BTQ Technologies launches quantum-secure blockchain consensus framework

BTQ Technologies Corp. (CBOE CA: BTQ) (OTCQX: BTQQF) announced the launch of Léonne, a blockchain consensus framework designed to address scalability, security, and decentralization challenges in distributed ledger technologies.

The Vancouver-based quantum technology company said Léonne introduces Topological Consensus Networks, which replaces Proof-of-Work and Proof-of-Stake mechanisms with a trust-based partitioning system called Proof-of-Consensus. The framework incorporates quantum-resistant cryptography and network analysis into a single system.

According to the company, Léonne features trust-based partitioning that restructures blockchain networks based on mathematical relationships between nodes, topological modeling using network theory, and quantum enhancements including Quantum Random Number Generation and Quantum Key Distribution.

"As blockchain infrastructure becomes increasingly mission-critical—for finance, supply chains, healthcare, and more—networks must be efficient, secure, and resilient," said Olivier Roussy Newton, CEO of BTQ Technologies. "Léonne directly addresses these demands while anticipating future risks posed by quantum computing and centralization trends."

The framework is designed with linear algorithmic complexity to enable consensus across networks with minimal computational overhead. BTQ said the modular architecture allows integration with existing blockchain platforms and emerging quantum hardware.

BTQ Technologies plans to engage with industry partners, academic collaborators, and select clients to deploy Léonne in test environments and pilot programs during the second half of 2025.

The company describes itself as a vertically integrated quantum company developing hardware, middleware, and post-quantum security solutions for finance, telecommunications, logistics, life sciences, and defense sectors.
