Quantum-Resistant Blockchain Launches with Post-Quantum Cryptographic Layers
Splendor Labs SA has launched Splendor Quantum Chain, a blockchain designed to withstand quantum attacks. The network went live on September 25, 2026, and is the first live Layer-1 blockchain integrating post-quantum cryptographic layers. According to Todor Ivanov, Founder and CEO of Splendor Labs SA, 'We designed Splendor Quantum Chain around where we believe digital infrastructure is going, not simply where it is today.'
The network's architecture combines 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. This places quantum-resistant protection directly into the network's core functions, covering transaction signing, node communication, verification layers, and data distribution.
The Splendor Quantum Chain provides foundational infrastructure for decentralized finance and emerging applications in artificial intelligence. It also supports real-world asset tokenization, with institutions like BlackRock, J.P. Morgan, Goldman Sachs, Citi, Franklin Templeton, and Fidelity developing initiatives for digital asset tokenization.
