While existing blockchain security systems are functioning effectively today, experts warn that the post-quantum era may expose their vulnerabilities, leaving critical digital infrastructure at risk. Addressing this challenge, Sharmila Rani Das, a recent graduate of the Computer Science and Engineering Department at World University of Bangladesh (WUB), has developed a hybrid post-quantum blockchain security system designed to withstand even the computational power of future quantum machines.
Her method integrates SPHINCS+ and NTRU, two advanced cryptographic algorithms, making blockchain transactions significantly more resilient — even in scenarios where conventional systems may fail. This groundbreaking innovation, supervised by Ahsan Ullah, Assistant Professor at WUB, has earned a place as a finalist at the BTRC Innovation Fair 2025.
With potential applications in digital governance, fintech, smart cities, and national ID systems, Sharmila’s work represents a vital step toward securing Bangladesh’s digital future. Analysts highlight that such innovations will play a key role in realizing the country’s vision of a Smart Bangladesh 2041, where robust and future-proof technology is essential.
