Protected by Design
Proof of Coherence is the product of years of original research at the intersection of quantum mechanics and distributed systems. We protect that work the same way we build it: deliberately, and in layers.
Three patent applications filed with the USPTO. One architecture built to stay verifiable by anyone, yet reproducible by no one.
Our Patent-Pending Portfolio
Three patent applications cover the core innovations behind Proof of Coherence. All three are patent pending with the United States Patent and Trademark Office.
1. Quantum Proof-of-Coherence Blockchain Validation System
App. No. 19/711,486Filed June 2026, claiming June 2025 priority
A quantum-native blockchain validation system that utilizes Proof-of-Coherence (PoCoh) to achieve self-validating blocks without traditional consensus mechanisms. The system embeds quantum signatures demonstrating non-classical behavior in block headers, enabling deterministic validation in sub-millisecond time using classical computation.
2. Distributed Ledger Validation Using Classically-Intractable Quantum Phenomena
App. No. 19/702,980Filed June 2026, claiming June 2025 priority
A comprehensive framework for distributed ledger validation using classically-intractable quantum phenomena. The system enables blockchain validation through quantum advantages including Bell inequality violations, quantum supremacy demonstrations, certified randomness, and entanglement witnesses. The framework provides a unified architecture in which quantum hardware generates unforgeable proofs that are verified using classical computation.
3. Computational Entanglement System for Persistent Agent Identity Verification and Protection
App. No. 19/707,649Filed June 2026, claiming June 2025 priority
A computational entanglement system for verifying and protecting persistent agent identity. The system establishes an authenticated bidirectional binding between a user and a persistent computational agent.
Coming December 2026
Under standard USPTO procedure, our applications will be published and available in the public record. When they are, we’ll link the full publication documents here, with every claim open for inspection.
What We Open. What We Protect. And Why.
Most companies treat their technology stack as all-or-nothing: fully open source, or a total black box. We’ve drawn a more deliberate line.
Open: the verifier.
Anyone can check a PoCoh-validated block. The verification layer is designed for public legibility. You don’t need to trust us, our hardware, or our intentions to confirm that validation happened and that the physics checks out. A consensus mechanism you can’t independently verify isn’t consensus at all.
Verify a block yourself →Protected: the generation process.
How coherent states are generated at the genesis of validation is held as a trade secret, behind the boundary of our filed patent claims. This isn’t secrecy for its own sake. It’s the standard structure of durable IP: publish what makes the system trustworthy, protect what makes it ours.
This wall between the open verifier and the protected generation layer is intentional, permanent, and we’d argue it’s the reason you can take PoCoh seriously. You can verify everything we claim without us revealing everything we know.
Not Just Theory
The demonstrations on this site run against a live quantum blockchain backend. The post-quantum security demo calls real infrastructure in real time. Our IP filings describe technology that exists and operates today, not a roadmap.

Fine Print
QBLEX technologies described on this site are patent pending. “Patent pending” indicates that one or more patent applications have been filed with the USPTO and are awaiting examination; it does not indicate that a patent has been granted. Certain aspects of QBLEX technology are additionally protected as trade secrets and are not disclosed in any public filing. Nothing on this page constitutes legal advice or a warranty of patent scope.
