FHE and Citizen Z: Reimagining the Vision for a New Era of Digital Sovereignty

In the new era driven by artificial intelligence and Web3, data has become the new wealth, while privacy protection faces unprecedented challenges. The emergence of Fully Homomorphic Encryption (FHE) technology shows us a path toward true digital sovereignty. Citizen Z embodies this vision, redefining what it means to be a responsible digital citizen.

In 2024, the arrest of Telegram founder Pavel Durov in France profoundly revealed the core issues of today’s internet: even platforms claiming to offer encrypted communication still have servers capable of decrypting user data, putting user information at risk of surveillance and malicious actors. This case marks a turning point—we must find a technology that prevents servers from accessing users’ plaintext data, even themselves.

The Privacy Crisis of the Internet: From Centralized Control

The evolution of the internet from HTTP to HTTPS marked progress in secure transmission. But today’s internet still has fundamental flaws: most platforms must decrypt user data to process it, creating conditions for data leaks and privacy violations.

As Edward Snowden pointed out at Token2049 in 2024: “If you don’t resist interference at the protocol level, eventually you will face interference.” This directly addresses the core issue—relying solely on corporate self-regulation or legal regulations is not enough. We need to fundamentally change how data is handled at the technical level.

Centralized internet architecture concentrates power excessively. Even Telegram, which claims end-to-end encryption, encrypts messages on the client but must decrypt on the server to process messages. This means law enforcement can compel platforms to hand over user communications for monitoring or investigation. In the age of AI, this vulnerability becomes even more dangerous.

HTTPZ Protocol: Building a New Foundation for an Encrypted Internet with FHE

The HTTPZ protocol proposed by ZAMA represents a paradigm shift—it makes Fully Homomorphic Encryption (FHE) the foundational protocol of the internet. FHE allows computations directly on encrypted data without decryption, ensuring servers can never see users’ plaintext information.

This is more than just a technical upgrade. If HTTPS brought us a secure internet and digital age, HTTPZ will lead us into the era of AI—an age where data is always protected by encryption, computations occur in ciphertext, and privacy and sovereignty belong entirely to users.

Core features of HTTPZ include:

• End-to-End Encryption: Data remains encrypted throughout its lifecycle, from message transmission to AI applications
• Encrypted Computation: Based on FHE, services can process encrypted data without decrypting
• Zero Trust Architecture: Replaces trust in third parties with cryptography, eliminating trust risks

Zama CEO Rand Hindi emphasizes: “FHE removes the biggest obstacle facing open data economies—lack of data security and sovereignty. With FHE, we can achieve superior AI, superior asset ownership, superior healthcare, and superior transactions.”

Citizen Z Identity: A Concrete Realization of Digital Sovereignty

In the era of HTTPZ, we need to redefine what it means to be a “digital citizen.” Citizen Z represents a new class of digital entities—fully sovereign individuals whose rights are protected by encryption rather than trust.

Four core characteristics of Citizen Z:

1. Universality: Anyone, regardless of identity, background, or belief, can become a Citizen Z and enjoy equal rights
2. Digital Sovereignty: Full ownership and control over personal data, speech, tokens, and other digital assets, free from intermediaries
3. Freedom of Expression: Rights to speak and vote without interference or surveillance
4. Technical Guarantees: All rights of Citizen Z are secured by cryptography provided by the HTTPZ protocol

Fhenix co-founder Guy Itzaki states: “Users’ digital lives are tightly controlled by centralized platforms. Through blockchain and FHE technology, Fhenix aims to restore this control, embodying the vision of digital sovereignty represented by Citizen Z.”

Future Applications Enabled by FHE

One of the most critical applications of digital sovereignty is encrypted voting. Under the HTTPZ framework, the voting process is revolutionized:

• Verifiability: Using zero-knowledge proofs to verify vote validity while protecting voter identity
• Encrypted Balloting: Counting votes via homomorphic encryption without intermediate decryption
• Tamper Resistance: Blockchain provides immutable voting records, ensuring transparency

This voting method is suitable for community governance, online consensus decisions, and even government elections—eliminating reliance on intermediaries.

Inco founder Remy Gay notes: “Looking at the broader history, the digital world is still in its early stages. When we look back, digital sovereignty will be seen as the foundation for building a sustainable and secure digital environment. Inco promotes blockchain adoption by supporting privacy capabilities, aligning closely with Mind Network’s Citizen Z plan.”

Similar FHE applications include:

• Financial Transactions: Clearing transactions without exposing amounts or participant identities
• Identity Verification: Authenticating identities without storing or revealing personal information
• Health Data: Medical information can be analyzed while maintaining patient privacy

Reimagining the Digital World: From Centralization to Sovereignty

The future built by Citizen Z and HTTPZ has four core dimensions:

Eliminating Intermediaries: Participation rights (like voting) no longer require third parties; individuals can directly engage in decision-making

Cryptographic Security: System security relies on mathematics, not trustworthiness of personnel, making it resistant to corruption

Full Transparency: Blockchain-based verifiable processes enable detection of any tampering

Personal Sovereignty: Rights over assets, data, and voting are entirely controlled by individuals

This is not just a technological iteration but a fundamental restructuring of digital social relations. Driven by AI and Web3, new organizational forms and network structures are emerging, with FHE and HTTPZ providing the essential infrastructure.

From data exchange to identity verification, from financial transactions to social governance, HTTPZ achieves comprehensive encryption at the protocol level, offering Citizen Z complete privacy and sovereignty protection. Every asset, piece of information, vote, identity, entertainment, work, and education in this future exists in data form—secured by FHE.

Join the HTTPZ Revolution: Digital Sovereignty Belongs to Everyone

We stand at a pivotal moment. In the AI-driven era, individuals are at the peak of productivity, and information is wealth. Our mission is to create a world where privacy, sovereignty, and autonomy are not privileges but fundamental human rights.

This is why we invite everyone who cares about unleashing the potential of a new era of global citizens to join the HTTPZ revolution. In this new world, digital sovereignty belongs to every Citizen Z, built on a zero-trust cryptographic foundation.

Through FHE technology and the Citizen Z concept, we are constructing a truly decentralized future—a digital society where everyone has full sovereignty and is free from intermediary interference. This is not just a technological upgrade; it is a redefinition of human digital freedom.
