This paper analyses the emerging technology of the blockchain in the security of systems and the new developments made by software engineers to strengthen the pro-security measures. This research is based on a case of Ethereum and Bitcoin block transactions between 2015 and 2024; it evaluates the performance of these innovations in addressing crucial cybersecurity issues. The analysis identifies a notable increase in blockchain transactions, with the average number of transactions rising significantly from 6,808 in 2015 to 1,265,172 in 2021. Although there was a slight decline to an average of 1,119,292 in 2022 and 1,049,591 in 2023, the overall upward trend reflects growing adoption and utilization of blockchain technology. Some of the key insights identified show that these improvements like new consensus algorithms and scalability solutions have hugely improved the ability of the blockchain networks to handle moderate to high volumes of transactions without compromising the security of the networks. Technique adopted in this study is the descriptive and inferential statistics that reveals trends and patterns in the transaction data to analyse the effects of incorporating Blockchain technology in the modification and protection of data, access to the unauthorized person and strengthening the system. The study reveals a significant potential in the use of blockchain technology for deepening cyber security in its decentralized methodology and cryptosystem. For the future work, computational solutions should be advanced and should incorporate strategies that help increase scalability and enhance the roles of all the stakeholders involved in the process. Also, future research should uncover the organizational benefits and the use patterns of blockchain technology and investigate its interactions with other advanced technologies. From this study we appreciate the importance of blockchain in enhancing the cybersecurity and the need to advance and invest more in research and partnership to harness its benefits.
