The world of blockchain technology continues to evolve at a rapid pace, with zero-knowledge proofs (ZKPs) emerging as one of the most transformative innovations in recent years. At Hong Kong Fintech Week 2023, Jeff Ren, Partner at OKX Ventures, took center stage during a fireside chat titled “Investing in Blockchain Infrastructure: The Zero-knowledge Revolution.” The session offered deep insights into how ZK technology is reshaping privacy, scalability, and trust in decentralized systems.
As blockchain moves beyond cryptocurrencies into real-world applications—from finance to identity management—infrastructure becomes the backbone of sustainable growth. Jeff Ren emphasized that investing in foundational technologies like zero-knowledge proofs isn't just forward-thinking—it's essential for long-term ecosystem resilience.
What Are Zero-Knowledge Proofs?
Zero-knowledge proofs are cryptographic methods that allow one party to prove to another that they know a value or statement is true—without revealing the actual information. For example, you can prove you’re over 18 without disclosing your birthdate.
This concept, once theoretical, has now matured into practical tools powering privacy-preserving transactions, secure identity verification, and efficient blockchain scaling solutions.

Core Applications of ZK Technology
Jeff Ren outlined several high-impact use cases where zero-knowledge proofs are already making a difference:
- Private Transactions: Public blockchains like Ethereum expose transaction details by default. ZK rollups and privacy layers enable users to transact securely without leaking sensitive financial data.
- Scalability Solutions: ZK rollups bundle thousands of transactions off-chain and submit a single cryptographic proof to the main chain, drastically reducing congestion and gas fees.
- Identity Verification: Users can authenticate credentials (e.g., citizenship, education) without exposing personal documents—ideal for decentralized ID systems.
- Compliance & Auditing: Institutions can verify regulatory compliance using ZK proofs without granting access to underlying customer data.
These applications are not speculative—they’re actively being deployed across DeFi, Web3 gaming, and enterprise blockchain solutions.
Why Invest in Blockchain Infrastructure Now?
According to Ren, early-stage investment in blockchain infrastructure offers outsized returns because it supports entire ecosystems rather than isolated applications.
“Think of it like building roads before cars,” he said. “You don’t just invest in the vehicle—you invest in the highway system that allows millions of vehicles to move efficiently.”
Infrastructure projects such as layer-1 blockchains, layer-2 scaling solutions, developer tooling, and cryptographic innovation form the foundation upon which user-facing apps are built. Without robust infrastructure, even the most innovative dApps will struggle with speed, cost, and security.
Moreover, with increasing institutional interest and regulatory clarity in regions like Hong Kong and Singapore, now is a pivotal moment for infrastructure development in Asia’s fintech landscape.
The Role of Venture Capital in Shaping the Future
OKX Ventures, as an early backer of numerous blockchain infrastructure projects, focuses on teams solving real technical challenges with long-term vision.
Ren highlighted three criteria they use when evaluating startups:
- Technical Depth: Founders must demonstrate deep understanding of cryptography, distributed systems, or consensus mechanisms.
- Problem-Solution Fit: The project should address a clear pain point—such as high transaction costs or lack of privacy—not create solutions in search of problems.
- Ecosystem Synergy: Projects that integrate well with existing chains or tooling have higher adoption potential.
He also noted that while hype cycles come and go, lasting value is created by builders focused on fundamentals—not short-term token price movements.
Challenges Facing ZK Adoption
Despite its promise, zero-knowledge technology still faces barriers:
- Complexity: Developing and auditing ZK circuits requires specialized knowledge, limiting the talent pool.
- Hardware Demands: Generating proofs can be computationally intensive, raising costs for some implementations.
- Interoperability: Different ZK systems often aren’t compatible, creating fragmentation across networks.
However, Ren remains optimistic. “We’ve seen similar challenges in earlier tech waves—from mobile computing to AI. With time, tooling improves, costs drop, and adoption accelerates.”
He pointed to emerging developer frameworks and open-source libraries that are lowering entry barriers for new builders.

FAQ: Understanding Zero-Knowledge Proofs and Blockchain Infrastructure
Q: What makes zero-knowledge proofs different from traditional encryption?
A: Traditional encryption hides data but requires decryption to verify it. ZKPs allow verification without revealing or decrypting the data itself—offering stronger privacy guarantees.
Q: Are ZK-based blockchains fully private?
A: Not always. Some implementations offer selective transparency for compliance purposes. True privacy depends on protocol design and user configuration.
Q: How do ZK rollups reduce fees on Ethereum?
A: By processing transactions off-chain and submitting only a small proof to Ethereum, ZK rollups minimize data usage—leading to lower gas costs and faster settlement.
Q: Can governments regulate ZK technology?
A: While regulation targets misuse (e.g., money laundering), many governments recognize the benefits of ZKPs for secure digital identity and data protection—making outright bans unlikely.
Q: Is now a good time to enter the ZK space?
A: Yes—especially for developers and investors focused on long-term infrastructure. The ecosystem is still early, with significant room for innovation and growth.
Q: How does OKX Ventures support early-stage blockchain projects?
A: Through funding, technical mentorship, ecosystem connections, and go-to-market strategy guidance—helping teams scale from concept to production.
The Road Ahead: Toward Mass Adoption
The future of blockchain hinges on solving three key challenges: scalability, security, and privacy. Zero-knowledge proofs uniquely address all three.
As more projects adopt ZK tech—from decentralized social networks to private healthcare records—the demand for scalable, auditable, and user-friendly infrastructure will surge.
Jeff Ren concluded his talk by urging builders to focus on utility over speculation. “The next decade won’t be about who made the most money fastest,” he said. “It’ll be about who built the most durable, inclusive, and trustworthy systems.”
With continued investment and innovation, zero-knowledge technology could become as ubiquitous as SSL encryption is today—running silently in the background, protecting data across the digital world.

Final Thoughts
The conversation at Hong Kong Fintech Week underscored a clear message: the future of blockchain is being built today—not on hype, but on hard technical progress. Zero-knowledge proofs represent more than a privacy feature; they are a foundational shift in how we verify truth in digital environments.
For developers, investors, and technologists alike, the takeaway is simple: get involved early, focus on fundamentals, and build for longevity.
As the ecosystem matures, those who invest in infrastructure now will shape the decentralized internet of tomorrow.
