## Abstract

This paper investigates the integration of blockchain technology within modern communication networks, focusing on the improvement of security, authentication, and resource allocation. As communication networks evolve toward 5G and beyond, the research examines how distributed ledgers can mitigate risks related to unauthorized access and network congestion. The author provides an extensive analysis of blockchain applications in edge computing and software-defined networking (SDN), demonstrating how smart contracts can automate network maintenance and service level agreements (SLAs). The study methodology includes a critical assessment of architectural requirements for integrating blockchain into network devices with constrained resources, such as those found in massive machine-type communications (mMTC). The findings underscore the importance of low-latency consensus protocols in real-time communication environments, providing a strategic outlook on the future convergence of distributed ledger technology and high-speed network infrastructure.
