1. What is FHE? Why is it so important?
Fully Homomorphic Encryption (FHE) is a revolutionary encryption technology that allows computations to be performed without decrypting the data. This means:
• Data is encrypted throughout, ensuring that raw information is not exposed even during processing.
• Secure computing becomes possible, allowing industries such as AI, blockchain, and finance to truly achieve privacy protection.
In the future where AI and blockchain are deeply integrated, FHE will become the core infrastructure of a decentralized intelligent world, ensuring data security, trusted identities, and verifiable computations.
2. How does FHE empower AI? Key landing scenarios.
1) Healthcare: Privacy-secure AI diagnosis.
• Scenarios: Hospitals and research institutions can use FHE to encrypt patient data, allowing AI models to directly analyze encrypted data, avoiding the leakage of sensitive information.
• Advantages: Compliance (GDPR/HIPAA), prevention of data abuse, and secure collaboration across institutions.
2) DeFi: Secure, intelligent on-chain finance.
• Scenarios: FHE allows AI Agents to analyze user assets and credit risks in an encrypted environment, providing personalized investment advice while protecting transaction privacy.
• Advantages: Prevents MEV attacks, hides large holder positions, and enables confidential computing lending (such as DeFi protocols combining FHE and ZK).
3) Gaming: True digital asset ownership.
• Scenarios: Game AI can use FHE to analyze player behavior (such as preventing cheating and personalized recommendations) without accessing original data.
• Advantages: Protects player privacy while allowing AI to optimize the experience more intelligently.
4) AI Agent: A secure, decentralized network of intelligent entities.
In the future, there may be millions of AI Agents interacting autonomously, and FHE can provide:
• Identity verification: Encrypt to verify Agent identities, preventing malicious impersonation.
• Secure computing environment: Data exchanges between Agents are encrypted throughout.
• Verifiable computation: Ensures the AI decision-making process is auditable, avoiding black-box manipulation.
3. How does FHE construct a secure future for AI and blockchain?
1) AI and multi-chain collaboration: Secure cross-chain data.
• Issue: AI needs access to data across different chains, but traditional methods are prone to privacy leaks.
• FHE solutions: Computation under encryption, ensuring data is usable but not visible, for example:
• Cross-chain oracles: FHE protects price feed data from tampering.
• Agent consensus mechanism: AI Agents securely share information via FHE to reach decentralized decisions.
2) End-to-end encryption (E2EE) + FHE = Ultimate privacy protection.
• Why is it necessary? Traditional E2EE can only protect data in transit, while FHE enables encryption throughout storage and computation.
• Application cases:
• Privacy AI chatbots: Answer your questions without recording conversation content.
• Secure digital identity: Manage identity data with FHE, granting access only to necessary information.
3) DeCC (Decentralized Confidential Computing) and HTTPZ (Zero Trust Internet).
• FHE enables DeCC: Computation is performed on encrypted data, results can be verified, but the original data is not exposed.
• The future of HTTPZ: FHE can enhance zero-trust transmission, ensuring that data cannot be decrypted even if intercepted.
4. Will you authorize AI to access your data? How does FHE make authorization safer?
Most people are concerned about AI abusing data, but FHE can provide controlled authorization:
• Minimized disclosure: AI can only access encrypted data and cannot view the original information.
• Dynamic permission management: Temporary access rights can be set and will automatically expire.
• Auditability: All computations are verifiable, preventing AI from overstepping its authority.
Prerequisites:
Data is encrypted throughout (FHE + ZKP).
Decentralized identity (DID) controls access.
Smart contract manages authorization logic.
5. Conclusion: FHE - The encrypted moat of the future intelligent world.
In the wave of AI and blockchain integration, FHE is the key technology for privacy, security, and decentralization. It enables:
• AI is more trustworthy: Data is not leaked, and computations are verifiable.
• Blockchain is smarter: Confidential computing empowers DeFi, gaming, and social interactions.
• Users are safer: Truly in control of their data sovereignty.
The future Agentic World requires FHE as core infrastructure; otherwise, interactions among millions of AIs will be fraught with risks. Now, breakthroughs in FHE are making this vision possible.
