Blockchain technology has garnered considerable interest in recent times, thanks to its decentralized and unchanging characteristics, rendering it a prime foundation for trustworthy and open dealings. Nevertheless, safeguarding privacy and enhancing authorization systems stand as pivotal elements demanding attention for the widespread integration of blockchain into real-world applications. This research paper focuses on exploring the implementation of a security-based blockchain system that enhances privacy and authorization mechanisms in real-time applications. We analyse the challenges associated with privacy and authorization in blockchain and propose novel solutions to address these issues. Our research highlights the importance of cryptographic techniques, consensus algorithms, and smart contract design to achieve a secure and efficient blockchain system. Additionally, we evaluate the performance of our proposed system through experimentation and discuss the implications for real-time applications.
