Bangladesh researchers pioneer quantum-proof blockchain technology

Blockchain technology underpins modern digital finance, from cryptocurrency transactions to secure banking systems, making it the invisible backbone of our increasingly cashless economy. Quantum computing, whilst still emerging, represents a revolutionary leap in processing power that could potentially crack current encryption methods within minutes-posing an unprecedented threat to digital security worldwide.

Shormila Rani Das and her team from the World University of Bangladesh, under the guidance of Assistant Professor Ahsan Ullah, have developed an innovative framework to strengthen blockchain systems against emerging quantum computing threats. Their research combines SPHINCS+ and NTRU, two advanced post-quantum cryptography methods, offering enhanced protection for digital transactions.

Quantum computing poses a growing risk to traditional blockchain encryption, potentially affecting finance, supply chains, and digital services. The team's solution integrates SPHINCS+'s hash-based signatures with NTRU's lattice-based encryption, achieving over 95 per cent resistance against simulated quantum attacks whilst maintaining transaction efficiency.

This framework has significant applications for financial institutions, government digital services, and emerging fintech platforms in Bangladesh. By increasing trust and security in blockchain networks, the research could indirectly contribute to GDP growth by facilitating safer investment flows, e-commerce, and digital adoption across sectors.

The project aligns with key Sustainable Development Goals, particularly Industry, Innovation, and Infrastructure- SDG 9 and Decent Work and Economic Growth - SDG 8, promoting secure digital innovation and economic resilience in developing economies.

"This research highlights the potential of Bangladeshi talent to contribute to advanced cybersecurity solutions," said Shormila. "As quantum computing approaches, preparing secure blockchain frameworks today is essential for building a resilient digital economy tomorrow." The breakthrough demonstrates how local universities can address global technological challenges whilst positioning Bangladesh as a contributor to next-generation cybersecurity innovations.
