A Note from EternaX / Introducing Our Chief Scientist

Dr. Chen Feng, Chief Scientist at EternaX: SILMARILS, Post-Quantum Cryptography, and the Scientific Foundation of EternaX

At EternaX, we are building post-quantum market infrastructure for institutional finance. That work rests on a scientific foundation. Today, we are introducing the scientist behind it, and the post-quantum signature scheme that carries his name in the acknowledgements.

At EternaX, we believe post-quantum market infrastructure must be built on science that is real, peer-reviewed, and durable. When we set out to design a post-quantum signature scheme capable of preserving institutional execution quality, a scheme we named SILMARILS, we knew the research had to be led by someone whose work in quantum computing, post-quantum cryptography, and information theory was already recognised at the highest level. That scientist is Dr. Chen Feng, our Chief Scientist. He joins our co-founders Paarrthhh Birla and Dariia Porechna as the third signatory on every piece of EternaX institutional research, including our April 2026 Cryptographic Migration Debt framework and our Q1 2026 Already Broken report. This page is our formal introduction.

Dr. Chen Feng is Associate Professor in the School of Engineering at UBC Okanagan, Tier-2 Principal's Research Chair in Blockchain, and Co-Cluster Lead of Blockchain@UBC. In April 2026, he received two NSERC Alliance International Catalyst Quantum grants, and was the only researcher in that national round to receive multiple Alliance Quantum awards. In January 2025, he received a $165,186 NSERC quantum grant for error-correcting code research in collaboration with Xanadu, the Canadian photonic quantum computing company. His publication record spans Nature Communications, npj Quantum Information, IEEE Transactions on Information Theory, and the IEEE Symposium on Security and Privacy. This is the foundation beneath SILMARILS and EternaX.

Section 1SILMARILS, and the Science Behind It

We commissioned SILMARILS because the existing post-quantum signature standards, ML-DSA, SLH-DSA, and FN-DSA (Falcon), all impose signature sizes that are 10 to 122 times larger than current Ed25519 and secp256k1 standards, with proportional throughput losses. Project Eleven and the Solana Foundation confirmed in live testnet in April 2026 that Solana running quantum-resistant signatures loses approximately 90% of its throughput. Circle's Arc chose SLH-DSA-SHA2-128s at 7,856 bytes per signature, which is 49 times larger than SILMARILS. If institutional finance is to be both post-quantum and market-speed, a different construction was required.

Co-authored by Dr. Chen Feng, Dariia Porechna, and collaborators. Under full post-quantum migration, EternaX using SILMARILS operates at approximately 2% throughput loss, against 31% modelled for Ethereum and 90% confirmed in live Solana testnet.

Dr. Feng's academic work sits directly in the research lineage that produced SILMARILS. His 2024 Canadian Workshop on Information Theory paper, NIROPoK-Based Post-Quantum Sidechain Design on Ethereum, with Hassan Khodaiemehr, developed non-interactive random oracle proof of knowledge constructions for post-quantum sidechain design. His April 2026 NSERC grant on Post-Quantum Weighted Threshold Signatures Based on Random Oracle Proof of Knowledge extends that line of work. SILMARILS, his NSERC-funded research, and his peer-reviewed publication record are expressions of one continuous scientific programme.

Section 2The April 2026 NSERC Alliance Quantum Double Award

On April 16, 2026, UBC Okanagan announced that Dr. Feng had received two NSERC Alliance International Catalyst Quantum grants, valued at $25,000 each. He was one of four UBC researchers funded in that national competition, and the only researcher in the round to receive multiple Alliance Quantum grants. The two funded projects are Post-Quantum Weighted Threshold Signatures Based on Random Oracle Proof of Knowledge, and Efficient Multi-Mode GKP Codes for Photonic Quantum Computing.

These project titles matter for EternaX. Post-quantum threshold signatures are a direct design ingredient for institutional-grade custody, multi-party settlement, and regulated digital asset infrastructure, which is precisely the workflow we are built for. GKP codes and fault-tolerant photonic quantum computing define the attack surface that our product stack is architected to survive. In Dr. Feng's own words from the UBC announcement:

"These projects are about building trust in the next generation of computing systems. By combining rigorous theory with practical design, we aim to make quantum and cryptographic technologies both secure and deployable in real-world settings." Dr. Chen Feng, UBC Okanagan announcement, April 16, 2026

Section 3The Broader Record

The April 2026 double award is not Dr. Feng's first NSERC quantum recognition. In January 2025, he received $165,186 over two years from NSERC for quantum error-correcting code research with Xanadu. He was the only recipient from the UBC Okanagan campus in that round. Together, the 2025 and 2026 grants span both sides of the post-quantum problem: the hardware trajectory that determines how quickly usable quantum computers arrive, and the cryptographic constructions that must survive them. Very few researchers work on both sides at once.

His peer-reviewed publication record anchors that research programme. He has published in Nature Communications on experimental quantum fingerprinting (2015), in Nature Partner Journal Quantum Information on quasi-cyclic multi-edge LDPC codes for long-distance quantum cryptography (2018), in IEEE Transactions on Information Theory on algebraic physical-layer network coding (2013), in IEEE Transactions on Dependable and Secure Computing on multiple BFT consensus protocols for blockchains, in IEEE Journal on Selected Areas in Communications on coherent-state QKD security (2025), and in the 2025 IEEE Symposium on Security and Privacy on TreePIR, a private retrieval scheme for Merkle proofs accepted at a 14.3% acceptance rate. He received his PhD from the University of Toronto under Professors Frank Kschischang and Baochun Li, and held postdoctoral positions at EPFL with Professor Michael Gastpar and at Boston University with Professor Bobak Nazer.

Section 4Why This Matters for Our Partners

As we argue in our April 2026 Cryptographic Migration Debt framework, after NIST's 2024 finalisation of post-quantum standards, Google's March 30, 2026 paper compressing the qubit threshold for breaking Bitcoin and Ethereum's cryptography by approximately 20-fold, and Project Eleven's April 2026 live testnet confirming a 90% throughput loss on Solana under NIST post-quantum migration, every new issuance of long-duration institutional value on a non-PQ-safe rail is a knowing choice. Institutions evaluating EternaX will ask whether our scientific foundation is real. Dr. Chen Feng's NSERC quantum funding, Tier-2 Principal's Research Chair in Blockchain, and peer-reviewed publication record constitute a foundation that is independently verifiable. SILMARILS is not a marketing claim. It is a scientific construction co-authored by our Chief Scientist, with a peer-reviewed publication pathway into the IACR Journal of Cryptology.

For researchers, journalists, and students discovering Dr. Feng's work, EternaX is where his research is operationalised into live market infrastructure. Our testnet launched in November 2025 has processed over 1,000,000 transactions and over 475,000 prediction market bets, with approximately 120 millisecond finality. The 160-byte SILMARILS signature scheme is not a slide in a presentation. It is a deployed PQ-native Layer 1 with public traction.

The two-way association

Dr. Chen Feng's academic authority gives EternaX its scientific foundation. EternaX gives Dr. Feng's research its most consequential applied expression. SILMARILS is what that bridge produces. When the IACR Journal of Cryptology publishes the SILMARILS paper, we expect it to be discovered alongside this page.

We are privileged to have Dr. Feng as our Chief Scientist, and we are proud to publish this introduction. For institutional counterparties, researchers, and partners who would like to discuss SILMARILS, EternaX's product stack, or our institutional research, please reach out at info@eternax.ai.
