Splendor Labs SA launched Splendor Quantum Chain on September 25, 2026, establishing the world’s first live Layer-1 blockchain integrating ML-DSA-65 signatures, ML-KEM-768 network security, dual ML-DSA/SLH-DSA verification, and RLNC-based data transport in a single post-quantum architecture. The new network anticipates the evolving threat of quantum computing to digital ownership and transaction security, positioning itself as foundational infrastructure for both decentralized finance and emerging applications in artificial intelligence.

“We designed Splendor Quantum Chain around where we believe digital infrastructure is going, not simply where it is today,” said Todor Ivanov, Founder and CEO of Splendor Labs SA, as major institutions like BlackRock, J.P. Morgan, and Fidelity develop initiatives for real-world asset tokenization.

This combination places quantum-resistant protection directly into the network’s core functions, covering transaction signing, node communication, verification layers, and data distribution. The architecture’s development used patent-pending technology designed to preemptively address vulnerabilities arising from the anticipated progression of cryptographically relevant quantum computing. This proactive approach differs from strategies that treat post-quantum security as a future upgrade to existing systems. The network’s design also anticipates the increasing intersection of blockchain technology and traditional finance, a convergence driving demand for secure, scalable infrastructure.

Institutions including BlackRock, J.P. Morgan, Goldman Sachs, Citi, Franklin Templeton and Fidelity are actively developing initiatives for digital asset tokenization, with a focus on representing real-world assets like real estate, funds, and bonds on blockchain networks. Splendor Quantum Chain provides the foundational infrastructure for these applications, offering programmable assets, native token functionality, and verifiable settlement capabilities, all secured by its post-quantum cryptographic layers.

SPLD functions as the network’s native coin, facilitating transactions and incentivizing network participation. “We built the technology to address those requirements at the protocol level, and the network is now live.” Beyond finance, the same architecture is intended to support emerging applications in artificial intelligence and autonomous software, where secure authentication, value exchange, and verifiable records are paramount.

Splendor Labs SA is now focused on expanding its ecosystem with applications spanning real-world asset tokenization, digital finance, quantum-secure payments, AI, and rewards programs, all built on the Splendor Quantum Chain. “Our next phase is focused on the products and applications that can be built on this foundation.”

We designed Splendor Quantum Chain around where we believe digital infrastructure is going, not simply where it is today.

Ivy Delaney

Ivy Delaney has been working with neural networks and machine learning since the mid-nineties, back when a couple of hidden layers and a long afternoon of training counted as ambitious. She has watched the field go from academic curiosity to the thing quietly running underneath everything, and she brings that long view to quantum computing. For Quantum Zeitgeist she covers the ground where the two fields meet. That means quantum machine learning and the variational algorithms it leans on, and it also means the less glamorous but more interesting story of classical machine learning already doing real work inside quantum machines, decoding error-correcting codes, calibrating noisy hardware and learning the error models that simulators depend on. She writes about the hardware those algorithms have to run on too, and about the post-quantum cryptography scramble that the same hardware has set off. Her stories typically start with the paper, whether that is peer-reviewed work, conference proceedings or an arXiv preprint, with the source linked so you can hold a claim up against the research it came from. She is unimpressed by benchmarks that will not say what they beat, and by demonstrations that only work in the press release.
