AMA RECAP: Confidentiality, Privacy & the Future of Public Chains

Privacy in Web3 is no longer a niche conversation; it’s quickly becoming a foundational requirement. In this AMA, Ann Jiang sat down with Zama’s Co-Founder & CEO, Rand, to unpack how confidential computers are reshaping blockchain infrastructure, why privacy matters now more than ever, and what this unlocks for the future of on-chain finance.

Key Takeaways

Here are the main Key Takeaways:

• Privacy is not the opposite of blockchain—it’s the next evolution of it
• Confidential compute enables encrypted data to be processed without being exposed
• Institutional adoption is driving demand for privacy-first infrastructureFully Homomorphic Encryption (FHE) is now practical and production-ready
• The future of Web3 will combine transparency (verification) with confidentiality (data protection)

From Transparency to Confidentiality

Blockchains were never truly designed for full transparency—they were designed for integrity and public verifiability.Historically, verifying transactions required exposing all underlying data.

But that trade-off is no longer necessary.With advances like Fully Homomorphic Encryption (FHE):

• Data can remain encrypted
• Computations can still be verified publicly
• Trust is preserved without sacrificing privacy

Think of it as bringing HTTPS-level privacy to blockchain transactions

Why Privacy Matters Now

The urgency around privacy isn’t ideological—it’s practical.

As Rand explained, the biggest driver is simple: “Wall Street is moving on-chain—and finance requires confidentiality.”

Traditional finance systems:

• Keep balances private
• Protect transaction data
• Restrict visibility to authorized parties

Public blockchains, in their current state, don’t meet those expectations.

Without confidentiality:

• Institutions won’t onboard
• Large-scale capital won’t flow on-chain
• Real-world financial use cases remain limited

What is Confidential Compute (in simple terms)?

Confidential compute allows systems to process encrypted data without decrypting it first.

With FHE specifically:

• Data is encrypted before computation
• The system processes encrypted inputs
• Outputs remain encrypted
• No party ever sees raw data

This unlocks:

• Secure financial transactions
• Private smart contracts
• Confidential DeFi applications

Infrastructure Challenges (and Breakthroughs)

Privacy at the blockchain level isn’t just an app feature—it’s an infrastructure problem.

Zama spent years solving three major challenges:

1. Developer Experience

• FHE now integrates seamlessly with existing tools (e.g., Solidity, EVM wallets)
• Developers don’t need cryptography expertise to build

2. Performance

• Massive improvements (~1000x faster than early implementations)
• Now capable of running at scale without noticeable latency

3. Usability

• End users interact with apps exactly the same way
• Encryption happens behind the scenes
• Result: Confidential transactions feel no different from normal blockchain usage

Final Thoughts

This AMA made one thing clear: Privacy isn’t a “nice-to-have”—it’s a requirement for the next phase of blockchain adoption.By combining Public verifiability and Confidential data processing

We unlock a future where blockchain can support Global finance, Institutional capital, and Real-world applications at scale.
