Research on the Possibility of Using Blockchain Technology for Number Portability Databases

Abstract

Oleg Khovayko

Number Portability Databases (NPDB) play a pivotal role in modern telecommunications by facilitating the seamless transfer of phone numbers between service providers. However, traditional NPDB systems face significant challenges, including centralization, high costs, and security vulnerabilities. This paper proposes a novel approach leveraging blockchain technology through the ENUMER system. ENUMER, designed initially to enhance ENUM operations, demonstrates a unique suitability for NPDB tasks due to its decentralized architecture, enhanced security, and cost efficiency. Our study involved testing ENUMER on standard hardware to ensure results stem from architectural advantages rather than high-performance equipment. The findings reveal sub-millisecond retrieval times and rapid record updates, showcasing ENUMER’s potential to outperform traditional NPDB systems. Although direct comparison data from existing NPDBs is scarce, our results suggest that ENUMER can serve as both an immediate solution and a foundation for future NPDB developments. For example, integrating public key infrastructure for caller ID verification could further enhance its functionality. This research highlights ENUMER’s capability to address current NPDB limitations and offers a promising direction for future improvements in telecom infrastructure.
