What is FHE? Why is it the superhero of AI?

Fully Homomorphic Encryption (FHE) is a revolutionary encryption technology that allows computation to be performed directly on encrypted data without the need for decryption.

In simple terms, data is locked in a “magic safe” throughout the entire computation process, and only the final result is unlocked. This means that privacy and computational efficiency can coexist — which is a godsend for AI.

The essence of AI is data-driven; whether training models or making inferences, vast amounts of data are required. However, data privacy and security have always been pain points for AI applications. The emergence of FHE is like giving AI an “invisible cloak,” allowing it to perform complex computations without exposing raw data. This not only enhances security but also opens doors for AI applications in sensitive areas.

How does FHE empower AI agents?

In the future AgenticWorld, millions of AI agents will collaborate like humans to perform tasks, trade assets, and reach consensus. FHE provides these agents with the following key capabilities:

Identity Verification: FHE supports the combination of zero-knowledge proofs (ZKP) and encrypted identities, allowing agents to verify each other's identities without exposing private keys or real identities.

Secure Environment: FHE provides agents with an “encrypted sandbox,” enabling them to operate securely in untrusted environments.

Decentralized and Verifiable Computing: FHE allows agents to perform verifiable encrypted computations on-chain, with results validated by network consensus.

Data Protection: The data processed by agents (transaction records, user preferences, etc.) is encrypted throughout, preventing data leakage or malicious use.

FHE is not only the pinnacle of encryption technology but also a catalyst for the fusion of AI and blockchain. It acts as an invisible bridge connecting privacy, security, and innovation. From the lifeline of healthcare to the trust foundation of DeFi, from fair competition in gaming to the collaboration of millions of agents in the AgenticWorld, FHE is everywhere. It allows us to boldly explore the digital universe without worrying about the cost of privacy.

As a ChainCrusader, I firmly believe: FHE is not just a technology, but a belief — a decentralized, privacy-centric future is beckoning us!
