and computational results. For example, the ASI Hub developed by Mind Network in collaboration with SingularityNET utilizes FHE to provide verifiable randomness for AI agents, eliminating the risk of external manipulation and ensuring the transparency and fairness of AI systems.
4. Security of multi-agent collaboration
In multi-agent systems, FHE provides the foundation for encrypted communication and collaboration among agents. For example, Mind Network's MindChain is specifically designed for AI agents, supporting agents to conduct trust coordination and consensus computation in an encrypted environment, ensuring data security and computational fairness. This is crucial for scenarios requiring multi-party collaboration (such as medical research or DeFi strategy formulation).
