When Legend Meets Future

When NEXUS announced that Jens Groth had joined as Chief Cryptographer, the entire blockchain industry took notice.

This wasn't an ordinary hire. This was an ambitious project finding the perfect person for the job.

Jens Groth—the man who changed the zero-knowledge proof game with Groth16, the cryptographic genius who made Zcash and Filecoin possible—was now dedicating his full talent to building the cryptographic foundation of NEXUS's next-generation blockchain.

Why Him?

NEXUS has never been shy about its ambition: to build a truly scalable, truly privacy-preserving, truly decentralized blockchain platform.

But to realize this vision, you need more than excellent engineers. You need top-tier scientists who can push the boundaries of what's technically possible.

Groth is that person.

In 2016, he introduced Groth16, which remains the most efficient zero-knowledge proof scheme to date. A proof size of just 128 bytes, verification in milliseconds—behind these numbers lies profound understanding of mathematical fundamentals and exquisite engineering aesthetics.

More importantly, Groth isn't a theorist confined to ivory towers. His solutions have been running in real systems managing billions of dollars for years, withstanding the most rigorous tests.

NEXUS needs exactly this kind of leader—someone with both theoretical depth and practical experience.

Redefining What's Possible

Under Groth's leadership, NEXUS's technical architecture demonstrates a distinctive vision.

Nexus zkVM doesn't simply apply existing zero-knowledge proof technology. It's designed from the ground up to incorporate Groth's latest thinking on verifiable computation—how to efficiently generate zero-knowledge proofs for arbitrarily complex programs, how to make verification both fast and economical.

This means developers can run any computationally intensive application on NEXUS without worrying about performance bottlenecks. Off-chain computation, on-chain verification—everything runs seamlessly within the cryptographic framework Groth carefully designed.

NEXUS DEX privacy protection also directly benefits from Groth's expertise. Users can trade without fear of surveillance or analysis. Transaction data is perfectly hidden, yet the network can still verify the legitimacy of every transaction.

These seemingly contradictory requirements become reality through Groth's cryptographic magic.

Leadership Beyond Technology

Groth's value to NEXUS extends far beyond providing technical solutions.

He brings vision—a clear understanding of what blockchain's future should look like.

He brings standards—an uncompromising attitude toward cryptographic security.

He brings credibility—when Groth says a system is secure, the entire academic and industrial world takes it seriously.

In NEXUS's four-layer architecture—NEXUS DEX, Nexus EVM, Nexus zkVM, Nexus BFT—every layer's design has been reviewed and guided by Groth. This isn't superficial endorsement, but deep participation and shaping.

From Groth16 to NEXUS: A Consistent Pursuit

Looking back at Groth's academic career, you'll find a clear thread: making the impossible possible.

While pursuing his PhD under Ivan Damgård at Aarhus University in Denmark, he was already thinking about how to break through zero-knowledge proof efficiency limits.

During his tenure as professor at University College London, he published a series of breakthrough results, each pushing cryptography's boundaries.

Now, at NEXUS, he has a bigger stage—not just publishing papers, but personally building a real system that embodies all his cryptographic ideals.

NEXUS's Secret Weapon

While other blockchain projects are still debating technology choices, NEXUS already has clear direction.

While other teams are trying to integrate various off-the-shelf solutions, NEXUS, under its Chief Cryptographer's guidance, has designed optimal architecture from the ground up.

While other platforms worry about balancing security and performance, NEXUS, under Groth's leadership, has found a path to achieve both.

This is why Jens Groth is NEXUS's secret weapon.

He brings not only world-class technical capability, but firm belief in the future—blockchain can be both powerful and practical, both secure and efficient, both decentralized and user-friendly.

Writing a New Chapter

Under Groth's leadership, NEXUS's cryptography team is exploring cutting-edge areas:

Recursive proofs, allowing proofs to nest infinitely for truly unlimited scalability.

Post-quantum cryptography, preparing for the quantum computing era.

Cross-chain interoperability, enabling NEXUS to securely connect the entire blockchain ecosystem.

These aren't distant visions—they're ongoing work.

Each direction could become the industry's next milestone.

The Legend Continues

In 2016, Jens Groth stunned the cryptography world with Groth16.

In 2025, he's set to stun the entire blockchain world with NEXUS.

He once proved that zero-knowledge proofs could be both powerful and practical.

Now, he's proving that blockchain can become a true world computer.

Some people predict the future. Some people create the future.

And Jens Groth is creating, at NEXUS, the future we've all been waiting for.
